Answer:
B. x ≤ 2.
Step-by-step explanation:
56 - 10x ≥ 20 + 8x
-18x ≥ -36
x ≤ -36/-18 = 2. ( Note that the inequality sign flips because we are dividing by a negative value).
Answer:
(1/2)(4√3ft)(6 ft) = 12√3ft2.
Step-by-step explanation:
For an equilateral triangle, the apothem is 1/3 of the height, so the height is 3 times 2 ft or 6 ft.
The base of the equilateral triangle is the apothem times 2√3 or 2ft times 2√3 = 4√3ft.
So the area of the triangle is (1/2)(base)(height) or
(1/2)(4√3ft)(6 ft) = 12√3ft2.

If rappelled means he fall down, I'd say he's need to climb 40 feet up. Because he rappelled 30 feet down, -30 feet from where he used to be, and then he fell an additional 10 feet down, so -10 from the -30, which is -40. He needs +40 feet to get back up. I'd say the answer's 40 feet climb.
