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 .
Answer:
80
Step-by-step explanation:
So I here's my thought process on this:
200 divided by 2 is 100
100 - 40% is 60, leaving 40 behind.
So double that and it would be:
200 - 40% is 120
200 - 120 = 80
80% is the answer.
<span>Let's called the train that traveled south train A, and the train that traveled east train B
After 3 hours, train A is 180 miles South
and Train B is 150 miles East
Using Pythagoras, distance between is sqrt(180^2 + 150^2)
30 sqrt(6^2 + 5^2) = 30sqrt(36 + 25) = 30sqrt 61 = 234.307 miles</span>
C would be the answer because to find the area of a circle A=pi times radius squared and you put that in a calculator and get 50.24
Answer:
C
Step-by-step explanation:
Volume = base * height.
The area of the base = base * height/2
That means the area of the triangular base is 8 * 5.1/2 = 20.4
The height is 9, so the volume is 20.4 * 9.
That means the volume is 183.6, which is C
