Step-by-step explanation:
 
        
             
        
        
        
1.53 rounded to the nearest tenth is 1.5
        
                    
             
        
        
        
The effective rate is calculated in the following way:

where r is the effective annual rate, i the interest rate, and n the number of compounding periods per year (for example, 12 for monthly compounding).

Answer:
Ratio 2:3 I think :)
Step-by-step explanation:
 
        
             
        
        
        
Firstly, $3.99 × 5 = $19.95 
Second, $2.75 × 5 = $13.75
Third, $2.70 × 3 = $8.1 (Since it is just $8.1 that won't make sense so we'd add a 0 so It's $8.10.)
Then we do the last one which is 13 × $0.89 = $11.57.
So now since we are done multiplying we can add it all up.
The answer is $53.37 when we finish adding it up. 
and I don't know what A number sentence is sorry :(
