Answer:
Tyler should buy 2 goldfishes for his fish tank,
Step-by-step explanation:
First let's find the volume of the sphere, using the following equation:
![Volume = (4/3) * \pi * radius^3](https://tex.z-dn.net/?f=Volume%20%3D%20%284%2F3%29%20%2A%20%5Cpi%20%2A%20radius%5E3)
The radius is half the diameter, so the radius is 14/2 = 7 inches
Now, finding the volume, we have:
![Volume = (4/3) * \pi * 7^3](https://tex.z-dn.net/?f=Volume%20%3D%20%284%2F3%29%20%2A%20%5Cpi%20%2A%207%5E3)
![Volume = 1436.75\ in^3](https://tex.z-dn.net/?f=Volume%20%3D%201436.75%5C%20in%5E3)
Now, we know that we need to have 1 goldfish for every 693 in3 of water, so to find the number of goldfishes, we just need to divide the volume of the sphere by 693 (and round down the result if needed):
![Number\ of\ goldfishes = 1436.75 / 693 = 2.07 = 2\ goldfishes](https://tex.z-dn.net/?f=Number%5C%20of%5C%20goldfishes%20%3D%201436.75%20%2F%20693%20%3D%202.07%20%3D%202%5C%20goldfishes)
Tyler should buy 2 goldfishes for his fish tank,
Answer:
6
Step-by-step explanation:
5y + 2 +2y + 3 = 12 - 15
7y + 5 = 12y - 15
7y + 20 = 12y
20 = 5

Answer:
The answer is 94
Step-by-step explanation:
divide 7/10 because thats the fraction = 0.7
divide 65.8 by 0.7
to get 94
to check
multiply 94 by 0.7
