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.
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
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.
  5 foot 7 inches=170.18 centimeters
By graphing the lines on the coordinated plane they will intersect  at (2, -4) which is the solution of the equations
Maria Agnesi died in January 9.1799 by a heart attack at a zoo
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...

Aristotle had two wives his first was Pythias, who died. Then he married Herpyllis who together they had a child named Nichomachus.
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 Hindu-Arabic positional system, as in every other country for at least 1500 years!
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
x*6=68  x=68/6=> x=34/3
They face the direction in which the cold air is advancing.
Multiply 9*16 to see how much it would measure in square meters.  Then, multiply it by 1.25 which is the cost of each square meter.
The SI unit of mass is the kilogram, kg.
just as a 1 cm long train takes 2 minutes for the front and the back to completely traverse the tunnel
43,560 square feet=1 acre    A square that measures 50 feet on every side has an area of (50 x  50)=2,500 square ft.    2,500 square feet=(2,500 / 43,560)= 0.0574 of an acre (rounded)
None. Centimeters are a measure of length while tablespoons are a  measure of volume.
Scientific method is described as a scientific approach to a problem. To solve a problem you must first find the problem, access it, hypothesize a solution, illustrate your solution, try the solution, and then finally try it. If this does not work start over.
Depends on how fast your going. If you drive 60 miles per hour it will take you and hour and a half to drive 100 miles. If you drive at 50, it will take 2 hours. MPH is how many miles you'll achieve in one hour, so do the math and you'll find out.
First, you must make sure that the denominators are the same, so if  you are adding 3/6 + 4/8, you have to make the denominators the  same, but how?   to make the denominators the same, you have to find the LCM, which  is the least common multiple, and in this case, 24 is the LCM, and  so...
If you are trying to find the volume of something, remember there  is a formula which is volume=length times width times high.
A regular pentagon can always be drawn through any two given points  with those two points as any two vertices of the pentagon.  (Diagonals of a pentagon connect two vertices which are not next to  each other.)

In value, a penny is smaller. In size, a dime is smaller.
Only if the congruent angle is the angle between the two congruent sides (SAS postulate).
It is usually [Shift] [cos]   though on some calculators it may be [2ndF] [cos]    The arc cos function is often written as cos-1 or acos, and on most  calculators is written above the button to press; the colour of the  text used to write it usually matches up with the key needed to ...
I'm assuming you mean 33/12 12 go into 33, 2 times (because 2 * 12=24 without going over 33 ). So that33 - 24=9. Now2 9/12 reduce the faction down to lowest common fraction is 3/4We get 2 3/4 for a answerSince 2 3/4=11/4 so:11/4 * 3/3=33/12So 2 3/4 is the correct answerFor it
Multiplications and divisions first: 1 x 6/3 x 2=4 Additions and subtractions next: 12 - 4 + 1=9

you multiply acres (500 in this case) by 43,560 to get square feet.
Circumference is pi times diameter. If the radius is 24, the diameter (twice the radius) is 48, making the circumference 48pi, or approximately 150.72 units.
Data representation. Cumulative frequency is the sum of all previous frequencies.
A square meter is larger. A square yard consists of an area 3 feet by 3 feet, producing an area of 9 square feet. A square meter is an area roughly 3.28 feet by 3.28 feet, producing an area of roughly 10.76 square feet.
Approx. 7.87 inches, or two thirds of a foot.
If you're talking about two parrallel lines that have a line which  strikes through them then the term is congruent angles.
Work: don't care about time (that's power)   frictionless means don't care about length of plane   only care about height and mass -- figure 9.8 m/s*s for  acceleration of gravity   F=ma   F times distance (up)=work   good luck
The common factors of 18 and 45 are 1, 3 and 9.
Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.
1 acre=43,560 square feet 0.1 acre=(0.1 x 43,560)=4,356 square feet
Use proportions. 132/825=x/100.   132*100/825=16%
Calculating  concentration of a chemical  solution is a basic skill all students of chemistry must  develop early in their studies. What is concentration?
x - father's age   y - son's age     x=9y  x+5=4(y+5)    => 9y+5=4y+20=> 5y=15=> y=3    x=9y=> x=27
You have 15.2911 cubic meters. 1 cubic yard is equal to 0.764555  cubic meter.
No. 8.2 is smaller than 14.
Okay. The 'full amount' of something is one-hundred percent. Half  of one hundred is fifty. For example, if something costs  five-hundred dollars and it was on special in a shop, it would cost  two hundred and fifty dollars. So if an advertisement says  something is fifty percent off, it means...
First, convert the mixed measurement 3ft 2in into inches, making 38 inches. Then, multiply by 2.54 to get 92.52 centimeters.
his death was unspecified
3ft. in 1 yard.12in. in 1 foot.12 times 3 equals 36 inches.
No, it is not a prime number.
It is 4.   64 divide by 16 is 4
