Answer: Choice A
The volume expression is 4/3 times pi times (3x)^3
===================================================
The volume of a sphere is found through the formula
V = (4/3)*pi*r^3
so we start with the fraction 4/3, multiply it with pi, and then multiply it with r^3
In this case, the radius is r = 3x because this is half of the diameter d = 6x
We simply replace the r with 3x in that formula above
V = (4/3)*pi*r^3
V = (4/3)*pi*( r )^3
V = (4/3)*pi*(3x)^3 ... replace r with 3x

Answer:
c. $20.23
Step-by-step explanation:
The overhead cost per labor hour is found by dividing overhead costs by labor hours:
$163,900/(8100 h) = $20.23 /h
The factory overhead rate is $20.23 per labor hour.

Step-by-step explanation:
Answer:
k = 3 1/5
Step-by-step explanation:
We want to isolate k, or move all numbers to the other side.
1/2 (4 - k) = 2/5
(4 - k) = 2/5 * 2
-k = 4/5 - 4
k = 4 - 4/5
k = 3 1/5
