Question

Convert 84 degrees Fahrenheit to Celsius and round the answer to the nearest tenth:

A. 28.9°C
B. 29.3°C
C. 29.4°C
D. 29.6°C

Answer 1

To convert 84 degrees Fahrenheit to Celsius, apply the formula C = 5/9 x (F - 32). The calculation gives you 28.89, which rounded to the nearest tenth is 28.9°C, corresponding to answer option A.

Step-by-step explanation:

To convert 84 degrees Fahrenheit to Celsius and round the answer to the nearest tenth, you use the formula C = 5/9 x (F - 32), where F is the Fahrenheit temperature and C is the Celsius equivalent.

Now let's calculate:

C = 5/9 x (84 - 32)

C = 5/9 x 52

C = 5 x 5.778

C = 28.89

When we round 28.89 to the nearest tenth, we get 28.9°C. So, the correct answer is A. 28.9°C.

The Celsius scale is also known as the centigrade scale because it is based on 100 degrees between the freezing point (0°C) and boiling point (100°C) of water at standard atmospheric pressure, with 'centi' meaning hundred.
