When Paula went to sleep, it was 6 degrees Fahrenheit. When she woke up, the temperature has dropped to -4 degrees. What was the change in temperature while Paula was asleep?
it dropped 6 to zero, then dropped another 4 to -4
Total drop: 6-(-4) = 6+4 = 10
but since drops are negative changes, the total change was -10
To find the change in temperature while Paula was asleep, we need to calculate the difference between the temperature when she went to sleep and the temperature when she woke up. We can do this by subtracting the initial temperature from the final temperature.
The initial temperature when Paula went to sleep was 6 degrees Fahrenheit, and the final temperature when she woke up was -4 degrees Fahrenheit. So, the change in temperature can be calculated as:
Change in temperature = Final temperature - Initial temperature
Change in temperature = (-4) - 6
Change in temperature = -10 degrees Fahrenheit
Therefore, the change in temperature while Paula was asleep is -10 degrees Fahrenheit.
