Use indirect measurement for this: 32/20=h/1.2

Cross multiply: 38.4=20h.

Divide by 20: and that's how tall the person is in meters.

10*10 = 100. 

Circumference=2$${\mathtt{\pi}}$$r, r for radius.

Plug in the values.

Circumference = 2 x pi x radius

                    C  =  2 x pi x 3  =  18.85 inches (approximately)

Is this a solid post or a hollow post?

How much mortar are you using between bricks. 

The size of the bricks won't allow for a solid post without mortar for the size of the post.

First:  to calculate the amount after 20 years:  A  =  p[ (1 + r)ⁿ - 1 ] / r

Where  p  =  amount invested each month:  200

            r  =  percentage rate per month:  .05/12

            n  =  number of months  =  20 x 12  =  240

A  =  200[ (1 + .05/12)²⁴⁰ - 1 ] / (.05/12)  =  130,206.73

Second:  to calculate that value after 10 years:  A  =  p(1 + r)ⁿ

Where p and r are the same as above and n = 10 x 12  =  120

A  =  130 206.73(1 + .05/12)¹²⁰  =  214,451.73

Just to help you get started, the problem involves using distance formula to find the length of the segments and then using sin, cos, and tan, to find the angle measures based on the lengths of the sides. You can google distance formula and find a calculator for it online where you just plug in the points on the graph, and rememeber that each triangle has angles that add up to 180°. Good luck on your problem.

cot(x) and tan(x) are multiplicate inverses, so if cot(x) = 2/3, tan(x) = 3/2.

Circumference  =  pi x diameter

Circumference  =  pi x 5  =  15.71 feet  (approximately)

5 ÷ (9/10)  =  5 x (10/9)  =  50/9  =  5 5/9  =  5.5555...

sin^-1(0.4067)  =  asin(0.4067)  =  24°  (approximately)

Or better yet, just multiply the top numbers together (2x3) and the bottom numbers (5x7) to get the top and bottom numbers for the new fraction, which would be 6/35

2x + 3y  =  14     --->   x 3     --->     6x + 9y  =  42

3x -  4y  =  4       --->  x -2     --->    -6x + 8y  =  -8

                                                                    17y  =  34

                                                                        y  =  2

If y = 2:  2x + 3y  =  14     --->     2x + 3(2)  =  14     --->    2x + 6  =  14

                                                                                                        2x  =  8

                                                                                                          x  =  4

Lol, I don't even understand that. However, things can take well over 200 pages, like all of pi.

|7 - 9|  =  |-2|  =  2      (Absolute value)

5·2 - 2  =  10 - 2  =  8

135k^2 or 18225k. Um I think thats right

Human hair:  8.0 x 10^-4  =  0.00080

Cat hair:        4.0 x 10^-1  =  0.40

Subtracting:   0.40  -  0.00080  =  0.3992

Using rules of precision, the answer becomes 0.40

Since there is only an X, we cannot help you, were you trying to type a link?

2/5 + 2/x  =  1

Multiply both sides by 5x:

2(5x)/5 + 2(5x)/x  =  1(5x)

10x/5 + 10x/x  =  5x

2x + 10  =  5x

         10  =  3x

x = 3 1/3

The odd numbers are:  1, 3, 5, 7, ...  so the third odd number is 5

The squared numbers are 1² = 1, 2² = 4, 3² = 9, ... so the third squared number is 9

The cubed numbers are 1³ = 1, 2³ = 8, 3³ = 27, ... so the third cubed number is 27

Sorry i'm not a troll, i didn't know that it does stuff with links

What's the problem?

6x² - x - 1  =  (3x - 1)(2x + 1)
