Unfortunately, the browser used by Answers.com for posting questions is incapable of accepting mathematical symbols. This means that we cannot see the mathematically critical parts of the question. We are, therefore unable to determine what exactly the question is about and so cannot give a proper answer to your question.

Remember K H D | d c m. Metres is three places to the right of Kilometres. So you have to move the decimal place three times to the right. So in this case the answer is 1000 metres.

No - 4/12 = 0.3 recurring (that is, 0.3333...) while 12/4 = 3.

Squares.

(y + 30)(y - 1)

Yes

= 2 + 64 + 4 = 70

7 and (-3/2)

x2+x-6=0

* * * * *

Perhaps the solution you are looking for is:

x2 + x - 6 = (x - 2)(x + 3) = 0;

whence, x = 2 or -3.

40 is a rational number, so the question is misguided.

3y=ab. Divide by 3 to get y=ab/3

This isn't a proper question! I think you mean "minimizes the amount of METAL used to make the can" ....

Even this isn't a question.

However, the minimum ratio of surface area to volume - i.e. used the least metal/ aluminum etc - will be a sphere. Not very useful for a drinks can though?

y=4x2+3x+8

x equals 19

do you mean x=3(2y-1)+2?

if so, (x-2)/6=y

here are the steps:

x-2=3(2y-1)+2-2

(x-2)/3= (3(2y-1))/3

((x-2)/3)/2=y

(x-2)/3/2 also equals (x-2)/3 * 1/2

6

2x + 3 = 9x start by bringing the 2x over- minus it from both sides

3 = 7x divide 7 by on sides

x= 3/7

x = .4285714285714 repeating. :)

The digits of pi are not periodic. Pi is an irrational constant, and if its digits were periodic, it could be expressed as a ratio of constant integers, meaning it would be rational.

[ (x - 4) / 15 ] / [(2x + 13) / 15] = (x - 4) / (2x + 13)

300 millimetres = 30 centimetres.

1,1x = 97186

x= 97186/1,1 = 88350,9

4' 3" = 51" x 2.54 = 129.54cm

From solid to liquid,liquid to a gas, solid to a gas is called sublimation. Generally it requires adding or giving out energy depending which direction it is going.
