The temperature in Antarctica at noon is 14°F. By 9:00PM, the temperature had dropped by 16.2 degrees. What was the temperature at 9:00PM?
A –2.2°F
B 2.2°F
C –30.2°F
D 30.2°F
To find the temperature at 9:00 PM, we need to subtract the temperature drop of 16.2 degrees from the temperature at noon.
Temperature at 9:00 PM = Temperature at noon - Temperature drop
Temperature at 9:00 PM = 14°F - 16.2°F
This gives us a negative value, so we need to subtract a negative, which is the same as adding a positive.
Temperature at 9:00 PM = 14°F + 16.2°F
Temperature at 9:00 PM = 30.2°F
Therefore, the temperature at 9:00 PM in Antarctica was 30.2°F.
The correct answer is D) 30.2°F.
To find the temperature at 9:00 PM, we need to subtract 16.2 degrees from the temperature at noon.
Temperature at noon: 14°F
Temperature dropped: 16.2 degrees
Subtracting 16.2 degrees from 14°F:
14°F - 16.2°F = -2.2°F
Therefore, the temperature at 9:00 PM was -2.2°F.
Answer: A) -2.2°F
To find the temperature at 9:00 PM, we need to subtract 16.2 degrees from the temperature at noon.
The temperature at noon is given as 14°F. To find the temperature at 9:00 PM, we subtract 16.2°F from 14°F.
14°F - 16.2°F = -2.2°F
Therefore, the temperature at 9:00 PM in Antarctica would be -2.2°F. Thus, the correct answer is A) -2.2°F.
