Answer:
I think it would be 35 inches tall.
Step-by-step explanation:
Because it's growing at a rate of 2 inches per week for 10 weeks, that's 20 inches plus the 15 it already had.
Answer:
Answer choice A
Step-by-step explanation:
For the first letter, there are 26 options, as there are for the second and third letter. For each of the three numbers, there are 10 digits to choose from. Therefore, 26*26*26*10*10*10=17,576,000, or answer choice A. Hope this helps!

Yes, I agree
Step-by-step explanation:
See attachments for cone
Cone A
![h = 2r](https://tex.z-dn.net/?f=h%20%3D%202r)
Cone B
R = 2r
![h=r](https://tex.z-dn.net/?f=h%3Dr)
The volume of a cone is
![V = \frac{1}{3}\pi r^2h](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2h)
For cone A, we have:
![V = \frac{1}{3}\pi r^2*2r](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2%2A2r)
![V_A = \frac{2}{3}\pi r^3](https://tex.z-dn.net/?f=V_A%20%3D%20%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r%5E3)
For cone B, we have:
![V = \frac{1}{3}\pi *(2r)^2 * r](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20%2A%282r%29%5E2%20%2A%20r)
![V = \frac{1}{3}\pi *4r^2 * r](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20%2A4r%5E2%20%2A%20r)
![V_B = \frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=V_B%20%3D%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
So, we have:
![V_B = 2 * \frac{2}{3}\pi r^3](https://tex.z-dn.net/?f=V_B%20%3D%202%20%2A%20%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r%5E3)
Substitute ![V_A = \frac{2}{3}\pi r^3](https://tex.z-dn.net/?f=V_A%20%3D%20%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r%5E3)
![V_B = 2 * V_A](https://tex.z-dn.net/?f=V_B%20%3D%202%20%2A%20V_A)
Make VA the subject
![V_A = \frac{1}{2}V_B](https://tex.z-dn.net/?f=V_A%20%3D%20%5Cfrac%7B1%7D%7B2%7DV_B)
Hence, I agree with Ahmad
