so, one orange weighs 5 ounces.

All three methods give the same solutions. So, the cost of a chocolate truffle is (4C1 - C2) / 18 and the cost of a caramel turtle candy is (9C1 - 20C2).

An equation is a mathematical statement that shows the equality between two expressions. It consists of an equal sign between two expressions, which are usually separated by variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division.

Here,

Let x be the cost of a chocolate truffle and y be the cost of a caramel turtle candy. From the given information, we can write the following system of equations:

5x + 2y = C1 (Cost of Chocolate Lovers Bag)

2x + 8y = C2 (Cost of Combusting Caramel Bag)

To solve the system of equations, we can use various strategies. Here are a few:

Method 1: Substitution

We can solve for x or y in one equation and substitute the result into the other equation to eliminate one variable. For example, we can solve for x in the first equation:

5x + 2y = C1

5x = C1 - 2y

x = (C1 - 2y) / 5

Substituting this into the second equation:

2((C1 - 2y) / 5) + 8y = C2

Simplifying and solving for y:

C1/5 - 4y/5 + 8y = C2

y = (5C2 - C1) / 26

Substituting this value of y into the first equation and solving for x:

5x + 2((5C2 - C1) / 26) = C1

x = (3C1 - 10C2) / 65

Therefore, the cost of a chocolate truffle is (3C1 - 10C2) / 65 and the cost of a caramel turtle candy is (5C2 - C1) / 26.

Method 2: Elimination

We can multiply the first equation by 4 and the second equation by -1, and add them to eliminate y:

20x + 8y = 4C1

-2x - 8y = -C2

Adding these equations gives:

18x = 4C1 - C2

x = (4C1 - C2) / 18

Substituting this into the first equation and solving for y:

5((4C1 - C2) / 18) + 2y = C1

y = (9C1 - 20C2) / 36

Therefore, the cost of a chocolate truffle is (4C1 - C2) / 18 and the cost of a caramel turtle candy is (9C1 - 20C2) / 36.

Method 3: Matrix algebra

We can write the system of equations in matrix form:

[5 2] [x] [C1]

[2 8] [y] = [C2]

Using matrix algebra, we can solve for the variables:

[x] [C1] [8 -2] [y]

[y] = [C2] [-2 5 ] [x]

Multiplying the matrices, we get:

[x] [8x - 2y] [C1]

[y] = [-2x + 5y] * [C2]

Solving for x and y:

x = (4C1 - C2) / 18

y = (9C1 - 20C2) / 36

Therefore, the cost of a chocolate truffle is (4C1 - C2) / 18 and the cost of a caramel turtle candy is (9C1 - 20C2) / 36.

According to the given information, the absolute value is |x - 7/6| = 5/6.

What is an algebraic expression?

A mathematical expression known as an algebraic expression can include variables, integers, and mathematical operations including addition, subtraction, multiplication, and division.

When expressing quantities or values that might change depending on the values given to the expression's variables, algebraic expressions are utilised. Expressions in algebra can include one or more variables and be simple or complex.

Two solutions x=1/2, x=-1/3

|x - 7/6| = 5/6.

We know that the absolute value of (1/2 - 7/6) equals the absolute value of (-1/3 - 7/6) because they are opposites and have the same absolute value. So we need an expression that equals 5/6 when either 1/2 - 7/6 or -1/3 - 7/6 is plugged in for x.

To get an expression that equals 5/6 when 1/2 - 7/6 is plugged in for x, we can subtract 7/6 from 1/2 and take the absolute value of the result:

|1/2 - 7/6| = |-1/6| = 1/6.

To get an expression that equals 5/6 when -1/3 - 7/6 is plugged in for x, we can subtract 7/6 from -1/3 and take the absolute value of the result:

|-1/3 - 7/6| = |-9/6| = 3/2.

Since both expressions have the same absolute value of 5/6, we can use either one as the absolute value expression in the equation. Thus,

|x - 7/6| = 5/6.

The probability of selecting a striped marble, not replacing it, then selecting a black marble is 4/15.

The probability of selecting a striped marble on the first draw is 6/10, since there are 6 striped marbles out of a total of 10 marbles in the bag.

