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]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

Answer :

- Substitute the given Celsius temperature ($80^{\circ}C$) into the conversion formula.
- Calculate $\frac{9}{5} \times 80$ which equals $144$.
- Add $32$ to $144$.
- The temperature in Fahrenheit is $\boxed{176^{\circ}F}$.

### Explanation
1. Understanding the problem
We are given the temperature in Celsius, which is $80^{\circ}C$, and we need to convert it to Fahrenheit using the formula $F = \frac{9}{5}C + 32$.

2. Substituting the value of C
Now, we substitute the value of $C$ into the formula: $$F = \frac{9}{5} \times 80 + 32$$

3. Calculating F
Next, we perform the calculation: $$F = \frac{9 \times 80}{5} + 32 = \frac{720}{5} + 32 = 144 + 32 = 176$$

4. Final Answer
Therefore, the temperature in Fahrenheit is $176^{\circ}F$.

### Examples
Converting temperatures is a common task in many real-world scenarios. For example, if you are traveling to a country that uses Celsius and you are used to Fahrenheit, you would need to convert the temperature to understand how hot or cold it is. Similarly, in scientific research, it is often necessary to convert temperatures between Celsius and Fahrenheit to compare data or perform calculations. This conversion is also useful in cooking, where recipes may provide temperatures in different units.
