Math History
Far more interesting than one might first expect, the history of mathematics is filled with bitter rivalries, political machinations, and incredible innovations by some of the most amazing minds in history. Post all questions concerning individual mathematicians, the development of mathematical theories, and the sociological impact that resulted into this category.

How do you find surface area of a four sided thing which is not square or rectangle?
FIRST, measure the bottom half. (Measure A)
SECOND, measure a STRAIGHT verticle line from top to bottom. (Measure B)
Multiply A by B.
This works because it can be turned into a rectangle or square. First, make a sraight verticle line starting from the left hand bottom corner. Go up until you meet the upper line. The triangle you have just created should fit into the space that is unoccupied to make a square/rectangle.
Hope this helped!
. okay, that didnt help. because the poor person up there, probably my reincarnation, SAID ITS NOT A SQUARE OR A RECTANGLE. like all sides uneven, pretty retarded looking excuse for a shape. your wrongggggggggggggg and i need help. rawr.
Zero is needed in numbers for positional place value purposes because it tells us that there is a difference between for example 27 and 207
Congruent angles exactly the same size and shape. They have the same measurements. For example, two angles are congruent if they both measure 85 degrees, or if they both measure 621 degrees. As long as they have the exact same measurement, angles are congruent. But they do not have to be the same length and width.
The definition of congruent is:
con·gru·ent /kənˈgro͞oənt/Adjective:
- In agreement or harmony.
- (of figures) Identical in form; coinciding exactly when superimposed.
As noted with the mathematical example above, they are identical angles. If you put two congruent triangles over one another, they will look the same.
In a cube, all sides if sliced off from each other until they are each 2D squares, will all be congruent.
What is the relationship between scale factor and perimeter?
It is a strict linear relationship. Double the size, double the perimeter. The area, however, increases by the square of the scale factor.
What is the name of a 16 sided polygon?
A 16-sided figure is known as a hexakaidecagon, 16(sixteen)-gon, or hexadecagon.
we use them in situations that involves going in between numbers!
When you're out buying food for a group of people, or sharing something, you'll want to share it equally... So, say you were buying a large pizza for 4, and it cost $10, you'd have to do 10/4 to know the exact amount that each of you is to pay to make it fair...
How do you figure out distance?
A 1/2 diameter piston moves 10 inches with 30 lbs force how far will it move with 6 inch diameter piston and how much weight will it lift
How old would you be if you were born in 1975?
Take the current year and subtract the birth year to get their age. Then, you will get a number which is their current age, or the age that they will turn this year. * 2009 - 1975= 0034 With this information, you could even do this: * 2009 - 33= 1975 But, you already knew the year that the person was born in.
2011-1975 = 36
What are three consecutive odd numbers that equal -99?
Lets substitute the first number by -x(so x has a positive value), so the next two consecutive odd numbers would be (-x-2) and (-x-4). Then, put it all into an equation: -x+(-x-2)+(-x-4)=-99 -3x-6=-99 -3x=-99+6 x=-93/-3 x=31 so the next two numbers would be (-x-2) which equals (-31-2)=-33 then (-x-4)= (-31-4)=-35 So at last the three conecutive odd numbers are: -31, -33, -35 and to check your work you can add them up (-31)+(-33)+(-35)=-99
