the temperature at 12 noon was 10 degree Celsius above 0 if it degrees @ to degree Celsius for our U turn you till midnight at what time would the temperature be 8 degree Celsius belong zero what would be the temperature at midnight
Answers
Answer:
Step-by-step explanation:
Let noon be time t = 0 hr.,
then the temperature T in degrees Celsius at t hr. would be:
T = 10 - 2t
Now,
To find when the temperature is 8°C below zero,
T = -8
10 - 2t = -8
2t = 18
t = 9
Thus, the temperature is 8°C below zero at 9:00 pm.
To find the temperature at midnight,
use t = 12:00
T = 10 - 2(12) = 10 - 24 = -14
Thus, the temperature at midnight is 14∘C below zero.
Hope this helps you...,
