Answer:
27000 inches^3
Step-by-step explanation:
The volume of a cube is sidelength^3.
The side length is 30 inches, so the volume is 30^3 = 27000 inches^3.
36.
Convert 10% to .1, (10 divided by 100)
then multiply 40 times .1
then subtract 4 by 40
=36
Let y be x, and x be y.
x = 4y - 8
Rearrange to make y the subject.
x + 8 = 4y
Therefore
y = (x + 8) / 4
is the inverse.
