Sin= p/h , cos= b/h , tan= p/b
4 / 0.80 = 12 / x...cross multiply
4x = 0.80 * 12
4x = 9.6
x = 9.6 / 4
x = 2.4.....12 apples cost $ 2.40
Well I only know the first one
Air? Unless you mean like a toy boat? IDK, I do know that huge ships like the Titanic are able to float because they have trapped oxygen. Think about if you're swimming; often when you hold your breath you float a bit better than if you were heavily breathing. Sorry i know its not alot to go off of, did i help you a little?
See in the explanation

Explanation:</h2>
We can write the Slope-Intercept form of the equation of a line as:

The slope is a measure of the steepness of a line It is a ratio between vertical change (run) and horizontal change (rise), so we can also write the slope (m) as:

We have the following facts:
- If we increase the rise, the slope also increases and if we decrease the rise the slope also decreases.
- If we increase the run, the slope decreases and if we decrease the rise the slope increases.
