Doing fine you? :3

By Euclid Book VI Proposition 3, we have that

 AF/FB  = AC/ CB →  x/ [8-x]   = 10 / CB    (1)

Also 

EC / EA   = BC / AB  →  4/6 =  BC / 8  →  BC = 32/6  = 16/3      (2)

Substituting   (2)  into (1), we have that

x / [8 - x]  = 10/[16/3]    cross-multiply

16x/3   = 10 [8 -x]

16x = 30 [ 8 - x ]

16x  = 240 - 30x

46x  = 240 

x = 120/23 = AF

8 - x = BF =  8 - 120/23  = 64/23

Thats amazing!

7/8 is real and it is rational

a(-1)

No calculation character between a and (-1) is  * (multiply).

a(-1) = a * (-1) = - a

Let

x = no. of cows

y = no. of pigs

Z = no. of chickens

And we have the two equations

x + y + z = 100   

10x + 3y + .50z = 100

Since we have more variables than equations, we have multiple possibilities......here's one:

x = 5  = no. of cows

y = 1  = no. of pigs

z = 94  = no. of chickens

what is .8% of 120?

.8% = 0.8%

Simply multiply

120 * 0.8% = 0.96

what is .8% of 120

Let the number =x

0.9235x =128 divide both sides by 0.9235

x =128 / 0.9235

x =138.60 would be your 100%

8:2/3 = ?

The Walker family and the Goodman family are going to the cinema. The Walkers pay £22 for 2 adult tickets and 1 child ticket. The Goodmans pay £26 for 1 adult ticket and 3 child tickets. 

Let adult tickets=A

Let child tickets=C

2A + C =22

A + 3C=26, solve for A, C

A=8 pounds each.

C=6 pounds each.

They are numbers that can reprensented by a fraction.

Like integers, REPEATING decimals, terminating decimals, and fractions

Below is defin.

12 - (-9)

= 12 + 9

= 21

 2 * -1 + 3

= -2 + 3

= 1 :)

circumference means the perimeter of circle.

Circumference = pi times diameter.

Also Guest #1, Circumference does not equal area divided by pi.

\(\text{Circumference}=\dfrac{2\times\text{Area}}{\dfrac{1}{2}\times\text{Diameter}}=\dfrac{4\times \text{Area}}{\text{Diameter}}\) instead.

0/0 will give you a MATH ERROR on a calculator but 0 x 0 won't.

0 x 0 = 0

If you want to present 0 x 0 to the calculator on this site, use 0*0.

* can be typed by pressing the '8' button on your keyboard above the 'i' button when holding shift. Or you just find the * symbol on the calculator.

m8 is m8 LOL.

m = 8, m8 = (8)(8) = 64.

Firstly, half of 9 is NOT 3.

Secondly, if you replace the 1 with x in '13' that would just be x3 and that means nothing and that doesn't mean x = 3.

Lastly, if you really got x = 3, that doesn't mean a triangle, and that doesn't mean the illuminati.

Therefore, your statements are false.

pi is the ratio between the circumference of a circle and the diameter of the SAME circle.

pi is the ratio between the circumference of a circle and the diameter of the SAME circle.

And I think that wasn't calculus and it is statistics instead??

False.

\(\left(\dfrac{5}{9}\right)^2\\ =\dfrac{5^2}{9^2}\leftarrow\boxed{\left(\dfrac{a}{b}\right)^m=\dfrac{a^m}{b^m}}\\ =\dfrac{25}{81}\)
