Use the following formula to find the answer to this question:

S * Q + M * Q = P

Representations:

S = The amount of points for short-answer questions.

M = The amount of points for multiple-choice questions.

Q = Number of questions for each of the type of questions that add up to the total number of questions on the test (20 questions).

P = Total points on the test.

Since there is a total of 50 points on the 20 question test, you would need to divide up the amount of questions there are for each of the type there are on the test, short-answer, and multiple-choice.

3 * Q + 1 * Q = P

Now find how many of the type of questions there are out of 20 questions on the test that would add up to the total number of points on the test.

3 * Q + 1 * Q = 50

(15 + 5 = 20 questions on the test, 15 and 5 can be used for the number of questions for each type of question on the test).

3 * 15 + 1 * 5 = 50

45 + 5 = 50

50 = 50

So, your total number of multiple choice questions are: 5.

And, your total number of short answer questions are: 15.

I would go with D. for your answer. I may be wrong.

Question

The figure is made up of a cylinder and a half sphere. What is the volume of the composite figure? Round to the nearest hundredth. radius: 4mm
cylinder length: 7mm

Solution 1

We know that

[volume of the composite figure]=volume of cylinder + volume hemisphere

volume cylinder=pi*r²*h

r=4 mm

h=7 mm

volume cylinder=pi*4²*7----> 351.68 mm³

volume of hemisphere=(4/6)*pi*r³

r=4 mm

volume of hemisphere=(4/6)*pi*4³----> 133.97 mm³

[volume of the composite figure]=351.68+133.97----> 485.65 mm³

[volume of the composite figure]=volume of cylinder + volume hemisphere

volume cylinder=pi*r²*h

r=4 mm

h=7 mm

volume cylinder=pi*4²*7----> 351.68 mm³

volume of hemisphere=(4/6)*pi*r³

r=4 mm

volume of hemisphere=(4/6)*pi*4³----> 133.97 mm³

[volume of the composite figure]=351.68+133.97----> 485.65 mm³

Solution 2

Answer:

Here’s the answer use it

485.65

Question

The height of a free falling object at time t can be found using the function, h(t) = - 12t2 + 36t. Where h(t) is the height in feet and t is the in seconds. Find the time when the object hits the ground

Solution 1

Given that height of the object can be found using the function h(t)=-12t²+36t, the time taken for the object to hit the ground is calculated as follows:

At the time the object hits the ground, height h(t)=0. Substituting this value in the equation we get:

0=-12t²+36t

solving for t we obtain.

12t²=36t

12t=36

hence

t=4

thus the time taken for the object to hit the ground is 4 seconds

At the time the object hits the ground, height h(t)=0. Substituting this value in the equation we get:

0=-12t²+36t

solving for t we obtain.

12t²=36t

12t=36

hence

t=4

thus the time taken for the object to hit the ground is 4 seconds

Question

THE FIRST ANSWER GETS A BRAINLIEST BUT THE ANSWER HAS TO BE RIGHT ALSO 20 POINTS Kiah plotted the locations of her home and the city of Huntingdon on the number line shown. Williamsburg is the same distance from Kiah’s home as Huntingdon, but it is in the opposite direction. Which statement best describes how to find the location of Williamsburg on the number line?
A) The opposite of 6.75 is −6.75, so Williamsburg is at −6.75.
B) The sum of 6.75 and 6.75 is 13.5, so Williamsburg is at 13.5.
C) The numbers 6.75 and −6.75 are the same, so Williamsburg is at 6.75.
D) Opposites, such as 6.75 and −6.75, sum to zero, so Williamsburg is at 0.

Question

The average price of a gallon of milk at 5 supermarkets is $3.52. The prices at 4 of the supermarkets are $3.39, $3.82, $3.61, and $3.44, respectively. What is the price at the fifth supermarket?

Solution 1

Adding all 5 prices together (substituting the fifth for x) and dividing by 5 (the total number of prices) gets us our equation. We know that this equals 3.52. So the cost of the fifth supermarkets milk is 3.17

Solution 2

Question

Identify the function in which Y varies directly with X

Solution 1

So I'm not entirely sure but I believe the answer is Y=5x, I think this is the answer because the variable y is dependent on x for it's value, if x=1 y=5(1) y=5. if x=4 y=5(4) y=20 all of the other problems have x dependent on y so I believe the answer is D. Y=5x

Question

Find (f o g)(2) and (f+g)(2) when f(x)=1/x and g(x)=4x+9

Solution 1

I think the answers are:

(f o g) (2) = 1/17 and (f+g) (2)= 17.5

(f o g) (2) = 1/17 and (f+g) (2)= 17.5

Question

Solve the following problem. Choose the correct answer. Sam's Discount Store offers a 2% discount for paying cash. How much would Joan pay if she pays cash for a set of skillets priced at $38.95? She would pay $ .

Solution 1

**Answer:**

**She would pay $38.17 in cash.**

**Step-by-step explanation:**

Sam's Discount store offers a 2% discount for paying cash.

Joan purchased a set of skillets costs = $38.95

She pays cash for it and got discount of 2%.

Lets calculate 2% of $38.95

= × 38.95

= 0.02 × 38.95 = $0.779

She would pay 38.95 - 0.779 =** $38.17**

Solution 2

If you multiply 38.95 by 0.02, you will get the amount taken away from the total when the discount is applied:38.95x0.02=0.78

Then, you subtract that discount price from the total to get the amount Joan pays when she pays with cash:38.95-0.78=38.17

Joan pays $38.17 in cash.

Then, you subtract that discount price from the total to get the amount Joan pays when she pays with cash:38.95-0.78=38.17

Joan pays $38.17 in cash.
