if it is 40 degrees celsius, what is the temperature in fahrenheit?\na. 40 degrees\nb. 104 degrees\nc. 54…

Explanation:

Step1: Recall conversion formula

The formula to convert Celsius ($C$) to Fahrenheit ($F$) is $F=\frac{9}{5}C + 32$.

Step2: Substitute given value

Given $C = 40$, substitute into the formula: $F=\frac{9}{5}\times40+32$. First, calculate $\frac{9}{5}\times40$: $\frac{9}{5}\times40=9\times8 = 72$. Then, $F=72 + 32$.

Step3: Calculate final result

$F=104$.

Answer:

104 degrees (Option B)
