Answer:
(10,2)(20,4)(30,6)(40,8)
Step-by-step explanation:
In each bracket the first digit divided by the second is equal to 5
10÷2=5
20÷4=5
30÷6=5
40÷8=5
 
        
             
        
        
        
Answer:
DBA =110 degree
Step-by-step explanation:
angle DBA is central angle 
central angle = arc angle = 110 degree
 
        
                    
             
        
        
        
Based on the given problem above, if we analyze it, we are going to look for the graph which with coordinates (0,6) which represents starting out with 6 gallons, and ending at (4,0). So, the graph that best represents this situation would be the first graph on the top left. Hope this answers your question. Have a great day!
