Ed spoke to his cousin in Australia, who told him it was 25° C' that day. Ed wasn't sure if that was hot or cold, so he converted the temperature to degrees Fahrenheit.

Question

Use the formula F = 9/5C + 32 where F is degrees Fahrenheit and C is degrees
Celsius. What is the temperature in degrees Fahrenheit?
NOTE: Enter the number of degrees Fahrenheit in the box in order for this problem to be scored correctly.

Answer 1

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

\[ F = \frac{9}{5}C + 32 \]

Given that \( C = 25 \) degrees Celsius, we can plug this value into the formula:

\[ F = \frac{9}{5} \times 25 + 32 \]

First, calculate \( \frac{9}{5} \times 25 \):

\[ \frac{9}{5} \times 25 = 9 \times 5 = 45 \]

Now, add 32 to this result:

\[ F = 45 + 32 = 77 \]

So the temperature in degrees Fahrenheit is \( \boxed{77} \).
