You are building a scale model of a fishing boat. The boat is 62 ft long and 23 ft wide. The
Temka [501]

The wide of the model should be approximately 5.194 inches

Step-by-step explanation:

You are building a scale model of a fishing boat

  • The boat is 62 ft long
  • The boat is 23 ft wide
  • The model will be 14 in long

We need to find how wide should it be

∵ The boat is 62 feet long

∵ The model of the boat is 14 inches long

- That means 14 inches represents 62 feet

By using the ratio method

→ Actual (ft)    :    Model (in)

→ 62               :    14

→ 23               :     x

By using cross multiplication

∵ 62 × x = 23 × 14

∴ 62 x = 322

- Divide both sides by 62 to find x

∴ x ≅ 5.194

∵ x represents the wide of the model

∴ The wide of the model is approximately 5.194 inches

The wide of the model should be approximately 5.194 inches

The extreme water slide forms a 20 angle with the tower it leans against 80 feet above the ground find the length of the slide x
GarryVolchara [31]

Answer:

85.1 ft

Step-by-step explanation:

The extreme water slide forms a 20 angle with the tower it leans against 80 feet above the ground find the length of the slide x

We solve using the Trigonometric function of Cosine

cos y = adjacent/hypotenuse

y = angle = 20°

Adjacent = 80 ft

Hypotenuse = ?

cos 20 = 80/Hypotenuse

Hypotenuse = 80/cos 20

x = 85.134221798 ft

Approximately = 85.1 ft

Length of the slide = 85.1 ft
