Question

In order to evaluate energy demand for heating services, the number of heating degree days are calculated. The number of heating degree days can be calculated by the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day. If the high temperature for a day was 54°F and the low temperature for the same day was 46°F, what is the number of heating degree days?
15
115
50
11

Answer 1

Answer:

15

Step-by-step explanation:

T is the average of the high and low temperatures for the day.

Calculate the average for the two temperatures

Average = $\frac{54 + 46}{2}$ = $\frac{100}{2}$ = 50°F

Average = 50°F

T = 50°F

H = 65 - T

H = 65 - 50

H = 15
