How many ounces of 10% alcohol would need to be mixed with pure rubbing alcohol to get 16

givi [52]

Suppose you add x oz of 10% alcohol to y oz of pure alcohol. Then the mixture has a total volume of x + y oz, and we want to end up with 16 oz so that

x + y = 16

For each oz of the solution 10% used, 0.1 oz of alcohol is contributed, and each oz of pure alcohol contributes 1 oz of alcohol. The mixture is supposed to have a concentration of 14%, which comes out to 0.14*16 = 2.24 oz of alcohol. Then

0.1 x + 1 y = 2.24

Solve for y in both equations:

y = 16 - x

y = 2.24 - 0.1 x

Set them equal to one another and solve for x, then for y.

16 - x = 2.24 - 0.1 x

13.76 = 0.9 x

x = 13.76/0.9 ≈ 15.29

y = 16 - 15.29 ≈ 0.71

So you need about 15.29 oz of 10% alcohol and 0.71 oz of pure alcohol to get the desired mixture.

PLEASE ANSWER ASAP

ivolga24 [154]

The rate of change, or slope, is the change in y over change in x. To find the slope, pick two points. The slope will be the change in y-coordinates over the change in x-coordinates.
As an equation, this is
$slope = \frac{(y2-y1)}{(x2-x1)}$

To find the slope for function 1, pick any two points (x,y) in the table.
Let's choose (-1, 3) and (-2, 5).
The slope is
$\frac{5-3}{-2+1} = \frac{2}{-1} = -2$ .

Let's choose (-1, 0) and (0, 4) for the two points for function 2.
The slope is
$\frac{4-0}{0+1} = \frac{4}{1} = 4$ .

You want to compare the magnitude (without negatives) of the slope when comparing the greater rate of change/slope. In other words, you take the absolute value of each slope.
The magnitude of function 1's slope is 2.
The magnitude of function 2's slope is 4.
