Answer:
90 stamps from Canada, 108 stamps from the United States, and 135 stamps from the Rest of the World
Step-by-step explanation:
Since this is a problem of proportion we can use the Rule of three to solve this. We do this by multiplying the diagonal available values and dividing by the third value in order to get the missing variable, which in this case would be the number of stamps in the other country. Like so...
1.5  <=====>  135 stamps
1.2  <=====>  x  stamps (United States)
(1.2 * 135) / 1.5 = 108 stamps (United States)
1.5  <=====>  135 stamps
1  <=====>  x  stamps (Canada)
(1 * 135) / 1.5 = 90 stamps (Canada)
Finally, we can see that Katie had 90 stamps from Canada, 108 stamps from the United States, and 135 stamps from the Rest of the World. All creating a ratio or 1:1.2:1.5
 
        
             
        
        
        
Y=x².
This is te function of a parabola open upward
the domain is all values of x ={x/x∈z}
        
             
        
        
        
Step-by-step explanation:
To find the formula for the nth term ,
First , find the common difference or common ratio.
Common difference = 

Common ratio = 

The common difference applies to the other given numbers for example :

this proves that it is an arithmetic sequence and the given formula for the nth term of an arithmetic sequence is
T_n =a(n-1)d
Where n = no of terms
a= first term
d= common difference
 
        
             
        
        
        
Answer:  9 i think, i don't know hope i helped :)
 
        
                    
             
        
        
        
The ratio is 5:4:7:9. The reason why they didn't write it together is that the  bananas are written in different form.
