99 degrees warmer because since -27 a negative number you have to add 27 to get to 0 so Alaska is then 72 degrees which is a positive number so you add 72+27 and get 99
This is right solution:
12^2+9^2=The third side^2
144+81=The third side^2
225=The third side^2
√225=The third side
15=The third side
Hope it helps....
Answer:

Step-by-step explanation:
Answer:
C
Step-by-step explanation:
You just find the rate of change. So you would divide 30/1 which equals 30. So the equation is y=30x.
Overall dimensions of the page in order to maximize the printing area is page should be 11 inches wide and 10 inches long .
<u>Step-by-step explanation:</u>
We have , A page should have perimeter of 42 inches. The printing area within the page would be determined by top and bottom margins of 1 inch from each side, and the left and right margins of 1.5 inches from each side. let's assume width of the page be x inches and its length be y inches So,
Perimeter = 42 inches
⇒ 
width of printed area = x-3 & length of printed area = y-2:
area = 

Let's find
:
=
, for area to be maximum
= 0
⇒ 
And ,

∴ Overall dimensions of the page in order to maximize the printing area is page should be 11 inches wide and 10 inches long .
