Answer:
7/100 or 0.07
Step-by-step explanation:
There is a total of 100 small cubes in this square. Only 7 small squares are shaded. 7 squares of 100 squares as a fraction is <em>7</em><em>/</em><em>100</em><em> </em>and as a decimal is <em>0.07</em>
For a regular 8 sided polygon each angle against each side, is 360/8=45.
So x=45/2=22.5
Then
![\tan(22.5) = \frac{y}{8} \\ and \: we \: know \: \tan(22.5) = \ \sqrt[]{2} - 1 \\ so \: y = 8( \sqrt[]{2} - 1)](https://tex.z-dn.net/?f=%20%5Ctan%2822.5%29%20%20%3D%20%20%5Cfrac%7By%7D%7B8%7D%20%5C%5C%20and%20%5C%3A%20we%20%5C%3A%20know%20%5C%3A%20%20%5Ctan%2822.5%29%20%20%3D%20%20%5C%20%5Csqrt%5B%5D%7B2%7D%20%20-%201%20%5C%5C%20so%20%5C%3A%20y%20%3D%208%28%20%5Csqrt%5B%5D%7B2%7D%20%20-%201%29)
G1 : 0.3(2000) = 600
G2: 0.2(2000) = 400
G3: 0.15(2000) = 300
Divide 8/5 by 5/6 and you will get 1 and 23/25 is greater than v
So v is less than
1 23/25
