Answer:
0.50 seconds
Step-by-step explanation:
The time it takes for an echo to return is the time it takes for the sound to make the round trip between the source and the reflecting object.
The boulder is 80 m away from the source, so the round-trip distance is 2×80 m = 160 m. At a speed of 320 m/s, it takes sound ...
(160 m)/(320 m/s) = 0.50 s
to make the round-trip.
It will take 0.50 seconds to hear the echo.
Answer:
It was the withdrawal of the Union troops from the South.
Step-by-step explanation:
The South could go back to blatant mistreatment and practically slavery without the oversight of the Northern troops- so all of the progress that was made was for nothing. That was when Reconstruction ended.
The answer is B, 30 x 5 The answer is reasonable. Ryder is correct. It reasonable because if 25 x 5 is 125, then 30 x 5 won't be too much to be unreasonable. 30 x 5 is 150, therefore it is only 25 windows higher, so it is reasonable. Hope this helps! :)

Answer:
y=17/3x+2
Step-by-step explanation:
Get 2 points from the graph
(3;19) (-10;2)
Grad=change in y/change in x
=2-19/-10-3
=-17/-13
=17/3
y=mx+c
19=17/13(3)+c
19=17+c
19-17=c
2=c
y=17/13x+2.
Well I think you are supposed to find the equation of the line so I think that's it.
