Answer:
The answer to your question is 90 dB
Step-by-step explanation:
Data
I = 10⁻³
I⁰ = 10⁻¹²
Formula
      Loudness = 10log ( )
)
Process
1.- To solve this problem, just substitute the values in the equation and do the operations.
2.- Substitution
      Loudness = 10 log  
 
3.- Simplify
       Loudness = 10log (1 x 10⁹)
       Loudness = 10(9)
       Loudness = 90
 
 
        
             
        
        
        
Answer:
4/10 : 1/25 
4/10 / 1/25 = 4/10 x 25/1 = 100/10 = 10. 
10 can also be written as 10:1, so A is correct.
