A rappelling rope used for outdoor programs, rescue and industrial work, can safely support a weight "W" (in pounds) provided, where "d" is the rope's diameter (in inches). Determine the diameter of rope that would be needed to support a weight of at least 5,500 pounds.

D =  ( d * 5500 ) / W

Step-by-step explanation:

Diameter of rope " d "  supports "w" weight

i.e.  d = W

d ( inches ) = W ( pounds )

   ? ( inches ) = 5500 pounds

The Unknown diameter  D ( ? ) = d * 5500 / W

i need more info. are you looked to see there mph? how much they deliver? how far they go?

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
