which is equal to a temperature of 50°f?\n18°c\n46°c\n10°c\n32°c

Explanation:

Step1: Recall conversion formula

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

Step2: Substitute $F = 50$

Substitute $F = 50$ into the formula: $C=\frac{5}{9}(50 - 32)$.

Step3: Calculate the value inside parentheses

First, calculate $50-32 = 18$. So, $C=\frac{5}{9}\times18$.

Step4: Multiply

$\frac{5}{9}\times18=5\times2 = 10$.

Answer:

C. $10^{\circ}C$
