The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as
ere'o - 10
and is the least intense sound a human ear can hear. What is the approximate loudness of a
dinner conversation with a sound intensity of 10-7?
O -58 Db
O -50 Db
O 9 Db
O 50 Db

represent the minimum audible intensity by the humans

represent the intensity for the dinner conversation

And replacing this into the formula we got:

So then the best answer for this case would be:

O 50 Db

Step-by-step explanation:

For this case we can use the following equation for decibels:

Where:

represent the minimum audible intensity by the humans

represent the intensity for the dinner conversation

And replacing this into the formula we got:

So then the best answer for this case would be:

O 50 Db

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
