Answer:
76%
Step-by-step explanation:
First, we know that 6 tables of 6 are already seated. We can go ahead and multiply 6 by 6, which is 36.
This means that 36 of the 150 seats are already taken.
But, we want to find the amount of seats that are still empty. So, we subtract 36 from 150 to get 114 seats.
The question is asking for the percentage, so we can divide 114 by 150 seats to get 0.76. Then, we have to move the decimal to the right 2 spaces to get 76%

Answer:
about 102 feet
Step-by-step explanation:
From the definition of the cotangent function, we can write ...
h·cot(α1) = d1
h·cot(α2) = d2
Where h is the building height and (α1, d1), (α2, d2) are (elevation angle, distance from the building) for the two cases.
We have d2 - d1 = 10 ft, so ...
h(cot(68°) -cot(73°)) = 10 ft
h = (10 ft)/(cot(68°) -cot(73°)) ≈ (10 ft)/(0.404026 -0.305731) ≈ 101.73 ft
The building is about 102 feet tall.
