Any multiples of 4.5:1.5 would work because being proportional just depends on whether you can reduce to get the same answer of the first triangle. You could do anything like 9m and 3m or 27m and 9m
        
             
        
        
        
Answer:
26 years
Step-by-step explanation:
Given:
The mean age of 9 women = 27 years old
The mean age of 7 men = 25 years old
Question asked:
What is the mean age (nearest year) of all the people in the office?
solution:
By using, mean = sum of observations divided by number of entities
The mean age of 9 women = 27 years old
 =
 = 
 
 
The mean age of 7 men = 25 years old
 =
 = 

Total sum of ages of men and women in the office = 243 + 175 
                                                                                      = 418 years
Total number of people in the office = 9 women + 7 men = 16
The mean age of all the people in the office = Total sum of ages of men and women in the office divided by Total number of people in the office 
                                                                          = 
Therefore,  the mean age (nearest year) of all the people in the office = 26 years

Answer:
The enrollment after 5 years is 10,724 
Step-by-step explanation:
Generally, we can have the depreciation formula written as follows;
A = P(1 - r)^t
A is the number of enrollment in after a certain number of years t
P is the initial population which is 13,500
r is the rate of depreciation which is 4.5% = 4.5/100 = 0.045
t = 5 years 
Substituting these values, we have it that;
A = 13,500(1-0.045)^5
A = 10,723.84
