In a billiards game, pete hits a ball that is 20 in. from a wall. the ball travels 34 in. until it hits the wall and bounces to a position that is 16 in. from the wall. what is the distance, x, the ball traveled after it bounced off the wall to get to the ending position? enter your answer, as a decimal, in the box.

Refer to the attached image,

Peter hits a ball that is 20 inch from a wall means AB=20 in

A ball travels 34 in until it hits the wall means AC=34 in

It bounces back to a position means CD = 'x' in (Say)

It bounces back to CD which is 16 in from the wall means DE=16 in

We have to calculate the value of 'x'.

Since, ball is reflected from point C. By law of reflection which states the angle of reflection is equal to the angle of incidence.

So, = y degrees (say)

Since angles BCF and FCE are right angles.

So, (equation 1)

Now, in triangle ABC and CDE

(Each angle is right angle)

(From equation 1)

Therefore, triangle ABC is similar to triangle DEC by AA similarity.

So, the ratio of corresponding sides are equal.

Substituting the values,

x = 27.2 in

Therefore, the distance, x, the ball traveled after it bounced off the wall to get to the ending position is 27.2 in

27.2

Step-by-step explanation:

took the test and it was the correct answer

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
