The central angle of a hexagon is :
Ф = 360° : 6 = 60°
The hexagon will map onto itself 6 times.
It will turn through angles : 60°, 120°, 180°, 240°, 300° and 360°.
Whatever% of anything is just (whatever/100) * anything.
so 56% of 75 mates like it, how much is 56% of 75? well is just (56/100) * 75, namely 42.
and 80% of 60 relatives like it as well, how much is 80% of 60? well, is just (80/100) * 60, namely 48.
how many more? well, 48 - 42.
<span>Given that a farmer has 13 cows if a bolt of lightning kills all but 5 of them, this means that the bolt of lightning killed all the cows except 5.
Therefore, the number of cows that survived is 5 cows.

4(k-2) when it says 2 less than it means you are subtracting from the constant and 4 times means you are multiplying the whole equation with 4.
