Preciseness!! ^^

 

And you are right on track for my next question; which is the fomula..

[mark_pogi]

prove that:

 

11 + 2 = 1

Gee this is not moving.

 

A quick question:

How much dirt is in a hole that is 3 meters deep and 6 inches in diameter?

A quick question:

How much dirt is in a hole that is 3 meters deep and 6 inches in diameter?

 

volume = Area * Height = 3337.78 cubic inches

 

tama ba?

[destron]

volume = Area * Height = 3337.78 cubic inches

 

tama ba?

 

Nope. Try again.

Metric or English will do.

6 in * 2.54 cm/in = 15.24cm

Depth 3m * 100cm/m = 300 cm

 

Volume = 3.1416 x 15.24 cm x 15.24 cm x 300 cm

= 218898.14 cubic cm

 

 

Nope. Try again.

 

Q:How much dirt is in a hole that is 3 meters deep and 6 inches in diameter?

[bene_factor]

I guess the answer is zero, it being a hole?

 

Unless the question was: How much dirt _was_ in the hole?

 

but that's a good one.

How many total squares are there in a regulation chess board?

[bubuy]

Can you write the numbers 0 through 10 using five figure 2s, no more and no less, and the usual signs: +, -, x, /, and parentheses? To start:

 

0 = 2 - 2/2 - 2/2

1 = 2 + 2 + 2 - 2 - 2

2 =

3 =

4 =

You got it!

 

How many total squares are there in a regulation chess board?

 

There are 65 squares on a chess board. 64 little squares and the whole board is a square so 64+1=65

All possible combinations of different sized squares it comes to 204.

All possible combinations of different sized rectangles it comes to 1296.

 

Can you write the numbers 0 through 10 using five figure 2s, no more and no less, and the usual signs: +, -, x, /, and parentheses? To start:

 

0 = 2 - 2/2 -2/2

1 = 2 -2/2 +2 -2

2 = 2 +2 +2 -2 -2

3 = 2 +2/2 +2 -2

4 = 2 +2/2 +2/2

5 = 2 +2 +2 -2/2

6 = 2 +2 +2 +2 -2

7 = 2 +2 +2 +2/2

8 = 2 x2 x2 +2 -2

9 = 2 x2 x2 +2/2

10 = 2 +2 +2 +2 +2

If a=b,

 

multiplying both sides by a,

a²=ab

 

subtracting b² from both sides,

a²-b²=ab-b²

 

factoring both sides,

(a+b )(a-b )=b(a-b )

 

dividing both sides by a-b,

a+b=b

 

but since a=b,

b+b=b

 

2b=b

 

dividing both sides by b,

2=1

 

Q: Where did it went wrong?

[twisted minds]

If a=b,

 

multiplying both sides by a,

a²=ab

 

subtracting b² from both sides,

a²-b²=ab-b²

 

factoring both sides,

(a+b )(a-b )=b(a-b )

 

dividing both sides by a-b,

a+b=b

 

but since a=b,

b+b=b

 

2b=b

 

dividing both sides by b,

2=1

 

Q: Where did it went wrong?

 

if a=b then a-b = 0. so in step 4, you are dividing both sides by 0.

eto para sa inyo

 

sagutin nyo ha

pwedeng magdiscuss

isa ito sa mga problems nabinibigay ko sa mga students ko

 

si A bumaba sa escalator tumakbo nabilang nya 75 steps ang hinakbang nya

si B bumaba sa escalator naglakad nabilang nya 50 steps ang hinakbang nya

ang pagtakbo ni A is twice as fast sa paglakad ni B

 

ilan lahat ang steps ng escalator
