Answer:
(a) 2 degree celsius per hour
(b) 3 degree celsius per hour.
Step-by-step explanation:
From the question,
(a) Avearge rate of rise in temperature per hour(T') = Rise in temperature(T)/Time required for the rise(t).
T' = T/t.................... Euqation 1
Rise in temperature (T) = 4 degree celsius, t = 10.00 am to noon = 2 hours.
Substitute into equation 1
T' = 4/2
T' = 2 degree celsius per hour.
(b) Also,
Average rate of fall in temperature per hour (T') = Fall in temperature (T)/Time(t)
T' = T/t
Given: T = 6 degree celsius, t = 3:00 pm to 5:00 pm = 2 hours
T' = 6/2
T' = 3 degree celsius per hour
The answer would be 0 because 0 is a perfect square. Hope this helps :)
Your key "word" is the parentheses ( ) that encloses the -19.98. In this case, think of the parentheses as saying multiplication. It means that in all equations, btw.
so, I write six checks at 19.98. The negative sign in front of the 19.98 signifies a decrease in the checking account for each check written
