A ball is dropped from a height of 8 feet. If every time it bounces, it bounces 60% of its previous height, what is the total di
vladimir1956 [14]

Answer:

<h3>20feet</h3>

Step-by-step explanation:

Initial height of the ball = 8feet

If it bounces 60% of its previous height, its new height will be;

60% of 8

= 60/100 * 8

= 480/100

= 4.8 ft

If it bounces 60% of its current distance, new height will be expressed as;

60% of 4.8

= 0.6 * 4.8

= 2.88

The height of the ball will keep reducing and form a geometric progression of the form 8, 4.8, 2.88...

In order to get the total distance traveled by the ball, we need to calculate the sum to infinity of the sequence;

S∞ = a/1-r where;

a is the first term = 8

r is the common ratio

r = \frac{4.8}{8} = \frac{2.88}{4.8}\\r =  0.6

Substitute into the formula;

S∞ = a/1-r

S∞ = 8/1-0.6

S∞ = 8/0.4

S∞ = 20feet

Hence the total distance traveled by the ball is 20feet

Roll dice and flip coin
scZoUnD [109]
Roll dice and flip coin:
Probability of rolling a cube and getting a 3 = 1/6 .
Probability of flipping a coin and getting HEADS = 1/2 .

Probability of both = (1/6) x (1/2) .
You do the multiplication.

4 blue, 2 green, 6 red
Probability of a blue on the first draw = 4 out of 12 marbles = 1/3 .
Without putting the blue back in ...
Probability of a red on the next draw = 6 out of 11 marbles = 6/11 .

Probability of both = (1/3) x (6/11) .
You do the multiplication.
