Answer:
Ratio of triangle AMN to square ABCD = 1/8
Step-by-step explanation:
area AMN = Area ABN - Area MNB
Where AB = BC = x
Area AMN = [ ½ *( x * ½x )] - [ ½( ½x * ½x)] = x²/8
Area of ABCD = x* x = x²
So therefore:
The ratio of area of triangle AMN to area of square ABCD would be
= (x²/8) / x²
=1/8
Answer:
210
Step-by-step explanation:
29*7 = 203, 203 is the closest number to 210!
44 * 10 = 440 Hope this help.
Answer:
Step-by-step explanation:
The best way to do this is to let a graphing program do it. You could do it from a chart, but a graphing program can be useful for that as well. We'll make up a mini chart here
x method y
-3 (-3)^2 + 2(-3) + 3 = 6
-2 (-2)^2 + 2(-2) + 3 = 3
-1 (-1)^2 + 2(-1) + 3 = 2
0 3
1 (1)^2 + 2(1) + 3 6
2 (2^2) + 2(2) + 3 11
3 (3)^2 +2(3) + 3 18
See the graph below.
You can pick it out from the graphs you were given.
You would do 5^2•3.14
Which would equal 78.5
So D is ur answer
