insert your numbers  4  and 25  !

Any 5-digit multiply of 12 must be at least 10000.

Because 12 is 4 x 3, any multiply of 12 must be divisible by both 3 and 4.

To be a multiply of 3, the sum of the digits must be divisible by 3.

Since the only digits are either 1 or 0, the number must contain three 1s.

To be divisible by 4, the number must be even, so it must end with a zero; and, since its "twice-even", it must end with two 0s.

11100 fills the requirements...

1! = 1     2! = 2     3! = 6     4! = 24     5! = 120     6! = 720     7! = too many digits

Adding  1!  to  2!  to  5!  results in 125.

As in what is the percentage of people who like red as their favorite color if 4 people out of 25 people vote for red?

divide 4 / 25

4/25 = 0.16

multiply decimal by 100% to get in terms of percentage

.16 * 100 % = 16%.

16% of people vote for red as their favorite color

Being divisible by 1 doesn't help, because all whole numbers are divisible by 1.

Being divisible by 2 means that the number  n+ 2  is even, so n must also be even.

Being divisible by 3 means that, if the number  n + 3  is divisble by 3, so  n  must also be divisible by 3.

Being divisble by 4 means that, if the number  n + 4  is divisble by 4, so  n  must also be divisible by 4 (and this number must be even).

Being divisble by 5 means that, if the number  n + 5  is divisible by 5, so  n  must also be divisible by 5.

The smallest number divisible by 3, 4, and 5 is  3x4x5  =  60.

The only two distinct digits that, when multiplied, have a product that ends in 1 is 3 and 7.

So, it will be either 23 x 37 or 27 x 73.

One of these is correct, the other isn't.

! is a common notation to mean "Factorial".

The factorial of x is equivalent to [x] * [x-1] * [x-2] * [x-3] ... [x-n]

where [x-n] = 1

So say I want the factorial of 10.

This is 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1

And if I wanted 73!:

73! = 73 * 72 * 71 * 70 * 69 * 68 ... * 3 * 2 * 1

lnx=1-x^3    we can write this as

e^(1 - x³)   = x

e/e^(x³)  = x

e^1  = xe^(x³)    .......notice that this is true when x = 1

U = 0 The initial speed

V = 24 The final speed

a = 9.807 The acceleration

Using these we have 2 main methods of finding the distance it's fallen (and hence the height of the cliff).

First we can use a "Suvat" equation (Named such for using the 5 values: U, V, a, s and t). I won't get into quite why this equation works.

V² = U² + 2as

Re-arranging it gives:

s = (V² - U²) / 2a

Put in the numbers we got...

s = (24² - 0²) / (2 * 9.807)

s = 576 / 19.614

s = 29.3667788314469257

s = 29.37_metres (to 2 d.p.)

Alternatively, find "time" needed to fall and use that.

Since all objects accelerate at 9.8_ms^-2 regardless of mass, we know that this drop took 24/9.807 = 2.4472_seconds (to 4 d.p.).

We can then put it through this other "suvat" equation:

s = [(U + V) / 2] * t

s = [(0 + 24) / 2] * 2.4472

s = 29.37_metres (to 2 d.p.)

To quickly explain:

On average, it's fallen at (24 + 0)/2 = 12_ms^-1

So the distance fell was 12 * 2.4472 = 29.37_metres (to 2 d.p.)

No,you are only retarded

Yes, it should be. I made an arithmetic error.

1 Kilogram = 2.20462262 Pounds

So   45 x 2.20462262  = about  99.2 lbs.

5 / 53   ≈ .094 ≈  9.4%

"20% off" means "80% of"   .....and "of" means  "multiply"  ....so we have

80%  of   319   = 

.80 x 319   =  255.2

You justr type in the precent as a decimal

359.9 or 359

It cann't be determined

thx 

x^4-5x^2+4

$$x^4-5x^2+4
=(x^2-1)\cdot (x^2 -4 )
=(x-1)\cdot (x+1) \cdot (x-2 ) \cdot (x+2)$$

What's 0 divided by 0 equal?

$$\\
\left
\begin{array}{c}

\cdots 3^0 \rightarrow 2^0 \rightarrow 1^0 \rightarrow 0^0 = 1\\\\
\end{array}
\right\} \qquad 0^0 \mathrm{ ~is~indeterminate}$$

5 - 1 third = 4 and 2 thirds

sorry i am greek i didn't mean simplify i meant to do this like this (dont know how its called in english)

p.e.  2x-2= 2(x-1)

5- two thirds= 4 and 1 third
