X= total number of problems
This is a proportion problem. 80% is to 100% as 32 problems is to x problems.
80/100=32/x
Cross multiply
(80*x)=(100*32)
80x=3200
Divide both sides by 80
x=40
There were 40 questions on the test.
Hope this helps! :)

Answer:
4 + (2 + 1)2 = 4 + (3)2 = 4 + 9 = 13
1 ft = 12 in
6 in = 6/12 = 0.5 ft
9 in = 9/12 = 0.75 ft
D = M/V ⇒ M = DV
V = 0.5 * 0.5 * 0.75 = 0.1875 cubic foot
M = 41.7 * 0.1875 ≈ 7.8 pounds
Answer: B.
