In Oslo, the average temperature ranges from -10 degrees to 18 degrees celsius.?

Question

use a compound inequality to convert these temperatures to the fahrenheit scale.

Answer 1

-10 <= TempOslo <= 18

Coverting to Fahrenheit scale you will need to multipy by 1.8 and add 32 on both sides

32 - 10*1.8 <= TempOlso <= 32 + 18*1.8

14 <= TempOslo <= 64.4

Answer 2

The relative humidity is 42.58% from an Excel spreadsheet program I have that calculates solutions to HVAC problem temperature, pressure, and humidity combinations more accurately than taking the solutions off a psychrometric chart.
