PLEASE HELP WITH THE PROBLEM ON THE ATTACHED FILE

Mathematics
1 answer:
prisoha [69]2 years ago
6 0

Answer:

6 : 1

Step-by-step explanation:

b - 3a / 9 = a /3

Cross multiply

3(b - 3a) = 9a

Expand

3b - 9a = 9a

Add 9a to both sides

3b = 9a + 9a

3b = 18a

Divide both sides by 3

b = 6a

Ratio of a : b

6 : 1

Estimate the perimeter of the figure to the nearest whole number.
Brrunno [24]

Answer:

<u>The perimeter of the pentagon ≅ 19 units (approximately)</u>

Step-by-step explanation:

Clockwise, starting from the base of the pentagon, we have:

  • Base of the pentagon or bottom side ≅ 4 units
  • 2nd side ≅ 3.75 units
  • 3rd side ≅ 3.75 units
  • 4th side ≅ 3.75 units
  • 5th side ≅ 3.75 units

In consequence,

Perimeter of the pentagon ≅ 4 + 3.75 + 3.75 + 3.75 + 3.75

<u>Perimeter of the pentagon ≅ 19 units</u>
