Question

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

Explanation:

Step1: Rearrange formula for $F$

Start with $C = \frac{5}{9}(F - 32)$. Multiply both sides by 9: $9C = 5(F - 32)$. Divide by 5: $\frac{9C}{5} = F - 32$. Rearrange to solve for $F$: $F = \frac{9C}{5} + 32$

Step2: Substitute $C=50$ into formula

$F = \frac{9\times50}{5} + 32$

Step3: Calculate the result

First compute $\frac{450}{5}=90$, then $90 + 32 = 122$

Answer:

122°F
