The team has fifteen members and each member sells an unknown amount of coupon books.
We need to know the bases first.
Plus, if you are finding the area
the equation would be like this
A: 1/2 (b1+b2) x 12h
Answer:
the answer 2
Step-by-step explanation:
i done this before
I believe it is a Polaris Slingshot. It is a street-legal motorcycle. And yes, it is classified as a motorcycle. I really want one!! They typically start at around $30,000!
I found this on Yahoo answers 18 different sets.
There are 6 faces, so that's 6 sets.
If we draw two parallel diagonals on two opposite faces, their endpoints are another set of four coplanar points. There are 3 pairs of opposite faces, and each has two such sets of diagonals, giving us another 6 sets.
Now consider the four diagonals of the cube. They all meet at a single point in the center of the cube. Therefore, any pair of them represent a pair of intersecting lines and so define a plane. So any pair of these diagonals produces yet another set of four coplanar vertices.
There are four such diagonals, and there are
4C2 = 4! / (2! 2!) = 4 * 3 / 2 = 6 different combinations comprised of two of them, so that's another 6.
That gives us a total of 18 different such sets of four coplanar vertices of the cube. No other combinations of four vertices are coplanar.
