Often, to completely understand the importance of a mathematical theory, it's essential to know about the person who developed it. This category is where all questions about historically significant mathematicians should be asked.

What is th mean for 6281454562?
The mean for a single number, such as 6281454562, is the number itself.
Is 2750 a reasonable answer for 917 times 33?
No.900 * 3 = 2700 so 900 * 30 = 27000 and then 917*33 will be larger still. So it is an extremely poor answer.
Which has a higher population desnity a city or an area in the countryside?
A city has a higher population density.
Is associative properties and associative properties of addition the same?
No because the associative property can be found in other operations as well.
Pi is a number, a mathematical concept. It doesn't "exist" in a physical sense in the first place (yes, it's the ratio of the circumference of a circle to its diameter, but it also shows up in many surprising equations that are purely numeric and not obviously connected to circles), so it's nonsensical to ask what would happen if it "didn't exist".
If we didn't know about it (which is a very different thing) then ... nothing would happen, other than that we'd have to actually measure the circumference of circles if we wanted to know how big around they were, rather than calculating it from the diameter (which is usually significantly easier to measure).
How do you do -5 8ths divided by 5 equals?
you can divide -5/8 by 5 by multiplying -5/8 x 1/5. The 5's cancel and you are left with -1/8.
How do you round by the nearest half?
If a number is 1.2, it would be rounded to 1 because a half is 0.5. If the number is 1.25 it would be rounded to 1.5. If the number is 1.24 it would be rounded to 1.
What is the 8th term for 12 59 294 1469 7344?
Any number that you choose can be the eighth term. It is easy to find a rule based on a polynomial of order 5 such that the first five numbers are as listed in the question followed by the chosen number in eighth position. There are also non-polynomial solutions. Short of reading the mind of the person who posed the question, there is no way of determining which of the infinitely many solutions is the "correct" one.
The simplest answer, based on the following polynomial of order 4 U(n) = (376*n^4 - 3384*n^3 + 11186*n^2 - 15369*n + 7227)/3 for n = 1, 2, 3, ...gives U(8) = 135889.
How many 1 foot rulers laid end to end would it take to equal 5 yards?
15 of them because 15 feet = 5 yards
