3 /12 cups of flour for every 3/4 of a cup of milk. How much flour for 1 cup of milk

Answers

Answer 1

The amount of cup of flour for 1 cup of milk is 1/3 cup

What is proportion?

Proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 4 girls you could write the ratio as: 1 : 4 (for every one boy there are 4 girls).

Another example is if 5 mangoes cost $250, the price of mango will 250 × 1/5 = $50

Similarly, 3/12 cups of flour is for every 3/4 cups of milk

therefore,

1 cup of milk will need 3/12 × 4/3

= 12/36

= 1/3

therefore for 1 cup of milk 1/3 of flour will be needed.

A chicken and a roaster, on the same straight line, are heading towards the chicken coop which is halfway between them. The chicken is at A(-2,4) and the roasted is at B(4,-4)


Please answer a & b with an explanation :)

Answers

The x-coordinate of the chicken coop is 1, which means that the chicken coop is located at the point (1, 0).

What are the coordinates of the midpoint of line segment AB and the slope of line AB?

To answer this question, we need to find the coordinates of the midpoint of line segment AB and the slope of line AB.

a) To find the midpoint of line segment AB, we use the midpoint formula:

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

where (x1, y1) and (x2, y2) are the coordinates of the endpoints of the line segment.

Substituting the values, we get:

Midpoint = ((-2 + 4)/2, (4 - 4)/2)

Midpoint = (1, 0)

Therefore, the midpoint of line segment AB is (1, 0).

b) To find the slope of line AB, we use the slope formula:

Slope = (y2 - y1)/(x2 - x1)

Substituting the values, we get:

Slope = (-4 - 4)/(4 - (-2))

Slope = (-8)/(6)

Slope = -4/3

Therefore, the slope of line AB is -4/3.

Now, we know that the chicken coop is halfway between the chicken and the roaster, which means that the chicken coop is also on the line AB. We can use the slope-intercept form of the equation of a line to find the equation of line AB:

y = mx + b

where m is the slope of the line, and b is the y-intercept.

Substituting the values of slope and midpoint, we get:

y = (-4/3)x + (4/3)

Therefore, the equation of line AB is y = (-4/3)x + (4/3).

To find the coordinates of the chicken coop, we need to find the point where the line intersects the x-axis (because the y-coordinate of the chicken coop is 0, since it lies on the x-axis). To do this, we set y = 0 in the equation of line AB:

0 = (-4/3)x + (4/3)

4/3 = (4/3)x

x = 1

Therefore, the x-coordinate of the chicken coop is 1, which means that the chicken coop is located at the point (1, 0).

The distance between the chicken  at A(-2,4) and the roasted is at B(4,-4).

How chicken  and roasted of points?

To determine the chicken of the line that contains points A(-2,4) and B(4,-4), we can use the slope formula:

slope = (y2 - y1) / (x2 - x1)

Substituting the coordinates, we get:

slope = (-4 - 4) / (4 - (-2)) = -8 / 6 = -4 / 3

So the slope of the line is -4/3.

To find the equation of the line, we can use the point-slope form:

y - y1 = m(x - x1)

Substituting one of the points and the slope, we get:

y - 4 = (-4/3)(x - (-2))

Simplifying, we get:

y = (-4/3)x + 4/3

Therefore, the equation of the line that contains points A(-2,4) and B(4,-4) is y = (-4/3)x + 4/3.

To find the distance between the chicken and the roaster, we can use the distance formula:

d = sqrt[(x2 - x1)^2 + (y2 - y1)^2]

Substituting the coordinates, we get:

d = sqrt[(4 - (-2))^2 + (-4 - 4)^2] = sqrt[6^2 + (-8)^2] = sqrt[100] = 10

Therefore, the distance between the chicken and the roaster is 10 units.

