Answer:
5. C - 180ft²
6. D - 120m³
Step-by-step explanation:
5.
(6.5 x 11) = 71.5
(6 x 2.5) = 15
(6 x 11) = 66
(2.5 x 11) = 27.5
6.
((7.5 x 4)/2)(8) = 120
3 16
Explanation
Factor the numerator and denominator and cancel the common factors.

Answer:
52feet
Step-by-step explanation:
The set up will be a right angle
Let the angle of depression be 30°
The height above the sea level will be the opposite
The distance of the ship from the base is x (adjacent)
Using TOA
Tan theta = opposite/adjacent
Tan 30 = 30/x
x = 30/tan 30
x = 30/0.5774
x = 51.96
x ≈ 52 feet to the nearest foot
Answer:
210
Step-by-step explanation:
