On a cold winter day, the temperature is -10.0º C. What is the reading on the Fahrenheit scale?

A. 10.0 oF
B. 12.0 oF
C. 13.0 oF
D. 14.0 oF

I say A

F(C) = 9/5 C + 32

F(-10) = -18+32 = 14 (D)

what method did you use to get 10F?

To convert temperature from Celsius to Fahrenheit, you can use the formula:

°F = (°C * 9/5) + 32

In this case, the temperature is -10.0°C. Substituting this value into the formula, we get:
°F = (-10.0 * 9/5) + 32
°F = (-18.0) + 32
°F = 14.0

Therefore, the correct answer is D. 14.0 oF.
