Answer is 14
Step by step explanation
The amount is same so
64+8w=92+6w
2w=92-64=28
w=14 => after 14 weeks
The answer is 7 teaspoons for one cup

Answer:
According to the passage, we have the next equation:
![\frac{dV}{dt} = \frac{4}{3}\pi*3*r^{2}*\frac{dr}{dt} = K*(4\pi*r^{2} )](https://tex.z-dn.net/?f=%5Cfrac%7BdV%7D%7Bdt%7D%20%3D%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%2A3%2Ar%5E%7B2%7D%2A%5Cfrac%7Bdr%7D%7Bdt%7D%20%3D%20K%2A%284%5Cpi%2Ar%5E%7B2%7D%20%29)
where "K" is a proportional constant
Leaving at the end with the next equation:
![\frac{dr}{dt} = K](https://tex.z-dn.net/?f=%5Cfrac%7Bdr%7D%7Bdt%7D%20%3D%20K)
Integrating the equation, we have:
![r=K*t+C](https://tex.z-dn.net/?f=r%3DK%2At%2BC)
where "C" is a constant
Then, we have the 2 conditions for the problem:
1) t=0 → r=10
Replacing in the equation, we have C = 10
2) t=5 → r=8
Replacing in the equation, we have K = -0.4
Finally, the time which the snowball will be completely melted will be when r = 0. So replacing in the equation
![0=-0.4*t+10](https://tex.z-dn.net/?f=0%3D-0.4%2At%2B10)
t = 25 minutes
Answer:
25.67
Step-by-step explanation:
10 to the power of 4 is 10,000.
That means we have to do 10,000 divided by 389.5, getting 25.67
