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 the temperature from Fahrenheit to Celsius, we use the formula:

[tex]\[ C = \frac{5}{9} \times (F - 32) \][/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]\[ 25 \times \frac{5}{9} \approx 13.888... \][/tex]

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

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