Answers

Answer 1

The magnitude of vector v is 4 and the direction is 125 degrees.

Given that vector u has a magnitude of 2 and a direction of 55 degrees, we can determine the magnitude and direction of vector v.

To find the magnitude of vector v, we can use the equation:

|v| = |-2u|

Since u has a magnitude of 2, we can substitute it into the equation:

|v| = |-2 * 2|

|v| = |-4|

|v| = 4

The magnitude of vector v is 4.

To find the direction of vector v, we can note that multiplying a vector by -1 (in this case, multiplying u by -2) reverses its direction. So the direction of v is the exact opposite of the direction of u.

Since the direction of u is 55 degrees, the direction of v is 55 degrees in the opposite direction. In the interval of 0 degrees ≤ θ < 360 degrees, the direction of v can be expressed as:

θ = 180 - 55

θ = 125 degrees

A trader made profit of 24percent by selling an article for GHC 3720.00.How much should he have sold it to make a profit of 48percent?

Answers

Therefore, the trader should sell the article for GHC 4440.00 to make a profit of 48%.

What is percent?

Percent is a way of expressing a number as a fraction of 100. The term "percent" means "per hundred". Percentages are usually denoted by the symbol %, which is placed after the numerical value. Percentages are used in many fields, including finance, science, and everyday life, to represent proportions, rates, and changes in quantities.

Here,

Let's call the original cost of the article "C".

We know that the trader made a profit of 24%, which means that he sold the article for 100% + 24% = 124% of its cost:

124% of C = GHC 3720.00

To find C, we can divide both sides by 1.24:

C = GHC 3720.00 / 1.24

C = GHC 3000.00

So the trader originally purchased the article for GHC 3000.00.

Now we want to know how much the trader should sell the article for to make a profit of 48%. This means that he wants to sell the article for 100% + 48% = 148% of its cost:

148% of C = ?

Substituting C = GHC 3000.00, we get:

148% of GHC 3000.00 = (148/100) x GHC 3000.00

= GHC 4440.00

Find the value(s) of the variable(s). if necessary, round decimal answers
to the nearest tenth.

Answers

To find the value(s) of the variable(s), you need to have an equation or problem statement that relates the variable(s) to other known quantities. Once you have this equation or statement, you can solve for the variable(s) by manipulating the equation algebraically.

For example, if the problem states that 2x + 5 = 17, you can solve for x by first subtracting 5 from both sides to get 2x = 12. Then, you can divide both sides by 2 to get x = 6. So, the value of the variable x is 6.

In some cases, you may need to use more advanced methods such as factoring or the quadratic formula to solve for the variable(s). Regardless of the method used, it's important to check your answer(s) by plugging them back into the original equation to make sure they satisfy the given conditions.

In terms of rounding decimal answers to the nearest tenth, this means that if the answer is a decimal with more than one digit after the decimal point, you would round to the nearest tenth place (i.e. the digit immediately to the right of the decimal point). For example, if the answer is 3.456, you would round to 3.5.

What is the cost of one apple?

Answers

The cost of apples and bananas are $ 0.70 and $ 1.10 respectively if Patricia bought 4 apples and 9 bananas for $12.70 and Jose got 8 apples and 11 bananas for $17.70

Let the cost of one apple be a

the cost of one banana be b

In the case of Patricia,

12.70 = cost of 4 apples + cost of 9 bananas

Cost of 4 apples = 4a

Cost of 9 bananas = 9b

The equation we get is

4a + 9b = 12.70 ----(i)

In the case of Jose,

17.70 = cost of 8 apples + cost of 11 bananas

Cost of 8 apples = 8a

Cost of 11 bananas = 11b

The equation we get is

8a + 11b = 17.70 ----(ii)

Multiply (i) by 2

8a + 18b = 25.40 --- (iii)

Subtract (ii) and (iii)

7b = 7.70

b = $ 1.10

4a + 9 (1.10) = 12.70

4a + 9.90 = 12.70

4a = 2.80

a = $ 0.70

a tennis player makes a successful first serve 60% of the time. assuming that each serve is independent of the others, if the player serves 8 times, what is the probability that she gets exactly 3 first serves in?

Answers

The probability that the tennis player will make exactly 3 first serves out of 8 attempts is 0.278%.

