Which of the coordinate points below will fall on a line where the constant of proportionality is 1/4? Select all that apply. A)
kompoz [17]

Answer:

A) (4,1)  C) (12,3) D) (20,5)

Step-by-step explanation:

Required

Which has a constant of proportionality of 1/4

To solve this, we make use of:

y = kx

Where k is the constant of proportionality.

Solve for x

k = y/x

<u>Testing the given options</u>

A) (4,1)

k = y/x

k =1/4

B) (8,12)

k = y/x

k =12/8

k =3/2

C) (12,3)

k = y/x

k = 3/12

k = 1/4

D) (20,5)

k = y/x

k = 5/20

k = 1/4

E) (12,6)

k = y/x

k =6/12

k =1/2

A girl scout troop sold cookies. If the girls sold 5 more boxes the second week than they did the first, and if they doubled the
mihalych1998 [28]
We can let x be the number of boxes sold for the first week. We can as well express the number of boxes for the second and third week through x using the statements provided.

Since the girl scout sold 5 more boxes on the second week, we have (x + 5) number of boxes sold for the second week. Now, for the third week, since it's double that of the second week, we have 2(x + 5). Thus, we have the following:

first week: x
second week: x + 5
third week: 2(x + 5)

Given that the total number of boxes sold for the three weeks is 431. We have

x + (x + 5) + 2(x + 5) = 431
x + x + 5 + 2x + 10 = 431
4x + 15 = 431
4x = 431 - 15
4x = 416
x = 104

We have now the value of x. Using this, we can find the values for the second and third week.
x + 5 = `104 + 5 = 109
2(x + 5) = 2(109) = 218

Answer: 
first week: 104
second week: 109
third week: 218

A rectangular prism with a volume of 3 cubic units is filled with cubes with side lengths of 1/4 unit how many 1/4 unit cubes do
Julli [10]

Answer:

192 cubes

Step-by-step explanation:

So all we need to do is:

1) Find the area of 1 cube.

2) Divide the large prism volume with this.

SO 1)

the volume of cube = Length * width * height = (1/4)^3 = 1/64

SO 2)

the volume of prism / the volume of cube = 3/(1/64) = 192

Answer: 192 cubes
