Andrew rents rooms in his hotel for an average of $97 per night. The variable cost per rented room is $36. His fixed costs are $52,000 per month. How many rooms does he have to rent per month in order to break even?
Answer:
853 rooms
Step-by-step explanation:
If someone just opens the door with the intent to stay, Andrew has variable costs to pay which come off the 97 dollars. So his actual profit is 97 - 36 = 61 dollars. So how many rooms in total does he have to rent?
52000 / 61 = 853 rounded.
Is this realistic? The average month has 30 days
853 / 30 = 29 rooms rounded
Each room of 29 would have to be rented every night. I would say he better sell the hotel and go into something else.
Help me please and thank you

The domain tells you if there are any restrictions on the x's
The -5 in the function tells us that it has moved 5 units RIGHT from the original parent function. Because of this, any x coordinates have to be bigger or equal to 5!
So, the domain of this function is x >/ 5

In a group of 25 people, only three languages are spoken – English, Spanish and German. If there is at least one person who speaks all the three languages, how many people can interact with each other in English and German? 4 people speak two languages but do not speak Spanish One fifth of the group speaks more than one language.
Answer:
x + a=5
Step-by-step explanation:
Let
number of people who speak only English = E
the number of people who speak only German = G
the number of people who speak only Spanish = S
the number of people who speak only English & German but not Spanish = x
the number of people who speak only English & Spanish but not German = y
the number of people who speak only German & Spanish but not English = z;
the number of people who speak only German & Spanish & English = a
Find the the value of (x + a).
Statement 1: 4 people speak two languages but do not speak Spanish.
x = 4.
x+a
Value for a is unknown.
(x + a). Insufficient.
Statement 3: One-fifth of the group speaks more than one language.
x + y + z + a
= 25/5
= 5
value of (x + a) unknown
Insufficient.
Putting (1) and (2) together
x + y + z + a = 5
x = 4 and a=1,
we have only one possible solution from
x + y + z + a = 5
x + a
= 4 + 1
= 5.
Sufficient.
Which statement is true about the function represented by this graph?
Answer: Choice D)
The function has a range of all real numbers less than or equal to 2.
=======================================================
Explanation:
Let's go through the answer choices to see which are true, and which are false.
A) This is false because (0,-2) is a y intercept, and not an x intercept. A zero of a function is always an x intercept.B) This is false. The curve peaks at the vertex (2,2) showing we have a max point, and not a min point.C) This is false. A function can have at most one y intercept. If it had more than one y intercept, then it wouldn't be a function (since the input x = 0 leads to more than one output).D) This is true. The range is the set of possible y outputs. We see that y = 2 is the largest output, which occurs at the vertex. We can get anything smaller than this y value. Therefore, the range is the set of y values such that [tex]y \le 2[/tex]Answer:
option D
Step-by-step explanation:
THE FUNCTION HAS A RANGE OF ALL REAL NUMBERS LESS THAN OR EQUAL TO 2

How do you solve
Answer:
x = 1/2
Step-by-step explanation:
3 - 2(x - 1) = 2 + 4x
3 - 2x + 2 = 2 + 4x
-2x + 5 = 2 + 4x
-2x - 4x = 2 - 5

Combine the radicals. 2√24+5√54 A) 53√6 B) 5√6 C) 19√6 D) 93√6
Answer:
The answer is option CStep-by-step explanation:
2√24 + 5√54
To combine the radicals first make sure the radicals have the same square root
That's
For 2√24[tex]2 \sqrt{24} = 2 \sqrt{4 \times 6} = 2 \times 2 \sqrt{6} [/tex][tex] = 4 \sqrt{6} [/tex]For 9√54[tex]5 \sqrt{54} = 5 \sqrt{9 \times 6} = 5 \times \sqrt{9} \times \sqrt{6} [/tex][tex] = 5 \times 3 \times \sqrt{6} [/tex][tex] = 15 \sqrt{6} [/tex]Since they have the same square root we can combine them
That's
[tex]4 \sqrt{6} + 15 \sqrt{6} = (4 + 15) \sqrt{6} [/tex]We have the final answer as
[tex]19 \sqrt{6} [/tex]Hope this helps you
What is the square root of 100?
Answer:
10
Step-by-step explanation:
Square root of 100 is 10
Answer:
10
Step-by-step explanation:
The square root of 100 is written as 2√100=√100=±10.
So it is 10. Also, 10 times 10 equals 100, so it checks out.
A square root is just two of the same numbers added together to equal a specific number.
Jorge walked 25 steps north. then he walked 75 steps south what is Jorges final position
Answer:
If Jorge goes up 25 (positive) and then goes 75 steps south (negative). Then you have to calculate 25-75. This equals -50. We know negative distance is south so he's final position will be 50 steps south.

3 cans of worms plus 2 extra worms. Cecil
brings 2 cans of worms. If they have a
total of 65 worms and each can contains
the same number of worms, how
many worms are in each can?
Answer:
7
Step-by-step explanation:
If we call the number of worms in a can x, we can write:
4x + 3x + 2 + 2x = 65
9x + 2 = 65
9x = 63
x = 7 worms

Step-by-step explanation:
elizas backpack weights 18 7/8 pounds with her math book in it. without her math book, her backpack weighs 14 7/9 pounds
I'm assuming your trying to find the weight of the math book so here it is:
Answer:
4 5/36
Step-by-step explanation:
You'd have to do 18 7/8 - 14 7/9 but you can't subtract them yet because they don't have common denominators. So, you have to multiply the 7/8 by 9 and the 7/9 by 8. Then you would get 63/72 and 56/72. Then you put that into the equation and get, 18 63/72 - 14 53/72. If you subtract those, you get the answer, 4 10/72. Which can be simplified as 4 5/36.

why is gravitational force between two object usually unnoticeable
Answer:
gravitational attraction is based upon mass.More the mass more the force.When the object is as big as a moon it has a very less gravity.When we are talking about small objects like 2 pencils the force exists but is so weak that no noticabke movement takes place
Answer:
To notice that force, the objects have to have a big mass and be close to each others.
Generally in eveydays life, you don't notice this force since it is weak but that doesn't mean it does't exist.
If you go the space, you can notice this force since planets have big mass. If you get close to the gravitational field of a planet, you will feel a force that is pulling you toward the planet.

2c+17.6 =6 / 4 SOLVE give your answer as a decimal get brainly
Answer:
-8.05
Step-by-step explanation:
In order to solve for C you first have to subtract 17.6 from both sides.
2c=(6/4)-17.6
6/4 is 1.5
1.5-17.6=-16.1
2c=-16.1
c=-8.05
Answer:
1.5
Step-by-step explanation:
2c+17.6=6/4
2c+176/10=6/4
2c+88/5=6/4
2c=6/4-88/5
2c=30-352/20
2c=-322/20
2c=-161/10
c=-8.05
Proof:
2c+17.6=6/4
2(-8.05)+17.6=6/4
-16.1+17.6=6/4
1.5=1.5
