There are 5280 feet in each mile.

There are 60 seconds in each minute and 60 minutes in each hour so there are 3600 seconds in each hour.

(60 miles / hour) x (5280 feet / 1 mile) x (1 hour / 3600 seconds) 

=  (60 x 5280 feet) / (3600 seconds)  =  88 feet / second 

The point where the two graphs cross is the solution.

If the graphs cross at the point (6, -5), then the solution is:  x = 6 and y = -5.

If the lines are parallel, they don't cross and there is no solution.

If, when graphed, one line sits exactly on top of the other, then there is no single solution; every point is a solution to both equations.

1.57=x/((1.28-x)^2)    rearrange by multiplying both sides by the denominator on the right side

1.57(1.28 - x)^2  = x   expand

1.57(1.6384 - 2.56x + x^2) = x   simplify

2.572288 - 4.0192x + 1.57x^2 = x     subtract x from both sides

1.57x^2 - 5.0192x + 2.572288 = 0

This is probably best solved by using the onsite solver

$${\mathtt{1.57}}{\mathtt{\,\times\,}}{{\mathtt{x}}}^{{\mathtt{2}}}{\mathtt{\,-\,}}{\mathtt{5.019\: \!2}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2.572\: \!288}} = {\mathtt{0}} \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = {\mathtt{\,-\,}}{\frac{\left({\mathtt{50}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{5\,649}}}}{\mathtt{\,-\,}}{\mathtt{6\,274}}\right)}{{\mathtt{3\,925}}}}\\
{\mathtt{x}} = {\frac{\left({\mathtt{50}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{5\,649}}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{6\,274}}\right)}{{\mathtt{3\,925}}}}\\
\end{array} \right\} \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = {\mathtt{0.641\: \!021\: \!277\: \!752\: \!175\: \!7}}\\
{\mathtt{x}} = {\mathtt{2.555\: \!921\: \!397\: \!407\: \!06}}\\
\end{array} \right\}$$

Here are two sites that I like....

Let D be the total distance

Then

(2/3) D  = 6     multiply both sides be (3/2)

D = 9

Whats K = ?

Perimeter is 2(a + b) where a and b are lengths of adjacent sides. 

63 (YouJustGotNinjaded

7:00 - 4:45 = 2:15

assuming you're referring to time. 

Here's how I'd do it:

When the question is in this form:     X:00  -  Y:Z

1. Subtract Y + 1 from X, i.e:    X - (Y + 1)      This will be your hours

2. Then add 60 - Z       This will be you minutes

A = pi * r²

pi ≈ 3.14

r is the radius

TO find area it is $${\mathtt{base}}{\mathtt{\,\times\,}}{\mathtt{Heigh}}$$ and to find the perimeter it is$${\mathtt{Base}}{\mathtt{\,\times\,}}{\mathtt{Side}}$$

Hope i was helpful

Do you want:

Area ?

Perimeter ?

Sum of internal angles ?

...

Area of ...

... triangle: bh/2      (base * height/2)

... rectangle: lw       (length * width)

... parallelogram: bh

... any quadrilateral: (pq sin t)/2 (p and q are the length of the diogonals, t is the angle between them)

probability is the ammount or chances you will have

if i have a dice what is the probability of getting a 6? 1/6 because 6 numbers.. and 1 six.. so 1/6 is your answer.. hope i could help :)

I rlly need to know peoplleee thanks <3

Love u all

smoochies'

Well, I would say that your math teacher is boring because she wants you guys to learn.  Maybe if all the time she is SUPER boring than you should tell her somehow in someway...

My math teacher is amazing <3

But just tell her.. and if u get in trouble just say you can say whatever you feel like whenever you want.. Its just your opinion.. and mostly other students also feel that way..

Hope I could help :)

The answer is 275.

Plz use any calc or google "2.75*100" the next time :/

What is 6cm, 7cm and 2cm?

Plz give us enough info and ask again. 

Using the distribuitive property: we get 1/8x-2=7/8

Add two to both sides: 1/8x=23/8

23/8 divided by 1/8=184/8=23

x=23

Not in most calculators. If you find a calculator with ^, it is probably rare to find.

It's just your point of view that makes hime/her so boring. Try to think of math in a fun way and maybe it won't be so "boring."

Just type in 60 mph to feet per second into google and it should give you the answer.

shes not she just seemes that way because shes trying to teach you , you just have to get on her good side by doing your homework and class work.

Ugh...I feel so stupid forgetting to type the negative...

Just do 10/12, and multiply the decimal by 100 to get the answer.

V = pi * r²h

pi ≈ 3.14, r is the radius, h is the heigth
