if we mix the alcohol solution we have with pure water at the ratio 3: 2, we will obtain a solution of 18% alcohol. if we instead mix them at a ratio of 4: 1, what will be the alcohol percentage of the solution?

24%

Step-by-step explanation:

When the ratio is 3:2, that means 3/5 is the alcohol solution and 2/5 is pure water.

If x is the concentration of the alcohol solution, then:

3/5 x = 0.18

x = 0.3

So the alcohol solution is 30%.  If we mix it at a ratio of 4:1 (4/5 alcohol solution), the resulting concentration is:

4/5 (0.3) = 0.24

The alcohol percentage is 24%.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

3 is greater then both of those numbers
