Question

convert to fahrenheit. use c = 5/9(f - 32) or f = 9/5c+32, where f is the degrees in fahrenheit and c is the degrees in celsius. 20°c = □°f 20°c

Explanation:

Step1: Identify the formula

We use the formula $F=\frac{9}{5}C + 32$.

Step2: Substitute the Celsius value

Substitute $C = 20$ into the formula: $F=\frac{9}{5}\times20+32$.

Step3: Calculate the first - part

First, calculate $\frac{9}{5}\times20$. $\frac{9}{5}\times20=9\times4 = 36$.

Step4: Calculate the final result

Then, $F=36 + 32=68$.

Answer:

$68^{\circ}F$