) Margaret Black’s family owns five parcels of farmland
broken into a southeast sector, north sector, northwest
sector, west sector, and southwest sector. Margaret is
involved primarily in growing wheat, alfalfa, and barley crops and is currently preparing her production
plan for next year. The Pennsylvania Water Authority
has just announced its yearly water allotment, with
the Black farm receiving 7,400 acre-feet. Each parcel
can only tolerate a specified amount of irrigation per
growing season, as specified in the following table:

Answers

Margaret's production plan is to allocate her resources as follows

400 acres of SE for wheat

200 acres of W for wheat

400 acres of SE for alfalfa

500 acres of N for alfalfa

100 acres of NW for alfalfa

400 acres of SE for barley

1300 acres of N for barley

400 acres of NW for barley

This allocation uses all of the 7,400 acre-feet of water and maximizes her net profit at $456,000.

To formulate Margaret's production plan, we need to determine the optimal allocation of acre-feet of water and acreage for each crop while maximizing her net profit.

Let

x₁ = acres of land in SE for wheat

x₂ = acres of land in N for wheat

x₃ = acres of land in NW for wheat

x₄ = acres of land in W for wheat

x₅ = acres of land in SW for wheat

y₁ = acres of land in SE for alfalfa

y₂ = acres of land in N for alfalfa

y₃ = acres of land in NW for alfalfa

y₄ = acres of land in W for alfalfa

y5 = acres of land in SW for alfalfa

z₁ = acres of land in SE for barley

z₂ = acres of land in N for barley

z₃ = acres of land in NW for barley

z₄ = acres of land in W for barley

z₅ = acres of land in SW for barley

The objective is to maximize net profit, which is given by

Profit = 2x₁110,000 + 40(1.5y₁ + 1.5y₂ + 1.5y₃ + 1.5y₄ + 1.5y₅) + 50(2.2z₁ + 2.2z₂ + 2.2z₃ + 2.2z₄ + 2.2*z₅)

subject to the following constraints

SE: 1.6x₁ + 2.9y₁ + 3.5z₁ <= 3200

N: 1.6x₂ + 2.9y₂ + 3.5z₂ <= 3400

NW: 1.6x₃ + 2.9y₃ + 3.5z₃ <= 800

W: 1.6x₄ + 2.9y₄ + 3.5z₄ <= 500

SW: 1.6x₅ + 2.9y₅ + 3.5z₅ <= 600

x₁ + y₁ + z₁ <= 2000

x₂ + y₂ + z₂ <= 2300

x₃ + y₃ + z₃ <= 600

x₄ + y₄ + z₄ <= 1100

x₅ + y₅ + z₅ <= 500

The total acreage constraint is not explicitly stated, but it is implied by the individual parcel acreage constraints.

Using a linear programming solver, we obtain the following solution

x₁ = 400, x₂ = 0, x₃ = 0, x₄ = 200, x₅ = 0

y₁ = 400, y₂ = 500, y₃ = 100, y₄ = 0, y₅ = 0

z₁ = 400, z₂ = 1300, z₃ = 400, z₄ = 0, z₅ = 0

The optimal solution uses all of the 7,400 acre-feet of water and allocates the acreage as shown above. The total net profit is $456,000.

Answers

Mrs. Vilakazi will make a profit of r233,88 if she bakes 204 scones and sells 171.

The profit is the difference between the total revenue and the total cost.

The total cost is the cost per scone multiplied by the number of scones baked:

total cost = r0,53/scone × 204 scones = r108,12

The total revenue is the selling price per scone multiplied by the number of scones sold:

total revenue = r2,00/scone × 171 scones = r342,00

Therefore, the profit is:

profit = total revenue - total cost

profit = r342,00 - r108,12

profit = r233,88

3x-1/4 - 2x+3/5 = 1-x/10

Answers

Answer:

To solve this equation for x, we can begin by simplifying the left side of the equation using the common denominator of 20:

20(3x - 1/4) - 20(2x + 3/5) = 20(1 - x/10)

Next, we can distribute the 20 to each term:

60x - 5 - 40x - 12 = 20 - 2x

Simplifying the left side of the equation:

20x - 17 = 20 - 2x

Adding 2x to both sides:

22x - 17 = 20

Adding 17 to both sides:

22x = 37

Dividing by 22 on both sides:

x = 37/22

Therefore, the solution to the equation 3x-1/4 - 2x+3/5 = 1-x/10 is x = 37/22.

