Answer:

840

Step-by-step explanation:

Given

$DJs = 7$

$To\ pick = 4$

Required

Determine the number of rankings

The term "ranking" as used in this question implies permutation and the required is calculated using:

$^nP_r = \frac{n!}{(n-r)!}$

Where

$n = 7$

$r = 4$

So:

$^nP_r = \frac{n!}{(n-r)!}$

$^7P_4 = \frac{7!}{(7-4)!}$

$^7P_4 = \frac{7!}{3!}$

$^7P_4 = \frac{7 * 6 * 5 * 4 * 3!}{3!}$

$^7P_4 = 7 * 6 * 5 * 4$

$^7P_4 = 840$

<em>Hence, number of ranking is 840</em>

A park is in the shape of a rectangle. The park is 5/8 mile long and 2/3 mile wide. What is the area of the park?

Elenna [48]

To find the area of a rectangle, you times the length and width together.
So in this case,
5/8 x 2/3 = 10/24.
This can be simplified to 5/12
