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 degrees Fahrenheit to degrees Celsius, you can use the following formula:

[tex]\[ °C = \frac{5}{9}(°F - 32) \][/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]\[
\frac{5}{9} \times 25 \approx 13.8889
\][/tex]

3. Round the result to the nearest whole number:

[tex]\[
13.8889 \approx 14
\][/tex]

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