Answer: 37 sowwy if im wrong
Step-by-step explanation: They are congruent with each other which is the same. When they are on opposite places like that's its always the same degree.
B? Im not sure please correct me
Don’t you have to flip the sign when you divide by a negative? So I think she’s wrong bc the answer should be d is less than or equal to 7.5
Answer:
x ≥ −4
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
4x + 32 ≥ 16
Step 2: Subtract 32 from both sides.
4x + 32 − 32 ≥ 16 − 32
4x ≥ −16
Step 3: Divide both sides by 4.
4x/4 ≥ -16/4
so x ≥ −4 is your answer
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%.
