1. BXADC ( cuz BXC>DXC) Im not sure how to explain it because it just popped out in my head
<span>The answer is -100k + 3 + 101k = -245 - 181k. In the equation –k + 0.03 + 1.01k = –2.45 – 1.81k, numbers have two decimals. So, if we multiply both of sides by 100, we will get whole numbers: 100(–k + 0.03 + 1.01k) = 100(–2.45 – 1.81k). 100 * (-k) + 100 * 0.03 + 100 * 1.01k = 100 * (-2.45) + 100 * (-1.81k). -100k + 3 + 101k = -245 - 181k.</span>
The percentage of this plane that's enclosed by the pentagons is closest to: D. 56.
<h3>How to determine the percentage?</h3>
Since the side of the small square is a, then the area of the tile is
given by:
Area of tiles = 9a²
<u>Note:</u> With an area of 9a², 4a² is covered by squares while 5a² by pentagons.
This ultimately implies that, 5/9 of the tiles are covered by pentagons and this can be expressed as a percentage as follows:
Percent = 5/9 × 100
Percent = 0.555 × 100
Percent = 55.5 ≈ 56%.
