Answer:
5995 hugs
Step-by-step explanation:
This is a combination problem: we want to make groups of two monkeys, where a pair of monkey 1 and 2 is the same pair of monkey 2 and 1 (it is the same hug). So, if the total number of monkeys at the zoo is 110, we have a combination of 110 choose 2:
C(110,2) = 110! / (2! * (110-2)!) = 110 * 109 / 2 = 5995
So the total number of hugs is 5995
The answer is C
The reason: There are two width and two length sides. So, therefore, if you want the fencing to equal 40 feet around the perimeter, 8 · 2 + L · 2 has to = 40.
You would factor 2 out, and you get 2(8 + L) = 40.
Answer:
27 is correct.
Step-by-step explanation:
2^-1(5)^3(7)^4/2^6(5)^-3(7)^3= (5)^6(7)/2^7
