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 developed power for first question

Multiply the maximum - rated power by the decimal of the percentage. For the first question, with a maximum - rated power of 200 hp and 70% power, the developed power $P_1=200\times0.7 = 140$ hp.

Step3: Calculate developed power for second question

For the second question, with a maximum - rated power of 65 hp and 65% power, the developed power $P_2=65\times0.65=42.25\approx42$ hp.

Answer:

Question 1: 140
Question 2: 42
