With this problem, you have to do order of operations.
you do the multiplying first (the part in parenthesis)
(5 x 1/3) - (3 x 2/3)
5/3 - 6/3 = -1/3
Answer:
448
Step-by-step explanation:
320/5 is 64 miles per hour
64*7 is 448
she will travel 448 miles in 7 hours
The answer is =x^2 +x +1 +2/x-1
Answer: the distance of the boat from the foot of the lighthouse is 290.5 feet.
Step-by-step explanation:
The right angle triangle ABC representing the scenario is shown in the attached photo.
Angle A is alternate to the angle of depression, hence, they are the same.
The height of the lighthouse represents the opposite side of the right angle triangle. The distance, x of the boat from the foot of the lighthouse represents the adjacent side of the right angle triangle.
To determine x, we would apply
the tangent trigonometric ratio.
Tan θ, = opposite side/adjacent side. Therefore,
Tan 11.1 = 57/x
x = 57/Tan 11.1 = 57/0.1962
x = 290.5 feet to the nearest tenth.
