I didn't notice yours either Jilly, sorry 

That is excellent anon 1 - we would love you to gat an account here and become kwown to us.

I  think I will put you answer in my next wrap   

Thanks anon 2 as well.    

This refers to integer values of the sides in a right triangle where the sum of the squares of the lengths of the two smaller sides is equal to the square of the largest side.

Some well known ones are....

3, 4 ,5

5, 12, 13 , etc.

Also, oddly enough, any multiples of a Pythagorean Triple also generates more Triples.

So, using 3,4,5.....

6,8,10  ......9, 12, 15.....12, 16, 20  are all Triples since they are all multiples of 3,4,5 !!!!

Cute pic Chris :)

The question usually specifies.

Degrees are used for angles in nature  - like bearings, angles of elevation and angles or depression.

When you learn calculus then you have to use radians because degrees won't work.

That is a very rough distinction 

Gee thanks.  Did you already know the answer?    

I = Prt    ....so, to find"r," just divide both sides by Pt.....and we have

I/(Pt)  = r

Yes your explaination is right :)

On some calcs like this one it is called [2nd]

Saseflower is correct.......

And, to add to what she has said, a man named Cantor showed that, between any two values on the number line, an infinite (and uncountable) number of values exist.......

17/27*100 percent

500 in the first hour

500 in the 2nd hour

500 in the 3rd hour

500 in the 4th hour

250 in the last HALF hour

total  2250 miles

OR JUSt

500*4.5=2250 miles

You need to use de distance formula. 

Distance Formula: Given the two points (x₁, y₁) and (x₂, y₂), the distance between these points is given by the formula:  d=√(x2-x1)²+(y2-y1)²

so it would be √(-1-(-3))²+(2-1)²

d=√(-1+3)²+(1)²

d=√(2)²+1

d=√4+1

d=√5   that is the exact answer because 5 is not a perfect sqaure. you would get 2.2360679775

You start off with 100% of the total

If it is Decreased by 5%  it goes Down by 5%  so you end up with  (100-5)% = 95%

You can either find 5% and take it off the original amount OR you can just find 95% to start with

If it is Increased by 5%  it goes up by 5%  so you end up with  (100+5)% = 105%

You can either find 5% and add it to the original amount OR you can just find 105% to start with.

So just remember D is for Decrease and for Down

The percent increase is given by

(New Value - Old Value)/ Old Value

The pecent decrease is given by

(Old Value - New Value)/Old Value

For instance, if something increased from 8 to 10, the  percent increase is just

(10 - 8)/ 8 = 2/8 = 1/4 = 25%

But, if something went from 10 to 8, the percent decrease is just

(10 - 8) / 10 = 2/10 = 20%

Sin(5pi/6) is just a 30 degree angle in the second quadrant.....and the sine of 30 degrees is 1/2

Yea He is weird and is known for being a troll

Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, they write 5.6 x 10^-9

2(k - 7) - 3(5k - 1)

Use distributive property

2k - 14 - 15k + 3

Combine like terms (variables first usually)

-13k - 14 + 3

Combine like terms again (now constants)

-13k - 11

And there's your answer

3 is between 2 and 4. If you imagine a number line, from 0 to 10, it goes 1, 2, 3, then 4 and so on

First, think.

What numbers go into 18 and 21 (ignore the negative for now)?

Well, for 21 only 3 and 7 do.   

Now what numbers go into 18? 2, 3, 6, and 9

What do they have in common?

They both can be divided by 3

Now simplify!

-18/21

Simplify by 3

-6/7

And there's your answer

so (7-9) ^ 4 = 16

well that's the same as (-2)^4

and that's the same as -2 * -2 * -2 * -2

which is ----16

according to rules, a double negative cancells out, so you are left with 16

I believe that's not as simple as your original statement

but

(64pi - 82.8)/3 works too