After the first marble is drawn, it is not replaced, so there are now 9 marbles left in the bag. Out of these, there are 4 solid marbles and 5 striped marbles. Therefore, the probability of selecting a black marble on the second draw is 4/9.

To find the probability of both of these events occurring together, we multiply the probabilities

P(striped, then black) = P(striped) × P(black | striped not replaced)

P(striped, then black) = (6/10) × (4/9)

P(striped, then black) = 24/90

Joni is not correct because she used the simple interest rate formula, not the compound interest rate formula. She will have $231.53.

A loan or investment's principle amount is the sole amount used to compute simple interest. Any interest that has been earned on interest that has accrued over time is not taken into account by simple interest.

Contrarily, compound interest is a sort of interest that takes into account both the original principal and any interest that has accrued over time. As a result, the interest gained during one period is added to the principle for the following month, where it continues to earn interest.

Joni is not correct, because $230 is just the interest she will earn; she will have $430 total.

The compound interest is given by the formula:

[tex]A = P (1 + r/n)^{(nt)}[/tex]

Substituting the values we have:

[tex]A = 200(1 + 0.05/1)^{(1*3)}\\A = 200(1.05)^3[/tex]

A = 200(1.157625)

Rewrite the equation: 4*4+3-5

Multiply: 16+3-5

Add: 19-5

Subtract: 14

the measure of angle V is approximately 21.87 degrees. To find the measure of angle V, we need to use the fact that the sum of the angles in a triangle is 180 degrees. Therefore, we can write:

m∠V + m∠W + m∠X = 180

where angle X is the third angle in the triangle formed by V, W, and X. We know that m∠W is (3x+4) degrees, and we can see that angle X is adjacent to angle V, so we can use the fact that the sum of adjacent angles is equal to the total angle to write:

m∠V + m∠X = (2x+2) degrees

Now we can substitute this expression for m∠X into the first equation to eliminate m∠X:

m∠V + (2x+2 - m∠V) + (3x+4) = 180

Simplifying and solving for x, we get:

5x + 6 = 180

5x = 174

x = 34.8

Now we can substitute this value of x back into our expression for m∠V + m∠X to find m∠V:

m∠V + (2(34.8)+2 - m∠V) = 71.6

Simplifying and solving for m∠V, we get:

3m∠V = 65.6

m∠V = 21.87 (rounded to two decimal places)

Therefore, the measure of angle V is approximately 21.87 degrees.

Answer:

To graph the function f(x) = 2sin(x) - 2 by hand, we can use the following steps:

Step 1: Find the amplitude

The amplitude of the function is the absolute value of the coefficient of the sine function, which is 2 in this case. Therefore, the amplitude is 2.

Step 2: Find the period

The period of the function is given by the formula 2π/b, where b is the coefficient of x in the sine function. In this case, b = 1, so the period is 2π/1 = 2π.

Step 3: Find the midline

The midline is the horizontal line that the graph oscillates around. For the sine function, the midline is the y-value of the function when there is no vertical shift. In this case, the midline is y = -2.

Step 4: Find the y-intercept

The y-intercept is the value of the function when x = 0. Plugging in x = 0, we get f(0) = 2sin(0) - 2 = -2. Therefore, the y-intercept is -2.

Step 5: Sketch the graph

Based on the amplitude, period, midline, and y-intercept we just found, we can sketch the graph of the function as follows:

- The graph oscillates between y = 2 and y = -6, with a midline at y = -2.

- The graph starts at (0, -2), then goes up to (π/2, 0), down to (π, -2), down further to (3π/2, -4), and back up to (2π, -2).

- The graph is symmetric about the midline.

Therefore, the information about the function is:

Amplitude: 2 (The distance from the midline to the maximum or minimum of the graph is 2.)

Period: 2π (The graph completes one full cycle over a horizontal distance of 2π.)

Midline: y = -2 (The horizontal line that the graph oscillates around.)

y-intercept: -2 (The value of the function when x = 0.)