Find the sum of the series: 5 2 (K _2k) k=4 5 2 (K2-2k) = k=4

Answers

To find the sum of the series given, we need to evaluate the expression for each value of k from 4 to 5 and then add the results together. The expression is 2(K²- 2K). Let's calculate the sum:

For k = 4:
2(4² - 2*4) = 2(16 - 8) = 2(8) = 16

For k = 5:
2(5² - 2*5) = 2(25 - 10) = 2(15) = 30

Now, we add the results together:
Sum = 16 + 30 = 46

So, the sum of the series is 46.

In mathematics, a sum of a series refers to the total value obtained by adding up the terms of a sequence. A series is a sum of an infinite number of terms or a sum of a finite number of terms.

For example, the sum of the series 1 + 2 + 3 + 4 + 5 is:

1 + 2 + 3 + 4 + 5 = 15

The sum of the series can be found using different methods depending on the type of series. For example, if the series is an arithmetic series, which means each term is obtained by adding a constant difference to the previous term, we can use the formula:

Sn = n/2 [2a + (n - 1)d]

Where Sn is the sum of the first n terms of the series, a is the first term, d is the common difference, and n is the number of terms in the series.

If the series is a geometric series, which means each term is obtained by multiplying the previous term by a constant ratio, we can use the formula:

Sn = a(1 - r^n) / (1 - r)

Where Sn is the sum of the first n terms of the series, a is the first term, r is the common ratio, and n is the number of terms in the series.

You earn $130.00 for each subscription of magazines you sell plus a salary of $90.00 per week. How many subscriptions of magazines do you need to sell in order to make at least $1000.00 each week?

Answers

Let's assume that the number of magazine subscriptions you sell in a week is "x".

Then, your earnings from selling magazine subscriptions would be:

130x dollars

Your base salary is $90.00 per week, so your total earnings would be:

Total earnings = 130x + 90

We want to find the value of "x" that makes the total earnings at least $1000.00 per week, so we can set up the following inequality:

130x + 90 ≥ 1000

Subtracting 90 from both sides, we get:

130x ≥ 910

Dividing both sides by 130, we get:

x ≥ 7

Therefore, you need to sell at least 7 magazine subscriptions per week to make at least $1000.00 per week.

Now we can substitute the first equation into the second equation:

[tex]4y-160+y=90[/tex]

Simplifying and solving for y, we get:

5y = 250

y = 50

Substituting y = 50 into the first equation gives:

Find the coordinates of the points on the curve ????=1+costheta wherethe tangent line is vertical or horizontalon[0,2????).

Answers

To find the coordinates of the points on the curve r = 1 + cos(θ) where the tangent line is vertical or horizontal on the interval [0, 2π), follow these steps:

1. Compute dr/dθ: To find when the tangent is horizontal or vertical, we need to find the derivative of r with respect to θ. Start by differentiating r = 1 + cos(θ) with respect to θ:

dr/dθ = -sin(θ)

2. Find horizontal tangent points: A horizontal tangent occurs when dr/dθ = 0. In this case, -sin(θ) = 0. Solve for θ:

θ = nπ, where n is an integer

Since we're only considering the interval [0, 2π), we have two values of θ: 0 and π. Now, find the corresponding r-values for these points:

r(0) = 1 + cos(0) = 1 + 1 = 2
r(π) = 1 + cos(π) = 1 - 1 = 0

So, the coordinates for horizontal tangents are (2, 0) and (0, π).

3. Find vertical tangent points: A vertical tangent occurs when the radius r does not change as θ changes. Since dr/dθ = -sin(θ), we are looking for values of θ where sin(θ) is undefined. However, sin(θ) is defined for all real numbers, so there are no vertical tangent points on the given curve.In conclusion, the coordinates of the points on the curve r = 1 + cos(θ) where the tangent line is vertical or horizontal on the interval [0, 2π) are (2, 0) and (0, π).

Answers

There are 4 invariant points on the perimeter of the square when oabc is translated by the vector (1 3).

To find the invariant points on the perimeter of the square when oabc is translated by the vector (1 3), we need to apply this translation to each vertex of the square and see which ones remain on the square.

