Answer:
answer is b
yes because 15-8=7 is true
Step-by-step explanation:
15-8=7
5 sec
Hit the water, means h = 0
Solve -16t^2 + 68t +60 =0
4t^2 - 17t - 15 = 0
(4t + 3)(t - 5) = 0
so t = 5 sec
Work Shown:
(p+2q)/p = 7/5
(p/p)+(2q/p) = 7/5
1 + 2(q/p) = 7/5
2(q/p) = 7/5 - 1
2(q/p) = 7/5 - 5/5
2(q/p) = (7-5)/5
2(q/p) = 2/5
q/p = (2/5)*(1/2)
q/p = (2*1)/(5*2)
q/p = 1/5
