And  √189  can be simplified as = √[3^3 * 7] = √[9 * 21] =  3√21

 0.444444......  = 4/9

So

(99/100) * (4/9)  =    (99/9) ( 4/100) =    11/25

V=pi*r^2*h

V=pi*100*100*40  cm^3

$${\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{10\,000}}{\mathtt{\,\times\,}}{\mathtt{40}} = {\mathtt{1\,256\,637.061\: \!435\: \!917\: \!295\: \!385\: \!1}}$$

1 256 637 cm^3

= 1256 637 mL

= 1 257 L     (to the nearest L)

There may be other possibilities, but 1.6 is one.....

1.6  =  8/5

1 / (8/5)   =   5/8   =  .625

BTW....a fraction will result in a non-repeating decimal when its denominator can only be written in terms of 2 and/or 5 .....  (and nothing else).

that would depend on what the units are to start with!

In a sence, whole numbers ARE decimal numbers.  The invisable decimal point is at the back

7 = 7.

it says the prob of spinning no2 = prob of spinning no 2 

Well now that is not very helpful!

also, how many numbers are on the the spinner?

your answer is

(5x+2)/6y *9xy^2

this is

$$\frac{(5x+2)}{6}*y *9xy^2$$

See, the first y will be in the wrong place - it is supposed to be on the bottom! 

OK, I DID!! AND WHAT YOU SAID, BE PATIENT! I WAITED FOR 47 MINUTES!! YOU CALL THAT NOT PATIENT?!?

Thanks Radix and Derrickid

Radix: That is a nice interactive web page you have there.  Did you build it yourself ?    

Derrickid: Your answer is good but do not forgetthe % sign.  

But i have done the division before the times. 

In the fraction then * 9xy^2

No not quite MG because the first y would be on the top. 

The division would  be done BEFORE the multiplication    

Can you be Patient!!

You should be happy you even have access to do this!

Great mathmeticians on here aren't charging you ANYTHING to solve your questions!

They're are doing this out of their own time for you.

And here you are, shouting?

If you're going to do that, then I suggest you study, and answer it from your own knowledge. That way you can only blame yourself.

If not, learn to respect!

ok.

(5x+2)/6y *9xy^2

Data that give you an exercise of the sine law... would always you darandos angles?

I am sorry but this translation does not make sense.

Perhaps check your spelling and try again.

Sorry but I don't know what you mean.   

I have interpreted the question differently from Radix,  that is why we have different answers 

AND that is why brackets are so VERY important!

$$\\cosx\div tanx \times sinx\\\\
=cosx \div \frac{sinx}{cosx}\times sin x\\\\
=cosx \times \frac{cosx}{sinx}\times sin x\\\\
=cos^2x$$

You  can use this formula

for instance, if the car costs $20 000   

The interest is 18% p.a (reducable) and payments are made monthly for 5 years

n = Number of months = 5*12 = 60

i = interest per month = 0.18/12 = 0.015

PV = present value (of the loan) = $20000

I will enter it inot the web2 calc like this

20000=C*((1-1.015^-60)/0.015)

and this is the output

$${\mathtt{20\,000}} = {\mathtt{C}}{\mathtt{\,\times\,}}\left({\frac{\left({\mathtt{1}}{\mathtt{\,-\,}}{{\mathtt{1.015}}}^{-{\mathtt{60}}}\right)}{{\mathtt{0.015}}}}\right) \Rightarrow {\mathtt{c}} = {\frac{{\mathtt{115\,119\,700\,000}}}{{\mathtt{226\,672\,237}}}} \Rightarrow {\mathtt{c}} = {\mathtt{507.868\: \!548\: \!542\: \!184\: \!281\: \!7}}$$

So the payments will be   $507.87 per month for 5 years

to make life easier, ill do it: $$\sqrt189$$ is the answer

6^2 + x^2 = 15^2. now you can solve that by yourself or on the calc

BTW, i look at the explanations

Hi Zac,

I didn't know that could be graphed in GeoGebra !

I use the download version - you seem to be using the online version, I wonder if it makes a difference?

Where did you go to graph the equations? I mean how did you do it?

Oh - Sorry Zac, yes, your answer makes perfect sence :)

OK...oops i did caps, whatever

$$4^{-1.5}=4^{-3/2}=(4^{1/2})^{-3}=(\sqrt4)^{-3}=2^{-3}=\frac{1}{2^{+3}}=\frac{1}{8}$$

1.1875 → 11875/10000 → 19/16
