I'm assuming we can say each Democrat, Republican, and Independent are the same element.

Since there are 12 seats, we can seat them in 12! different ways, assuming straight line.
\text{Total(no restrictions): } 12!

However, the four democrats are the same element, since we only care about the different parties. Using this same logic, the 5 Republicans can swap without us knowing and the 3 Independents, as well.

Thus, we've overcounted by a factor of 4! 5! 3!, because each element are identical.

To counter this, we divide by the number of elements repeated:
\text{Total ways: } \frac{12!}{4!5!3!} = 27,720

Can I get some help with 4) and 5) plz
bulgar [2K]
Plan 1 is the best choice because plan 2 would be an extra $120.00 more for the year.

No because Pam is reading 42 pages every hour so in 5 hours she would have only read 210 pages. Zack is reading 45 pages in an hour so he would finish just under 5 hours.

Sarah's craft project uses pieces of yarn that are 1/8 yard long. She has a piece of yarn that is 3 yards long. How many 1/8 yar
Verdich [7]
If she used all of her yarn, she'd have 24 pieces. If she wanted 1.25 left, she'd have ten less because 24 • .125 = 8, and 1/4 of eight = 2, and 2 + 8 = 10.

So she'd have 14 pieces.
