Answer :
Final answer:
Normal room temperature of 77 degrees Fahrenheit is equivalent to 25 degrees Celsius, which is choice A.
Explanation:
The student has asked what the normal room temperature of 77 degrees Fahrenheit is in degrees Celsius. The formula to convert Fahrenheit to Celsius is (F - 32) × 5/9. Using this formula, we calculate (77 - 32) × 5/9, which equals 25 degrees Celsius. So, the normal room temperature in Celsius is 25 degrees Celsius, corresponding to choice A.
The normal room temperature of 77 degrees Fahrenheit is equal to 25 degrees Celsius, using the conversion formula C = (F - 32) / 1.8. Option A, 25 degrees Celsius, is the correct answer.
To convert room temperature from degrees Fahrenheit to degrees Celsius, we can use the temperature conversion formula: Celsius (C) = (Fahrenheit (F) - 32) \/ 1.8. If the normal room temperature is 77 degrees Fahrenheit, we can plug this into the formula as follows:
C = (77 - 32) / 1.8
C = 45 \/ 1.8
C = 25
Therefore, the normal room temperature of 77 degrees Fahrenheit is equal to 25 degrees Celsius. This corresponds to option A. 25 degrees Celsius.
