I believe the correct answer is the last option D.

Explanation:

The volume is 2 1/4 because 1 1/2 times 1 1/2 times 1 = 2 1/4
The instructions then say that there is 8 half unit cubes for every one unit cube so you multiply 2 1/4 by 8 to get 18

Which equation has a constant of proportionality equal to 7?
A. 4y = 28x
B. 7y = 28x
C. 28y = 4x
D. 28y = 7x

Answers

A is correct.

Reasoning: 4 x 7 = 28

good luck!

The solution is Option A.

The equation which has a constant of proportionality k = 7 is 4y = 28x

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the equation be represented as A

Now , the value of A is

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

Now , the equation is

4y = 28x

On simplifying the equation , we get

Divide by 4 on both sides of the equation , we get

y = 28x/4

y = 7x

y = 7x is of the form y = kx where the value of k is 7

Therefore, the value of k is 7

Hence , the value of proportionality constant is 7

Regina travels ½ of a kilometer for every ¼ of a minute she drives. You were told that the trip from Times Square to Pelham Parkway is 72 kilometers. How many minutes would her trip have taken by car?

Answers

Answer:

36 minutes.

Step-by-step explanation:

The best way to solve this is to find how much distance is traveled in a minute and then divide the total distance by the distance traveled in a minute. Now let's apply.

1/4 x 4 = 1 minute, so in this problem, 1/2 x 4 = 1 minute.

1/2 x 4 = 2.

72 / 2 = 36.

Her trip would have taken 36 minutes by car.

Answer:

36 minutes.

Step-by-step explanation:

For every mile she takes it's 1/2 of a minute. Then just do 72/2 and get 36 :)

I have a triangle: Angle A = 3x +28; Angle B = 5x +52; Angle C = 2x - 10: Solve for X

Answers

I have no clue if I even did this right but here’s my work. I don’t wanna get it wrong for you!

Answer: x=11

Explanation: The anglers in a triangle must all add to 180.

Therefore, we can use the equation 180=3x+28+5x+52+2x-10

Combing like terms gives us 180=10x+70

Solving for x gives us 11.

To check our work, we can plug in 11 for x.

3(11)+28+5(11)+52+2(11)-10=180.

Hip hop music makes up 75% of Landon's music library. If he has downloaded 120 hip hop songs, how many songs does Landon have in his music library? (Explain your answer/show your work)

Answers

Answer: 160 songs.

Step-by-step explanation:

75% hip hop music - 120 songs

100% all music - x songs

Let's write the proportion:

[tex]\dfrac{120}{75} =\dfrac{x}{100} \\\\75x=120 \cdot 100\\75x=12000\\75x : 75 = 12000 : 75\\x = 160[/tex]

Thus, Landon have 160 songs in his music library.
