You plant a tree that is 36 inches tall. After one year, the tree is 43 inches tall. Which expression describes the percent of i
Inessa05 [86]




36 - 100%43 - x  %
we multiply by cross ->  36 * x = 100 / 43 
we should remove '100%' from new value, because we find only increase.. no new value in percent.
x + 100 = (43 * 100)/36 
x =  4300/36 - 100x = 119+ 16/36 -100x = 19 +4/9



the answer is

Dude this is Pythragorean Theorem =)).

You may have missed this part of your lesson. It's ok and also not ok at the same time beacause pythagorean theorem is a meme.

Ok I'll explain once =)).

Thousands of years ago, a mathematician named Pythagore found out that if we have 3 squares, with one square's area equals to the sum of two other squares, then when we put the sides of the squares together to form a triangle , it'll always be a right triangle ( a triangle with one of its angle is 90°). A square area is measured by the length of its side multipled by itself. So he came up with the statement : In a right triangle, the length of the hypotenuse( the side that does not connect to the right angle) is equalled to the sum of squared other sides.

EG.

In this triangle, the right angle is ^ACB. If length of BC is <em>a</em><em>,</em><em> </em>length of AB is <em>c</em>, length of BC is <em>a</em>

A

I We have a formula :

I \ <em>a</em>^2 + <em>b</em>^2 = <em>c</em>^2

I \

I \

I <em>b</em> \ <em>c</em>

I \

I \

I______\

C <em> a </em> B

So now you can use pythagorean theorem to show off =)).

HOPE YOU LEARN WITH JOY AND HIGH GRADES !!!
