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 formula for F

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

Step2: Substitute C = 50

Substitute $C = 50$ into the formula $F=\frac{9}{5}C+32$. So $F=\frac{9}{5}\times50+32$.

Step3: Calculate the value of F

$\frac{9}{5}\times50 = 90$, then $F=90 + 32=122$.

Answer:

C. $122^{\circ}F$
