Lucy’s parents built a swimming pool in the backyard. Use 3.14 for π.
Neporo4naja [7]

Answer:

Distance around the pool = 162.8 feet

Area of the pool = 957 square feet

Step-by-step explanation:

Distance around the swimming pool = Perimeter of the pool

Perimeter of the pool which is a composite figure will be,

= Circumference of the semicircle + Sum of three sides of the pool

= πr + 2×(length of the pool) + width of the pool

= 3.14×(10) + 2×40 + 20

= 62.8 + 80 + 20

= 162.8 ft

Area of the pool = Area of the semicircle + Area of the rectangular pool

                           = \frac{1}{2}(\pi)(r)^{2}+(\text{length}\times \text{Width})

                           = \frac{1}{2}(3.14)(10)^2+(40\times 20)

                           = 157 + 800

                           = 957 square feet

V = rw

where; v = velocity , r = radius , w = angular speed

you're given the diameter = 0.5 miles so the radius = 0.25 miles

180 = (0.25)w
180/0.25 = w
720 radians per hour = w

2pi radians in 1 revolution

720 rad/hr * 1 rev / 2pi rad = 720/2pi rev/hr
= 114.6 rev/hr

Answer:

c = -13.78.

Step-by-step explanation:

21.2x + c  ≡ 5.3(4x - 2.6)

21.2x + c  ≡ 21.2x - 13.78

Equating constant terms:

c = -13.78.
