Answer:
4
Step-by-step explanation:
The ratio of carrots to cucumber is 1:3.
The sum of their fewest amount is 4
 
        
                    
             
        
        
        
4+7=11
11/2=5.5 
round to the nearst whole number
        
             
        
        
        
Answer: 105
Explanation: 
60% + 10% = 70% = yellow and green
30% = red
350/10 = 35 x 3 = 105
        
             
        
        
        
1. ratio = 2 c of dressing / 4 lb of vegetables
Use two variables: d for the number of c of dressing and v for the number of pounds of vegetables.
Then d / v = 2/4 = 1/2 => d = v/2
Now you can make a table
v     d   
2    1
4    2
6    3
8    2
And you can draw a line for the points (2,1); (4,2); (6,3), (8,4) ... the slope of the graph is the ratio = 1/2
b) I already did it above as part ot the explanation: d/v = 1/2