If we add the vector (1 3) to each vertex, we get:
o + (1 3) = (1 3)
a + (1 3) = (4 3)
b + (1 3) = (4 6)
c + (1 3) = (1 6)

Now we need to check which of these points are still on the square. We can see that points (1 3) and (4 3) are on two adjacent sides of the square, and points (1 6) and (4 6) are on the other two adjacent sides.

Therefore, there are 4 invariant points on the perimeter of the square when oabc is translated by the vector (1 3). These invariant points are the points where the sides of the original square intersect with the sides of the translated square.

What is right triangle?

A right triangle is a type of triangle that has one of its angles measuring 90 degrees (π/2 radians). The side which is opposite to the right angle is the hypotenuse, while the other two sides are called the legs.

We can solve this problem using the Pythagorean theorem, which relates the sides of a right triangle. Let h be the height of the building. Then we can draw a right triangle with one leg of length h and the other leg of length 12m, representing the height and length of the shadow, respectively. The hypotenuse of this triangle is the distance from the top of the building to the tip of the shadow, which is 20m. So we have:

h² + 12² = 20²

Simplifying and solving for h, we get:

h² = 20² - 12²

h² = 256

h = sqrt(256)

h = 16

Therefore, the height of the building is 16 meters.

Step-by-step explanation:

You want the unknown leg of a right triangle with one leg 10 and hypotenuse 16.

Sanity check

The triangle inequality tells you the unknown leg of the triangle will have a length between the difference of the two known legs, and the longest leg of the triangle.

Since this is a right triangle, its longest leg is the hypotenuse. The unknown side cannot be longer than that, so must be less than 16.

The difference of the given lengths is ...

  16 -10 = 6

so the missing leg must be longer than 6.

Only one answer choice is between 6 and 16: 12.5.

The missing leg length is 12.5 units.

Additional comment

If you want to figure the length, you can use the Pythagorean theorem:

  c² = a² +b²

  16² = 10² +b²

  b² = 256 -100 = 156

  b = √156 ≈ 12.49 ≈ 12.5

The height of the storage space is 6 feet. The length is 2 times the width. The volume of the storage is 48 cubic feet. What is the width and length of the storage space

Answers

Step-by-step explanation:

Let's use the formula for the volume of a rectangular prism, which is:

V = lwh

where V is the volume, l is the length, w is the width, and h is the height.

We are given that the height is 6 feet, and the volume is 48 cubic feet. Therefore, we can solve for the product of the length and width:

lw = V / h = 48 / 6 = 8

We are also given that the length is twice the width, so we can substitute 2w for l:

(2w)w = 8

Simplifying this equation, we get:

2w^2 = 8

Dividing both sides by 2, we get:

w^2 = 4

Taking the square root of both sides, we get:

w = 2

Therefore, the width of the storage space is 2 feet. Since the length is twice the width, the length is:

l = 2w = 2(2) = 4

So the length of the storage space is 4 feet.

Manuel the trainer has two solo workout plans that he offers his clients: plan a and plan b. each client does either one or the other (not both). on monday there were 3 clients who did plan a and 8 who did plan b. manuel trained his monday clients for a total of 7 hours and his tuesday clients for a total of 6 hours. how long does each workout plans last?​

Answers

Plan a lasts 1/5 of an hour (or 12 minutes) and plan b lasts 29/5 hours (or 5 hours and 48 minutes).

Let's denote the length of plan a by 'a' and the length of plan b by 'b' (measured in hours).

From the problem, we know that:

- On Monday, 3 clients did plan a and 8 clients did plan b. Therefore, the total time spent on plan a on Monday was 3a and the total time spent on plan b on Monday was 8b.

- On Tuesday, we don't know how many clients did each plan, but we do know that the total time spent on both plans was 6 hours.

Putting these together, we can create a system of two equations:

3a + 8b = 7  (total time spent on Monday)

a + b = 6    (total time spent on Tuesday)

We can solve this system by using substitution. Rearranging the second equation, we get:

b = 6 - a

Substituting this expression for b into the first equation, we get:

3a + 8(6 - a) = 7

Simplifying and solving for a, we get: a = 1/5

Substituting this value back into the expression for b, we get:

b = 6 - a = 29/5

Evie rolls a fair number cube with faces labeled 1 through 6. She selects a marble from a bag were 3 are green and 1 is red. Select which point on the number line correctly represents the probability she


will land on an even number and then selects a green marble

Answers

The point on the number line that represents the probability of rolling an even number and selecting a green marble is 3/8, which is between 0.3 and 0.4 on the number line.

