On a certain hot summer day, 673 people used the public swimming pool. The daily prices are 1.75 for children and 2.00 for adult
amid [387]

Answer:

Number of children = 386

Number of adults = 287

Step-by-step explanation:

Let

x = number of children

y = number of adults

x + y = 673 (1)

1.75x + 2y = 1249.50 (2)

From (1)

x = 673 - y

Substitute x = 673 - y into (2)

1.75x + 2y = 1249.50

1.75(673 - y) + 2y = 1249.50

1177.75 - 1.75y + 2y = 1249.50

- 1.75y + 2y = 1249.50 - 1177.75

0.25y = 71.75

y = 71.75/0.25

y = 287

Substitute y = 287 into (1)

x + y = 673

x + 287 = 673

x = 673 - 287

x = 386

Number of children = 386

Number of adults = 287

9. Find the length of the arc shown in brown. Leave your answer in terms of 2 (1 point)
Nadusha1986 [10]

The length of the arc is 4π.

<u>Step-by-step explanation</u>:

Given,

  • Diameter = 24 ft
  • radius, r = diameter/2
  • r = 24/2 = 12 ft
  • central angle, ∅ = 60°

Arc length = ∅/360° (2πr)

⇒ 60°/360° (2π\times12)

⇒ 24π/6

⇒ 4π

∴ The length of the arc is 4π.
