How much is 2000 times 7 billion?
We can solve this by putting the numbers in scientific notation.2 x 103 x 7 x 1092 x 103 x 7000000 x 10314000000 x 1031.4 x 1010
What numbers are equal to their reciprocals?
These are numbers x such that x = 1/x. But this means that x2 = 1. Try solving this last equation for x. (i.e. the only numbers are +1 and -1)
What are four consecutive numbers that add up to 162?
Consecutive numbers: x is the first number (x)+(x+1)+(x+2)+(x+3) 4x+6=162 Therefore x=39 Numbers are 39, 40, 41 and 42
What is the minimum product of two numbers whose difference is 22 what are the numbers?
Suppose the smaller of the two numbers is x. Then the other number is x+22. Their product is x*(x+22) = x2 + 22x This has a minimum when 2x = -22 or x = -11. When x = 11, the two numbers are -11 and 11 with a product of -121.
If there are three consecutive numbers and the sum is 81 what are the three consecutive numbers?
Let the second number be x, then the three consecutive numbers are x-1, x, x+1, and their sum is: (x-1) + x + (x+1) = 81 3x = 81 x = 27 So the three numbers are 27-1, 27, 27+1 = 26, 27, 28
Describe two methods of comparing numbers?
If you have two numbers X and Y then One method of comparison is to calculate X - Y. If the answer is positive then it tells you how much more X is compared to Y. If the answer is negative then it is how much more Y is compared to X. If Y is not 0, then X/Y tells you how many times X is compared to Y.

What is the sum of the first x odd numbers?
This depends on what "x" is. The sum of the first x odd numbers is equal to x^2 or x*x.
The sum of 3 consecutive page numbers is 207 how do you find the numbers?
Call the numbers: x, (x+1), and (x+2)The sum is: x + (x+1) + (x+2) = 3x + 3 = 2073x = 204x = 68The numbers are 68, 69, and 70.
Is there any number x such that x² is an irrational number and x's is a rational number?
no x² is the product of 2 rational numbers in this case the same 2 numbers x and x The product of two rational numbers is always rational.
What numbers are equal to their reciprocals?
These are numbers x such that x = 1/x. But this means that x2 = 1. Try solving this last equation for x. (i.e. the only numbers are +1 and -1)
What numbers multipleyed equals 728?
There are an infinite number of ways to multiply numbers and get a result of 728.If you look at products of only two numbers, and only positive numbers, and only whole numbers,then here are a few examples:1 x 7282 x 3644 x 1827 x 1048 x 9113 x 5614 x 5226 x 28And there are millions and billions more.
How many variations can you get in 45 numbers?
If you have a set of 45 numbers, then there is one combination that includes all 45 numbers and 45! = 45 x 44 x 43 x ... x 2 x 1 ≈ 1.19622 x 1056 permutations (ways of ordering) all 45 numbers.
How do multiply 3 numbers by 3 numbers 3 times?
[(aXbXc)X(dXeXf)]X[(aXbXc)X(dXeXf)]X[(aXbXc)X(dXeXf)]
What numbers multiply to get 168 using prime numbers?
168 = 2 x 2 x 2 x 3 x 7.
How many combinations of 4 numbers can be made of 36 numbers if you can not repeat the numbers?
( 36! )/( 32! ) ( 4! ) = (36 x 35 x 34 x 33)/(4 x 3 x 2) = 58,905
