Answer:
72 feet
Step-by-step explanation:
- The deck has 6 Sides
- Each side of the deck is 12 feet long
This is an example of a regular hexagon. A hexagon is a polygon that has 6 sides. It is regular because all the sides are equal.
Perimeter of a Regular Hexagon=6l
Length of one side, l=12 feet
Therefore:
Perimeter of the deck = 6 X 12 =72 feet
Answer: 64.3

Answer:
C
Step-by-step explanation:
Let us first write an equation. Using the SOHCAHTOA rule, we should know that the tangent of an angle equals it's . The opposite of our given 20° angle is 9, and the adjacent side is <em>x</em>.

Answer:
I assume you meant 4x^2
So the answer in simplified form is -4x^2-11x+3
Nearly 81 moons will be required to equate the mass of moon to the mass of earth.
Step-by-step explanation:
Mass of earth is 5.972*10^24 kg.
Mass of the moon is 7.36*10^25 g = 7.36*10^22 kg
As mass of the Earth is given as 5.972 * 10^24 kg and mass of the moon is given as 7.36 * 10^22 kg, then the number of moons required to make it equal to the mass of earth can be calculated by taking the ratio of mass of earth to moon.
Mass of Earth = Number of moons * Mass of Moon
Number of Moons = Mass of Earth/Mass of moon
Number of moons = 5.972 * 10^24/7.36*10^22= 81 moons.
So nearly 81 moons will be required to equate the mass of moon to the mass of earth.
