I don't know what's causing that, rosala.....I actually find Firefox to be pretty good....it's my browser of choice.......I never seem to have many "crashes" with it, and the images always seem to load....there are also numerous add-ons and extensions available with Firefox.....I particulalry like one - Ad Block Edge....it blocks all ads from appearing (even on Youtube)....you might stick with it a while.....maybe you will learn to like it ( )

oh okay!i was thinking its a joke!thanks for the  confirmation!

It's a joke, rosala......[it's a pun on the imaginary number "i" ]

what does this mean CPhill!or is this just a joking answer ?

are u not going to unwrap the lunchbox reinout!and just going to give us riddles?

There are an infinite number of such equations!  Do you have a list that you need to choose from?  If so, you need to say what ones are in the list.

The question is too vague.  Can you give a specific example of what you want to do?

Add the two angles together and divide by 2.

Multiply both sides by 7

x = 7*0.375

The following should help:

The rate of change of z with respect to x is just 2.73, which is positive, so the slope in the positive x-direction is up, and in the negative x-direction is down.

The rate of change of z with respect to y is -1.51 which is negative, so the slope in the positive y-direction is down and in the negative y-direction is up

Go with heureka's answer - I've changed my mind on this twice already!!

Room 1     9 feet by 14 feet  =  126
Room 2   12 feet by 15 feet  =  180
Room 3   15 feet by 15 feet  =  225

Total = 531 sq ft.

[EYE]²

Or, you could subtract.

8-5=3

no sorry we dont have such buttons!

awesome logic CPhill!

20 oz / 36 =   5/9 oz per cookie

2(x-4)> 4x+6

2x - 8 > 4x + 6    subtract 2x from both sides and subtract 6 form both sides

-14 > 2x               dividee both sides by 2

-7 > x     or     x < -7

How to solve for an unknown power e.g 4^x=1024

I.

$$\begin{array}{rcl}
4^x &=& 1024 \\
(2*2)^x &=& 2^{10} \\
(2^2)^x &=& 2^{10} \\
2^{2x} &=& 2^{10} \\
2x&=&10\\
x &=& 5
\end{array}$$

II.

$$\begin{array}{rcl}
4^x &=& 1024 \\
4^x &=& 4^{5} \\
x &=& 5
\end{array}$$

III.

$$\begin{array}{rcl}
4^x &=& 1024 \quad | \quad \ln{()} \\
\ln{(4^x)} &=& \ln{(1024)} \\
x\ln{(4)} &=& \ln{(1024)} \\ \\
x &=& \frac{ \ln{(1024)} } { \ln{(4)} } \\ \\
x &=& 5
\end{array}$$

60 sec in a min.

60 min in a hr.

60 * 60 = 3600 sec in a hr.

24 hr in a day

3600 * 24 = 86400 sec in a day.

approximately 365.24218967 days in a year

86400 * 365.24218967 = 31556925.1875 sec in a year = $31,556,925.1875 in a year.

3.3 trillion dollars = $3,300,000,000,000

$3,300,000,000,000/$31,556,925.1875 per year = 104,572.925923 years

Therefore, it would take you just under 104573 years to earn 3.3 trillion dollars at a rate of a dollar a second.

-Serge

The number of seconds in a year is 3600 x 24 x 365  =31,536,000

So

(3.3 x 10¹²) / (31,536,000) = about 104,642 years

Well, this site does have a really good calculator:) http://web2.0calc.com/

Enter: -4/5 + 3/20

$${\mathtt{\,-\,}}{\frac{{\mathtt{4}}}{{\mathtt{5}}}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{3}}}{{\mathtt{20}}}} = {\mathtt{\,-\,}}{\frac{{\mathtt{13}}}{{\mathtt{20}}}} = -{\mathtt{0.65}}$$

And if you prefer to do the problem by hand:

Convert (-4/5) into a fraction over 20 by multiplying it by (4/4)

= -16/20

Then add 3/20 to -16/20:

= -13/20

Yes. Thank you kitty<3. I tried to get to that point, but I didn't know how to explain it.

Well...10% of 1800m = 180m

So 20% is twice a much = 360m

So, the new route is 360m shorter  !!!
