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}(C) + 32[/tex].

A. 93 3/5 Degrees
B. 78 Degrees
C. 62 3/5 Degrees
D. 68 Degrees

Answer :

To convert 20 degrees Celsius to degrees Fahrenheit, you can use the formula:

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

Now, let's apply this formula step-by-step:

1. Multiply the Celsius temperature by 9/5:

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

2. Add 32 to the result:

[tex]\[ 36 + 32 = 68 \][/tex]

Therefore, when the temperature is 20 degrees Celsius, it is 68 degrees Fahrenheit.

So, the correct answer is option 8-D 68 Degrees.
