Scientific notation has one digit before the decimal point and multiplies the number by exponents of 10.
So 508 would be written as 5.08
But 5.08 doesn't equal 508, so multiply 5.08 by 100.
100 is the same as 10^2

So the final answer would be:
5.08 * 10^2

Well, you can use a calculator...

But if you mean how to divide w/out a calculator, then
divide in the same way as a regular number; just put the decimal point in the correct place.

For example,
0.246/2
would be
0/2 =0
*decimal point*
2/2 =1
4/2 =2
6/2 =3
So it would be 0.123

1000 20% what is the tax
If you mean the tax is the 20%, then just multiply $1000 by 20%
20% is the same as 0.2
so find 1000*0.2

3(2x+1)-2(x-4)
first, multiply it out.
=(6x+3) - (2x-8)
then distribute the negative sign.
=6x+3-2x +8
then simplify.

=4x+11

That really depends on how many places you're rounding it to.

For example, 567272.32484893 rounded to six digits(or the nearest whole number) would be 567,272
because the 3 in the tenths place rounds down to a 0.
The general rule is that numbers less than 5 round down, and numbers greater than 5 round up.

The sum of the angles in any triangle is 180 degrees.
angle B could be x
then angle A would be (x+30)
and angle C would be (x+60)

So the equation would be:
x + (x+30) + (x+60)=180
start by subtracting 30 and 60 from both sides
so 3x=90

now, just divide to get x, which is the measure of angle B.
After you get B, add 30 degrees for the measure of angle A, and 60 for the measure of angle C.
They should add up to 180 degrees.

0.41 un terminating is the same as 41/100 because of its two decimal places to the right of the decimal point.
It cannot be simplified further, so the simplest fraction answer would be 41/100.

on this site's calculator, you can type it either as sqrt(the number) or click the square root button (to the right of the csc button)
Hope this helps:)
