Human body has 209 bones, 2.9% are in the inner ear hw many bones are in the ear?

lubasha [3.4K]

First, we should change this question into an expression.
- we convert the percent into decimal
209 × 0.029 = 6.061 (I used a calculator for this)

So there are approximately 6 bones in the inner ears, which is approximately 3 bones in each ear.

hope this helps

The inequality 5m − 7 > 16 holds true for all numbers than in the set {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.

mash [69]

Answer:

{5, 6, 7, 8, 9, 10}

Step-by-step explanation:

Given the inequality

5m - 7 > 16

Add 7 to both sides

5m-7+7>16+7

5m>23

Divide both sides by 5

5m/5>23/5

m>4.6

Hence the value of m are the values in the set greater than 4.6 and they are {5, 6, 7, 8, 9, 10}
