The intensity of sound is measured on the decibel scale, dB. The equation
dB 10 log I represents the decibel level, where I is the ratio of the sound to
the human hearing threshold. A noise registers a decibel level of 29. What is the
value of I? Round to the nearest whole number.

A) 42071
B) 18
C) 89
D) 794

Respuesta :

The answe is b 18 because c x x = y

Answer: D) 794

Step-by-step explanation:

[tex]10lgI=29[/tex]

Divide both parts of the equation by 10:

[tex]lgI=2.9\\\\I=10^{2.9}\\\\I\approx794[/tex]
