Question

energy output \div energy input = energy efficiency\
energy efficiency \times 100 = energy efficiency%\
energy output = 35 units\
energy input = 100 units\
what is the energy efficiency percentage?\
1%\
100%\
35%

Explanation:

Step1: Calculate Energy Efficiency

Using the formula \( \text{Energy Efficiency} = \frac{\text{Energy Output}}{\text{Energy Input}} \), substitute Energy Output = 35 units and Energy Input = 100 units.
\( \text{Energy Efficiency} = \frac{35}{100} = 0.35 \)

Step2: Convert to Percentage

Multiply the energy efficiency by 100 to get the percentage: \( 0.35 \times 100 = 35\% \)

Answer:

35% (the option with "35%")
