Answer:
13 Rungs
Step-by-step explanation:
According to the Question,
- Given, The length of the ladder that will run from the ground to the door of the treehouse is 9 feet ( 9 × 12 = 108 inches).
The plan recommends that the rungs of the ladder be spaced at 8-inch intervals.
- And, The first and last rung should be 6 inches from the respective ends.
Thus, the rungs Cover on 108 -(6+6) = 96 inches with 8-inch gaping between each rung.
- Therefore, the Total Rungs on the treehouse ladders have (96/8)+1 ⇒ 13 Ladders.
Multiply the volume by 3. For example, suppose the volume of the sphere is 100 cubic units. Multiplying that amount by 3 equals 300.
Divide this figure by 4π. In this example, dividing 300 by 4π gives a quotient of 23.873.
Calculate the cube root of that number. For this example, the cube root of 23.873 equals 2.879. The radius is 2.879 units.

Answer: 117 degrees
Step-by-step explanation:
90+27=117 degrees
If there is a square between the angle, then it's usually a right angle, and right angles are 90 degrees.
Let Upper Level = x
Middle level = 2x+40
Lower level = 3x-50
The sum of those 3 has to equal 15,002 seats.
X + (2x+40) + 3x-50) = 15, 002
Simplify the left side by combining the like terms:
6x - 10 = 15,002
Add 10 to each side:
6x = 15,012
Divide both sides by 6 to solve for x:
X = 15012 / 6
X = 2502
The upper level is X , so has 2,502 seats.
Middle level = 2x +40 = 2(2502) +b40 = 5004 + 40 = 5,044 seats
Lower level = 3x-50 = 3(2502) -50 = 7506 - 50 = 7,456 seats
