75) y=mx+b. plug in slope and point
2=(3/2)(1)+b
2=(3/2)+b. solve for b
b=1/2. plug back into original question
y=(3/2)x+(1/2) multiply by 2 to get rid of fraction
(y=(3/2)x+(1/2))*2.
2y=3x+1. subtract over the 3x
-3x+2y=1
Same would be done with the other 4 problems.
Answer:
12 hr. mowing lawns
28 hr. working at Mc Donalds
Step-by-step explanation:
Let t = time mowing lawns
then 40 - t = time working at McDonalds
7,5(40 - t) + 6t = 282
300 - 7.5t + 6t = 282
-1.5t = -18
t = 12 hr. mowing lawns
40 - t = 40 - 12 = 28 hr. working at Mc Donalds

Answer:
Part a) The equation for the volume of the film canister is
Part b) The radius of the film canister is
Step-by-step explanation:
<u><em>The complete question is</em></u>
A film canister in the shape of a cylinder has a height of 8 centimeters and a volume of 32π cubic centimeters.
a. Write an equation for the volume of the film canister.
b. What is the radius of the film canister?
Part a) Write an equation for the volume of the film canister
we know that
The volume of a cylinder is equal to
where
r is the radius of the circular base
h is the height of the cylinder
we have
substitute
----> equation for the volume of the film canister
Part b) What is the radius of the film canister?
we have
Simplify
Divide by 8π both sides
square root both sides
