Answer:
P = 6 2/3 ft
Step-by-step explanation:
The formula for the perimeter of a rectangle of length L and width W is
P = 2(L + W).
Here the perimeter is P = 2(1 2/3 + 5/6) = 2(5/2 + 5/6)
= 2(15/6 + 5/6) = 2(20/6)
= 40/6 = 20/3
P = 6 2/3 ft
The distance between the boat and the ocean's floor is 19m

How to get the distance from the ship to the ocean's floor?</h3>
We can see this as a right triangle, where the rope with the anchor is the hypotenuse. So we already know that the hypotenuse measures 30m.
We also know an angle, it measures 39°, and we want to get the opposite cathetus to said angle (the height).
Then we use the relation:
Sin(a) = (opposite cathetus)/(hypotenuse).
Replacing the values that we know, we get:
Sin(39°) = d/30m
sin(39°)*30m = d = 18.9m ≈ 19m
The distance between the boat and the ocean's floor is 19m.

Answer:
75
Step-by-step explanation:
Average needed to get grade C = 70
Average = Total Amount / No of Items.
No of items = 4
therefore Total needed = 70 x 4 = 280
current total score = 66.75 + 66 + 72.25 = 205
the fourth test minimum score = 280 - 205 = 75
