The number of ways we can have five people line up at a checkout counter in a supermarket is 120 ways.
Since order is important, we use permutations to answer the question
<h3>What are permutations?</h3>
These are the number of ways, x of arranging n objects. It is given by ⁿPₓ = n(n - 1)(n - 2)(n - 3)...(n - x + 1) = n!/(n - r)!
Since we have five people to be arranged in line, there are 5 people to be arranged in 5 places.
So, there are 5 places for the first person, 4 places for the second person, 3 places for the third person, 2 places for the fourth person and 1 place for the last person.
So, we number of permutations or number of ways of arranging them in line is ⁵P₅ = 5 × 4 × 3 × 2 × 1
= 120 ways
So, the number of ways we can have five people line up at a checkout counter in a supermarket is 120 ways.

Answer:
Sure
Step-by-step explanation:
Are you asking for 3ft and 4in in centimeters? You complicated the sentence a bit. :)
A farmer has order the fields from least area to greatest area is,
Soybean field < Cornfield < Wheat field.
Based on the given conditions,
A farmer has a soybean field with an area = 55 square meters
A farmer has a corn field with an area = 58 square meters
He also has a wheat field that is 52 times the size of the soybean field.
So,
We can write,
52 times the size of the soybean field.
That means,
= 55 * 52
Calculate the product or quotient,
= 2860
Wheat field = 2860
Hence,
Soybean field = 55
Cornfield = 58
Wheat field = 2860
Soybean field < Cornfield < Wheat field
Therefore,
A farmer has order the fields from least area to greatest area is,
Soybean field < Cornfield < Wheat field.
