For this case we have the following equation:

Where,
I: <span>the intensity of a given sound
I0: </span><span> the threshold of a hearing intensity
</span>Substituting values in the given equation we have:
<span />

<span />Rewriting the equation we have:
<span />

<span />Then, by properties of logarithm we have:
<span />

<span />Finally we have:
<span />

<span />
Answer:
T<span />
he intensity, in decibles, [I(dB)], when I=10^8(I0) is:
D.80
Answer:
360 calories
Step-by-step explanation:
you divide 3 by 3/4ths and you get 4. You then multiply 90 by 4 and the solution is 360 calories.
Volume = (4/3) * PI() * r^3
radius^3 = Volume / (4/3) * PI()
radius^3 = 904.78 /
