To convert a temperature from degrees Celsius to degrees Fahrenheit, you can use the following formula:
[tex]\[ \text{Temperature in Fahrenheit} = \left(\text{Temperature in Celsius} \times \frac{9}{5}\right) + 32 \][/tex]
Given the temperature in Celsius is 30 degrees, follow these steps to find the temperature in Fahrenheit:
1. Multiply the Celsius temperature by [tex]\(\frac{9}{5}\)[/tex]:
[tex]\[ 30 \times \frac{9}{5} = 30 \times 1.8 = 54 \][/tex]
2. Add 32 to the result from the first step:
[tex]\[ 54 + 32 = 86 \][/tex]
Thus, the temperature in degrees Fahrenheit is [tex]\( 86^{\circ} F \)[/tex].
Therefore, the correct answer is:
B. [tex]\( 86^{\circ} F \)[/tex]
