Answer: 32760 ways.
Step-by-step explanation:
To solve this, we first determine the number of ways to select 4 countries from 15, we calculate number of ways to visit these 4 places then we multiply.
Selecting number of ways to choose 4 cities from 15 is by using the combination formula, which becomes 15C4
Number of ways to visit these 4 cities = 4!
Hence,total number of ways of visiting these 4 cities = 15C4 * 4! = 32760ways
Answer:

He makes $52436.80 a year.
Answer:
x = 14
Step-by-step explanation:
The 2 given angles are vertical angles abd are congruent, so
4x - 22 = x + 20 ( subtract x from both sides )
3x - 22 = 20 ( add 22 to both sides )
3x = 42 ( divide both sides by 3 )
x = 14
Then
x + 20 = 14 + 20 = 34°
4x - 22 = 4(14) - 22 = 56 - 22 = 34°
