Chapter 2: Q. 235 (page 147)

Converting temperature
While on a tour in Greece, Tatyana saw that the temperature was $40 °$ Celsius. Solve for F in the formula $C = \frac{5}{9} (F - 32)$ to find the Fahrenheit temperature.

Short Answer

Expert verified

The temperature in Fahrenheit is $104 °$ .

Step by step solution

Step 1. Given

The temperature in Celcius is $40 °$ .

Step 2. Isolating the Variable

Rearrange the terms of the equation, $C = \frac{5}{9} (F - 32)$ and isolate the variable Fon one side of the equation.

$\frac{9}{5} C = (F - 32) \frac{9}{5} C + 32 = F F = \frac{9}{5} C + 32$

So, the formula for temperature in Fahrenheit is $F = \frac{9}{5} C + 32$ .

Step 3. Substitution

Substitute $C = 40 °$ into $F = \frac{9}{5} C + 32$ and solve for F.

$F = \frac{9}{5} \times 40 + 32 = 72 + 32 = 104$

So, the temperature in Fahrenheit is $104 °$

Step 4. Conclusion

The temperature in Fahrenheit is $104 °$ .
