Answer :
Final answer:
To convert 20ºC to Fahrenheit, multiply by 9/5 and add 32, resulting in 68ºF. The correct answer is D. 68 degrees.
Explanation:
To find out what the temperature is on the Fahrenheit scale when it is 20ºC, you would use the given formula F = (9/5 • C) + 32. First, multiply the Celsius temperature by 9/5, and then add 32 to the result. Let's calculate:
F = (9/5 • 20) + 32
F = 36 + 32
F = 68
Therefore, when the temperature is 20ºC, it is 68ºF on the Fahrenheit scale. The correct answer is D. 68 degrees.
