Answer:
Total number of orders = 77,520
Step-by-step explanation:
Given:
Number of students on team = 20
Number of students on the starting line =9
Find:
Total number of orders
Computation:
Total number of orders = 20! / [20 - 7]!(7!)
Total number of orders = 20! / [13]!(7!)
Total number of orders = [20 x 19 x 18 x 17 x 16 x 15 x 14] / [7 x 6 x 5 x 4 x 3 x 2 x 1]
Total number of orders = 77,520

Using the quadratic formula the 2 zeros of the function (there have to be 2 cuz it's a quadratic) are x = -1/2 and -5 1/2
If you would like to know how many days did it take Kim to read part 1 of the book, you can calculate this using the following steps:
d ... the number of days
380 pages - 20 pages * d = 160 pages
380 - 20 * d = 160
380 - 160 = 20 * d
220 = 20 * d
d = 220 / 20
d = 11 days
The correct result would be 11 days.
