Answer:
Mr. Drew needs 167.3 ft of wood
Step-by-step explanation:
we know that
The area of a square is

where
b is the length side of the square
we have

substitute in the formula and solve for b

square root both sides

To determine the total length of wood , calculate the perimeter of the sandbox
The perimeter of the sandbox is equal to the perimeter of 5 squares
so

substitute the value of b

therefore
Mr. Drew needs 167.3 ft of wood
Answer:
52
Step-by-step explanation:
S(blue) = S(Whole) - S(cut part)
S(blue) = 7*11 - 5*5 = 77 - 25 = 52
Answer:
1.15
Step-by-step explanation:
tan θ=−4/7, and 270°<θ<360°
θ is in 4th quadrant
sec θ = 8.06 / 7 = 1.15
Answer:
(a) 4 miles
(b) 8.9 miles
Step-by-step explanation:
(a) Theorem 1: In a right triangle, the altitude drawn from the right angle to the hypotenuse divides the hypotenuse into two segments. The length of the altitude is the geometric mean of these two segments.
Hence, the distance d between the park and the library is

(b) Theorem 2: In a right triangle, the altitude drawn from the right angle to the hypotenuse divides the hypotenuse into two segments. The length of each leg of the right triangle is the geometric mean of the lengths of the hypotenuse and the segment of the hypotenuse that is adjacent to the leg.
Thus, the distance D between the park and the football field is
