Liono4ka [1.6K]

The number of plates is an illustration of permutation and combination

The number of plates is 2592

<h3>How to determine the number of plates</h3>

The range is given as: AVVJ 144 To: BVNP 199 (exclusive)

From the range, we have the following highlights:

  • The first letter can be either A or B (i.e. 2 letters)
  • The second letter can be only V (i.e. 1 letter)
  • The third letter can be from W to M (24 letters)
  • There are 54 numbers between 144 and 199

The number of plates (n) is then calculated as:

n = 2 * 1 * 24 * 54

Evaluate the product

n = 2592

Hence, the number of plates (n) is 2592

so the answer is 1/6 ÷ 1/2

MariettaO [177]

Based on the length and width of the rectangular lawn, and the percentage the man has mowed, the strip width would be 40.5 m.

<h3>what is the width of the strip mowed already?</h3>

first, find the area of the lawn:

= 100 x 200

= 20,000 ft²

the area mowed is:

= 40.5% x 20,000

= 8,100 ft²

the width is therefore:

= 8,100 / 200

= 40.5 m
