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:
15 and 20
Step-by-step explanation:
When dividing 88 by 5 we wil have;
88/5
= 17 3/5
= 17 + 0.6
= 17.6
So we are to find the two numbers that 17.6 falls in between
From the given option 17.6 falls between 15 and 20. Hence the required numbers are 15 and 20
