Answer:

52.8%

Step-by-step explanation:

The amount of alcohol is:

0.28 (6 pints) + 0.90 (4 pints) = 5.28 pints

So the concentration is:

5.28 pints / 10 pints × 100% = 52.8%.

Graph this line using the slope and y-intercept:
earnstyle [38]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y=2x+5

This is the equation of the line in slope intercept form

y=mx+b

where

the slope m is equal to

m=2=\frac{2}{1}

That means ----> The slope of line rises 2 up and run 1 to the right

b=5 ---> the y-intercept is the point (0,5)

To graph the line i need minimum two points

I have the y-intercept (0,5)

From the y-intercept (0,5) use the slope to find your next point

The slope is 2, so you will rise 2 (up) and run 1 (to the right).

The next point is (0+1,5+2) -----> (1,7)

Plot the points (0,5) and (1,7)

To graph the line joint the points

see the attached figure

The third angle of a triangle is the same size as the first. The second angle is 4 times the third. Find the measure of angles.
Marta_Voda [28]

Answer:

1st angle 30°

2nd angle 120°

3rd angle 30°

Step-by-step explanation:

Let's call

A = 1st angle

B = 2nd angle

C = 3rd angle

In every triangle it holds

A + B + C = 180°

Now, if the third angle of the triangle is the same size as the first

A = C

If the second angle is 4 times the third

B = 4C

we have then

C + 4C + C = 180° ===> 6C = 180° ===> C = 30°

If C = 30° then A = 30° and B = 120°
