more sepcifically two different radicals i had meant

Mind the units.  Answer is in seconds (not m/s).

1 Km / (850 m/s) = 1000m / (850 m/s) = 1 3/17 seconds

your answer is 515

Its 515

1/2 kilograms divided among 4 people

= 1/2 ÷ 4     kilograms per person

= 1/8           kilograms per person     :)

Thanks, hectictar.....here's another method.....

y=34x^2−6x+15

In the form   y  = Ax^2 + Bx + C  the x coordinate of the vertex  is given by :

-B  / [ 2A ]   =    - (-6)  / [ 2 * 34 ]   =   6/ 68   =   3/34

Subbing this back into the function, the y coordinate of the vertex is :

34 (3/34)^2  - 6 ( 3/34)  + 15   =

9 / 34   -  18/34   +  15  =

-9/34  + 510/34  =

501 / 34

You can type a caret into the box like this: " ^ "

Also you can press the x^y button.

So if you wanted to do 10² type: " 10^2 "

If you want to do 10³⁺⁴      type: " 10^(3+4) "

The shape is a quadrilateral with at least one set of parallel sides, or a triangle. Technically, a tirangle is a trapezoid with the shortest base having a length of 0.

Additionally, not enough information is given to solve, and the equation for area is:

$area = \frac{b1 + b2}{2} * h$

We want to get the equation into vertex form.

y = 34x² - 6x + 15            Subtract 15 from both sides.

y - 15 = 34x² - 6x             Divide through by 34.

(y - 15)/34 = x² - 3x/17     Add ( [3/17]/2 )² , or 9/1156 , to both sides.

(y - 15)/34 + 9/1156 = x² - 3x/17 + 9/1156       Factor the right side.

(y - 15)/34 + 9/1156 = (x - 3/34)²                     Multiply through by 34.

y - 15 + 9/34 = 34(x - 3/34)²

y - 501/34 = 34(x - 3/34)²

So...when the equation is written in this form, we can see that the vertex is located at (3/34 , 501/34)

Just add the equations and we get :

6y =  6      divide both sides by 6

y  = 1

Subbing this back into either equation to find x

1x  + 2(1)  =  5

x +  2   =  5       subtract 2 from both sides

x  =  3

So   the solution set  is  { x, y }    =    { 3, 1 }

Do you have some answers to choose from ???

4% as a decimal = 4/100 = 0.04

Multiply 5000 by 0.04, that is your answer.

The above simplified is: 4y - x = 1

                                      2y + x = 5

These 2 equations are in standard form. Let's use a method to solve it without changing them at all.

Add the 2 equations together, keeping the variables on the same side:

 Divide each side by 2, y = -2

Put the solution for y (-2) back into each equation. Then, solve for x.

If you had needed or wanted to, you could have multiplied the bottom equation by -2 to eliminate y, then solve for x. You can multiply both equations by numbers, as long as you remember to multiply both sides by that number.

pH = negative log₁₀ of the hydronium ion concentration in a solution

concentration of hydroxide = concentration of hydronium @ pH = 7

Multiply 7 by 2 (so when the 2 are added up, it equals 14)

Subtract 11.3 from 14, that is the hydroxide concentration

I trust you can do the above subtraction on your own.

Volume_sphere =    (4/3) * pi *  ( radius ) ^3

of means multiply

18% as a decimal = 0.18

300 * 0.18 = 3 * 18 = 54

Your answer: 54

8y + 2  =  98     subtract 2 from both sides

8y   =  96         divide both sides by 8

y  = 12

In a 30 60 90 triangle the ratio of  the sides should be x: x root 3: 2x respectively so if the side across from the 90 degree angle is 90 then the short side should be 45, and the other side should be 45 root 3.
