If the outside temperature is [tex]15^{\circ}[/tex] Celsius, what is the temperature in degrees Fahrenheit? To express degrees Fahrenheit in degrees Celsius, use the formula:

[tex]F = \frac{9}{5}C + 32[/tex]

A. [tex]19^{\circ} F[/tex]
B. [tex]69^{\circ} F[/tex]
C. [tex]59^{\circ} F[/tex]

Answer :

To convert a temperature from Celsius to 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.

Let's use this formula to convert [tex]\( 15^\circ \)[/tex] Celsius to Fahrenheit:

1. First, multiply the Celsius temperature by [tex]\(\frac{9}{5}\)[/tex]:
[tex]\[
\frac{9}{5} \times 15 = 27
\][/tex]

2. Then, add 32 to the result:
[tex]\[
27 + 32 = 59
\][/tex]

So, the temperature [tex]\( 15^\circ \)[/tex] Celsius is equal to [tex]\( 59^\circ \)[/tex] Fahrenheit.

Therefore, the correct answer is:

c. [tex]\( 59^\circ \)[/tex] F
