Weight of man and paint = 160 + 5 = 165 total pounds.
Gravitational force is independent of the path taken so we can ignore the radius of the silo.
Work done = total weight x height
The problem says he climbs to the top so overall height is 90 feet
Work = 165 lbs x 90 ft = 14,850 ft-lbs

Answer:
Step-by-step explanation:
Remark
The total number of people he has surveyed is 12 + 64 = 76
So your probability is 12 / 76
When turned into a percent, the fraction becomes 100 times 12/76.
Givens
12 wore sneakers
64 wore other shoes
76 total in survey
Solution
P(sneakers) = # sneakers / Total
P(sneakers) = 12 / 76 = 0.15789
P(sneakers as a %) = 0.15789 * 100 = 15.789%
Answer
<em>P(sneakers %) = 15.8 rounded to nearest 1/10</em>
