Answer:
The estimate is reasonable.
Step-by-step explanation:
Jamie's estimate seems reasonable.
We can see that there is (-24/27) in the bracket, first of all there is negative sign so there will be negative sign in the answer. Moreover, 24 is near to half of 27 so fraction will result in -0.5XXXXX and multiplying it with 1.4 will increase it around -0.75.
We can solve the given fraction for confirmation,
So,
which is near to -0.75 so the estimate of Jamie was right ..
A = 1/2bh
Divide h by both sides.
A/h = 1/2b
Divide 1/2 by both sides.
b = 2a/h
The top is a triangle with sides 7 and 5.4 Use the Pythagorean theorem to find the 3rd length.
3rd sides = sqt(7^2 + 5^2( = sqrt(49+25) = sqrt(74)
This side is the base of the lower rectangle.
The dotted line is the hypotenuse of a right triangle.
Use the Pythagorean theorem to solve.
sqrt(10^2 + sqrt(74)^2) = sqrt(174)
The dotted line = sqrt(174)
It’s D because when you draw a line anywhere on any of the graphs, it should only hit a line once, so it can’t be A,B, and C
