To make a mesh every 5 cm on the 5 meter side (that is, going down):  change the 5 meters into cm, giving 500 cm.

Divide 500 cm by 5 cm, giving 100 ---> however, you must add 1 to get the correct number of threads.

Each of the 101 threads is 2 meters long ---> 202 meters.

To make a mesh every 5 cm on the 2 meter side (that is, going across):  change the 2 meters into cm, giving 200 cm.

Divide 200 cm by 5 cm, giving 40 ---> again, you must add 1 to get the correct number of threads.

Each of the 41 threads is 5 meters long --->  205 meters.

Adding, you will need at least 407 meters of cord.

50  =  x(2x + 3)

50  =  2x² + 3x

0  =  2x² + 3x - 50

Quadratic formula:  x  =  [ -b ± √( b² - 4·a·c ) ] / ( 2·a )

a = 2          b = 3         c = -50

x =  [ -3 ± √( 3² - 4·2·-50 ) ] / ( 2·2 ) 

x  =  [ -3 ± √( 409) ] / ( 4 )     4.30...   or   -5.80...

Hi Rosala,

It is great that you are back :)

We have all missed you!   :))

(21/30) x 90  =  (7/10) x 90  =  7 x (90/10)  =  7 x 9  =  63

If a triangle has an hypotenuse, it must be a right triangle.

If a right triangle has one anlge of 45°, the other acute angle must also be 45°.

Therefore, the triangle is an isosceles right triangle.

One way to solve this is to use the Pythagorean Theorem:  a²+ b²  =  c²

c is the hypotenuse   --->   c = 10

Since it's isosceles, a = b, call each one x:     x² + x²  =  10²

                                                                   2x²  =  100

                                                                     x²  =  50

                                                                       x  =  √50  =  √25√2  =  5√2

2x  =  10 - y

y - x  =  -2     --->   (solve for y)   --->   y  =  x - 2

Replace this into the other equation:  2x  =  10 - (x - 2)

                (distribute)                           2x  =  10 - x + 2 

                (add x to both sides)            3x  =  12

                (divide by 3)                           x  =  4

Replace this into the equation  y  =  x - 2     --->     y  =  4 - 2     --->     y  =  2

Are you doing it by computer or by calculator?

If computer, what program are you using?

If calculator, what calculator are you using?

One answer:  -52.07 radians (approx)

Graph it.

(2/(-8+6))^8      OK.... we have

(2/(-2))^8  =

(-1)^8 =

1

That was pretty easy, huh??

well if it is 2 and a half times bigger that is 250%

Ok I appologise.  I see what you are saying :)

We're not talking about a repeating pattern....we're talking about any random finite string of digits being found within pi. It is well established that pi itself is irrational....i.e, no general repeating pattern....

There can not be a pattern Chris because if there was pi would not be an irrational number. !

A 50% increase means that every dimension increases  1.5 times its original length....

no it is not happy

1 divided by infinity=0      

$$\\2x-9+47+x=180\\
3x+38=180\\
3x=180-38\\
3x=142\\
x=142/3\\
x=47\frac{1}{3}$$

-100 - 3x  =  -9x + 26

Add 9x to both sides:

-100 + 6x  =  26

Add 100 to both sides:

     6x  =  126

Divide both sides by 6:

   x  =  21

Not even close to infinity!

0.8(12.5x + 7)  =  2(5x + 11)

Distributing:

10x + 5.6  =  10x + 22

Subtracting 10x from both sides:

    5.6  =  22

Impossible!  This is not an equation ... No answer ...

If the scale factor is 2.5, then every dimension (length, width) is multiplied by 2.5.

(16+1-15)v=14

2v=14

v=7

look at this post

Two thirds plus 6 equals 6 and two thirds.

That looks like fun Chris :)

i have no idea what you're talking about with your kittens and dogs.  :)

Would you like to explain?  :))

30% written as a decimal is 0.30

"of" is interpreted as "times"

30% of $50,000.00

0.30 x 50000  =  ???
