Question 9

A full tank contains 8.90 ft.3 of helium, enough to fill 30 balloons.

To calculate the amount of helium needed to fill 50 balloons, first determine the unit rate, which can be calculated as 308.90. Next, create an equation to represent the relationship between h, the volume of helium, and b, the number of balloons: _[blank 1]_. Finally, plug in 50 for b and solve. The amount of helium needed is _[blank 2]_.

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

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
