The morning temperature was -3 degrees C. By afternoon it had warmed to 8 degrees C. How many degrees had the temperature risen?

Subtract the final temperature to the initial temperature:

8 - (-3)
= 8 + 3
= 11

8+3=11

Final temperature is 11 degrees Celsius or 11 degrees Fahrenheit, whichever one.

IN THE MORNING THE TEMPERATURE WAS +4 DEGREES CELCCIUS. BY THE AFTERNOON IT WAS -9 DEGREES CELSIUS. WHAT WAS THE CHANGE IN TEMPERATURE

Well, it looks like the temperature had quite the "rise"! From -3 degrees C in the morning to 8 degrees C in the afternoon, that's a total increase of 11 degrees. Looks like someone turned up the heat!

To calculate how many degrees the temperature had risen, we need to find the difference between the afternoon temperature and the morning temperature.

In this case, the morning temperature was -3 degrees Celsius, and the afternoon temperature was 8 degrees Celsius.

To find the difference, we subtract the morning temperature from the afternoon temperature:

8 degrees Celsius - (-3) degrees Celsius = 8 degrees Celsius + 3 degrees Celsius = 11 degrees Celsius.

Therefore, the temperature had risen by 11 degrees Celsius.
