Answer:
In this hotel there are 27 double rooms and 8 single rooms.
Step-by-step explanation:
We will consider the guests who stayed on double rooms as 'd' and the ones who stayed on single rooms as 's'. The sum of them should be the number of guests on the hotel. So we have:
s + d = 62
They need to be distributed in such a way that they'll fit in 35 rooms. The people who got on double rooms need to be divided by two, since two people will be on the same room. So we have:
s + d/2 = 35
Since we have two equations and two variables we can create a system of equations and solve it:
s+ d = 62
s + d/2 = 35
From the first equation we have:
s = 62 - d
Swaping this value on the second equation:
62 - d + d/2 = 35
62 -d/2 = 35
-d/2 = 35 - 62
-d/2 = -27
-d = -54
d = 54
Using that value we can solve for s:
s = 62 - 54 = 8
So they had 54 people staying on double rooms and 8 people staying on single rooms. Since 54 people stayed on double rooms there are 27 double rooms.

Answer:
10.6
Step-by-step explanation:
1. First, we need to find which digits √(113) is between, and that would be 10 and 11.
2. Okay, so √(113) is between 10 and 11, meaning 113 is between 100 and 121.
3. Since 113 is a little over half between 100 and 121, let's multiply 10.6 by 10.6 to see how close we are to 113:
4. 112.36 is pretty close to 113, therefore, the dot on the number-line should be placed at 10.6.
