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, we use the formula:

[tex]\[ \text{Celsius} = (\text{Fahrenheit} - 32) \times \frac{5}{9} \][/tex]

Let's apply 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]\[ 25 \times \frac{5}{9} = 13.888888\ldots \][/tex]

3. Round the result to the nearest whole number:

Rounding [tex]\(13.888888\ldots\)[/tex] gives us [tex]\(14\)[/tex].

Therefore, the temperature [tex]\(57^\circ F\)[/tex] is approximately [tex]\(14^\circ C\)[/tex] when rounded to the nearest whole number.
