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:
The radius is half the diameter, so the radius is 14/2 = 7 inches
Now, finding the volume, we have:
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):

Answer:
473 Tumips
Step-by-step explanation:
for every 1 potato there is 1 tumip; the numbers should always be equal
<span>A tree must be connected by definition. This means that there can be no vertices of degree 0 in a tree.
Assume for contradiction that we have v vertices and that v - 1 have degree at least degree two. Then we know that the sum of the degrees of the vertices is at least 1 + 2(v-1) which is equal to 2v - 1. Therefore we know that the number of edges must be at least v- 1/2 . But this is impossible because a tree must have exactly v - 1 edges.
Thus we have shown by contradiction that every tree has at least two vertices.</span>
