An outside thermometer reads [tex]$57^{\circ} F$[/tex]. What is this temperature in [tex]^{\circ} C[/tex]? Round your answer to the nearest whole number.

A. 14
B. 49
C. 71
D. 135

Answer :

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

[tex]\[ C = (F - 32) \times \frac{5}{9} \][/tex]

where [tex]\( F \)[/tex] is the temperature in Fahrenheit and [tex]\( C \)[/tex] is the temperature in Celsius.

Let's use this formula to convert [tex]\( 57^\circ F \)[/tex] to Celsius:

1. Subtract 32 from the Fahrenheit temperature:

[tex]\[ 57 - 32 = 25 \][/tex]

2. Multiply the result by [tex]\(\frac{5}{9}\)[/tex]:

[tex]\[ 25 \times \frac{5}{9} \approx 13.89 \][/tex]

3. Round the Celsius temperature to the nearest whole number:

[tex]\[ 13.89 \][/tex] rounds to [tex]\( 14 \)[/tex]

So, [tex]\( 57^\circ F \)[/tex] is approximately equal to [tex]\( 14^\circ C \)[/tex]. The answer is 14.
