In the cafeteria 100 were put out for breakfast. At the end of breakfast,27 remained. A. What is the ratio ofbthe number of milk cartons taken to the total number of milk cartons?

1. The ratio of milk cartons taken to total milk cartons,

100 - 27 = 73 were taken

73/100 is the ratio of milk cartons taken to total milk cartons

2. The ratio of milk cartons remaining to milk cartons taken

27 / 73 is the ratio of milk cartons remaining to milk cartons taken

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

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
