It depends on what time of day it is, whether he's chucking evening wood or morning wood.  

A blonde and a brunette are standing on opposite sides of a river. 

The brunette shouts, "How do I get to the other side of this river?"  

The blonde replies, "You are on the other side of this river!" 

Ooops!    My error....thanx , Textot !

Missing some info.......

#3 Close, but you're confusing diameter with radius.

The answer would be $\pi\cdot \frac{1}{2}\cdot(3^2-1^2-2^2) = \pi \cdot \frac{1}{2} \cdot 4 = \boxed{2\pi}$

1 - tanx * cos x  /  csc x   =

1  - (sin x / cosx)  (cos x)  / ( 1 /sin x)  =

1 - (sin x)  *  (sin x)  =

1  -  sin^2  x   =        cos^2 x

Semi circle areas are   1/ 2 pi r^2     

   calculate the largest one (r = 6)  ....and subtract the two smaller ones ( r= 2 and 4)

1/2 pi  (   6^2   - 2^2 - 4^2)

1/2 pi ( 16) = 8 π   units²

Thank you so much have a good day 

What is the sum of all possible values of x such that 2x(x - 10) - x(x - 5) = -50?

2x^2 - 20x -x^2 + 5x = -50    simplify

x^2 -15x + 50 = 0     factor (or use Quadratic Formula)

(x-10)(x-5) = 0

     x = 10   or  5             add 'em......

Stefan borrowed $8,950 for an engagement ring. At a 6% simple interest rate, how much interest will he have paid after 18 months?

18 months is 1.5 years    interest is .06

.06   *  8950 * 1.5 = interest = $            

Stefan borrowed $8,950 for an engagement ring. At a 6% simple interest rate, how much interest will he have paid after 18 months?

17% is .17 in decimal form

.17 * 22983 = commision = $              

0.5592 

although you could just use the calculator

Good grief....just use the calculator....

Could you please clarify? Thanks!

That is incorrect.

The area of the blue region is pi.

Using the quadratic formula, $A = \frac{-1}{3} + \frac{\sqrt{10}}{3}$ and $B = \frac{-1}{3} - \frac{\sqrt{10}}{3}$. Try to do the rest on your own.

Very nice, Melody   !!!!

I  think  that  this is    

4 sin  x   - 1   =   0      add 1 to both sides

4sin x  =  1                 divide both sides by 4

sin x   = 1 / 4             take the  arcsin

arcsin ( 1/4)  = x  ≈  14.48°  +  n*360°

And      x  =    165.52°  + n*360°        where n is an  integer in  both cases

Well....

   As much wood, as a woodchuck would, if a woodchuck could chuck wood.

4/6     6/9      8/12    etc  

or   .66666666........

1/5 meter = 200 cm

   there are 4 sides added together to find the perimeter:

200 cm / 4 sides = 50 cm/side = .05 m / side

Let's say there is 100 to start with  (as in 100%)

10 = 100 (1-.4)ⁿ     where n is the number of years after 2004 to reach 10%

10/100 = (1-.4)ⁿ

.1 = .6ⁿ 

log .1 = n log .6

n = 4.51    years to reach 10%

  this will be in VERY late  2008      but I bet they say it is 2009   because it askes what year the census will show <10%......there will be no new census until 2009 .......   kinda tricky, huh?
