Question

Sue graphed the formula for converting temperatures from Fahrenheit to Celsius. If the temperature is 50 degrees Fahrenheit, what is the temperature in Celsius? 5 degrees Celsius 10 degrees Celsius 15 degrees Celsius 20 degrees Celsius

Answer 1

For this case, we have by definition that:

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

If they tell us that the base temperature is 50 degrees Fahrenheit, then we substitute:

$C = (50-32) * \frac {5} {9}\\C = 18 * \frac {5} {9}\\C = 2 * 5\\C = 10$

Finally, the temperature equals 10 degrees Celsius.

Answer:

10 degrees Celsius
