18 glasses of water
3.6/.2=18
<em>Answer:</em>
<em>7/78 - 35/78i</em>
<em>Step-by-step explanation:</em>
<em>A complex number is a real number, an imaginary number or a number with both real and imaginary number. Its standard form is:
</em>
<em>a + bi
</em>
<em>
</em>
<em>For the expression, 7/ 3-15i
</em>
<em>
</em>
<em>(7/ 3-15i) (3+15i)
</em>
<em>21 - 105i / (234)
</em>
<em>7/78 - 35/78i
</em>
12 * 100 = 1200/96 = 12.5
Answer = 12.5%
You mulitply 12 by a hunndred, since a percent means "out of a hundred." Then, you divide that, by 96, since, you want to find the percent out of 96.
The correct choice is the third one. Y=2/3x
So basically the ladder is creating a right triangle with the ground and the wall. Ladder is the hypotenuse (h), building = b, ground = g
b = h - 22 ft
g = 1010 ft
use Pythagorean Theorem to determine the length of h:
![{c}^{2} = {a}^{2} + {b}^{2} \\ {h}^{2} = {(h - 22)}^{2} + {1010}^{2} \\ {h}^{2} = {h}^{2} - 44h + 484 + 1020100](https://tex.z-dn.net/?f=%20%7Bc%7D%5E%7B2%7D%20%20%3D%20%20%7Ba%7D%5E%7B2%7D%20%20%2B%20%7Bb%7D%5E%7B2%7D%20%20%5C%5C%20%20%7Bh%7D%5E%7B2%7D%20%20%3D%20%20%7B%28h%20-%2022%29%7D%5E%7B2%7D%20%20%2B%20%7B1010%7D%5E%7B2%7D%20%20%5C%5C%20%7Bh%7D%5E%7B2%7D%20%20%3D%20%20%7Bh%7D%5E%7B2%7D%20-%2044h%20%2B%20484%20%2B%201020100)
The h^2 terms cancel out to = 0
