For this case, the first thing you should do is observe the graph.
We have that the x-axis represents the intensity of the sound.
The y-axis represents the measure in decibels.
We have then:
For x = 500 the value of y is y = 28
Answer:
The decibel measurement for the quiet room is:

Could you show the book please
Answer:
B
Step-by-step explanation:
Since r and s are parallel lines, then
The angle adjacent to 1 is corresponding to 158 and are congruent, thus
adjacent angle to 1 = 158°
1 and 158° are adjacent and supplementary, so
∠ 1 + 158° = 180° ( subtract 158° from both sides )
∠ 1 = 22° → B
