Answer: 5.22 seconds
<u>Step-by-step explanation:</u>
t represents time and y represents the height.
Since we want to know when the ball hits the ground, find t when y = 0
Ball 1 starts at a height of 109 --> h = 109
0 = -16t² + 109
16t² = 109
t = 5.22

Answer:
(A) 1/8 x 1/6
Step-by-step explanation:
Division by a number (or fraction) is the same as multiplication by its reciprocal. That is, division by 6 is the same as multiplication by 1/6.
(1/8) ÷ 6 = 1/8 × 1/6

<em>Additional comment</em>
The original division problem can also be formulated as ...
(1/8) ÷ (6/1) . . . . . matches choice D
In order to do this division, you would typically rewrite this to 1/8 × 1/6 (choice A).
Divide by three on both sides then end up with x+2=3 then x=1
