Question

convert 57°f to degrees celsius. round your answer to the correct number of significant figures.

Explanation:

Step1: Recall the conversion formula

The formula to convert Fahrenheit ($F$) to Celsius ($C$) is $C=\frac{5}{9}(F - 32)$.

Step2: Substitute the given value

Substitute $F = 57$ into the formula: $C=\frac{5}{9}(57 - 32)$.
First, calculate the value inside the parentheses: $57-32 = 25$.
Then, $C=\frac{5}{9}\times25=\frac{125}{9}\approx13.888\cdots$.

Step3: Round to significant figures

Since 57 has two - significant figures, we round our answer to two - significant figures. So $C\approx14^{\circ}C$.

Answer:

$14$
