In a lilac paint mixture, 40% of the mixture is white paint, 20% is blue, and the rest is red. There are 4 cups of blue paint used in a batch of lilac paint

a. white paint

If 20% of the mixture is blue paint and there are 4 cups of it, then there is twice the amount of white paint as 40% is twice as much as 20%

4 × 2 = 8 cups of white paint

b. red paint

same explanation as the white paint since the mixture is also 40% red.

8 cups of red paint

c. lilac paint

8 cups red + 8 cups white + 4 cups blue = 20 cups lilac

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
