If you have a number such as 16584, which is sixteen thousand five hundred and eighty four, you can break it up into place value figures.
Meaning you would have:
16000
500
80
4
...which is the same number just in smaller denominations.
There are a many great ways in which you could add significant figures. You could simply add them with math.
At least 1 and at most 7. It could be 3,999,999.9 rounded to 7 significant figures; It could be 3,999,999 rounded to 6 significant figures; It could be 4,000,015 rounded to 5 significant figures; It could be 4,000,429 rounded to 4 significant figures; It could be 3,999,999 rounded to 3 significant figures; It could be 4,049,999 rounded to 2 significant figures; It could be 4,492,467 rounded to 1 significant figure.
Its area. The value will depend on the figure - regular figures will have relatively simple formulae. Figures that can be decomposed into regular figures will also be relatively straightforward. But you could have a wiggly loop and finding the area inside that would be more difficult.
A two-dimensional (2D) figure is a plane figure which is flat and shows one face (could have several sides) and no depth.
A 2-dimensional (plane) projection of a 3-dimensional (solid) figure. Or, for polyhedra it could be a net but that answer would not be applicable to many 3-d figures.
draw 3 line segments connect the endpoint what figure is formed
Some synonyms for star-shaped figures include asteroform, stellate, stelliform, astromorphic and multi-pointed. Star-shaped figures could also be described as polygons.
Congruent figures have exactly the same shape; you could superimpose one on the other and see only one figure. Similar figures have some points of similarity but do not have to be exactly the same.
i have no clue i am trying to find it in the book but thats not working......
Yes. A quadrilateral is any four sided figure, so you could draw any number of these figures that have no right angles...a parallelogram for instance.
If the zeros are significant figures then 900 is correct to 3 significant figures. If rounding off has occurred then the answer could be 1 sf or 2sf. For example : If the original number was 903 and rounding off to the nearest ten was required then 900 is correct to 2 significant figures. If the number was 927 and rounding off to the nearest hundred was required then 900 is correct to 1 significant figure.
The remaining shape could be a [concave] hexagon although in some circumstances it could be a smaller parallelogram.
