the answer is 11.
use BEDMAS, and calculate the equation inside the brackets (answer to that is 44/15)
then divide it by 4/15 and you get 11
Answer: 138 calories.
Step-by-step explanation:
If the circumference of a circle is changed from 9 cm to 3 cm, then the diameter decreases by a factor of 3.
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 />

Answer:
T<span />
he intensity, in decibles, [I(dB)], when I=10^8(I0) is:
D.80
