Is this a STARR test?
A. Divide 99 by 250
12) 2×2×2×2×2
14)(3/5) write it 4 times
16)2×2×2×5×5 and the rest I'm not sure but you should try using photomath :) it gives u the answers and the work!
See the attached figure to better understand the problem
we know that
AM=MD
so
triangle AMD is an isosceles right triangle
therefore
its height is half its width.
Then
AB = (1/2)AD----------Equation 1
Perimeter=2*[AB+AD]=34 in ---------> AB+AD=17-------> Equation 2
I substitute 1 in 2
(1/2)AD +AD = 17
(3/2)AD=17
AD=17*2/3----------> AD=34/3-------> 11 1/3 in
AB=(1/2)AD--------> AB=(1/2)*34/3--------> AB=17/3-------> AB=5 2/3 in
the answers are
AD=11 1/3 inAB = 5 2/3 in
Answer:
D)210 units ^2 I hope the answer is correct. I will be happy when I get 10 points
Triangles ABD and BCD are similar, because they are both right and share a common angle, and thus all three angles are equal.
This means that we can set the proportion

Plug the numbers and we have
