Is there a picture you can give us? I will try to answer it once you do! :)
...42, -193.. thats the 4th and 5th Hope this helps
What’s something goes up but never comes down?
100 cm = 1 meter
210 cm = 2.1 meters (multiply both sides by 2.1)
Mary uses 2.1 meters of thread so far, meaning she has 10-2.1 = 7.9 meters left
7.9 meters = (7.9 m)*(100 cm/1 m) = 790 cm
--------------------------------------
Alternate route:
10 meters = (10 m)*(100 cm/1 m) = 1000 cm
Mary uses 210 cm out of 1000 cm total, so she has 1000-210 = 790 cm left.

<h3>Answer: 790 cm</h3>
I don't see a drawing of the quadrilaterals, so I don't know what the perimeter of quadrilateral P is. But whatever the perimeter of P is, Q will be 1/3 of that. Perimeter is a length, so even though it may pertain to a 2-dimensional object, it is still a 1-dimensional, linear measure. When two objects are similar (same shape, but scaled up or down by a scale factor), all corresponding linear measures have the same scale factor.
If you were asked about area or volume, that would be a different matter. In the case of area, you would square the scale factor, and in the case of volume, you would cube the scale factor.
