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 following formula:

[tex]\[
\text{Temperature in } ^\circ C = (\text{Temperature in } ^\circ F - 32) \times \frac{5}{9}
\][/tex]

Let's apply this formula to the given temperature of [tex]\(57^\circ F\)[/tex]:

1. Subtract 32 from the Fahrenheit temperature:
[tex]\[
57 - 32 = 25
\][/tex]

2. Multiply the result by [tex]\(\frac{5}{9}\)[/tex]:
[tex]\[
25 \times \frac{5}{9} = 13.888\ldots
\][/tex]

3. Round 13.888... to the nearest whole number:
[tex]\[
\text{Rounded result} = 14
\][/tex]

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