**Celsius and Fahrenheit**

The formula to convert from Celsius to Fahrenheit is [tex] F = \frac{9}{5} C + 32 [/tex].

Use this formula to complete the statements below. Round your answers to the nearest tenth as needed.

- If the temperature is 70 degrees Fahrenheit, that is equivalent to __ degrees Celsius.
- If the temperature is 40 degrees Celsius, that is equivalent to __ degrees Fahrenheit.

Answer :

Final answer:

To convert temperatures from Celsius to Fahrenheit we use the formula F = 9/5C + 32. When wanting to convert from Fahrenheit to Celsius, we use the formula C = (F-32) * 5/9. For example, 70 degrees Fahrenheit is equivalent to 21.1 Celsius, and 40 degrees Celsius is equivalent to 104 Fahrenheit.

Explanation:

The formula for converting temperatures from degrees Celsius to Fahrenheit is F = 9/5C + 32. If you want to convert Fahrenheit to Celsius, you can rearrange the formula to solve for C = (F-32) * 5/9.

For example, if the temperature is 70 degrees Fahrenheit and we want to convert it to Celsius: C = (70-32) * 5/9 = 21.1 roughly when rounded to the nearest tenth. So, 70 degrees Fahrenheit is the same as 21.1 degrees Celsius.

Now, if the temperature is 40 degrees Celsius and we want to convert it to Fahrenheit: F = 9/5 * 40 + 32 = 104. Thus, 40 degrees Celsius is equivalent to 104 degrees Fahrenheit.
