Thanks so much CPhill..

I couldn't solve that one at all...

😏😏

For the first draw.....we can get anything

For the second draw...we have a 3/4 chance of getting a different suite from the one on the first draw

For the third draw, we we have a (2/4) chance of getting a suite different from the first two

Finally.....on the last draw....we have a (1/4) chance of getting a different suite from the first three

So....the probability is

(1) (3/4) (2/4) (1/4)   =    6 / 64   =   3 / 32

You're welcome, all of you

  XD Nickolas? But I am very obliged to your contributation to help me understand this concept better : )

Thanks, everythinguniversal   !!!!

This one is a little dificult, Nickolas....

We need to put every thing in terms of yards and then solve for the width

8 ft  =   96 in  / 36 in  =  8/3 yds

4 in  =   4/36   =  1/9 yds

So 

Length * Height * Width = Total Volume  ....so.... 

L * H * W  =  Total Volume

(8/3) (1/9) * W   =

(8/27) * W

Total cost  =     Total Volume * Cost per cubic yard

( Note that W will be in terms of yards )

58.07  = [ (8/27] * W * 98 

58.07  = W * [8/27] * 98

58.07  = W * [ 784 / 27 ]                 multiply both sides by   27 / 784

58.07 * [ 27 / 784 ]  =   W ≈  1.999   =    2 (yards)   =   6 feet

You probably have some questions about this one....it's harder than the others you have submitted

Thank you alot for your help I starting to get what needs to be thanks for your spent time : )

Convert first the cost of 98 /yd³ by the conversion factor that 1 yd³ = 27 ft³.
                           (98 /yd³) (1 yd³ / 27 ft³) =  3 17/27/ft³
Let x be the width, the volume of the rectangular portion of the driveway is,
                           V = (8 ft) (1/3 ft) x = 8x/3 ft³
Using the given total cost of the protion,
                                  C = $58.07 = (8x/3 ft³)($ 3 17/27/ft³) 
x = 5.99957 ft
Thus, the answer is d. 6 feet.

D. 6 feet is correct.

XD Oh gosh man I wish I remembered the formula for that XD Thanks calculator user!

lol

  you guys dont need these complicated methods of solving. For any parrelelgram you do:

So you just B * H = A

6 * 8 = 48

I think Hylin link did a great job doing it the other way as its easier to understand.

The expression (1/2)*b*h refers to a single triangle. 

The kite can be considered as two large triangles of base 19in and height 9.5in; or four triangles, two of base 12in and height 9.5in, and two of base 7in and height 9.5in.

Hence you should double your result of 90.25 in².

Oh yeah.. 

Yes, I see that all those empty answers you gave and half posted questions were proably one special addition the forum XD ; )

My piggle acount 

If you have no option it seems you will have to round the number...

Cphill answered 71 someting I have no option for that....
