Theaverage change in temperature in one hour will be 3 °F.
It is given that in 12 hours the temperature dropped 36 degrees Fahrenheit.
We have to findout that what was the average change in temperature in one hour ?
What do you mean by average ?
Average of numbers is the ratio of sum of all numbers to the no. of numbers.
As per the question ;
Temperature drop/change in 12 hours of period ;
= 36 °F
Temperature change in 1 hour will be ;
= 36 / 12
= 3 °F
Thus , the average change in temperature in one hour will be 3 °F.

Answer:
3 degrees
Step-by-step explanation:
36 degrees divided by the hours it took to drop that much will get you the answer
36/12 is 3
Answer:
P = 40.56 in (ANS)
Step-by-step explanation:
radius = 8/2 = 4 in
semi-circle perimeter = pi * R = 3.14 * 4 = 12.56 in
figure perimeter = 12.56 + 10 + 8 + 10 = 40.56 in (ANS)
Answer:
3x^2 + 3xz + 2y^2 - 2yz - xy
Step-by-step explanation:
(1) multiply it to get
3x^2 - 3xy + 3xz and 2yx + 2y^2 - 2yz
add similar variables (-3xy + 2yx)
( the order of the variables doesn't matter xy or yx is the same)
we get -xy
and then after that simplifying we get 3x^2 + 3xz + 2y^2 - 2yz - xy
Answer:
Step-by-step explanation:
hello :
3x(x-y+z) + 2y (x+y-z) = 3x²-3xy+3xz +2yx+2y²-2yz
3x(x-y+z) + 2y (x+y-z) = 3x² -xy+3xz -2yz+2y²
