## Math and Arithmetic

Parent Category: Science
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.

It's easy to convert from Celsius to Fahrenheit by yourself. Tf = (9/5)*Tc+32, where Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit.103 C is 217.4 F.
x= -6 + square root of 7, -6 - square root of 7
A tricky question: Mass is a measure of the amount of matter in an object (such as 100g); weight, however, is the measure of the force of gravity on an object. So, weight depends on where you are. If you are here on earth, a 100g mass would weigh 100g. On the moon (with 1/6th the gravity of the...

Well if you're talking about one lap being 'swimming to the other  end of the pool and back again' , then it would be 85% of a mile or  0.85 of a mile, whichever one you prefer to call it :)
2,992,126 = 2992126/1
A nonagon is a 9 sided polygon and its 9 interior angles add up to  1260 degrees
A regular pentagon has five congruent interior angles so yes :)
If you do it too many times, yes. One or two, no problem.
You can fit nine 4x4 tiles in one squre foot (3 tiles wide by 3 tiles long). 56 square feet times 9 = 504. Add about 10% for cutting a/o waste (50 tiles) and you should buy around 550 tiles to complete the job. Good luck.
Try to bring in shapes that are 3D, pyramid, cube, sphere, etc. Explain why the object you are holding is 3 Demensional. Try also asking them why a certain shape is 3 Dimensional, for instance, "What does a 3 Dimensional Square look like?" Let them get interactive and explain to them that a 3...
A Diophantine Equation. In order to solve it, you should use  Euclide's algorithm.

Write an essay on the impact of policy dynamics on policy changes  within the policy making process in the public sector
most common answer; 0. . +++ . The '0' value is correct - a constant speed or velocity (notsynonyms) is one of no acceleration or deceleration - but it's notthe "most common" answer, it is THE answer! :-)
normally when people say "which of the following" there are actually choices following it below...

7.36649737 × 109 square feet.
They are: 1, 2, 4, 8, 16, 32, 64, 128, 256.
You should absolutely learn binary. First, because it's really  really easy. It's like the math you already know, but with fewer  digits. Second, because binary and hexadecimal are an easy way to  understand the native "size and shape" of numbers inside computers  -- and *that* is important.
Yes, it is true that any number multiplied by 0 is 0. But zero is  not considered a "multiple" (integral product) of any number.
% rate = 26.67%= 4/15 * 100%= 0.2667 * 100%= 26.67%
It should be 850%
27, 26, 676, 678, 677, 458329, ect... The pattern is multiply by  itself, add two, subtract one (repeat)
Forty-seven hundreds is the same as 4,700, so expressed as a fraction it is technically 4700/1. If, however, you meant forty-seven hundredths, it is written 47/100.
A discrete number is a full, whole number while a continuous number  may be any value in a range. Since a committee consists of people,  and people aren't divisible, a committee consists of a whole number  (discrete) of people.
Since it doesn't have any common factor, therefore the LCM will be the multiplication of the three numbers, i.e. 2x3x13 = 78
Lead density = 11.34 gram/cubic cmFor 10 cubic cm, mass is 113.4  grams
The progression from Shockley diode to SCR is achieved with one  small addition, actually nothing more than a third wire connection  to the existing PNPN structure. If an SCR's gate is left  floating (disconnected), it behaves exactly as a Shockley  diode. It may be latched by breakover voltage...
Converting a number to a percent is easy; just multiply by 100: 0.0051 x 100 = 51%
 One of the most confusing and misleading metrics in the home  building and home selling business is area - the "size" of a  house.   The problem is that there's no adopted standard; everyone measures  it differently. There has been a move in the past few years to  create a universal...
An even function is symmetric about the y-axis. If a function is  symmetric about the origin, it is odd.
Hermite proved that "e" is transcendental, but it was Ferdinand Lindemann who proved that "pi" is transcendental.

there are 29 zeros in the first 200 digits of pi.
Yes, the result is 5,030.
yes, but not necessarily a square
Suppose the purchase price of a dining room set is \$650.If the sales tax is \$58.50, what is the sales tax rate?
Answer: 88 km = 54.6806 mi.
A fifth of a pound is twenty pennies. So three points, divided by  five, is sixty pennies.   Twenty pennies divided by five equals four pennies.   So the total is 64 pennies or 0.64 pounds.
They are the numerals or numbers which we use today in the form of  0 1 2 3 4 5 6 7 8 and 9
No. Standard deviation is not an absolute value. The standard deviation is often written as a single positive value (magnitude), but it is really a binomial, and it equals both the positive and negative of the given magnitude. For example, if you are told that for a population the SD is 5.0, it...
Rounded to 3 places it would be 67.612 and 0.388
7000 is a number with ambiguous zeroes. Written this way, we can't be sure whether or not the zeroes are significant. You have specified 2 sig figs, so we must use scientific notation. Scientific notation specifies: A nonzero digit (1-9) in the 'ones' place A decimal for two or more sig figs ...
The point that moves (if none a new point is made) goes up or down  the graph.   Up is a positive number.   Down is a negative number.
576 feet x 12 inches in a foot = 6912 inches 6912 inches/18 inches per tile = 384 tiles
Evariste Galois worked on quadratics when he was a teenager. He was  able to establish the means to solve quadratics using radicals and  laid the ground work for what became Galois theory. Unfortunately,  he died when he was only 20 years old during a duel.

Yes and no.Only in maths does this exsist.Yeah but........ Time itself doesn't exsist.So if there is no time.There's not really a 4th dimension. I.E in maths time is not the 4th dimension yes it does exist in maths, there have even been drawings of 4d cubes. A possible reason they call time 4th...
x-y=0   x=y   so you will use that in the other equation by substituting every y  with x   2x+y=0   2x+x=0   3x=0   x=0/3   x=0   then use that in the previous equation by substituting every x with  0   x=y   0=y; y=0   finally x=0 and y=0
It depends upon the year of your birth.    The age on your birthday in any year is given by:    age = year - year_of_birth    If the date in a year is before your birthday, then your current  age is 1 less than this.    So, if you were born on 12 June 2002, your age on your...

1 litre is a cube with sides 100mm, so 100 x 100 x 100 = 1,000,000.1 litre = 1million mm3
Generally you spell out numbers that are ten or below, between  eleven and twenty you can probably do as you like. The larger a  number, the less likely you are to spell it out. To be safe, you  can always spell out a number and add the numeral in parentheses  behind.   There is no particular...
The median lethal dose is the average dose of a toxin that could cause death for specific individuals, taking into account age, height, weight, and general health. The median toxicity dose under the same conditions is the amount of a toxin needed to make one ill.

Just divide the number by four.
When you multiply a one- digit number by nine, then add up the digits, it does equal nine. 9x1= 9 9x2= 18 1+8=9 9x3= 27 2+7= 9 9x4= 36 3+6= 9 9x5= 45 4+5=9 ETC. also, for the number you are multiplying by, the product's first digit will be one less than the number
