Given numbers 1-9 and 4by4 squares,place the numbers so that the sum of horizontal,vertical and diagonals are equal.

Impossible (or wrong statement) : the diagonals in the corners are made of the sum of one and only cell. ; and this cell has to be added to the horizontal and vertical lines ; so the sum of these lines can only be superior to the value of the only-one-cell-diagonals.

Find missing number in this progression: 15 26 34 51 ? 84 96 125

The missing number is 61.
Look at perfect squares: (1,4,9),16, 25, 36, 49,64, 81,100,121
Then look at the given progression 15, 26, 34, 51, x, 84, 96,125
Take differences from the closest -1,+1, -2, +2, -3, +3, -4, +4

(15 is 1 less than 16 = 4 squared,
26 is 1 more than 25 = 5 squared,
34 is 2 less than 36 = 6 squared,
51 is 2 more than 49 = 7 squared,
61 is 3 less than 64 = 8 squared,
84 is 3 more than 81 = 9 squared,
96 is 4 less than 100 = 10 squared,
125 is 4 more than 121 = 11 squared)

Canoscan Lide 30 compatibility with Windows 7.

There are no official drivers for CanoScan Lide 30 for Windows XP, so your problem is obvious. I suggest you sending an e-mail at Canon including details about your scanner (date purchased, serial number in text form or scanned) asking them to develop driver set as this model is very trade and at shops since 2006 or 2007.

In case of a problem or clarification, don't hesitate to post.

Thanks and regards

How do i put the square root of a problem in a TI

Use the square root key accessed after pressing the [2nd] function key.

Press [2nd] [Square root key] 121 [ ) ] [ENTER]. Do not forget the right parenthesis, even if you did not have to enter the left parenthesis.
The result should be 11 (one of the square roots to remember).

Hope it helps.

Each diagonal of a square measures 1 inch. if the diagonals bisect each other and segments formed measure x/3 and 1 - x/6. what are the exact measures of the segments Enter Problem: Help Math...

If the diangonal of a square is 1, either side opposite the diagonal is equal to the sin of 45 degrees. sin 45=.70710678. The segments formed by the bisection of the diagonals would be one half the length of the diagonal which would be .5 x 1 = .5. Or you could take the sin of .70710678x.70710678=.5 for the bisectors.
(if I understand what you are asking.)
