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: You have 34 left.
Step-by-step explanation:
69 - 15 = 54
54 - 20 = 34
answer 13/30
or 0.43 repeating
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Given
V = πr²h
Isolate h by dividing both sides by πr²
= h → C
So the equation would be 4x+x=30. So since they have the same variable, x and 4x, you add them together to get 5x=30. Then you divide by both sides and get x=6. So there are 6 spaniels.
