The minute hand moves 1/5 of 360 degrees in 12 minutes. (12 minutes / 60 minutes = 1/5)

So......(1/5) * 360  = 72 degrees

I use a program called Malwarebytes to scan for viruses....it even has a feature that "sidesteps" viruses that try to prevent you from accessing virus protection software. After a scan, if something is found, it will allow you to quarantine it.

Your problem sounds like mine.....I ran a REALLY old HP (circa 2003) up until this Feb. It had an XP operating system and I had to recover from "crashes" at least 3 times...but, after awhile..it just wasn't worth it and it finally conked out!!

I suspect that you're going to be better off buying a new laptop (or something comparable). I'm running Windows 8 and I can tell you the difference is night and day between this Samsung laptop and that old HP desktop computer. I've had "zero" virus problems.......

If you can hold off, Windows 9 is in the works....it's supposed to be better than 8....!!!

Sorry for your computer ptoblems......

I'll do everything in inches

(10 cm = 3.937 in)

So A is

10 * 6 * 3.937 = 236.22 cu. in.

B is

15 * 14.44 = 216.6 cu. in.

C is

(volume of water = ht. of water * area of the base).......  therefore.......

(volume of water/ area of the base = ht. of water)

216.6 cu. in / 60 sq. in =

3.61 inches

(1)       2,8,25,50,75,100  Magic number is 431   (This one is very hard)

If we don't have to use every number, here's a solution:

8 (50 + 75/100) + 25 =

400 + 6 + 25 =

431

Eh....not necessarily better....just different........we would have both arrived at the same train station......so to speak......

Thanks, TM....!!!.......I always like to provide  a little humor when I can......

BTW.....I gave everyone 3 pts on this one.......

Sin is getting too much of a Tan, Cos you forgot to use sunscreen......

Any odd integer can be expressesd as 2n-1 where n = 1, 2, 3......

So, let the first odd integer be 2n-1, the next one 2n+2, and the last one 2n+3.

So

(2n-1) + (2n+1) + (2n+3) = 63     and simplifying, we have

6n + 3 = 63  

6n = 60

n=10

So

The first integer is 2(10) - 1 = 19

The next one is 2(10) + 1 = 21

And the last one is 2(10) + 3 = 23

And that's it!!

I assume this might be

What is 2 (4h-5) ÷ (-6 + h) for h = 2 ???  So we have...

2(4(2) - 5) / (-6 + 2) =

2(8-5)/ (-4) =

2(3)/ (-4) =

6/-4  =

-3/2

So I assume we have

3(-5/3)^-4 ??

If so, we can wrie this as

3* (1/(5/3)⁴) =

3* (3/5)⁴ =

3 (81/625) =

243/625 or .3888 in decimal form
