to get baby-blue paint, Farid needs to mix 5 parts blue paint with 2 parts white plant. Farid mixes 20 cups of blue with 8 cups of white

4 baby blue paints

Step-by-step explanation:

Given

Let b represents blue paint and w, white paints

---for 1 paint

Required

The number of paints in

To do this, we set the following equivalent ratios

Where n represents the number of paints

By comparison

Solve for n in both cases;

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
