It depends on how you define natural numbers. There are two possible definitions.
1. All non-negative integers.
one-digit natural numbers: 0 - 9 for a total of 10
first 20 natural numbers: 0 - 19 for a total of 20
10/20 = 50%
2. All positive integers.
one-digit natural numbers: 1 - 9 for a total of 9
first 20 natural numbers: 1 - 20 for a total of 20
9/20 = 45%
Answer:
-1500 hairs
Step-by-step explanation:
You lose 150 hairs for 10 days

You first have to distribute correctly so it simplifies is 15+3n
Answer: y = 48/x
Step-by-step explanation:
y ∝ 1/x
Introducing the proportionality constant, we have
y = k/x
substituting the value of x and y , we have
6 = k/8
k = 48
Therefore the equation becomes
y = 48/x
