There are runners in a race. How many ways can the runners finish first, second, and third? There are nothing different ways that the runners can finish first through . (Type a whole number.)

See Explanation Below

Step-by-step explanation:

Your question seem incomplete as the number of runners is omitted; However, I'll give a general guideline you can follow to solve questions like this

Assume that the number of runner is n;

The first position can be occupied by n persons

The second position can be occupied by n - 1 persons

The third position can be occupied by n - 2 persons

Now, let's assume n is 10

What if there are 50 runners?

You still apply the same logic and procedure;

This means that n = 50

What if there are just 8 runners?

This means that n = 8

So, whatever the number of runner is, just follow the steps I highlighted; you'll get your answer.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

e) none of the above because the measure of angle cba is 101°
