Find the area of the polygon
Rom4ik [11]

Answer:

Step-by-step explanation:

So the area of a cube is a²

This means that:

2² = 4cm²

So the area of a triangle is (b*h)/2

This means that:

(3*2)/2 =

6/2 = 3cm²

4cm² + 3cm² = 7cm²

Cathy and iris are planning trips to nine countries this year. There are 13 countries they would like to visit. They are decidin
Goshia [24]

Cathy and Iris have 259,459,200 ways to skip countries.

Data;

  • Number of countries they are planning to visit = 9
  • Number of countries they would like to visit = 13

<h3>Combination</h3>

To solve this problem, we would have to use a mathematical procedure known as combination.

Let us calculate the number of countries that would have to skip.

13 - 9 = 4

To decide which country they have to skip, it would be 4 out of 13.

x = ^1^3C_4 = \frac{13!}{4!}

Let's solve this

\frac{13!}{4!} = \frac{13*12*11*10*9*8*7*6*5*4*3*2*1}{4*3*2*1}\\ \frac{13!}{4!} = 13*12*11*10*9*8*7*6*5 = 259459200 ways

Cathy and Iris have 259,459,200 ways to skip countries.
