56 / 64   = 

[ 7 * 8 ] / [ 8 * 8] =

[7 / 8] * [8 / 8]  =

7/8  * 1  =

7/8

\(x^{2} + 6x - 9\)

is known as an expression. Expressions are not solvable as there is nothing defining equality. A solvable equation would have an equals sign (=).

Let "y" be the amount of words typed and let "x" be the amount of minutes that pass.

If she types 45 words per minute (45 words/ minute), then that should be multiplied by "x" (seconds) in order to cancel out minutes and get words which would be on the other side of the equal side or "y".

Your equation would turn out to be :

y = 45x

The surface area of a sphere is equivilent to A = 4πr^2.

All you need to do is plug in (π/9) for A and solve for r.

(π/9) = 4πr^2

Divide 4 on both sides:

(π/36) = πr^2

Divide π on both sies:

(1/36) = r^2

Take the square root of both sides:

1/6 = r

Use appropiate units and get...

Radius = 1/6 feet

GameMaster.....this is similar to the one I answered yesterday

The inequality equation is

5.50P + 50 ≤ 100      where P is the number of people she can invite ...  subtract 50 from both sides

5.50P ≤  50           divide both sides by 5.50

P ≤ about 9.09  people........so.......call it 9 people

Here's the graph :  [substituting x for P] : https://www.desmos.com/calculator/muphnhy17g

I'm sure you meant πr^2. The only thing that comes to mind is, that is the equation to find the area of a circle.

A profit is a financial gain, especially the difference between the amount earned and the amount spent in buying.

So you'd see this as +$460 since he is GAINING money. Not losing it.

A = πr² is the equation to a whole circle.

A = (1/2) πr² is the euqaton to a SEMIcircle (or half of a circle)

Since you are given a diameter of 50.6 cm, you need to half it to get the radius... that would be 25.3 cm.

Now all that's left to do is plug in and solve:

A = (1/2) π(25.3 cm)²

The exact answer is...

A= 320.045π cm²

Area = (1/2) pi * (radius)^2            radius = diameter/2  = 50.6/2  =   25.3 cm

So

Area =

(1/2) pi * (25.3)^2  = about   1005.45 cm^2

Wait, can someone clarify what this is exactly? There are many things on this site that are new to me, and this is one of them.

5.3^2.5  = 64.668036

5.3^2.5  =  about 64.668

It's about 4.1428571428571429. 

A way to figure that out is to divide 29 by 7 using the calculator. You can convert fractions into decimals that way. :)

x^2 - 12x + 36     this is a perfect square trinomial.....it factors as

(x - 6) (x - 6)   =

(x - 6)^2

Volume is lwh, so multiply all of them. 

25x60x7=10500. 

The volume of the pool is 10,500 cubic feet.

4 or if you are an idot 13. correct answer is 4

put the 2 0's behind one of the 100. the answer is 10000 or 10,000

if the number is 12 than you hit the minus key, or button on the calculator. -12

For example, if F(x) = 0 then

x^3 - 2x^2 + x - a = 0

This can be written as

(x - 2)(x^2 + a/2) = 0

In order for this to match the first equation the coefficient of the x term must be 1.  That is, a/2 = 1.

i.e.  a = 2
