##### If r is represented by the decimal 0.t5 what is the digit ?

1) r< 1/3 2) r < 1/10 Original Answer is B, cause its only satisfied for 0.09 - 0.01 -> therefore t=0 I thought, that it is also possible, that r is negative, because its not stated in the question. so possible solution would be -0,95, -0.85...and therefore its NOT sufficient -> E Or is this a defin...

but I don't understand why statement B isn't the right choice. If we assume, that the author did NOT write a accurate report about Prince Sviatov, then the events desribed in the text must not occur in 1165.

I am also confused with this question. In statement a) it is said, that both diagonals are equal. I looked into my mathbook and there is written: if it is a rectangle and both diagonals are equal, they bisect each other. With this knowledge we know two sides of the triangle and can solve with pythar...
