The volume of a rectangular pyramid is 60. the width of the base is then scaled by a factor of 3, the length of the base is scaled by a factor of 5/ 2, and the height of the pyramid is scaled such that the resulting image has the samevo lume as the original pyramid. find the scale factor used for the height of the pyramid.

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
