The weight of a stack of standard 8.5x11 copier paper vs number of sheets of paper. is it proportional

The relationship between the weight of a stack of standard 8.5x11 copier paper vs number of sheets of paper is proportional.

Step-by-step explanation:

Let us assume here, in this situation that each page has the same weight so if i want to find the weight of the complete stack, I will multiply the number of sheets of paper by the weight of a single sheet of paper.

Yes it is proportional because w=kp k=paper weight which is constant.

Step-by-step explanation:

answer: what do you mean

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
