Answer:
The answer is below
Step-by-step explanation:
Let us assume the rate of printing in machine A is x per hour and the rate for machine B is y. Given that machine B prints at half the rate of machine A, therefore:
y = (1/2)x (1)
Also, both machine produces 200 newspaper printouts, and both operate at different times for a total of 4 hours. Therefore:
200/x + 200/y = 4 (2)
Put y = (1/2)x in equation:
![\frac{200}{x}+\frac{200}{(\frac{1}{2} )x}=4\\ \\ \frac{200}{x}+\frac{400}{x}=4\\\\Multiply\ through\ by\ x:\\\\200+400=4x\\\\4x=600\\\\x=150](https://tex.z-dn.net/?f=%5Cfrac%7B200%7D%7Bx%7D%2B%5Cfrac%7B200%7D%7B%28%5Cfrac%7B1%7D%7B2%7D%20%29x%7D%3D4%5C%5C%20%5C%5C%20%5Cfrac%7B200%7D%7Bx%7D%2B%5Cfrac%7B400%7D%7Bx%7D%3D4%5C%5C%5C%5CMultiply%5C%20through%5C%20by%5C%20x%3A%5C%5C%5C%5C200%2B400%3D4x%5C%5C%5C%5C4x%3D600%5C%5C%5C%5Cx%3D150)
Put x = 150 in equation y:
y=(1/2)150 = 75
Therefore the rate of machine A is 150 newspapers per hour while that of machine B is 75 newspapers per hour
The length of OM is 4/3 the length of OJ, and the length of ON is 4/3 the length of OK. Thus, two pairs of sides from the triangles are proportional to each other.
Also, angle O from one of the triangles is equal to angle O of the other triangle because they are the same angle.
Thus, the two triangles are similar by SAS (side-angle-side) similarity theorem. This theorem is quite similar to the SAS congruence theorem.
To make a similarity statement, we just have to match corresponding parts when naming the triangle.
