2.8 times the number q is 11.76. which equation shows the relationship between 2.8, 11.76, and q and then find the value of q? a. q2.8=11.76q2.8=11.76 b.q = 32.928 2.8q = 11.76 q = 4.2 c.q + 2.8 = 11.76 q = 8.96 d. 11.76q = 2.8 q = 0.24

2.8*q=11.76
2.8q=11.76
q=4.2

I can't see the options very well but it is something along those lines.

Hope this helps :)

1st drop : 48
1st bounce:24
2nd drop : 12
2nd bounce: 6 and so on and so forth:

This is a geometric progression with 1st term a = 48 and common ratio r= 1/2

The sum of all terms in a G.P is 

S=a(1 - rⁿ⁻¹)/(1-r), 
S = 48(1 - r⁴)/(1-r). Replace r by 1/2
S = 48[1-(1/2)⁴]/(1/2)

S = 90 ft
