Answer:

2100

Step-by-step explanation:

In how many ways can a group of 10 people be divided into three groups consisting of 2,3, and 5 people?

First, you need to choose 4 people to fill the first group.

The number of ways is (104) which equals to 210.

Then, pick 3 more people out of the remaining 6 to be in the second group. And then, pick 3 more out of the remaining 3.

However, we need to divide it by 2, since we don’t really care on the order of selection of group.

(63)(33)/2=10

So, there are 210 x 10 = 2100 ways

Answer:

hmmm I read JeremyBrooks answer... I think that it might be different...

i think it is 2520

of the 10 you first choose 2

10 choose 2 = 45 ways

in each of the 45 "chooses" you now

pick a group of 3 of the 8 left

8 choose 3 = that is 56

of the five people left you choose 5

5 choose 5 = 1

so the possibilities are 45*56 * 1 = 2520

the area of a bathroom floor measures 3 yards by 3 yards and each custom tile that makes up the flooring is 1 1/2 square yards.
wel

Using the area, the number of tiles needed to cover the floor is 6.

<h3>What is area?</h3>

The area is the region bounded by the shape of an object.

Therefore, the bathroom floor measures 3 yards by 3yards.

Hence the area of the bathroom floor can be calculated as follows;

area of the bathroom floor = 3 × 3

area of the bathroom floor = 9 yards²

The area of the custom tiles that makes the flooring is 1 1  /2 square yards.

Hence,

number of tiles needed to cover the floor = 9 ÷ 3  /2

number of tiles needed to cover the floor = 9 × 2  / 3

number of tiles needed to cover the floor = 18 / 3

number of tiles needed to cover the floor = 6

What is the elapsed time between 2:16 A.M. and 8:10 P.M.? A. 18 hr. 18 min. B. 17 hr. 54 min. C. 29 hr. 54 min. D. 22 hr. 18 min
Arada [10]
<span>To solve the problem we can subtract the initial time from the final one and keep in mind that from x AM to x PM there are 12 hours. In our case we have: from 2:16 AM to 2:16 PM we get 12 hours. And now we can subtract 2:16 hours or 2*60 + 16 = 136 minutes from 8:10 hours or 8*60 + 10 = 490 minutes. Which gives us 490 - 136 = 354 minutes, or 5 hours and 54 minutes. Plus the other 12, it gives us 17 hours and 54 minutes. So the answer is B.</span>
