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.
The remaining shape could be a [concave] hexagon although in some circumstances it could be a smaller parallelogram.
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.
