How do you divide $306 into the ratio of 9: 5: 3? can someone give me some advice on how to solve this problem?
and does anyone know anything about pre-tax prices?

In order to divide $306 into the ratio of 9 to 5 to 3, first you have to make each section of the ratio represented by a variable, and put it into an equation.

9x + 5x + 3x = 306

Our next step is to simplify the left side of the equation by combining all of the like terms, the ones that contain variables.

17x = 306

Finally, to solve this equation, you have to divide both sides by 17 to isolate the variable x on the left side of the equation.

x = 18

However, this is not our answer as it isn't in a ratio format and doesn't really make sense. To find our ratio, we have to multiply each of our initial numbers (9, 5, and 3) by our variable, x.

9 * 18 = 162
5 * 18 = 90
3 * 18 = 54

You can verify that these numbers are correct because if you add them together you get 306.

Your final ratio is 162:90:54.

Hope this helps! :)

If you have a separate specific question about pre-tax prices and PMed me the link, I'd be happy to help you.

Step-by-step explanation:

We have the motion equation as follows

When the projectile touches the ground we have the height equal to 0

-16t^{2}+ 48t +190=0

we need to to solve this quadratic equation with:

In this case A=-16, B=48, C=190

The results are -2.25 s and 5.3 s, since time is a positive variable the final answer is 5.3 seconds
