1/100 because 1 divided by 100 (since a percentage is out of one hundred) 0.01. 0.01 is the same as 1/100

it is very irrational

21!!

$${\mathtt{c}} = {\mathtt{3}}$$

Yes it is indeed!

(150/360)*36

150/10

that is a simple question....

Well Rosala, It just sounds like a lot of hot air to me. :)

The volume of a pyramid can be found by using the formula:  V  =  (1/3)·(Area of the Base)·(Height)

Since the base is square, 280 meters on each side, its area is  280 x 280  or  280².

So:  V  =  (1/3)·(280²)·(130.6)  =  ...

i didnt check it...i will

Umm, this is a calculator site,  how about that for a coincidence.  

I do not think it betrayed.  What answer did it give you?

i didt work it out...oops.....i just...guessed....thought shortcut may help.....but it betrayed!

Oh, I see what you are saying Alan,  but I think it the lengths of the legs of the isosceles triangles are the same then the height in the middle would be the same also.  So you can do it either way i think.  

What are the sides of the isosceles triangles.

1)  $${\sqrt{{{\mathtt{22.9}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{{\mathtt{12.5}}}^{{\mathtt{2}}}}} = {\mathtt{26.089\: \!461\: \!473\: \!936\: \!176\: \!3}}$$

and

2)   $${\sqrt{{{\mathtt{23.7}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{{\mathtt{11}}}^{{\mathtt{2}}}}} = {\mathtt{26.128\: \!337\: \!107\: \!439\: \!501\: \!2}}$$

Again correct to the neares 0.1 of a foot.   Mmm

I think it's the sloping sides that have to be the same length Melody, but even here there is a small discrepancy.

.

(–14.3) ∙ 6.7 ∙ (–5.8) = x ∙ (–5.8) ∙ (–14.3)

Divide both sides by -5.8

Divide both sides by -14.3

and what are you left with ?

its been going good.........im justa  bit worried though,,,,hows yours?

thats a really clever example melody!

$$\int\frac{1}{x}dx=ln(x)+c$$

ln is log to the base e and c is a constant.

.

I think this should be a² + b² = c² rather than a²*b² = c²!

here, a = 5 and b = 12.  c, the hypotenuse, is then 13.  

. 

I think this is the net that Melody had in mind:

A net is a pattern you can fold to make a solid shape.

Hi Everyone,

Our indefatigable  answerers today were Alan, CPhill, Geno3040, Tetration, Saseflower, Rosala, Sasini, Labby, The JonyMyster, Ousmane108, CowgirlIAMS, Dominique9, Mailan3030, Mohamed Sabir and KawaiiKute.  Thanks all, you are wonderful.

As you can all see our number of answerers is increasing all the time and some of these people answer a lot ot questions and they do it well.  There is also a number of very proficient anonymous answerers.  It would be really good if they joined up and then their skills could be properly recognised. (eg I would not need to spend so much time checking their answers)  :/
