Answer: 7 days
Step-by-step explanation:
Camille and Hiroki have decided to start walking for exercise. Camille is going to walk 7 miles the first day and 3 miles each day after that. Hiroki is too busy to walk on the first 2 days, so he decides to walk 5 miles each day until he has walked the same number of miles as Camille.
Camille will walk x days, so: 7 + 3(x-1) miles
Hiroki will walk the same miles, but 2 days less so: 5(x-2)
same amount of miles:
5(x-2) = 7 + 3(x-1)
5x - 10 = 7 + 3x - 3
5x - 3x = 10 + 7 - 3
2x = 14
x = 7
If Camille and Hiroki will have walked the same number of miles, how many days will Camille have walked?
Camille will have walked 7 days.
Answer:
Enthalpy of Vaporization of substance X = 489.15KJ/mol
Step-by-step explanation:
The Concept of Clausius Clapeyron equation is applied. This equation allows us to calculate the vapor pressure of a liquid over a some range of temperatures. The Clausius Clapeyron equation make use of the assumption that the heat of vaporization does not change as the temperature changes.
The question has data attached to it, I have added the other details and a step by step derivation and application of the Clausius Clapeyron equation was done.

Answer:
Step-by-step explanation:
Given that at a party there are at least two people.
We have to prove that there are two people who know the same number of other people there
Let n>2 be the no of people there
If possible let us assume each person knows different number of persons
The number of persons any one knows can vary from 0 to n-1
Hence these n people will have 0,1,2....n-1 persons known.
Consider the last person who knows n-1 people this means that he knows everyone in the party. So there cannot be any one who does not know any one or with known persons number as 0.
Thus we get a contradiction.
So there must be atleast two people who know the same number of people
