Answer: 3,140 radians per minute.
Step-by-step explanation:
We know that the wheel does 500 revolutions per minute.
This is called the frequency of the wheel, and this is written as:
f = 500 rev/min = 500 RPM
The angular speed (or Angular velocity) is written as
ω = 2*pi*f 
And this quantity is in radians/unit of time.
where pi = 3.14 
then:
ω = 2*3.14*500 (rev/min)*(rad/rev) = 3,140 rad/min
This means that the angular velocity  (or angular speed) is 3,140 radians per minute.
 
        
                    
             
        
        
        
Answer:
 8
Step-by-step explanation:
For the smallest possible length, this has to be one of the shorter sides. Let the length of this side be x.
So, by the triangle inequality theorem, 1+x>8, which means x>7.
So, the smallest possible whole number length is 8.

Answer:
X = 42
Step-by-step explanation:
2x + 9 = 93
move the constant right
2x = 93 - 9 
2x = 84 divide both sides 
X = 42
