A paint mixer calls for 3 parts of white paint to 8 parts of red paint to make pink. How many parts of red paint would you mix with 12 parts of white paint to get the same shade of pink?

32 parts red

Step-by-step explanation:

3 parts white : 8 parts red

12 parts white : ?

12/3 x 8 = 32 parts red

32 parts

Step-by-step explanation:

We can use ratios to solve

3 white           12 white

=

8 red              x red

Using cross products

3x = 8*12

3x = 96

Divide each side by 3

3x/3 =96/3

x= 32

Answer with explanation:

Equation of Parabola that opens Downward having vertex at (0,4) is given by:

It is also given that,  vertex of a second parabola is at (0, –4).

Also, it is given that Parabola Intersect at two points.

 So, the parabola must open upward to intersect at two points.

Equation of Parabola having vertex (0,-4) ,is given by:

It is not necessary that , point of intersection is on the x axis, the two parabolas can intersect anywhere.

Option B: The second parabola opens upward
