1 answer:
Answer:
Linear speed : 2.09 in/s
Angular speed in RPM: 2.5 RPM
Angular speed in rad/s: 
Step-by-step explanation:
Given:
Radius, r = 8 inches
Angular speed = 15°/s
Let's convert the angular speed to radian/sec using the formula :

To find the angular speed in RPM.
In rad/second we have:

Convert to minute, we have:

Number of revolutions per minute =

To find the linear speed:
Let's use the formula.
V = rw
Where,
r = 8 inches
w = 

= 2.09 in/sec.

Answer:
x= 15 so the c) is right
Step-by-step explanation:
We can do it like:
3(2x + 5) = 3x + 4x
or 6x + 15 = 7x
-6x+ 6x +15 = -6x+ 7x
or 15 = x
The solution is 15
