Answer:
1.5 bags
Step-by-step explanation:
They each had 900 dollars, so when combined they have 1800 dollars. They bought a movie ticket for 1200 dollars, so they now have 1800-1200=600 dollars.
600/2 is 300. Each bag of popcorn costs 200 dollars. So they could each buy 1.5 bags of popcorn.
Answer:
(a) t = 7 sec approximately; (b) t = 6 sec
Step-by-step explanation:
(a) Set h(t)= -16(t-3)^2 + 288 = 0 and solve for t:
16(t-3)^2 = 288
After simplification, this becomes (t - 3)^2 = 18, or t - 3 = ±3√2.
Because t can be only zero or positive, t = 3 + 3√2 = 7 seconds
(b) Solve h(t)= -16(t-3)^2 + 288 = 150:
-16(t-3)^2 = - 162
or (t - 3)^2 = 10.125, or
t - 3 = ±3.18, or, finally, t = 6.18 sec (discard t = -0.18 sec)
