Answer:

Below.

Step-by-step explanation:

2 3/5 + 8 1/2

= 2 + 8 + 3/5 + 1/2

= 10 + 3/5 + 1/2

The LCM of 5 and 2 is 10 so we get:

10 + 6/10 + 5/10

= 10 + 11/10

= 10 + 1 1/10

= 11 1/10 feet.

1) A ball is dropped from a height of 50 feet. How long after it is dropped will it reach a height of 18 feet?

Nookie1986 [14]

Answer: 1.41 seconds

Step-by-step explanation:

The problem gives the initial velocity by saying "dropped." This indicates a velocity of zero. Acceleration can also be found because the object is in free fall. It would experience the acceleration of gravity. We can use the kinematic equation:

$(y_f-y_i)=V_it+\frac{1}{2}at^2$

The velocity term completely cancels because the object was dropped with an initial velocity of 0.

$(18-50)=\frac{1}{2} (32.17)t^2\\$

$-32=-16.085t^2\\t=\sqrt{1.989} =1.41s$
