53 * ( pi * 837.0069km )  will give you your answer....

Thanks, geno....I'll recommend this one for Melody's Daily Wrap...!!!!

Just playing around with this in WolframAlpha, I noticed that...

floor(x)*(x) = 91 returns the solution  -91/10

but

floor(x)*(x) = 101  returns the solution 101/10

and

floor(x)*(x) = 122  returns the solution  122/11

but

floor(x)*(x) = 143  returns the solution  -143/12

I wonder if there's some rationale for the fact that, depnding on the number on the RHS of the equation, the parity of the solutions seems to "oscillate" ???  .... anybody ????

Ohh that makes much more sense! You're good at explaining than my math teacher. Now I can finish the rest!

The factors of 24 are:

   1 x 24

   2 x 12

   3 x 8

   4 x 6

A linear equation (straight line). 

-4(3x - 5) > -28

Use the distributive law on the left side:

(-4)(3x) - (-4)(5) > -28

-12x + 20 > -28

Subtract 20 from both sides:

-12x > -48

Divide both sides by -12:

(When you multiply or divide both sides of an inequality by a negative number, you must change the direction of the inequality; you don't change the direction if you are adding or subtracting or if you are multiplying or dividing by a positive number.)

x < 4

√(90) · √(14) · √(70)    

Factoring these, you can get:

=  √( 9 · 10 · 7 · 2 · 7 · 10 )

Rearranging:

=  √(9) · √(10 · 10) · √(7 · 7) · √(2)

=  √(9) · √(100) · √(49) · √(2)

= 3 · 10 · 7 · √(2)

=  210√(2)

If the function is:  g(x)  =  -2x - 1,

then                    g(-3)  =  -2(-3) - 1  =  5

An equation for the situation where you are paid $500.00 plus 4% commission on total sales will be:

     y  =  500.00 + 0.04x

The other equation will be:  y  =  $400.00 + 0.05x

When graphed, the first equation has a higher y-intersect but a smaller slope.

Their intersection point can be calculated by setting the two equation to each other{

     500 + 0.04x  =  400 + 0.05x

     100 + 0.04x  =  0.05x

                  100  =  0.01x

--->   x  =  $10,000.00

Therefore, on total sales less than $10,000.00 the first situation is better ($500.00 plus 4% commission on total sales); over $10,000.00, the second situation is better; at exactly $10,000.00 they yield the same amount.

You need a number such that  x  and the  integer value(x)  when multiplied will give you 27.

If the answer is a perfect square, then the square root will be your answer.

Since 27 is between the perfect squares 25 and 36, the answer will be between their square roots, 5 and 6.

The integer value of a number between 5 and 6 is 5, so now you are looking for a number x that satisfies the equation:  x · 5  =  27                      (because 5 will be the integer value of x)

Solving this, you get  27/5  =  5.4

Well 100 percent of 25 is 25 and 100%/5=20% so 25 + 5 = 30 and 100% + 20% = 120% so 120% $${\mathtt{30}} = \left({\mathtt{25}}{\mathtt{\,\times\,}}{\mathtt{p}}\right) \Rightarrow {\mathtt{p}} = {\frac{{\mathtt{6}}}{{\mathtt{5}}}} \Rightarrow {\mathtt{p}} = {\mathtt{1.2}}$$ or 120%

$$21$$

$$30 percent of 25 is 7.5

just do: 25 x .3 = 7.5$$

It is called the "radicand."

√[(-33--18)^2+(5--6)^2] =

√[-15)^2 + (11)^2] =

√(225 + 121) =

√346 = about 18.6

LOL 

((a')!+(b')!+(c')!)!! / 12 + d' + e' + f'

where letters a - f are distinct natural numbers less than 20 and 12 is not in {a, b, c..., f} 

Works every time.

a*b = a - b + a - b

12*3 = 12 - 3 + 12 - 3 =  ?

10*5 = 10 - 4 + 10 - 5 = ??

Then subtract ?? from ?

a*b=a-b+a-b. How much larger is 12*3 than 10*5?

Using the relation as defined, we have

12 - 3 + 12 - 3  = 18    and    10 - 5 + 10 - 5  = 10

So 12*3 is "greater" than 10*5  by 8......

good how r u

12 divided by 6 would be 12/6

We would write the domain as  (-∞,-4) U (-4, -2) U (-2,∞)

I'm not sure how to solve this algebraically, but WolframAlpha gives the answer as 27/5 = 5.4.....this males sense because (27/5)* floor(27/5)  = (27/5) *(5)  = 27

(Maybe another forum member can show a "mathematical" way to solve this....!!!)
