Right.
I don't get how number 2 is wrong we did that one in class
7o'clock
Let's go through each question and calculate the temperature changes step by step:
1. At 5 o'clock in the morning, the temperature was -13o, and by 10:00 A.M., it was +12o. To find out how much the temperature rose, we subtract the initial temperature (-13o) from the final temperature (+12o): 12o - (-13o) = 12o + 13o = 25o.
2. The temperature rose from -12o to +23o by noon. To calculate the temperature change, we subtract the initial temperature (-12o) from the final temperature (+23o): 23o - (-12o) = 23o + 12o = 35o.
3. In the afternoon, the temperature fell rapidly from +23o to -1o. To find the change, we subtract the initial temperature (+23o) from the final temperature (-1o): -1o - 23o = -1o - 23o = -24o.
4. By 7:00 P.M., the temperature was -9o. To calculate the temperature change from 10:00 A.M., we subtract the initial temperature (+23o) from the final temperature (-9o): -9o - 23o = -9o - 23o = -32o.
5. The midnight temperature was 35o colder than noon. So we subtract 35o from the noon temperature (23o - 35o) to get the midnight temperature: -12o.
6. If the temperature rose 120o between midnight and 6:00 A.M., we add 120o to the midnight temperature (-12o + 120o) to get the temperature at 6:00 A.M: 108o.
So the calculations for each question are as follows:
1. 25o
2. 35o
3. -24o
4. -32o
5. -12o
6. 108o
Yes, the answers provided in the question are correct.
