Question

question 5 if the temperature is 20. °c, what is the corresponding temperature on the fahrenheit scale? 68 °f -22 °f 239 °f 94 °f

Explanation:

Step1: Recall the conversion formula

The formula to convert Celsius to Fahrenheit is $F = \frac{9}{5}C + 32$, where $C$ is the temperature in Celsius and $F$ is the temperature in Fahrenheit.

Step2: Substitute the given value

We are given $C = 20^{\circ}\text{C}$. Substitute this into the formula:
$F=\frac{9}{5}\times20 + 32$
First, calculate $\frac{9}{5}\times20$. $\frac{9}{5}\times20 = 9\times4=36$ (since $\frac{20}{5} = 4$).
Then, add 32: $36 + 32=68$.

Answer:

$68^{\circ}\text{F}$ (corresponding to the option "68 °F")
