How many edges on a 3d triangular prism?
A triangular prism has nine edges, three edges that are parallel to each other on the top and bottom of the prism, and three surrounding edges. It also has five faces and six vertices.
What is the difference between a polyhedron and a regular polyhedron?
A Polyhedron is a closed plane figure whose faces are portions of planes. Prisms and pyramids are examples of Polyhedron's. While a Regular Polyhedron is a Polyhedron whose facces are all regular Polygons and whose Vertices are all alike. There are only five Regular Polyhedron's: Tetahedron , Octahedron , Icosahedron , Hexahedron , and Dodecahedron .To clarify, there are five known Platonic Solids: regular polyhedrons which are convex on all their vertices.The tetrahedron is also known as the triangular pyramid: a regular one has an identical equilateral triangle for each of its four faces. This is the one Platonic solid which is self-dual, as each face has three sides and each vertex joins three edges.The regular hexahedron is better known as the cube: each of its six faces is a square, and each vertex joins three edges. Its dual counterpart is the regular octahedron. In this case, each of its eight faces is three-sides (an equilateral triangle) and each vertex joins four edges. To picture the octahedron, think two square pyramids mated on their square faces, leaving only the triangular faces.Finally, there is the regular dodecahedron (12 faces), which is composed of regular pentagons (five sides). Each vertex again joins three edges. Its dual counterpart is the regular icosahedron. It has 20 triangular faces, and each vertex joins five edges.
Euclidean and Non-Euclidean geometry strictly adhere to all five postulates from Euclid's Elements?
False
What shape has five vertices and five faces?
A pyramid is a three-dimensional figure with five verticies and five sides (four of which are triangles and one of which is a square). A pentagon is a two-dimensional figure with five angles and five edges.
How many sides do five pentagons and three quadrilaterals have altogether?
A pentagon has five sides, and a quadrilateral has four sides. So five pentagons and three quadrilaterals have 5*5 + 3*4 sides = 25 + 12 sides = 37 sides.
The number of subsets in a set with five elements?
32.
How many subsets are in this set a b c d e f?
64. You can use Pascal's triangle to figure out how many subsets have no elements, one element, two elements and so on. For this particular one, you will have 6 subsets with one element, 15 with two, 20 with three, 15 with four, 6 with five and only one each of all six and none at all.
What represents the number of subsets of five elements can be formed from a set of six elements?
c(6,5)
How many subsets can be made from a set with 6 elements?
If a set has six elements, for example {A, B, C, D, E, F}, then it may have the following subsets: - the set itself - 6 sets of five elements - 15 sets of four elements - 20 sets of three elements - 15 sets of two elements - 6 sets of one element - 1 set with no elements (the null set), for a total of 64 sets, which is 2^6, or 2 to the 6th power.
How many subsets are in the set 12345?
Number of subsets with no members = 1Number of subsets with one member = 5.Number of subsets with 2 members = (5 x 4)/2 = 10.Number of subsets with 3 members = (5 x 4 x 3 /(3 x 2) = 10.Number of subsets with 4 members = (5 x 4 x 3 x 2)/(4 x 3 x 2) = 5.Number of subsets with 5 members = 1Total subsets = 1 + 5 + 10 + 10 + 5 + 1= 32.A set with n elements has 2n subsets. In this case n = 5 and 25 = 32.The proof in the case that n = 5 uses a basic counting technique which say that if you have five things to do, multiply together the number of ways to do each step to get the total number of ways all 5 steps can be completed.In this case you want to make a subset of {1,2,3,4,5} and the five steps consist of deciding for each of the 5 numbers whether or not to put it in the subset. At each step you have two choices: put it in or leave it out.

When elements gain three electrons to fill its valence energy level?
When these elements have five electrons on the outermost shell of electrons.

How many fingers are on three feet?
None. Most people have five fingers on each hand and five toes on each foot.
How many elements in?
The letters represent elements, the numbers represent the quantity of each element within the compound. I believe it should read 5H2SO4 meaning there are five molecules of the compound H2SO4 (which happens to be sulfuric acid). In this solution there are three different elements: Hydrogen (H) Sulfur (S) Oxygen (O) In each molecule of H2SO4 there are two Hydrogen atoms, one Sulfur atom, and four Oxygen atoms. In the complete sample, five molecules of H2SO4, there are ten Hydrogen atoms, five Sulfur atoms, and twenty Oxygen atoms.
What are some practical uses for elements in the halogens?
There are 5 practicals that use elements in the halogens. The five practicals are fluorine, chlorine, bromine, iodine, and astatine.
