Convert 40 degrees Celsius to Fahrenheit.

To convert degrees Celsius to degrees Fahrenheit, you can use the formula:

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

In this case, you've been given 40 degrees Celsius.

1. Start by multiplying 40 by ( \frac{9}{5} ):

[ 40 \times \frac{9}{5} = 40 \times 1.8 = 72 ]

2. Next, add 32 to this product:

[ 72 + 32 = 104 ]

Therefore, 40 degrees Celsius is equivalent to 104 degrees Fahrenheit. This calculation correctly follows the conversion formula, leading to the accurate conclusion that 40 degrees Celsius translates to 104 degrees Fahrenheit, which is why this option is the correct answer.
