energy output = 25 units\nenergy input = 100 units\nif you want to calculate energy efficiency,\nwhat value should be substituted into the\ngreen box?\n? ÷ □ = energy efficiency\nenergy output ÷ energy input = energy efficiency\nhint: enter a number.
Answer
Explanation:
Step1: Recall efficiency formula
Energy Efficiency = $\frac{\text{Energy Output}}{\text{Energy Input}}$
Step2: Identify green box value
The green box is the numerator, so use the given energy output value.
Answer:
25
