Volume of  fish tank  = 60 x 45 x 30  = 81000 cm^3

20 sec  = 1/3 min

9L   = 9000cm^3

So

81000 / 9000  x (1/3)min  =    

9 * (1/3)  min  =

3 min to fill the tank

Web2.0calc.com has a built-in calculator for your convenience.

Sorry, you want 7/9(-0.26)(9/7)? Or... 7/9(-0.26)?

7/9(-0.26)(9/7) = -0.26

7/9(-0.26) = 91/450 or .2022222222222

If that doesnt help, tell us what the question is again

Wow....that's hard on the eyes...!!!

1 min = 60 sec = 3 *20 sec....so 3 *9   = 27 L

There are 2 possibilities for each coin.....so......the number possible arrangements of heads and tails  =  2⁸   =  256

Correct. If Sally's friends give 1/6 more apples then she haves. How many does she have now?

Rewrite the decimal number as a fraction with 1 in the denominator. e.g 2.625/1 

Multiplying by 1 to eliminate 3 decimal places, multiply top and bottom by 10(3)= 1000. e.g 2.625 x 1000/1000= 2625/1000.

Find the GCF of 2625 and 1000, if it exists, and reduce the fraction by it, GCF = 125. e.g 2626/1000 / 125/125 = 21/8.

Then simplify the improper fraction. 21/8 = 2 5/8.

Therefore 2.625 = 2 5/8 (I'm only in grade 5 so sorry if you did not understand this.  I'm kinda smart for my age)

Hi EP, your one might have had its roots exposed, but my one grew square roots   

Yeah, it doesn't work for me either, thanks for letting me know that its not just my computer!

The fractions input helper has never operated for me  YMMV....   click on the little gray bars in the display area to find the fraction helper....

It had it 'roots' exposed?

If you rewrite the FIRST equation    x = 9 + 3y     substitute this value of x into the second equation

x + 4y = 2

9+3y+4y=2

7y = -7

y=-1         Substitute this into one of the original equations to find x

x - 3 (-1) = 9

x +3 = 9

x = 6

To ADD or SUBTRACT fractions you must have a common denominator   .....   12 x 7 = 84   we can use

11/12 = 77/84   and  3/7 = 36/84

(77 + 36) / 84 = 113/84 =  1  29/84

Hmmmm....   is the smaller sector CENTERED within the larger ?   Maybe?  I think I can solve it if it is centered.....   DO you have a diagram?

What equation are you referring to? You don't seem to have any equation in your post.

Assuming 6 laps is a mile     8 minutes / 6 laps =  1.333 minutes per lap   or 1 minute 20 seconds per lap.

Unless you know what x equals, x - x (or, if it is easier for you to think of it this way, 1x -1x) equals 0. (zero)

1,736,654,567 + 3,345,746,384 = 5,082,400,951

It is 4 PS tell Annabelle that is too much juice

Are 20 and 9 both negative, or is 20 just negative and 9 positive, or 9 just negative and 20 positive? I need more information to answer this question.
