Answer:

The answer is \frac{646,449}{68.3} =9,464.85

Step-by-step explanation:

In order to determine the unit rate, we have to know about rates.

In any "rate", the number is representing the fraction of two measures. For example in physics, the velocity is the rate of distance per time, where we divide the distance measure by the time measure.

In this case, we have two measures:

  1. people.
  2. square mile.

So, the rate that relates both measures is:

\frac{people}{square mile} \\\frac{646,449}{68.3}\\ 9,464.85

Finally the unit rate is:

\frac{646,449}{68.3} =9,464.85

Answer:

1

One half can only fit into 2/3 one time because because 1/2 plus one half is 1 whole. 2/3 is not one whole so 1/2 cannot go into it more than once.

Twenty people apply for 5 job openings as teacher assistants. How many different groups of people can be hired?
iVinArrow [24]

Answer:

15504 different groups

Step-by-step explanation:

We have a total of 20 people, and we want to know how many groups of 5 people we can make, where the order of the people inside the group doesn't matter, so we can solve this question calculating the combination of 20 choose 5.

The formula for combination is:

C(n, p) = n! / (p! * (n-p)!)

In this case, we have n = 20 and p = 5, so:

C(20, 5) = 20! / (5! * 15!) = 20*19*18*17*16 / (5*4*3*2) = 15504

So we have 15504 different groups.
