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.

If the zeros are significant figures then 900 is correct to 3 significant figures. If rounding off has occurred then the answer could be 1 sf or 2sf. For example : If the original number was 903 and rounding off to the nearest ten was required then 900 is correct to 2 significant figures. If the...

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 =...

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 thevehicle's fuel efficiency (MPG) and how much local gas cost whereyou'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 thisinstance, 0.05 x 105 = 5.25. Therefore, 5 percent of 105 is equalto 5.25.

The radius is tripled, too. Suppose: (1) C = 2Ïr (2) C' = 2Ïr' (3) C' = 3C Then C' = 3(2Ïr) = 2Ï(3r) But C' = 2Ïr', so 2Ïr' = 2Ï(3r) and finally r' = 3r.

Length is usually left to right, and the side that is not theheight or length is the width.

The radius is directly related to the circumference of a circle by C=Ï 2R so it would get proportionately larger as the circumference grows. If you start with C=Ï 2R where 2R=C/Ï then change C to C 2 =3C then 2R 2 becomes C 2 /Ï or 3(2R)/Ï

You need to know the density o f Mg D = Mass/Volume Mass = Density * volume Density= 1.74 grams per cubic centimeter Volume = 2.5 * 3.5 * 1.5 Mass = Density * volume

A straight edge is basically another name for a ruler, or it couldbe 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...

The ratio of the chance of that event happening divided by all possible events. Chance of rolling a 6 is 1 (only one side has a 6) divided by the 6 possible events.

one way is you could get rid of the fraction by the multiplyingeverything denominator of the fraction and then just solving itregularly.

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...

If: n squared = 10n+56 Then: n squared -10n -56 = 0 When factored: (n-14)(n+4) = 0

Absolute value can be defined as the distance from the expressionto 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

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 dimension 88 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...

4 out of 5 is 80%. You can figure this out by taking 4 and dividingit by 5, which is 0.8, which is 80%. Or you can multiply 5 by 20 toget 100 and then multiply 4 by the same number which gives you 80,that would give you 80/100 or 80%.

Digits that are powers of primes are 2 2 = 4, 2 3 = 8, and 3 2 = 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 2 2 =4, 2 3 =8, 2 4 ...
