Answer :
To convert degrees Celsius to degrees Fahrenheit, you can use the formula:
[tex]\[ F(c) = \frac{9}{5} \cdot c + 32 \][/tex]
Here, [tex]\( c \)[/tex] represents the temperature in degrees Celsius.
Let's apply this formula to convert 20 degrees Celsius to degrees Fahrenheit:
1. Start with the Celsius temperature given, which is 20 degrees.
2. Multiply 20 by [tex]\(\frac{9}{5}\)[/tex].
[tex]\[ \frac{9}{5} \cdot 20 = \frac{180}{5} = 36 \][/tex]
3. Add 32 to the result from step 2.
[tex]\[ 36 + 32 = 68 \][/tex]
So, 20 degrees Celsius is equal to 68 degrees Fahrenheit.
The correct answer is D. 68.
