Expert Solution

## Answer to Problem 105E

The corresponding temperature range in Fahrenheit scale is 68F86.

### Explanation of Solution

Formula used:

The Fahrenheit scale is converted into Celsius scale by the relation C=59(F32).

Calculation:

The range in Celsius is 20C30.

Substitute C=59(F32) in 20C30 as follows:

20C302059(F32)30

Multiply 95 in 2059(F32)30.

20×9559(F32)×9530×9536(F32)54

Add 32 in 36(F32)54.

36+32F32+3254+3268F86

Therefore, the corresponding temperature range in Fahrenheit scale is 68F86.