To solve this problem, we can use the binomial distribution. The binomial distribution is used to calculate the probability of a certain number of successes (in this case, first serves) in a fixed number of independent trials (in this case, serves). The formula for the binomial distribution is:

P(X = x) = (n choose x) x pˣ x (1 - p)ⁿ⁻ˣ

where P(X = x) is the probability of getting x successes, n is the number of trials, p is the probability of success in each trial, and (n choose x) is the binomial coefficient, which represents the number of ways to choose x successes out of n trials.

Using this formula, we can plug in the values from our problem:

P(X = 3) = (8 choose 3) x 0.6³ x (1 - 0.6)⁸⁻³

P(X = 3) = (8! / (3! x 5!)) x 0.216 x 0.32768

P(X = 3) = 0.278%

This means that out of 1000 attempts, we can expect the player to make exactly 3 first serves around 2-3 times. It's important to note that this is just an estimation, and the actual number of successful serves may vary.

Step-by-step explanation:

What is elimination method?

In the elimination method you either add or subtract the equations to get an equation in one variable

Lets solve for X first.

We have the equations:

5x+3y=8

4x+y=8

We take the GCM (3) and multiply everything on the bottom by -3 and multiply everything on the top by 1 (which in this case, dont touch the top) which we should now have:

5x+3y=8

-12x-3y=-36

We can now eliminate the Y and add like terms from the top to bottom, from which we should now have remaining:

-7x=-28

Solve for X

x=4

Now that we have 4, plug it in to one of the equations, which we should plug it in to 4x+y=12

4(4)+y=12

Simplify:

16+y=12

Subtract 16 to the other side:

Answers

According to given data GR(x) * GR(y) = 3 * 2m - 5

The given monomial is P(x;y) = -mx^3m-1 * y^2m-7, and it is known that GA(P) = 17.

We need to find the values of GR(x) and GR(y), which are the degrees of the monomial with respect to x and y, respectively.

Using the formula GA(P) = GR(x) + GR(y), we get GR(x) + GR(y) = 17.

Now, we can write the monomial as P(x;y) = (-m) * x^(3m-1) * y^(2m-7).

Therefore, GR(x) = 3m-1 and GR(y) = 2m-7.

Multiplying these two values, we get GR(x) * GR(y) = (3m-1) * (2m-7) = 6m^2 - 23m + 7.

Hence, the final answer is GR(x) * GR(y) = 6m^2 - 23m + 7.

Answers

68.2% confidence of the students drink between: 131 and 175 bottles of water per day.

Roll two fair dice. find p(a |b) where a stands from sum of the two faces is 10 and b stands for two dice are showing different faces. [a] (reduced fraction)

Answers

The probability in the two fair dice problem is given as [tex]P(A|B) = 1/6[/tex].

How to calculate probability in the two fair dice problem?

To find [tex]P(A|B)[/tex], we first need to find [tex]P(B)[/tex], which is the probability that two dice are showing different faces.

The total number of possible outcomes when rolling two dice is [tex]6x6 = 36[/tex]. Out of these [tex]36[/tex] possible outcomes, there are [tex]6[/tex] outcomes where both dice show the same face (e.g., both dice show a 1). Therefore, there are [tex]36-6=30[/tex] outcomes where two dice show different faces.

Hence, P(B) = [tex]30/36 = 5/6[/tex].

Next, we need to find the probability of A and B occurring together, i.e., P(A and B).

The possible pairs of faces that add up to 10 are [tex](4,6), (6,4),[/tex] and [tex](5,5)[/tex]. Each of these pairs can occur in 2 ways (e.g., the pair [tex](4,6)[/tex] can occur as [tex](4,6) or (6,4))[/tex]. Therefore, there are 6 ways in total for the sum of two dice to be 10.

Out of these 6 outcomes, only one outcome (the pair (5,5)) violates condition B (i.e., both dice showing the same face). Therefore, there are [tex]6-1=5[/tex] outcomes where the sum of the two dice is 10 and the two dice show different faces.

Hence, P(A and B) [tex]= 5/36[/tex].

