Answer:
48 inches
or 
0.8 minutes
Step-by-step explanation:
To find the unit rate of inches per hour, divide 144 by 3. 
144÷3=48
You don't need to round because there are no decimals. 
To find the time to braid 1 inch, first multiply 3 by 60 (because there are 60 minutes in 1 hour). 
3×60=180
Then divide 144 by 180. 
144÷180= 0.8
You don't need to round because there are no thousandths. 
 
        
             
        
        
        
well, since we know that there are 180° in π radians, how many degrees will it be in 345°?

 
        
             
        
        
        
Hello,
(tg(x))'=1/cos²(x)
(arcsin(x))'=1/√(1-x²)
cos²(arcsin(x))=1-sin²(arcsin(x))=1-x²
 
 
        
        
        
The probability is 50% or half or 1/2
