Part A Sarah creates an area model to solve the problem.
Write a number on each blank to complete the area model.
Use the numbers in the box.
10 1 30 50 2,000
900
90 540 300 200 5,400 5
200
90
50
6
1,200

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

191 students play sports and ninety-seven 10th graders were surveyed.

step-by-step explanation:

answer is because 4×10=40

and 98×4= is 392
