You didn't iclude the figure.....need to know if the point given is in Q I    or   Q II

6/9 times 5/8  =  30/72  reduces to  5/12  or, in decimal form, 0.4166

D==Drummers,   F==Fifers

F / D ==7 / 1

[F  -  6] / [D  +  2] ==3 / 1, solve for D, F

D==3 - original drummers.

F ==21 - original fifers.

Oh, that wasy. i wonder why I got stuck lol.

Thanks :)

Just pic the point exactly between:    x   2 to 6         4

                                                         y   3 to 8          5.5

Sorry, I missed " express as fraction"

144 / 6! ==144 / 720 ==1 / 5

When the first is 5 and the 2nd digit is 6, you have: 1 x 1 x 4 x 3 x 2 x 1==24 such numbers.

When the first digit is 6, then you have: 1 x 5 x 4 x 3 x 2 x 1 ==120 such numbers.

24  +  120 ==144 integers > 550,000

What is the value of 21^2 + 22^2 + 23^2 + ... + 40^2 + 41^2 + 42^2?

Find z.

Hello Guest!

\(\dfrac{2 \sqrt{z} - 3}{\sqrt{z} - 1} + 1 = \dfrac{3 \sqrt{z} - 1}{1 - \sqrt{z}}\\ \dfrac{2 \sqrt{z} - 3}{\sqrt{z} - 1} + 1 = \dfrac{1-3 \sqrt{z} }{\sqrt{z}-1}\\ 1= \dfrac{(1-3 \sqrt{z})-(2\sqrt{z}-3) }{\sqrt{z}-1}\\ 1=\dfrac{4-5\sqrt{z} }{\sqrt{z}-1} \)

\(\sqrt{z}-1=4-5\sqrt{z}\\ 6\sqrt{z}=5\\ \sqrt{z}=\dfrac{5}{6}\)

\(z=\dfrac{25}{36}\)

  !

Multiply R side by   -1/-1   then eliminate the denominator from both sides to get:

2 sqrt z - 3  +sqrtz -1   = 1-3 sqrt z

6 sqrt z = 5

sqrt z = 5/6

z = 25/36

The number of units sold is dependent on the price

   starts at 24     with price   8

       as price rises by 1      units goes down by 3

             units sold then becomes   (24 - 3(x-8) )     =  48 - 3x

                   PROFIT is  number of units sold * price   - units sold * cost

                                              (48-3x)             * x          -    (48-3x) *   4            <=====simplify this

                                                    -3x^2 + 48x            -192 + 12x

                                a)      PROFIT = -3x^2 + 60x - 192    

                                b)   Max occurs at - b/2a =  -60 / (-3*2)  = 10 dollars  price

                                c )  -3(10^2) + 60(10) - 192 = 108 dollars  profit                                              

There are 9C3 = 84 ways to choose 3 dots.

There are  8 ways that those 3 dots  can all be in a row.

So

I think that there are  84-8 = 76 different triangles that can be formed.

each piece

sqrt 169 = 13

sqrt2 sqrt6   =  2 sqrt 3

sqrt 110 = sqrt110

26 sqrt3 sqrt 110

26 sqrt 330

26 sqrt (3  11   5   2  )         ( cannot reduce  further to integer values)

26 sqrt ( 330 )

Work = f X d

         = 186(.43)(7.2)     N-m

Using conservation of momentum

Original momentum = 0

final total momentum = 0

(mv)_b  = (mv)_g

721/9.8 * .470    =   484/9.8  * v_g

(721 * .470) / 484   =    v_g       in  m/s

Where is the pic?

1 chain = 22*3 feet

so the area is  (22*3)*10  square feet

Multiplying by a constant does not change the degree of the polynomial... 

So degree of.  f+ a* g. would still be 8

Max would be 2.05*2.   *  2.05*3.  *   2.05. m³

I meant congruent!!!

M => 4x           N => 2x           O => x

M : N : O = 4 : 2 : 1

x / 4x + 58 = 1/5

x = 58

Hint: angles XYW and XWZ are similar!!!

DF / 2 = 7 / 5
