Answer :
To convert a temperature from degrees Celsius to degrees Fahrenheit, you can use the formula:
[tex]\[ F = \left( \frac{9}{5} \times C \right) + 32 \][/tex]
where [tex]\( F \)[/tex] is the temperature in degrees Fahrenheit and [tex]\( C \)[/tex] is the temperature in degrees Celsius.
Step-by-step solution:
1. Begin with the given temperature in Celsius: 21.0 °C.
2. Multiply the Celsius temperature by [tex]\(\frac{9}{5}\)[/tex].
[tex]\[ \frac{9}{5} \times 21.0 = 37.8 \][/tex]
3. Add 32 to the result from step 2.
[tex]\[ 37.8 + 32 = 69.8 \][/tex]
Therefore, 21.0 °C is equal to 69.8 °F.
[tex]\[ F = \left( \frac{9}{5} \times C \right) + 32 \][/tex]
where [tex]\( F \)[/tex] is the temperature in degrees Fahrenheit and [tex]\( C \)[/tex] is the temperature in degrees Celsius.
Step-by-step solution:
1. Begin with the given temperature in Celsius: 21.0 °C.
2. Multiply the Celsius temperature by [tex]\(\frac{9}{5}\)[/tex].
[tex]\[ \frac{9}{5} \times 21.0 = 37.8 \][/tex]
3. Add 32 to the result from step 2.
[tex]\[ 37.8 + 32 = 69.8 \][/tex]
Therefore, 21.0 °C is equal to 69.8 °F.