Using the formula for conditional probability, we can find P(A|B) as:

[tex]P(A|B) = P(A and B) / P(B) = (5/36) / (5/6) = 1/6.[/tex]

Therefore, [tex]P(A|B) = 1/6[/tex], which is the required probability.

Find the area of the region bounded by the

The area of the region bounded by the curves is 4/3 square units.

To find the area of the region bounded by the curves y = 10 - [tex]x^2[/tex] and y = [tex]x^2[/tex] + 8, we need to find the points of intersection between the two curves.
Setting the two equations equal to each other, we have:
10 - [tex]x^2[/tex] = [tex]x^2[/tex] + 8
Simplifying, we get:
[tex]2x^2[/tex] = 2
[tex]x^2[/tex] = 1
x = ±1
Substituting x = 1 into either equation gives us:
y = 10 - [tex]1^2[/tex] = 9
And substituting x = -1 gives us:
y = 10 - [tex](-1)^2[/tex] = 10
So the two curves intersect at the points (1, 9) and (-1, 10).
To find the area of the region bounded by the curves, we need to integrate the difference between the two equations with respect to x, from x = -1 to x = 1:
∫[10 - [tex]x^2[/tex]] - [[tex]x^2[/tex] + 8] dx, from x = -1 to x = 1
= ∫(2 - 2[tex]x^2[/tex]) dx, from x = -1 to x = 1
= [2x - (2/3)[tex]x^3[/tex]] from x = -1 to x = 1
= 4/3
So

The area of the region bounded by the curves y = 10 - [tex]x^2[/tex] and y = [tex]x^2[/tex] + 8 is 4/3 square units.

If you need 2 1/4 cups of water for 1 cup of rice how much water do you need if you have 1/3 cup of rice?

Answers

The amount of water needed for 1/3 cup of rice, is 3/4 cups of water.

How much water is needed for 1/2 cup of rice?

The problem asks us to find out how much water is needed for 1/3 cup of rice, given that 2 1/4 cups of water are needed for 1 cup of rice. To solve this problem, we can use a proportion.

A proportion is an equation that says two ratios are equal. In this case, we want to set up a proportion that relates the amount of water needed to the amount of rice.

Let's start by writing down what we know. We know that for 1 cup of rice, we need 2 1/4 cups of water. We can write this as a ratio:

2 1/4 cups water : 1 cup rice

Now we want to figure out how much water we need for 1/3 cup of rice. Let's call the amount of water we need "x" (we don't know what it is yet), and set up another ratio:

x cups water : 1/3 cup rice

We can now set up our proportion by equating these two ratios:

2 1/4 cups water : 1 cup rice = x cups water : 1/3 cup rice

To solve for x, we can cross-multiply and simplify. Cross-multiplying means we multiply the numerator of one ratio by the denominator of the other ratio, like this:

(2 1/4 cups water) * (1/3 cup rice) = (x cups water) * (1 cup rice)

To simplify this, we can convert the mixed number 2 1/4 to an improper fraction:

2 1/4 = 9/4

Now we can substitute these values and multiply:

(9/4 cups water) * (1/3 cup rice) = (x cups water) * (1/1 cup rice)

Multiplying the fractions on the left-hand side gives:

9/12 cups water = (x cups water) * (1/1 cup rice)

Simplifying the fraction on the left-hand side gives:

3/4 cups water = x cups water

So we have found that x, the amount of water needed for 1/3 cup of rice, is 3/4 cups of water. Therefore, if you have 1/3 cup of rice, you would need to use 3/4 cups of water to cook it.

To find the fraction of the police dog's workday spent at the police station, we need to add up the fractions of time spent in each location and subtract them from 1, since the dog spends the rest of the day at the police station.

Fraction of time spent in police car =  [tex]1/3[/tex]

Fraction of time spent in public = [tex]1/2[/tex]

To add these fractions, we need to find a common denominator:

[tex]1/3 = 2/6\\1/2 = 3/6[/tex]

So, the fraction of the dog's day spent at the police station is:

[tex]1 - (2/6 + 3/6) = 1 - 5/6[/tex]

                        = [tex]1/6[/tex]

Therefore, the police dog spends 1/6 of its workday at the police station.

Find the measure of the missing angle
38°
X
Y

Answers

The measure of angle x is 77 degrees.

