Employers report and pay premiums each quarter based on hours of employee work already performed, and are liable for premiums found later to be due. Industrial insurance accounts have no policy periods, cancellation dates, limitations of coverage or waiver of subrogation (See RCW 51.12.050 and 51.16.190 ).
The Rhombus. A rhombus is a four-sided shape where all sides have equal length. Also opposite sides are parallel and opposite angles are equal. Another interesting thing is that the diagonals (dashed lines in second figure) meet in the middle at a right angle.
They all agree that a rhombus is an equilateral parallelogram, but one says the angles are oblique, one says the angles are USUALLY oblique (implying that they don't have to be), and one specifically says the angles are NOT right angles. So, what's the official word?
