Answer:
48
Step-by-step explanation:
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
16:64 (Rowley to Rivera homework ratio)
14:60 (Rowley to Rivera exit ratio)
The ratios aren't equivalent because when they are simplified, the first ratio is 1:4, and the second is 7:30, thus meaning they aren't equal.
The value that should be used when one wants to determine the the amount of beach remaining after each is the common ration. This is because the the common ratio gives the percentage decrease or increase in value proportional to the original value. In our case the common ratio that should not miss in the model is 1.1%~ 0.011.
Answer is: the common ratio is 1.1%
