Question

h) 30°c = 86 °f

Explanation:

Step1: Recall the conversion formula

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

Step2: Substitute the value of $C$

Given $C = 30$, substitute it into the formula: $F=\frac{9}{5}\times30+32$.
First, calculate $\frac{9}{5}\times30 = 9\times6=54$.
Then, $F = 54 + 32$.

Step3: Calculate the result

$54+32=86$.

Answer:

$86$
