After the lunch rush, ellen had used up all the small containers and half the large containers. which of these expressions can be used to find the number of plastic containers still on the counter? a 30 – 10 – 5 b 30x 1/2 -10 c 30- 10 - 1/2 d30 ÷ 3 – 5

Step-by-step explanation:

Let number of small containers

Let number of large containers

Total containers

Used Containers:

Small containers used

Larger containers used

Total containers used

Remaining containers=total containers-used containers

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
