Lee washes the outsides of houses. it takes him 40 minutes to power wash a one-story home, and he uses 180 gallons of water. power washing a two-story home takes less than 90 minutes, and he uses a maximum of 5,000 gallons of water per week. lee works no more than 40 hours each week, and his truck holds 500 gallons of water. he charges $90 to wash a one-story home and $150 to wash a two-story home. lee wants to maximize his weekly washing income washing houses. let x represent the number of one-story houses and y represent the number of two-story houses.
what are the constraints for the problem?

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
