This is the concept of volumes of solid materials. The volume of the cone is given by:
V=1/3*(base area)*height
making base area the subject we get:
(3V)/h=base area
But:
Volume= V
height=h units
Thus;
Base area=(3*V)/h=(3V)/h square units
Answer:
32 gallons of water
Step-by-step explanation:
8 minutes = 480 seconds.
set up a proportion:
1/15=x/480
we have to solve for x:
15x=480
x=32.
Jess uses 32 gallons of water.
We only should take 3,9 from 9,4....
And it will be 5,5 ... approximately 6

Its like process of elimination for me to be honest.
Answer: f(g(x))= -2x+43
Step-by-step explanation:
Here, you would start by substituting the equation for g(x) into the x value of f(x) equation.
Since g(x)=1/4x+5, f(g(x)) would be:
f(g(x))= 3-8(1/4x+5)
Then you would simplify.
f(g(x))= 3-8(1/4x+5)
= 3-2x+40
=-2x+43
