This is the Pythagorean Theorm-
A^2+B^2=C^2
So with this problem, it would be:
6.8^2+x=8.1^2
I hope this helped :)
Quintet is what a stanza containing five lines is called.
13, 6+7=13 thats my answer :D
Just dividing the volumes of the pan, 189 and one bar, 3, suggests that at most she'll be able to cut 63 bars.
But you'll also have to prove that you can divide it in a regular pattern. And you can:
9 divides by 1
10.5 divides by 1.5
2 divides by 2.
So no incomplete bars!
