Anna-Maria has added 4 quarts of an alcohol in water solution to 1 quart of water and her ending product is a 36% alcohol in water solution. What was the concentration of the 4 quarts of alcohol solution that was added?

Answers

Answer 1

Answer: The concentration of solution would be the amount of the molecule divided by the volume. In this case, the solution concentration is 36% and the volume is 4 quarts + 1 quarts= 5 quarts. You are asked the concentration before 1 quarts added. The alcohol content should be same for both solutions. The answer should be:

concentration = alcohol content/ volume
alcohol content =concentration * volume
alcohol content1 =alcohol content2
36% * 5 quarts = concentration2 * 4quarts
concentration2= 36% * 5 quarts / 4 quarts= 45%

Answers

Answer:

m = 0.421

Step-by-step explanation:

5.4(m-2)= -2(3m+3) (expand parentheses by distributive property)

m(5.4) -2(5.4) = 3m(-2) + 3(-2)

5.4m - 10.8 = -6m - 6 (add 6m to both sides)

5.4m - 10.8 + 6m = - 6

11.4m - 10.8 = - 6 (add 10.8 to both sides)

11.4m = -6 + 10.8

11.4m = 4.8 (divide both sides by 11.4)

m = 4.8 / 11.4

m = 0.421

Answer:

m = 8/19

Step-by-step explanation :

5.4 (m-2) = -2 (3m +3)

54/10 (m-2) = (3m +3) as n = 1

2.3^3 / 2.5 (m-2) = (3m + 3)

4.868 (m-2) = (3m +3)

4.868 + 3 = (3m^2 * m-2)

8 / 9.5 * 2

m = 8 / 19

What type of polynomial is 3x+x to the second power +4quartic

cubic

linear

quadratic

Answers

The answer is quadratic.

A quadratic equation takes this form:

ax^2+ bx + c

The "a,""b,"and "c" represent numerical coefficients.

This is how your equation looks:

3x + x^2 + 4

Now it is standard that we organize the polynomial in descending order so it will look like this:

x^ 2 + 3x + 4

(commutative property of addition says that the arrangement will not affect the result)

It matches the quadratic polynomial form.

* You might be thinking, x to the second power has no number next to it though, well actually it does. The numerical coefficient of x to the power of two in this case is actually 1. It's just that in math, it is not necessary to put the one anymore. It is already assumed.
