To convert a temperature from degrees Celsius to degrees Fahrenheit, you can use the following formula:
[tex]\[ F = \left( C \times \frac{9}{5} \right) + 32 \][/tex]
Let's apply this formula step-by-step to convert 40 degrees Celsius to degrees Fahrenheit:
1. Start with the given temperature in Celsius, which is [tex]\( 40^{\circ} C \)[/tex].
2. Multiply the Celsius temperature by [tex]\(\frac{9}{5}\)[/tex]:
[tex]\[ 40 \times \frac{9}{5} = 40 \times 1.8 = 72 \][/tex]
3. Add 32 to the result from the previous step:
[tex]\[ 72 + 32 = 104 \][/tex]
So, the temperature in degrees Fahrenheit is [tex]\( 104^{\circ} F \)[/tex].
The correct answer is:
B. [tex]\( 104^{\circ} F \)[/tex]
