Answer:
The cost of 1 gallon is $2.5
<em></em>
Step-by-step explanation:
Given
Cost of 14 gallons = $35
Required
Determine the cost of 1 gallon
From the given parameters, we have:

Divide both sides by 14



Hence,
<em>The cost of 1 gallon is $2.5</em>
The volume of a cylinder is
V=hpr^2 in this case h=40, r=20/2=10, and we will approximate pi as 3.14 so:
V=40(3.14)(10^2)
V=12560 ft^3
Answer:
using the given points substitute it into the equation y=mx+c
therefore
y=4
m=-2/3
X=6
c=?
so we should c=intercept
Step-by-step explanation:
y=mx+c
4=-2/3(6)+c
4=-4+c
c=4+4=8
therefore equation of the graph is y=-2/3X+8
Answer:
3.025 = 3.03
Step-by-step explanation:
A = (3.14)(r)(r)
28.74/3.14 = 9.152866
3.025 = r
