When the temperature is 20 degrees Celsius (C), what is it on the Fahrenheit (F) scale?

(Use the following formula)

Degrees Fahrenheit = [tex]\frac{9}{5}[/tex](C) + 32

A. 93 [tex]\frac{3}{5}[/tex] degrees
B. 78 degrees
C. 62 [tex]\frac{3}{5}[/tex] degrees
D. 68 degrees

Answer :

We start with the formula:

[tex]$$
F = \frac{9}{5} C + 32
$$[/tex]

Substituting the temperature [tex]$C = 20$[/tex] into the formula:

[tex]$$
F = \frac{9}{5} \times 20 + 32
$$[/tex]

First, compute the product:

[tex]$$
\frac{9}{5} \times 20 = 36
$$[/tex]

Then, add [tex]$32$[/tex] to the product:

[tex]$$
F = 36 + 32 = 68
$$[/tex]

Thus, when the temperature is [tex]$20^\circ C$[/tex], it is [tex]$68^\circ F$[/tex]. The correct answer is D.
