The volume of a square pyramid is given by

V =(1/3)* pi * s^2* h         where s is the side length and h is the height......so we have

1024 = (1/3) (3.14) (s^2) (12)   simplify

1024 = 12.566 *  s^2         divide both sides by 12.566

1024 / 12.566  = s^2         take the positive root of both sides

s = 9.03 inches

Type 

log(7, 14)        [ where 7 is the antilog and 14 is the base  ]

 7(2-m)-11=-4        add 11 to both sides

7(2 - m)   = 7         divide both sides by 7

2 - m =   1              add m to both sides and subtract 1 from both sides

1 = m 

Check

7(2 - 1) - 11  = -4

7(1) - 11 = -4

7 - 11  = -4

- 4 = -4   .....which is true

The points stuff is just something here for fun, MG1......I told Melody that I don't care if I have any points or not....

But......some people like them......they only add to your score....too bad we don't get any money for them....

LOL!!!

65% =  65 / 100 =  [13 * 5 ] / [20 * 5 ]  =  13 / 20

Maybe Google removed them.........

Type in  "3 - 3 "

Because 6 divides both 6 and 12, MG1......

Let n be the number ... so....

n + 18  = 3n - 8      add 8 to both sides......subtract n from both sides

26  = 2n                  divide both sides by 2

13 = n

Yep......

You have too much free time on your hands, Melody.....

LOL!!!!