How to calculate the angle

We have two angles given: 65 degrees and 38 degrees. Let's call the measure of angle x as "x".

From the information, we have the measure of the missing angle of the angles in a triangle are 38°, 65° and x. Then we can set up an equation:

x + 65 + 38 = 180 (the sum of the measures of the angles in a triangle is 180)

Simplifying this equation, we get:

x + 103 = 180

x = 77

Therefore, the measure of angle x is 77 degrees.

A bag of marbles contains 5 red, 3 blue, and 12 yellow marbles. Predict the


number of times Hazel will select a blue marble out of 500 trials.

Answers

In a bag containing 5 red, 3 blue, and 12 yellow marbles, we will predict the number of times Hazel will select a blue marble out of 500 trials.

Step 1: Calculate the total number of marbles in the bag:
Total marbles = 5 red + 3 blue + 12 yellow = 20 marbles

Step 2: Determine the probability of selecting a blue marble:
Probability of selecting a blue marble = (number of blue marbles) / (total marbles) = 3 blue / 20 marbles = 3/20

Step 3: Predict the number of times Hazel will select a blue marble in 500 trials:
Predicted blue marbles selected = (probability of selecting a blue marble) x (total trials) = (3/20) x 500

Step 4: Perform the calculation:
(3/20) x 500 = 75

In conclusion, we predict that Hazel will select a blue marble 75 times out of 500 trials, given that the bag contains 5 red, 3 blue, and 12 yellow marbles.

Rewrite the following equation in slope-intercept form.

19x + 18y = –17

Answers

The given linear equation in slope intercept form is y = -19x/18 - 17/18.

What is the slope-intercept form?

In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;

y = mx + c

Where:

m represents the slope or rate of change.x and y are the points.c represents the y-intercept or initial value.

By making "y" the subject of formula, we have the following:

19x + 18y = –17

18y = -19x - 17

y = -19x/18 - 17/18

By comparison, we have the following:

Slope, m = -19/18.

y-intercept, c = -17/18.

The measure of the largest interior angle is  105°.

What is the measure of angle?

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Here, we have

Given: The measures of 5 of the interior angles of a hexagon are: 130, 120°, 80, 160, and 155. we have to find the measure of the largest interior angle.

The sum of all the six interior angles of a hexagon is 720°.

As sum of five angles is 130° + 120° + 80° + 160° +155° = 165°

The sixth angle is 720° - 165° = 75°

So the smallest interior angle of the hexagon is 75°.

and the largest exterior angle is 180° -  75° =  105°.

Hence, the measure of the largest interior angle is  105°.

Determine whether the given points represent the vertices of a trapezoid If so, determine whether it is isoscoles or not

A(-4,-1),B((-4,6),C(2,6),D(2,-4)

Answers

Answer:

It is a trapezoid

Step-by-step explanation:

Yes, the given points represent the vertices of a trapezoid.

A trapezoid is a quadrilateral with one set of parallel sides. In this case, the parallel sides are AB and CD. The other two sides, AD and BC, are not parallel.

The trapezoid is not isosceles because the two non-parallel sides are not congruent. AD has a length of 6 units, while BC has a length of 4 units.

Here is a diagram of the trapezoid:

A(-4,-1)

B((-4,6)

C(2,6)

D(2,-4)

A trapezoid is a quadrilateral with at least one pair of parallel sides. In this case, sides AB and CD are parallel because they have the same slope. So, the given points do represent the vertices of a trapezoid.

An isosceles trapezoid has two congruent legs (non-parallel sides). In this case, the length of side AD is `sqrt((-4-2)^2+(-1+4)^2)=sqrt(36+9)=sqrt(45)` and the length of side BC is `sqrt((-4-2)^2+(6-6)^2)=sqrt(36+0)=sqrt(36)`. Since `sqrt(45)` is not equal to `sqrt(36)`, the trapezoid is not isosceles.

To dilate a figure by a scale factor, we need to multiply the coordinates of each point by the scale factor. Given the scale factor K = 3, we can dilate the figure using the formula:

New x-coordinate = K * original x-coordinate

New y-coordinate = K * original y-coordinate

Let's apply this to the given coordinates:

(-1, 4)

New x-coordinate = 3 * (-1) = -3

New y-coordinate = 3 * 4 = 12
