At noon the temperature in Alaska is 6°F. If the temperature drops 4°F per hour, what will the temperature be at 9:00 PM?

The temperature at 9:00 PM will be °F

-45

Are you just throwing out guesses?

How many hours from noon to 9:00 pm ??
starting at +6 it decreases 4° each hour, so .....

Temp. = 6 - 4*9 =

To determine the temperature at 9:00 PM, we need to calculate the number of hours between noon and 9:00 PM and then calculate the drop in temperature during that time.

First, let's determine the number of hours between noon and 9:00 PM:
9:00 PM is 9 hours later than noon.

Next, we need to calculate the drop in temperature per hour:
The temperature drops 4°F per hour.

Now, we can calculate the overall drop in temperature:
Since the temperature drops 4°F per hour, and there are 9 hours between noon and 9:00 PM, the temperature will have dropped 4°F * 9 = 36°F.

Finally, we subtract the drop in temperature from the initial temperature at noon to find the temperature at 9:00 PM:
6°F (initial temperature) - 36°F (drop in temperature) = -30°F

Therefore, the temperature at 9:00 PM in Alaska will be -30°F.
