Answer:
The linear speed in which Darlene is traveling is 24.74 miles per hour. 
Step-by-step explanation:
The wheel experiments rolling, which is a combination of translation and rotation. The point where linear speed happens is located at geometrical center of the wheel and instantaneous center of rotation is located at the point of contact between wheel and ground. The linear speed ( ), measured in inches per second, is defined by following expression:
), measured in inches per second, is defined by following expression:
 (1)
 (1)
Where:
 - Radius of the wheel, measured in inches.
 - Radius of the wheel, measured in inches.
 - Angular speed, measured in radians per second.
 - Angular speed, measured in radians per second.
If we know that  and
 and  , then the linear speed, measured in miles per hour, in which Darlene is traveling is:
, then the linear speed, measured in miles per hour, in which Darlene is traveling is:


The linear speed in which Darlene is traveling is 24.74 miles per hour. 
 
        
             
        
        
        
30% of 40 = 0.30(40) = 12......so 12 tables seat 4 people per table = 12 x 4 = 48 seats.......tables remaining seat 22 people (22 seats).
48 + 22 = 70 seats total
        
                    
             
        
        
        
Answer:
A. The point (0,0) shows that the cost is $0 for 0 kg of cashews.
 
C. The point (2,60) shows that it cost $60 for 2 kg of cashews.
B. The constant of proportionality for this graph is 30.

Answer:
Rotation - Twists the shape 
Reflection - Flips the shape 
Translation - Slides a shape 
Dilation - Enlarge or reduces a shape
Congruent - Same shape same size 
Rigid Motion - type of transformation that  creates congruent figures
Hope this helped. I apologize if any of them are wrong..
