Answer: D, .1
Step-by-step explanation: 10 marbles and 1 green
50 times she pulled and almost every ten tries she got green meaning there's a high chance of her getting 1 green every 10 tries
Answer:
The answer to the question is
It take for the golf ball hit on Mars to reach the ground 8.284 s longer.
Step-by-step explanation:
To Solve the question, we note that the equation of motion is given to us as
h = -1.9·t² + 26·t
Therefore the height
We compare the above equation with the equation of of motion
S = ut - 0.5×g×t² where u = initial velocity = 26 m/s and - 0.5×g = -1.9
Therefore the acceleration due to gravity om mars = -1.9/-0.5 = 3.8 m/s²
We now have the time taken to maximum height given by
v = u - g·t where v = 0 at maximum height
We therefore have u = g·t → 26 = 3.8×t or t = 26/3.8 = 6.84 seconds
The time taken for ball to hit the ground is 2 × the time to reach maximum height = 2 × 6.84 = 13.684 s
The time longer it takes for the ball on Mars to complete the path up to maximum height and down again is 13.684 s - 5.4 s = 8.284 s.

Answer:
19.6
Step-by-step explanation:
The ratio of brown paint to white paint is, 5:7 or 
so if he bought 14 gallons of white paint we need to figure out:
which we can as it only has one unknown:
5x=14×7
5x=98
x=19.6
So the answer is 19.6
