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 [tex]$57^\circ F$[/tex] to Celsius, we use the conversion formula:
[tex]$$
C = \frac{5}{9}(F - 32)
$$[/tex]

Follow the steps below:

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

2. Multiply the result by [tex]$\frac{5}{9}$[/tex]:
[tex]$$
C = \frac{5}{9} \times 25 \approx 13.8889
$$[/tex]

3. Round the result to the nearest whole number:
[tex]$$
13.8889 \approx 14
$$[/tex]

Thus, [tex]$57^\circ F$[/tex] is approximately [tex]$14^\circ C$[/tex] when rounded to the nearest whole number.
