question 8 2 pts
if an engine is rated at 65 hp max, what hp is developed at 65% power? (nearest whole number)

Explanation:

Step1: Convert percentage to decimal

For the first question, convert 70% to decimal: $70\%=0.7$. For the second question, convert 65% to decimal: $65\% = 0.65$.

Step2: Calculate the developed power

For the first question, multiply the maximum - rated power by the decimal form of the percentage. The maximum - rated power is 200 hp, so the developed power is $200\times0.7 = 140$ hp.
For the second question, the maximum - rated power is 65 hp, so the developed power is $65\times0.65=42.25\approx42$ hp.

Answer:

Question 7: 140
Question 8: 42
