12 *12 = 144
Therefore 12^2 = 144
        
                    
             
        
        
        
Answer:
The amount in the account at 12% interest is $3400 and the amount in the second account at 7% interest is $2600
Step-by-step explanation:
Let x be the amount in the account at 12% interest
So, 6000-x is the amount in the second account at 7% interest

First account:
Second account : 
We are given that At the end of the first year he had earned $590 in interest.
So, 
So,the amount in the account at 12% interest is $3400
The amount in the second account at 7% interest =6000-x=6000-3400=2600
Hence the amount in the account at 12% interest is $3400 and the amount in the second account at 7% interest is $2600
 
        
             
        
        
        
60 hundreds means 6000 = 6 thousands;
So, 10 · x = 6000;
x = 600;
600 means 6 hundreds;
Finally, 10 times as many as 6 hundreds is 60 hundreds or 6 thousands.
 
        
             
        
        
        
Answer:
#9: 1.2
#10: 1.25
Step-by-step explanation:
To find the scale factor of the smaller figure to the larger figure, we're going to be dividing the measurements of corresponding edges.

If you wanted to find the scale factor of the larger figure to the smaller figure, you'd do: 
Question #9:
Left edges:  ⇒
 ⇒  = 1.2
 = 1.2
Bottom edges:  ⇒
 ⇒  = 1.2
 = 1.2
<em>(You should get the same number as long as the figures are similar.)</em>
<em />
Question #10:
Bottom edges:  ⇒
 ⇒  = 1.25
 = 1.25
<em>(There are no corresponding edges with measurements that we can compare.)</em>
