There are 35 children for every 6 teachers. Using the same child to teacher ratio, how many teachers needed for 140 children?

24 teachers

Step-by-step explanation:

The ratio of children to teacher is 35 : 6 or . To find how many teachers is needed for 140 children, you would need to use the following equation:

.

To solve this, you would need to cross multiply.

35 * x = (140) * (6)

35x = 840

           Divide both sides by 35

x = 24

Another way to do it:

          Multiply x to both sides

x = 24                Divide both sides by 35

answer: the first graph

step-by-step explanation:

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
