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

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

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

Answer :

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

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

where [tex]\( C \)[/tex] is the temperature in Celsius. Let's solve the problem step-by-step:

1. Identify the Celsius temperature: We are given that the Celsius temperature is [tex]\( 80^\circ \)[/tex].

2. Plug the Celsius temperature into the formula:

[tex]\[ F = \left(\frac{9}{5} \times 80\right) + 32 \][/tex]

3. Calculate the multiplication:

[tex]\[ \frac{9}{5} \times 80 = 144 \][/tex]

4. Add 32 to the result:

[tex]\[ 144 + 32 = 176 \][/tex]

Therefore, the temperature in Fahrenheit is [tex]\( 176^\circ \)[/tex].

The best answer choice from the provided options is:
a. [tex]\( 176^\circ \)[/tex] Fahrenheit
