Upon looking, you should see 4 points where the graphs intersect, so there are 4 solutions to the non-linear system of equations.
The wale school has the lower student teacher ratio
8.900-30
x-35
So the x equals to 35*900/30
x=30*35=1050 Variant H
9. 2*21.28+7.99=50.55 Variant B
Answer:
1:8
Step-by-step explanation:
Given that in square ABCD, point M is the midpoint of side AB and point N is the midpoint of side BC.
Let the side of the square be a.
Area of square ABCD = 
The triangle AMN is having two legs of a right triangle as half of side of the square
i.e. Triangle AMN has base = height = a/2
So area of triangle AMN = 
Ratio of the area of triangle AMN to area of square ABCD
= 1:8
