What will the temperature be in degrees Fahrenheit when it is [tex]80^{\circ}[/tex] Celsius outside? (Recall the formula [tex]F = \frac{9C}{5} + 32[/tex].)

A. [tex]176^{\circ}[/tex] Fahrenheit
B. [tex]76.0^{\circ}[/tex] Fahrenheit
C. [tex]150.4^{\circ}[/tex] Fahrenheit
D. [tex]201.6^{\circ}[/tex] Fahrenheit

Please select the best answer from the choices provided:
A
B
C
D

Answer :

To convert a temperature from Celsius to Fahrenheit, we use the formula:

[tex]\[ F = \left(\frac{9}{5} \times C\right) + 32 \][/tex]

Here, [tex]\( C \)[/tex] represents the temperature in degrees Celsius.

Let's convert [tex]\( 80^\circ \)[/tex] Celsius to Fahrenheit:

1. Multiply the Celsius temperature by [tex]\(\frac{9}{5}\)[/tex]:
[tex]\[
\frac{9}{5} \times 80 = 144
\][/tex]

2. Add 32 to the result from step 1:
[tex]\[
144 + 32 = 176
\][/tex]

Therefore, [tex]\( 80^\circ \)[/tex] Celsius is equal to [tex]\( 176^\circ \)[/tex] Fahrenheit.

The correct answer is:
A. [tex]\( 176^\circ \)[/tex] Fahrenheit