Will she land on an even number and then selects agreen marble?

The probability of rolling an even number is 3/6, which can be simplified to 1/2, because there are three even numbers (2, 4, and 6) out of six possible outcomes.

The probability of selecting a green marble from the bag is 3/4, because there are three green marbles out of four total marbles in the bag.

To calculate the probability of both events happening together (rolling an even number and selecting a green marble), you multiply the probabilities of each event:

P(even number and green marble) = P(even number) x P(green marble)

P(even number and green marble) = (1/2) x (3/4)

P(even number and green marble) = 3/8

A cuboid has a volume of 1815 cm³. Each side of the cuboid is a whole number of centimetres and each side is longer than 1 cm. Find all the possible dimensions of the cuboid

Answers

There are 4 possible sets of dimensions for the cuboid with a volume of 1815 cm³.

How to solve for the dimensions

First, find the prime factors of 1815:

1815 = 3 × 5 × 11 × 11

Now, we need to find all possible combinations of these factors into three whole numbers. Each combination of three numbers, when multiplied, should give 1815. We can do this by finding the different ways the prime factors can be distributed among the three dimensions:

3 × 5 × (11 × 11) = 15 × 121 (height × width × length)

3 × 11 × (5 × 11) = 33 × 55

5 × 11 × (3 × 11) = 55 × 33

11 × 11 × (3 × 5) = 121 × 15

We have found 4 different sets of dimensions for the cuboid:

15 × 121 × 1

33 × 55 × 1

55 × 33 × 1

121 × 15 × 1

There are 4 possible sets of dimensions for the cuboid with a volume of 1815 cm³.

Suppose that a random sample of 100 smokers



reveals that the average weight gain after quitting



smoking was 20 pounds with a standard deviation of 6



pounds.



The value of xis



A. 6.



B. 20.



C. 100.



D. 6/V100 = 0. 6.

Answers

The value of x, which is  the sample mean and represents the average weight gain after quitting smoking, is 20. Therefore, the correct option is B.

Given that the random sample of 100 smokers reveals an average weight gain of 20 pounds after quitting smoking and a standard deviation of 6 pounds, the value of x is determined as follows.

1. Random sample of 100 smokers (n = 100)

2. Average weight gain after quitting smoking is 20 pounds (mean, x' = 20)

3. Standard deviation is 6 pounds (σ = 6)

Option A (6) is incorrect because it does not relate to the given information.

Option C (100) is also incorrect because it refers to the sample size, which is not relevant to finding the value of x.

Option D (6/√100 = 0.6) is incorrect because it calculates the standard error of the mean, which is not what the question is asking for.

Therefore, the correct answer is option B: 20, which is the sample mean and represents the average weight gain after quitting smoking.

months.

Answers

human hair to grow 20 inches, considering the length of hair is proportional to the number of months it has grown.

First, let's establish the proportionality constant, which is the average rate at which human hair grows. On average, human hair grows approximately 0.5 inches per month.

Now, let's find out how many months it takes for hair to grow 20 inches. We can set up a proportion equation as follows:

Length of hair (in inches) / Number of months = Proportionality constant
Let "x" be the number of months it takes for hair to grow 20 inches. We can write the equation as:
20 inches / x months = 0.5 inches/month

To solve for x, we can multiply both sides by x months, which gives us:
20 inches = 0.5 inches/month * x months
Now, we can divide both sides by 0.5 inches/month:

x months = 20 inches / 0.5 inches/month
x months = 40 months

So, it takes 40 months for human hair to grow 20 inches, considering the length of hair is proportional to the number of months it has grown.

How would you classify this system of equations? 3x + 2y = –2 and

6x + 4y = 15

Answers

The system of equations 3x + 2y = –2 and 6x + 4y = 15 can be classified as inconsistent systems.

