C) find the least common denominators
<h3>
Answer: 10,080</h3>
Explanation:
There are 8 letters so there are 8! = 8*7*6*5*4*3*2*1 = 40,320 permutations of those letters. However, the letters "O" and "L" show up twice each, so we must divide by 2! = 2*1 = 2 for each instance this happens.
So,
(8!)/(2!*2!) = (40,320)/(2*2) = (40,320)/4 = 10,080
is the number of ways to arrange the letters of "football".
The reason we divide by 2 for each instance of a duplicate letter is because we can't tell the difference between the two "O"s or the two "L"s. If there was a way to distinguish between them, then we wouldnt have to divide by 2.
Answer:
A. 2
Step-by-step explanation:
The common ratio between the terms listed is 2. Each term is being multiplied by 2, so to find the first term, you have to divide the first term listed by 2.
4/2 = 2
Answer:
4 2/7
Step-by-step explanation:
5/((8-1)/6)
5/(7/6)
(5/1)/(7/6)=(5/1)*(6/7)
=30/7
=4 2/7
Answer: 49
Step-by-step explanation:
251-6=245
245/5=49