Given the rectangle's dimensions, its area is 12 cm² and the circle's area is π cm². Thus, the shaded region's area is about 8.57 cm².

The area of the shaded region is equal to the area of the rectangle minus the area of the circle.

The area of the rectangle is given by:

Area of rectangle = length x width = 4 cm x 3 cm = 12 cm²

The area of the circle is given by:

Area of circle = π x radius² = π x (1 cm)² = π cm²

Therefore, the area of the shaded region is:

Area of shaded region = Area of rectangle - Area of circle

Area of shaded region = 12 cm² - π cm²

Area of shaded region ≈ 8.57 cm² (rounded to the nearest hundredth)

The coordinates of point C are (17, -1).

let say a line have two points A (x1,y1) and B(x2,y2)

slope of line AB = (y2 - y1) / (x2 - x1)

Now given that  points B, C, and D are collinear, then they lie on the same straight line. This means that the slope of the line passing through any two of the points will be the same as the slope of the line passing through the other two points. We can use this fact to find the value of x.

The slope which is between points B and C is:

slope of line BC = (y2 - y1) / (x2 - x1) = (-1 - 7) / (x - (-1)) = -8 / (x + 1)

The slope which is between points C and D is:

slope of line CD = (y2 - y1) / (x2 - x1) = (8 - (-1)) / (1 - x) = (9) / (1 - x)

Since B, C, and D are collinear, slope of BC = slope of CD. Therefore:

-8/(x+1) = 9/(1-x)

by solving the x, we get:

-8(1 - x) = 9(x + 1)

-8+8x=9x + 9

x = 17

Solving for x, we have:

x = 50 milligrams

So, Yosef drank 50 milligrams of vitamin C.

To find the percent of the daily recommended amount of vitamin C this represents, we can use another proportion:

80 milligrams     100%

50 milligrams      x%

Solving for x, we have:

x = (50/80) * 100 ≈ 62.5%

Therefore, Yosef drank orange juice containing 62.5% of the daily recommended amount of vitamin C.

To model the given data points, we can use a linear function of the form y = mx + b.

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

m = (-6 - (-2)) / (1 - 0)

m = -4/1

m = -4

Now, we can use the slope and one of the points to find the y-intercept (b):

The circumference is calculated using the formula C = 2πr, where C is the circumference, r is the radius of the circle, and π (pi) is a mathematical constant approximately equal to 3.14159. The circumference is measured in units of length, such as meters or feet.

by the question.

To solve this problem, we need to first find the circumference of each wheel:

[tex]Circumference of Nguyon's lorry wheel = 2πr = 2 x (22/7) x 28 cm = 176[/tex]cm

Circumference of Kathel's car wheel = πd = (22/7) x 42 cm = 132 cm

Next, we can calculate how many revolutions each wheel needs to make to cover a distance of 770 m:

Number of revolutions for Nguyon's lorry wheel = distance ÷ distance covered in one revolution

= 77000 cm ÷ 176 cm ≈ 437.5 revolutions

Number of revolutions for Kathel's car wheel = distance ÷ distance covered in one revolution

= 77000 cm ÷ 132 cm ≈ 583.3 revolutions

Finally, we can find the difference in revolutions between the two wheels:

Difference in revolutions = Number of revolutions for Kathel's car wheel - Number of revolutions for Nguyon's lorry wheel

Answer:

$104.11

Step-by-step explanation:

To calculate the monthly payment for a loan, we can use the following formula:

Monthly payment = (Pr(1+r)^n) / ((1+r)^n-1)

where:

P = the principal amount (the amount borrowed)

r = the monthly interest rate (annual interest rate divided by 12)

n = the number of payments (total number of years multiplied by 12)

In this case, the principal amount is $3825, the annual interest rate is 15%, and the loan term is 4 years. So we have:

P = $3825

r = 0.15/12 = 0.0125

n = 4*12 = 48

Substituting these values into the formula, we get:

Monthly payment = (38250.0125(1+0.0125)^48) / ((1+0.0125)^48-1)

Monthly payment ≈ $104.11

Therefore, the monthly payment for a $3825 loan at 15% annual interest for 4 years is approximately $104.11.
