the dry cleaning fee for 3 pairs of pants is $18. what is the constant of proportionality. How much will the dry cleaner charge
2 answers:
Answer:
Constant of proportionality is $6 for one pair and cost of dry cleaning 11 pairs of pants is $66.
Step-by-step explanation:
Dry cleaning fees is directly proportional to the charges of dry cleaning.
Cleaning fee ∝ Pairs of pants
Cleaning fee = k × Pairs of pants
where k is the proportionality constant.
If dry cleaning fee for 3 pairs of pants is $18 then from the equation given above
18 = k ×3
k =
SO the equation will be Cleaning fees = 6×Pairs of pants
For 11 pairs of pants,
Cleaning fees = 6×11 = $66
Therefore, constant of proportionality is $6 for one pair of pants and cost of dry cleaning 11 pairs of pants is $66.

Answer:
Proved
Step-by-step explanation:
From the given parameters, we have:
i.e. the length of each security numbers
i.e. 2 security numbers
Required
In 513 security numbers, 2 must have matching zeros
To do this, we make use of Pigeonhole principle.
First, we calculate the number of all security numbers not having matching zeros.
Each of the 9 digits can be selected in 2 ways.
2 ways implies that each digit is either 0 or not
So, total selection is:
Apply Pigeonhole principle
The principle states that: suppose there are n items in m containers, where , then there is at least one container that contains more than 1 item.
This means that if there are 512 security number without matching zeros, then there is 1 (i.e. 512 + 1) with matching zeros.
