In a billiards game, Pete hits a ball that is 20in. 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 proportion can be used to find the distance, x, the ball traveled after it bounced off the wall to get to the ending position? CHECK ALL THAT APPLY!

A 20/16 = x/34

B 20/16 = 34/x

C 16/20 = x/34

D 34/x = 20/16

The answer is 10,000,000 because u have to do 10x10x10x10x10x10x10


So basically I did the most easiest way possible with is multiply 1 and 1 and then add the zero and I got 10 so if u add the zeros up 6 more times then we get 10 million or 10,000,000.

Answer:

1. n + 8 = 10

2. \frac{n}{12}= 10

3. 8n - 6 = 34

4. 3(n + 12) = 45

5. No

6. Yes

Step-by-step explanation:

(only for questions 5 and 6)

5. If you substitute in y = 1, you get 1 * 49 = 0 or 49 = 0 which is not true.

6. If you substitute in b = 8, you get:

5(8-3)= 25\\5(5) = 25\\25 = 25

this is true.

A gear with a diameter of 12.0 inches makes 35 revolutions every three minutes. Find the linear and angular velocities of a poin
alina1380 [7]

Answer:

Angular velocity: \omega = \frac{7\pi}{18} \,\frac{rad}{s} (1.222\,\frac{rad}{s})

Linear velocity: v = \frac{14\pi}{3}\,\frac{m}{s} (14.661\,\frac{m}{s})

Step-by-step explanation:

The gear experiments a pure rotation with axis passing through its center, the angular (\omega), in radians per second, and linear velocities (v), in inches per second, of a point on the outer edge of the element are, respectively:

\omega = \frac{2\pi}{60}\cdot \dot n (1)

v = R\cdot \omega (2)

Where:

\dot n - Rotation rate, in revolutions per minute.

R - Radius of the gear, in inches.

If we know that \dot n = \frac{35}{3}\,\frac{rev}{min} and R = 12\,in, then the linear and angular velocities of the gear are, respectively:

\omega = \frac{2\pi}{60}\cdot \dot n

\omega = \frac{7\pi}{18} \,\frac{rad}{s} (1.222\,\frac{rad}{s})

v = R\cdot \omega

v = \frac{14\pi}{3}\,\frac{m}{s} (14.661\,\frac{m}{s})
