<span>On Friday, a bowling alley made $842.72 from lane rentals and $412.38 from the concession stand. On Saturday, their lane rentals were down by 1/8 but the concessions increased by 1/2 What is the total amount that the bowling alley earned in lane rentals and concessions on Friday and Saturday? A.$1,355.95 B.$1,580.10 C.$1,992.48 D.$2,611.05

lane rentals: 842.72 x (8/8-1/8) = 842.72 x 7/8 = 737.38
concessions: 412.38 x (1 + 1/2) = 412.38 x 1.5 = 618.57

Total: 737.38 + 618.57 = 1,355.95 Choice A.</span>

A person sights a boat from 235 feet above sea-level as shown. If the angle of depression from the man to the boat is 21 , then
Evgen [1.6K]

Answer:

B = 612.2 ft

Step-by-step explanation:

Solution:-

- The elevation of person, H = 235 ft

- The angle of depression, θ = 21°

- We will sketch a right angle triangle with Height (H), and Base (B) : the boat's distance to the edge of the cliff and the angle (θ) between B and the direct line of sight distance.

- We will use trigonometric ratios to determine the distance between boat and the edge of the cliff, using tangent function.

                             tan ( θ ) = H / B

                             B = H / tan ( θ )

                             B = 235 / tan ( 21 )

                             B = 612.2 ft
