It's D
Step-by-step explanation:
2t - 30() = 20
2t - () = 20
2t - = 20
2t - 6 = 20
2t - 6 + 6 = 20 +6
2t = 26
=
t = 13

Answer:
<h2>
The intensity in decibel is 320 decibel </h2>
Step-by-step explanation:
Given the intensity, or loudness, of a sound measured in decibels (dB), according to the equation where;
I is the intensity of a given sound and
is the threshold of hearing intensity
To get I(dB) when
We will substitute the value of I = into the equation above to have;
Since log10 = 1;
The intensity in decibel is 320 decibel
I would say 17% because your just finding the % that’s goes into 40 and 33
