195 Campers
8:7 = Boys: Girls
8/15 : 7/15
8/15*195 = 104
7/15*195= 91
Therefore, there are 104 boys and 91 girls.

Answer: So you have 195 campers, and suppose that the ratio of 8:7 is the ratio of boys to girls. This number means that there are 8 boys for each 7 girls.

if we multiply 7 and 8 for the same number x of pairs, and think that the sum of all boys and girls must be equal to 195, we get that

x*7 + x*8 = 195

x*15 = 195

x = 195/15 = 13

so we have 13 pairs of 8 boys and 7 girls.

and the total of boys is 13*8 = 104

and the total of girls is 13*7 = 91

In a bike race Tim rode 7 1/4 miles his teammate Bill rode 8 7/8 how many miles did they ride in all

Minchanka [31]

So you add the miles together and you would get 16 1/8 you add the whole numbers and get 15. you have to change the denominator to equal the same thing so it would change to 2/8 instead of 1/4 and then add it up and get 9/8 so you add a whole number and left with 1/8 and the answer is 16 1/8

A committee consists of 8 men and 11 women. In how many ways can a subcommittee of 3 men and 5 women be chosen?

PIT_PIT [208]

Answer:

25872 ways

Step-by-step explanation:

We're choosing 5 women from a group of 11 and 3 men from a group of 8. We don't care about what order they are picked and so we'll use the combination formula, which is:

n!/(k!)(n-k)! with n as population and k as picks.

We'll multiply the results together. (8! / (3!)(8-3)!) * (11! / (5!)(11-5)!)

That equals: (8! / (3!)(5!) ) * (11! / (5!)(6!)) = 40320/(6x120) * 39916800/ (120x720)

56 * 462 = 25872
