You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. It bounces back up with every bounce,

but not quite all the way back up to you. After the first bounce it bounces back only 80 percent of the distance it was dropped from. The pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. So if before the first bounce the height is 50 meters, what height does the ball reach AFTER the fifth bounce? Round your answer to one decimal place and chose the correct response from the choices below:

Answer:

16.4 m to the nearest tenth.

Step-by-step explanation:

After the first bounce it rises to a height of 50*0.8 = 40 m.

After the next bounce it rises to  50*(0.8)^2 = 32 m

So after the 5th bounce it rises to  50(0.8)^5 = 16.4 m. (answer).

Aneli [31]

Answer:

20.4 ft

Step-by-step explanation:

Since they're similar triangles (same shape, but not necessarily the same size), then you can set them up as fractions to find the missing measure.

6/9.7 = ?/33

A quick way to do use this setup is to multiply 33 by 6, then divide by 9.7.

This gives you 20.4 ft

If ABC=DEF and MNO=PQR, then ABC=PQR by the transitive property.
zavuch27 [327]

Answer:

B. False

Step-by-step explanation:

There is not enough information to make that conclusion. The two statements are completely unrelated, so the transitive property cannot be used. None of the given statements say that ABC is congruent to MNO or PQR. That means that nothing can be assumed about DEF. To use the transitive property you would need proof that ABC=MNO or ABC=PQR. But neither of those statements are there so the answer is false.
