Answer:
The temperature at 9:00 is 14° C.
Step-by-step explanation:
At noon, the temperature was 6° C.
By 5:00, the temperature had dropped to -2° C.
Every hour until 9:00, the temperature rose 4°, so 4•4 is 16.
16 + -2 is 14.
So, the temperature at 9:00 is 14° C.
Answer:
The temperature at 9:00 P.M is [tex]14^\circ C[/tex]
Step-by-step explanation:
We are given the following in the question:
Temperature at 12:00 = [tex]6^\circ C[/tex]
Over the next five hours the temperature dropped another 8 degrees.
Thus, temperature at 5:00 P.M =
[tex]6 - 8 = -2^\circ C[/tex]
Then every hour until 9:00 temperature rose 4 degrees.
Temperature at 6:00 P.M =
[tex]-2 + 4= 2^\circ C[/tex]
Temperature at 7:00 P.M =
[tex]2+4= 6^\circ C[/tex]
Temperature at 8:00 P.M =
[tex]6+4= 10^\circ C[/tex]
Temperature at 9:00 P.M =
[tex]10+4= 14^\circ C[/tex]
Thus, the temperature at 9:00 P.M is [tex]14^\circ C[/tex]
