Step-by-step explanation:

The common ratio is a constant found in geometric sequences, denoted r in the equations for geometric sequences, when any term is divided by the term preceding it. In this case the common ratio is: 147/21=21/3=7=r So 7 is the common ratio.

My wife and I are Racing around a 400m track going opposite directions. I am running at 8 m/s and she has a head start of 50 met

Vlad [161]

Answer:

They both meet after 27 s.

Step-by-step explanation:

Length of track = 400 m

speed of man, v = 8 m/s

speed of woman, v' = 5 m/s

Woman is 50 m ahead of man.

Let the time taken to meet is t.

Let the man covered a distance d in time t o the woman covered a distance 400 - 50- d.

$\frac{d}{8}=\frac{400-50-d}{5}\\\\5 d = 8 (350-d)\\\\13 d = 2800\\\\d = 215.4 m$

The time taken is

$t=\frac{215.4}8}\\\\\\t=27 s$
