Question

the formula to convert °f to °c is c = \frac{5}{9}(f - 32). convert 50°c to °f. 10°f 20°f 122°f 132°f

Explanation:

Step1: Rearrange the conversion formula

Starting with $C=\frac{5}{9}(F - 32)$, we first multiply both sides by $\frac{9}{5}$ to get $\frac{9}{5}C=F - 32$. Then we add 32 to both sides to solve for $F$, so $F=\frac{9}{5}C+32$.

Step2: Substitute the value of C

Given $C = 50$, we substitute it into the formula $F=\frac{9}{5}\times50+32$. First, calculate $\frac{9}{5}\times50 = 90$. Then $F=90 + 32$.

Step3: Calculate the value of F

$90+32=122$.

Answer:

C. $122^{\circ}F$
