Answer:
group b
Step-by-step explanation:
because group a got 7.5 kg of berries in total and group b got 8.25 and 8.25>7,5
 
        
             
        
        
        
Answer:
19)$33
20)1/3 or if u make like denominators 1/6 because they already did 3/6 and 2/6 leaving 1/6
21)0.40
22)0.6
23)0.80
24)0.70
 
        
             
        
        
        
For this case we have a function of the form:

 Where,
 A: initial population of bacteria
 b: growth rate
 x: number of hours
 Since the diameter is double every hour, then:
 
 We must now look for the value of A.
 To do this, we evaluate an ordered pair of the graph:
 For (1, 2):
 
 Clearing A we have:
 
 
 Then, the function is given by:

 For after 9 hours we have:
 
 Answer:
 the diameter of the bacteria after 9 hours is:
