A can holds 3 tennis balls. A box holds 4 cans. A case holds 6 boxes. How many tennis balls are in 10 cases?

720 balls

Step-by-step explanation:

Can = 3 balls

Box = 4 cans = 4*3balls = 12 balls

Case = 6 boxes = 6* 12balls = 72 balls

10 cases = 10 *72balls = 720 balls

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

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
