Answer: B and they can play 6 levels
Step-by-step explanation: first solve the mixed fractions
Then solve the factions
Option B:
Solution:
Given sound level = 120 decibel
To find the intensity of a fire alarm:
where 
Step 1: First divide the decibel level by 10.
120 ÷ 10 = 12
Step 2: Use that value in the exponent of the ratio with base 10.
Step 3: Use that power of twelve to find the intensity in Watts per square meter.
Now, do the cross multiplication,
Option B is the correct answer.
Hence .
We know, I = P * R * T /100
Here, P = 10,000
R = 6%
T = 5
Substitute their values into the expression,
I = 10000 * 6 * 5 /100
I = 300000 / 100
I = 300
Final Amount = Initial Amount + Interest Amount
Final Amount = 10,000 + 300 = 10,300
So, your final answer is $10,300
Hope this helps!
