Math is the study of abstractions. Math allows us to isolate one or a few features such as the number, shape or direction of some kind of object. Then we can study what can be learned about the behavior of those features while ignoring everything else about the object.
1 year = 365 days = 52 weeks 1 day.(1) If year 1 or year 2 of the 15 year period was a leap year then there would be 4 leap years in the period.(2) If year 3 or year 4 was a leap year then there would be only 3 leap years in the period.Each leap year gives 1 extra day.Condition (1) 15 years = 15 x...
Any one of them could be wrong. 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. For example, 2 is wrong. The rule for the sequence is: t(n) = (-23*n^6 + 636*n^5 - 7010*n^4 + 39330*n^3 -...
Your question is very unspecific. We would need to know the  vehicle's fuel efficiency (MPG) and how much local gas cost where  you're fueling. Terrain can also effect fuel efficiency.
15 divided by 5 is 3 and 15 divided by 3 is 5
7 US fluid ounces = 207.01 ml
To find 5 percent of a number, multiply the number by 0.05. In this  instance, 0.05 x 105 = 5.25. Therefore, 5 percent of 105 is equal  to 5.25.
The radius is tripled, too. Suppose: (1) C = 2πr (2) C' = 2πr' (3) C' = 3C Then C' = 3(2πr) = 2π(3r) But C' = 2πr', so 2πr' = 2π(3r) and finally r' = 3r.
8000 * 0.15 = 1200
Length is usually left to right, and the side that is not theheight or length is the width.
3.14159265358979323846264338327Note that although "DingoBot suspects that this answer includes Gibberish", that is the nature of PI!
The radius is directly related to the circumference of a circle by C=π 2R so it would get proportionately larger as the circumference grows. If you start with C=π 2R where 2R=C/π then change C to C2=3C then 2R2 becomes C2/π or 3(2R)/π
You need to know the density o f MgD = Mass/VolumeMass = Density * volumeDensity= 1.74 grams per cubic centimeterVolume = 2.5 * 3.5 * 1.5Mass = Density * volume
A straight edge is basically another name for a ruler, or it could  be anything that makes straight lines.
Because when there is a positive and a negative in the same problem, it gives you a negative. An easy way to solve problems like that is if there is an odd number of negative signs, then your answer is going to be negative. If there is an even number of negative signs, then your answer is going to...
5 fifths of a liter make one liter. One fifth of a gallon is 757 ml so you need 1 and a third of these to make a liter.1.32
0.8^100 = (8 × 10^-1)^100 = 8^100 × 10^-100 = 2.03703597633448608626844568840937816105146839366593625063614044935438 × 10^-10 ≈ 0.0000000002037035976334
36 square units.You can't express a perimeter in square units; a perimeter is a length expressed in ordinary units. If the perimeter of this square is 24 units then the answer above is correct.
7.5*1,000,000=7,500,000*1,000= 7,500,000,000. Ur welcome.
There are 100230 '3's in the first million digits of pi.
You'd really have to specify what kind of Pilot we're talking  about. Most pilots use basic mathematics to chart their flights,  including fuel usage, tonnage and PAX weight.
1 square inch = 645.16 square mm
Brackets (aka parentheses), eg 30 - 4 x 5 would normally be 30 - 20 ie 10, but (30 - 4) x 5 would be 26 x 5 ie 130 Not brackets....brackets has a completely different meaning in Access. The answer is parenthesis in this case.

one way is you could get rid of the fraction by the multiplying  everything denominator of the fraction and then just solving it  regularly.
Each has its own units of length. The metric system is more logical, because when you convert from one unit to another, you multiply or divide by powers of ten, which amounts to moving the decimal point. For example, 2.3 kilometers = 2300 meters; or .75 meter = 75 centimeter.On the other hand, a U....
If: n squared = 10n+56Then: n squared -10n -56 = 0When factored: (n-14)(n+4) = 0
Absolute value can be defined as the distance from the expression  to zero.   Therefore, the absolute value of 13 is 13.

There are 6 sides of a die, and rolling a 3 is one of the 6 sides.   Therefore, there are 5 sides on the die which is not a 3.    So, (outcomes wanted)/(total outcomes) = 5/6

If: 5x-3y = -34 then y = 5/3x+34/3 as a straight line equation whereas 5/3 is the slope and 34/3 is the y intercept
Well you have to set up a fraction ratio For example I want to convert 88 inches squared to mm not squared but just a length dimension88 inches x 1 mm/ 0.0393 inches = 2,239.185750636132 so inches ^2 divided by inches will leave you with inches and millimetres which is incorrect the correct way...
Digits that are powers of primes are 22 = 4, 23 = 8, and 32 = 9. So, the possible ages now are 44, 48, 49, 84, 88, 89, 94, 98, and 99. Twelve years ago you were a power of a prime, so subtract 12 from each of the numbers and look at them. Powers of primes include 22=4, 23=8, 24=16, 25=32, 26=64, 32...

 If the small triangles are worth 1, determine the value of the  other Tangram pieces.   Be sure to explain your reasoning.   More Challenging Version:   Find the fractional part each tangram piece is of the whole (all 7  pieces).   Now, suppose the large triangles are worth 1/2,...

You most likely typed the number in incorrectly, or the number you  are trying to type does not exist.
a = 4, g = 1,e = 9, l = 8, r = 7, o = 2, n = 6, b = 3, d = 5, t = 0
According to the CDC, Oral Contraceptives have a failure rate of  9%. Thus meaning their effectiveness is only 91%
When the recession supposedly officially ended in June, 2009,  the labor force participation rate was still 65.7%.  In the latest, much celebrated, unemployment report, the labor  force participation rate had plummeted to 63.7%, the most rapid  decline in U.S. history. That means that under...
In addition to Mr. Al Cohen's Expert answer I will add that  670,616,629 miles per hour equals about 11,176,943 miles per minute  or 186,282 miles per second.
It would be a discrete distribution, since the number of cups are countable.

If the two points are 'A' and 'B', you just told us that it's 170m . If 'A' and 'B' are not "the two points", then you've told us nothing about them. -------------------------- I trigonometry, we talk about "solving" a triangle. There are 6 pieces of information in triangle ABC: the 3 lengths AB,...
It depends on whether you are English or American. The traditionalEnglish billion is a million-million, while the traditionalAmerican billion is a thousand-million. Thus English Billion is 1,000,000,000,000 American Billion is 1,000,000,0009
You can't convert weight into distance. At a larger scale, this  would be like asking how many miles are in a pound.
One million, two hundred thirty-two thousand.
Entirely possible. Usually a working enviroment that pays commission will let you work any hours you want, but will require you to be there a minimum amount of hours.
In math, an interval is a set of real numbers with the property  that any number that lies between two numbers in the set is also  included in the set.
90/100 x 210 = 9 x 21   = 189

It is. Any number multiplied by 0 is 0.

Yes, a heptagon, also known as a septagon is a regular 7 sided  polygon.
The SI unit is the kilogram per meter (kg/m).
Pi is an irrational number that forms the ratio between a circle's  circumference and its diameter. To 30 places it is  3.141592653589793238462643383279.

I really don't think that is even possible. Sorry.
half of the radius. the radius is the distance across thecircle.
An intervening variable is a hypothetical internal state that is  used to explain relationships between observed variables
One kilogram is equal to 1000 grams. To convert grams into kilograms you need to divide by 1000. Therefore, 3500g = 3.5 kg
