35 because if you half the amount of salads he's eaten (seeing as he eats one burger for every two salads) then the extra one is the first salad in the cycle.
Answer:
The diameter is 13.88 feet.
Step-by-step explanation:
1. The formula for calculate the volume of a sphere is:
![V=\frac{3}{4}(r^{3}\pi)](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B3%7D%7B4%7D%28r%5E%7B3%7D%5Cpi%29)
Where
is the radius.
2. The diameter is:
![D=2r](https://tex.z-dn.net/?f=D%3D2r)
3. So, you must solve for the radius in the first equation:
![r=\sqrt[3]{\frac{4(790.272ft^{3} )}{3\pi}}\\r=6.94ft](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B4%28790.272ft%5E%7B3%7D%20%29%7D%7B3%5Cpi%7D%7D%5C%5Cr%3D6.94ft)
4. Then, the diameter is:
![D=2(6.94ft)\\D=13.88ft](https://tex.z-dn.net/?f=D%3D2%286.94ft%29%5C%5CD%3D13.88ft)
You could convert them into improper fractions first. 7 7/8 should become 63/8 and 3 1/4 should become 13/4. Then, change both fractions so they share a common denominator. I'll use 8.
63/8-26/8 = 37/8, which is then converted into 4 5/8.
Hope that helped you.
Answer:
![7 \times {3}^{n - 1}](https://tex.z-dn.net/?f=7%20%5Ctimes%20%20%7B3%7D%5E%7Bn%20-%201%7D%20)
Step-by-step explanation:
using form:
![a \times {r}^{n - 1}](https://tex.z-dn.net/?f=a%20%5Ctimes%20%20%7Br%7D%5E%7Bn%20-%201%7D%20)
where a: starting number
where r: common ratio (in this case each next term is 3 times previous term)
