The number of square feet of the carpet is the area of the carpet

The number of square feet of outdoor carpet is 32 feet

<h3>How to determine the number of square feet</h3>

To do this, we simply divide the carpet to regular shapes.

The outdoor carpet can be divided to the following shapes from top to bottom

Rectangle of 4 ft by 2 ft
Rectangle of 6 ft by 2 ft
Rectangle of 6 ft by 2 ft

So, the area of the outdoor carpet is:

Area = 4 * 2 + 6 * 2 + 6 * 2

This gives

Area = 32

Hence, the number of square feet of outdoor carpet is 32 feet

Suppose you have 5 riders and 5 horses, and you want to pair them off so that every rider is assigned one horse (and no horse is

maw [93]

There are 120 ways in which 5 riders and 5 horses can be arranged.

We have,

5 riders and 5 horses,

Now,

We know that,

Now,

Using the arrangement formula of Permutation,

i.e.

The total number of ways $^nN_r = \frac{n!}{(n-r)!}$ ,

So,

For n = 5,

And,

r = 5

As we have,

n = r,

So,

Now,

Using the above-mentioned formula of arrangement,

i.e.

The total number of ways $^nN_r = \frac{n!}{(n-r)!}$ ,

Now,

Substituting values,

We get,

$^5N_5 = \frac{5!}{(5-5)!}$

We get,

The total number of ways of arrangement = 5! = 5 × 4 × 3 × 2 × 1 = 120,

So,

There are 120 ways to arrange horses for riders.

Hence we can say that there are 120 ways in which 5 riders and 5 horses can be arranged.

Solve the inequality and find the solution set. y-6 ≥12

Furkat [3]

The first step for solving this inequality is to move the constant to the right side by adding its opposites to both sides. This will look like the following:
y - 6 + 6 ≥ 12 + 6
Eliminate the opposites on the left side.
y ≥ 12 + 6
Lastly,, add the numbers on the right side together to get your final answer.
y ≥ 18
