Rate x time = distance    (Or amount burned)

rate1   =   1candle/6hr= 1/6

rate 2 =   1 candle/ 4 hours = 1/4

amount remaining after x hours = 1 candle - rate * x

1- 1/6 *x  = 2 (1- 1/4 * x)

1- 1/6 x = 2 - 1/2 x

1= 2/6 x 

x = 3 hours

  ( I couldn't find the other posted answer)

3 hrs  x  1/6 =   1/2  Burned  =  1/2 left

3 hrs x1/4 = 3/4       Burned   = 1/4 left 

its ok, thanks tho

69 has another meaning that you probably don't want to know.

One way (and I don't claim that this is the easiest way):

Draw a line segment from A perpendicular to CD ending at point X on CD.

Draw a line segment from B perpendicular to CD ending at point Y on CD.

You now have triange(ADX), rectangle(AXYB), and triangle(BYC).

Combine triangle(ADX) and triangle(BYC) so that points A and B coincide and points X and Y coincide, creating a triangle

with sides of lengths 13, 15, and 14.  [CY + DX = CD - 10 = 14]

Using Heron's formula to find the area of this new triangle:  s = (13 + 14 + 15)/2 = 21

--->     Area  =  sqrt[ 21(21-13)(21-14)(21-15) ]  =  84.

To find the height of this triangle (which is the width of the rectangle):

--->     Area  =  ½·base·height     --->     84  =  ½·(14)·height   --->     height  =  12.

Therefore, the area of the rectangle is:  10·12  =  120

and the total area is 84 + 120  =  204

I go to Texas for a week and when I come back the question is changed?  I will remember your name, guesttttt with 5 t's.

Umm... what?

If it is a linear function, it must have a constant slope:  m  =  [ y₂ - y₁ ] / [ x₂ - x₁ ]

For this problem:  if  x₂ = 6  and  x₁ = 2,  then  y₂ = f(6)  and  y₁ = f(2)

     --->     m  =  [ y₂ - y₁ ] / [ x₂ - x₁ ]     --->     m  =  12 / [ 6 - 2 ]

                                                             --->     m  =  12 / 4

                                                             --->     m  =  3

--->     m  =  [ y₂ - y₁ ] / [ x₂ - x₁ ]     --->     3    =  [ f(12) - f(2) ] / [ 12 - 2 ]

                                                        --->     3    =  [ f(12) - f(2) ] / [ 10

                                                        --->     30  =   f(12) - f(2)

69 nice hehehe

Sorry for bothering you again! Should I split the triangle in half, and use pythagorean therom? If so how do I found out the height? 

np lol

Oh haha thank you! That makes a lot more sense now! 

The radius is sqrt(2(10^2)) = sqrt(200) since one edge is the center and the other the edge.

Thus, 200π is the area, /4 is 50π.

The square is 100

50π-100 is your answer.

If you don't understand anything feel free to ask.

hmm I dont really see your logic behind that answer

The vertex of the parabola is (4,-6).

a + b + c = 3*13 = 39.

Arc TU = 4*26 = 104 degrees.

I've tooken a look at purplemath and I have a khanacademy account when I was 5.They are all great websites I learned to code with scratch when I was young and now i'm doing khanacademy for history, ELA, and math

I will agree to help solve any problems but people should stop arguing whenever there is a conflict this ebsite is for answering questions anyways I will help no matter who the poeple are I won't be mean and argue but I don't really like to argue with someone because it is bad for us both because we both lose points and have anger which is bad
