Answer:
4 sec
Step-by-step explanation:
let y = 0 which is the height when the rocket hits the ground
-3t^2 + 6t + 24 = 0
-3(t^2 - 2t - 8) = 0
-3(t - 4)(t + 2) = 0
t = 4 or t = -2
time cannot be negative, so t = 4 sec
11x+2 = 9x+6. Subtract 2 from both sides. 11x = 9x+6. subtract 9x from both sides. 2x = 4, divide both sides by 2. x = 2. Substitute the x with 2 and check to see it it works. The numbers should equal each other.
6m + 6m + 15m + 15m = 42m
no 40m will not be enough
Answer:
1/2
Step-by-step explanation:prime numbers ={2,3,5,7}
likelihood of prime numbers =number of prime numbers /all numbers
=4/8 , 4 divides itself once and 4 divides 8 twice.
=1/2
