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%.

Complete Question:
The plane is tiled by congruent squares of side length a and congruent pentagons of side lengths a and a²/a, as arranged in the diagram below. The percent of the plane that is enclosed by the pentagons is closest to (A) 50 (B) 52 (C) 54 (D) 56 (E) 58
Answer:
2 cups of flour
2/3 cup of sugar
1 1/3 cups of chocolate chips
Step-by-step explanation:
3 dozen chocolate chip cookies
3 cups of flour
1 cup of sugar
2 cups of chocolate chips
The recipe is for 3 dozen cookies as stated above.
If you make 2 dozen cookies, then you are making 2/3 of the recipe since 2 is 2/3 of 3.
That means you need 2/3 of all the ingredients.
2/3 × 3 dozen chocolate chip cookies
2/3 × 3 cups of flour
2/3 × 1 cup of sugar
2/3 × 2 cups of chocolate chips
We simplify the amounts to:
2 dozen chocolate chip cookies
2 cups of flour
2/3 cup of sugar
1 1/3 cups of chocolate chips
2x + 4 = xg
Reorder the terms:
4 + 2x = xg
Ans
4 + 2x = gx
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1gx' to each side of the equation.
4 + -1gx + 2x = gx + -1gx
Combine like terms: gx + -1gx = 0
4 + -1gx + 2x = 0
Add '-4' to each side of the equation.
4 + -1gx + -4 + 2x = 0 + -4
Reorder the terms:
4 + -4 + -1gx + 2x = 0 + -4
Combine like terms: 4 + -4 = 0
0 + -1gx + 2x = 0 + -4
-1gx + 2x = 0 + -4
Combine like terms: 0 + -4 = -4
-1gx + 2x = -4
Reorder the terms:
4 + -1gx + 2x = -4 + 4
Combine like terms: -4 + 4 = 0
4 + -1gx + 2x = 0
The solution to this equation could not be determined.
