The radius of the balloon given the information in the question is 8.98cm.
<h3>What is the radius of the balloon?</h3>
The first step is to determine the volum of the balloon.
Volume = 81π cm^3 x 12 = 972π cm^3
Now, determine the radius using this formula:
∛[Volume / (4/3π )]
∛[972π cm^3/ (4/3π )] = 8.98cm
Here is the complete question:
Andy is blowing up a spherically shaped balloon. If he is able to blow 81π cm^3 of air with every breath, it takes him 12 breaths to fully inflate the balloon. What is the radius of the balloon?

So the growth factor is the base of the exponential term, so the base of y = 34 * 4^x is 4.
the initial amount is the amount at x = 0
y = 15 * 3^xy = 15 * 3^0y = 15 * 1y = 15 is the initial amount
the decay factor of y=17×0.2^x is same as the growth factor, it is 0.2
Answer:
<u><em>x = 16</em></u>
Step-by-step explanation:
<em>(x + 1)² = (x - 3)² + 120</em>
<em>x² + 2x + 1 = x² - 6x + 9 + 120</em>
<em>8x = 128</em>
<em>x = 16</em>
10^6 = 1,000,000
2^8 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 = 256
5^8 = 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 = <span>390,625
1,000,000/256 * 390,625 = </span><span><span>1525878906.25</span>
0.4^7 = </span><span>0.0016384
So, I think you copied it incorrectly.

Answer:
77
Step-by-step explanation:
If the probability of choosing a red marble is 11/12, then 11/12 of the marbles in the bag must be red. Therefore, the number of red marbles is 84*11/12=7*11=77 marbles. Hope this helps!