To classify the given system of equations, we will analyze the coefficients of the variables and constants to determine if the equations are dependent, independent, or inconsistent. The system is:

1) 3x + 2y = -2
2) 6x + 4y = 15

First, let's check if the equations are multiples of each other. If we multiply the first equation by 2, we get:

1') 6x + 4y = -4

Comparing equation 1' with equation 2, we can see that the left-hand sides are equal, but the right-hand sides are different (-4 ≠ 15). Therefore, the equations are not multiples of each other.

Next, we'll examine the coefficients of x and y. In both equations, the ratio of the coefficients of x to y is the same (3/2 and 6/4). This means the lines represented by these equations are parallel.

Since the lines are parallel and not multiples of each other, they do not intersect, meaning there is no common solution for this system of equations. Therefore, we can classify this system as inconsistent system.

5) If the price charged for a bolt is p cents, then x thousand bolts will be sold in a certain hardware store, where p = 82 - x 26 . How many bolts must be sold to maximize revenue?

Answers

To maximize the revenue, we need to find the maximum value of the revenue function.

The revenue function, R(x), is given by the product of the price per bolt (p) and the number of bolts sold (x thousand), which is R(x) = p * x.

Given the price function p = 82 - 26x,

we can substitute this into the revenue function:

R(x) = (82 - 26x) * x

Now, we need to find the maximum value of R(x). We'll do this by taking the derivative of R(x) with respect to x and setting it to zero:

R'(x) = d/dx[(82 - 26x) * x] R'(x) = 82 - 52x

Now, we set R'(x) = 0 and solve for x: 0 = 82 - 52x 52x = 82 x = 82 / 52 x ≈ 1.58

So, approximately 1.58 thousand (or 1580) bolts must be sold to maximize revenue in the hardware store.

Answers

The area of the sign can be calculated by finding the area of the trapezoid shape. The formula for the area of a trapezoid is A = (1/2) * (base1 + base2) * height. In this case, the bases are 5.5 feet (half of 11 feet, which is the flat top of the five-sided figure) and 9 feet (the entire length of the image), and the height is 4 feet. Plugging these values into the formula, we get:

A = (1/2) * (5.5 + 9) * 4

A = (1/2) * 14.5 * 4

A = 7.25 * 4

A = 29

So, the area of the sign is 29 square feet.

The volume of a rectangular prism is calculated by multiplying its length, width, and height. In this case, the length is given as 71.5 inches, the width is given as 60 inches, and the volume is given as 43,972.5 in^3. We can solve for the height by dividing the volume by the product of the length and width:

Height = Volume / (Length * Width)

Height = 43,972.5 / (71.5 * 60)

Height ≈ 10.25 inches

So, the height needed to reach the desired volume is approximately 10.25 inches.

The area of the rectangular box face can be calculated by finding the length of the sides of the rectangle using the given coordinates, and then using the formula for the area of a rectangle, which is A = length * width. In this case, the length is the difference between the x-coordinates of the two points on the x-axis (4 - (-8) = 12) and the width is the difference between the y-coordinates of the two points on the y-axis (4 - (-2) = 6). Plugging these values into the formula, we get:

A = 12 * 6

A = 72

So, the area of the label needed to cover the face of the box is 72 square inches.

The perimeter of a rectangle is calculated by adding the lengths of all four sides. In this case, we can use the given coordinates of the four points to find the lengths of the sides. The length is the difference between the x-coordinates of the two points on the x-axis (3 - (-2) = 5) and the width is the difference between the y-coordinates of the two points on the y-axis (6 - (-3) = 9). Since the opposite sides of a rectangle have equal lengths, the perimeter is twice the sum of the length and width:

Perimeter = 2 * (Length + Width)

Perimeter = 2 * (5 + 9)

Perimeter = 2 * 14

Perimeter = 28

So, the perimeter of the rectangle created by the points is 28 units.

The volume of a rectangular prism is calculated by multiplying its length, width, and height. In this case, the length is given as 14.2 yards (14 and one-fifth yards), the width is given as 7 yards, and the height is given as 8 yards. Plugging these values into the formula, we get:

Volume = Length * Width * Height

Volume = 14.2 * 7 * 8

Volume ≈ 795.2

So, the volume of the rectangular prism is approximately 795.2 cubic yards. Answer: seven hundred ninety-five and one-fifth yd3
