Answer:
50
Step-by-step explanation:
so half a dollar is $0.50. We multiply by 9, which gives you $4.50. But the customer gave $5, so they would get $0.50 back. 
 
        
                    
             
        
        
        
Answer:
t=13
Step-by-step explanation:
the ratio of the shorter sides is t/4 and the ratio of the longer sides is 26/8 so t=26×4/8=104/8=13
 
        
                    
             
        
        
        
Answer:
A. the slope value is 1/4
B. 0
C. y = 1/4x 
Step-by-step explanation:
A: the slope can be calculated with the formula 

m is the slope
(x1, y1) is your first coordinate point (any point will work)
(x2, y2) is your second coordinate point (any point will work)
Plug in your values, in this case I chose (0,0) and (4,1) as the two coordinates:

B: the y-intercept is the y-coordinate of where the graph touches the y-axis and in this case the coordinate is (0,0) where the y coordinate is 0.
C: 
the equation of the graph is y = mx + b. 
m is the slope = 1/4
b is the y-intercept = 0
Therefore the equation is y = 1/4x 
 
        
             
        
        
        
8 x 6 = 42 add two zeros so 4200
 
        
             
        
        
        
the next term is 1 because 64 divide by 16 is 4 which means the geometric sequence is decreasing by 4
