1/3 or 1 over 3

√8   =

√ [ 4 * 2 ]  =

√4 * √2    =

2*√2

Mean   =  [ sum of values ] / [number of values ]   ...  so..

 35  = [ 28 + 40 + 36 + 47 + 33 + X ]  / 6      multiply both sides by 6, simplify

210  =   184  + X     subtract 184 from both sides

26  =  X

3 times the 5th root of 3?

I guess you just have to search that up!

\(\pi * d\)

\(\pi *6\)

\(6\pi\)

6π feet!

Of course, this is assuming that you're talking about a circle.

Maybe it is a problem with tinypic ??

Yes it is a problems with Tinypic !! 

I usually get my picture addresses either straight from the original on the net or I use Gyazo.

Gyazo is like Tinypic, It is just a different storage provider. (my wording is probably inaccurate)

ANYWAY, TINYPIC IS NOT WORKING PROPERLY.

volume of cone = (1/3) * pi * radius² * height

radius = diameter/2

radius = 3/2  inches

volume of cone = (1/3) * pi * (3/2)²  * 5

                         = (1/3) * pi * (9/4) * 5

                         = (15/4)pi

                         ≈ (15/4)(3.14)    =    11.775   cubic inches

Let  x  =                  1        

                          1 +    1    

                                  2 + ....

So  we have that 

x   =     1 / [ 1 +  1/ ( 2 + x) ]

x  =  1(2 + x) / (2 + x + 1)

x =  (x + 2) / (x + 3)

x (x + 3)  =  x + 2

x^2 + 3x = x + 2

x^2 + 2x - 2  = 0

Taking the positive solution, x = √3  -  1

Thank you so much!

a)

area = length * width

x² + 7x + 13  =  (x + 4) * width                 Divide both sides of the equation by (x + 4) .

(x² + 7x + 13)/(x + 4)  =  width                 We can do this using long division....

So we get that

width  =  \(x+3+\frac1{x+4}\)

b)

perimeter = 2[ length  +  width ]

7 = 2[  x + 4  +  x + 3 + \(\frac1{x+4}\)  ]              Divide both sides by 2 .

3.5 = 2x + 7 + \(\frac1{x+4}\)                               Subtract 7 from both sides.

-3.5 = 2x + \(\frac1{x+4}\)                                    Multiply through by ( x + 4 )

-3.5(x + 4) = 2x(x + 4) + 1

-3.5x - 14 = 2x² + 8x + 1                      Add  3.5x  and  14  to both sides.

0 = 2x² + 11.5x + 15                             We can use the quadratic formula to solve for x.

\(x = {-11.5 \pm \sqrt{132.25-120} \over 4}={-11.5 \pm 3.5 \over 4}=-2.785\pm0.875\)

So, we get that  x = -2     and     x = -3.75

So......if x = -2

length = -2 + 4    =    2

width  = -2 + 3 + 1/(-2+4) = 1 + 1/2    =    1.5

And....if x = -3.75

length = -3.75 + 4    =    0.25

width  = -3.75 + 3 + 1/(-3.75+4) = -0.75 + 4    =    3.25

Hey, Davis!

thank you, I just was wondering how much my favorite soccer player made. 

$3,100, 000  / 365   ≈  $ 8493.15   per day

Smart-Aleck answer.....none!!!!

"Math" answer   =   "three"

30 / 8   =    3 + 6/8  =  3 + 3/4

The degree of a polynomial in one variable is determined by the  highest power exponent on that variable....thus....2nd degree

Volume_prism  =  base area * height  

So

84 =  base area * 12    divide both sides by 12

7 cm^2  =  base area

Thank you!

cos θ = adjacent / hypotenuse

cos θ = road / stream

cos θ = 20 / 27                 Take the inverse cosine of both sides.

θ = arccos (20 / 27)          Putting this into a calculator gives us....

θ ≈ 42º
