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

Please answer I’ll rate brainlyest
dimulka [17.4K]

Answer:

49.1%

Step-by-step explanation:

From the table, the number of male voters who are registered Democrats is given as 600. Moreover, the total number of male voters is given as 1222. Therefore, the probability that a randomly chosen male voter is a registered Democrat will be calculated as;

number of male voters who are registered Democrats /  total number of male voters

600/1222 = 0.491

As a percentage this becomes;

0.491 * 100 = 49.1%
