In mathematics, a set A is a subset of a set B, or equivalently B is a superset of A, if A is "contained" inside B. I belive the correct answer from the choices listed above is the second option. It is the set {5, 6, 7} that is a subset of <span> {1, 3, 5, 7, 9}. Hope this answers the question</span>
They basically make a profit of $2.85. Because $9.95 - $7.10 = $2.85.
To break even you would have to sell 4000 footballs. Because 11,400 / 2.85 = 4000.
<em>Factors and multiples are related by multiplication.</em>

Explanation:</h2>
When you multiply numbers together to find a number, say, n, then those numbers are called factors of n. For instance:

On the other hand, a multiple, say, n, results when multiplying a number by an integer. For instance:

So
is multiple of

Answer:
I believe its B.
Step-by-step explanation:
What you can do is start with the key details in it... the main ones are that the bacteria grows every 30 minutes, you start with 1 bacteria, and the end time is 180 minutes. Basically you know that 3 goes into 18 6 times so 30 goes into 180 6 times which means that if you started with 1 bacteria you will end up with 7. Understand?
