How do you solve x + 1/4x = 15.

Answers

x + 1/4x = 15
4/4x + 1/4x = 15
5/4x = 15
5x = 60
x = 12

x+(1/4)*x = 15 // - 15

x+(1/4)*x-15 = 0

5/4*x-15 = 0 // + 15

5/4*x = 15 // : 5/4

x = 15/5/4

x = 12

Find the area of each sector.
*Geometry

Answers

The area of the sector in the diagram is 1805π/8 km².

What is area?

Area is the region bounded by a plane shape.

To calculate the area of the sector, we use the formula below

Formula:

  • A = πr²∅/360......................... Equation 1

Where:

  • A = Area of the sector
  • r = Radius of the sector
  • ∅ = Angle of the sector

From the question,

Given:

  • r = 19 km
  • ∅ = 225°

Substitute these values into equation 1

  • A = π×19²×225/360
  • A = 1805π/8 km²

Hence, the right option is B. 1805π/8 km²
