The Classic Hotel provides room service for its guests. The process for room service begins with a room service manager who takes orders of food and beverages by phone and transmits them to the kitchen and the bar at an average of 2 minutes per order. Each food order is prepared in an average of 15 minutes in the kitchen. There are five equally competent chefs in the kitchen, each of whom prepares complete orders, working in parallel. The one bartender takes 3 minutes to fill each beverage order, and works in parallel with the kitchen. When the kitchen and bar order are both ready, a waiter takes them to the room. There are eight waiters to provide the service, and each order takes 20 minutes for a waiter to put together and deliver. What is the capacity rate of each activity

2
find the equation that relates v and w.
Provide your answer below:

Given parameters:
y varies directly as w;
This interpreted implies that as y increases, we increases by a certain factor or amount;
So, y ∝ w
y = kw
where k is the constant of proportionality
Now, given that y = 8 and w = 2
Input in the equation to solve for k;
8 = k x 2
Solving k gives, k = 4
Now to the second part,
if v is directly proportional to w;
v = k w
So v = 4w
The equation that relates v to w is v = 4w

The correct options are:
It has only 1 line of reflectional symmetry.
A line of symmetry will connect a vertex and a midpoint of an opposite side.
What is a reflection?A reflection is a type of transformation that involves flipping a shape, known as the preimage, over a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you flipped the form over the line in order to graph a reflection.
A regular heptagon has one line of reflectional symmetry, which passes through the midpoint of one side and the opposite vertex.
This line divides the heptagon into two congruent halves.
Additionally, there are six lines of symmetry that connect a vertex and the midpoint of the opposite side.
Each of these lines bisects the angle at the vertex and divides the heptagon into two congruent parts.

If positive integer number n has exactly 8 divisors, what is the least number of divisors can n^2 have?
Answer:
The simpler case is the number:
n = a^7, where a is prime.
We use this so we avoid having cross numbers by multipliying different prime numbers. because for example lets compare:
2^2 = 4 has 3 divisors, 4, 2 and 1.
(4*4) = 16 has the divisors: 1, 2, 4, 8 and 16. (5 divisors).
Now let's mix primes:
2*3 = 6 has 3 divisors, 3, 2 and 1.
6*6 = 36
(3*2*1)*(3*2*1) = 36
then the divisors are:
3*3, 3*2, 3*1, 2*2, 2*1, 1*1, 3*2*2, ..., etc.
You can clearly see that this has a lot more divisors than the previous case.
Then returning to the answer:
a^7 can be divided by a, a^2, a^3, ..., and by itself, a^7 (and 1, so we have exactly 8 divisors).
Now, we can write:
n^2 = (a^7)^2 = (a^(2*7)) = a^14.
By the same logic that was used above, a^14 has 14 + 1 divisors.
Then the smallest number of divisors possible is 15.

Marks age next year will be three times jims age from 2 years ago. If the sum of their ages now is 21, how old are they? plz help, I am gonna get killed by my parents.
Answer: Mark is 14 and Jim is 7.
Step-by-step explanation: It says that next year Mark will be threee times older than Jim was 2 years ago.
The wrk is:
7-2=5(Jims age 2 years ago)
5x3=15
15-1=14(you subtract 1 because Mark's current age is 14 because it says that next year it will be 3 times Jim's)

Find the inverse for the relation.{ (-5,7), (-6, -8), (1, -2), (10, 3) }
Answer:
{(7, -5), (-8, -6), (-2, 1), (3, 10)}Step-by-step explanation:
The inverse for the relation (a, b) is (b, a).
Therefore the inverse for the relation
{(-5, 7), (-6, -8), (1, -2), (10, 3)}is
{(7, -5), (-8, -6), (-2, 1), (3, 10)}{(7, -5), (-8, -6), (-2, 1), (3, 10)} is the inverse for the relation { (-5,7), (-6, -8), (1, -2), (10, 3) }.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given, few coordinates { (-5,7), (-6, -8), (1, -2), (10, 3) }
We need to find inverse relation of these coordinates.
Since, The inverse of a relation is a relation obtained by interchanging or swapping the elements or coordinates of each ordered pair in the relation.
Inverse relation in sets can be defined using the ordered pairs. The domain and range of an inverse relation can be written by swapping the domain and range of that relation. That means the domain of relation will be the range of its inverse, and the range of relation will be the domain of its inverse.
The inverse for the relation (a, b) is (b, a).
Therefore, the inverse for the relation { (-5,7), (-6, -8), (1, -2), (10, 3) } is:
{(7, -5), (-8, -6), (-2, 1), (3, 10)}

2x + y = 5
4x - 2y = 6
Answer:
Assuming you want to solve for x,
x = 2
Step-by-step explanation:
2x + y = 5
Solve for y
y = 5 - 2x
4x - 2y = 6
Solve for y
y = -3 + 2x
Since both these equations equal y, they must equal each other.
Make an equation for these to equal each other.
Then solve for x
5 - 2x = -3 + 2x
+ 2x + 2x Add
5 = - 3 + 4x
+ 3 +3 Add
8 = 4x

3. A square has vertices (0,0),(5,2).(3,7), and (-2,5). Which of these statements is true?
A. The square's side length is 5.
B. The square's side length is between 5 and 6.
C. The square's side length is between 6 and 7.
D. The square's side length is 7
Answer:
B. The square's side length is between 5 and 6.
Step-by-step explanation:
We are given a square with vertices
A(0,0), B(5,2), C(3,7), and D (-2,5)
We solve using the Formula
√(x2 - x1)² + (y2 - y1)²
Where we have (x1, y1) and (x2, y2)
For AB
A(0,0), B(5,2)
= √(5 -0)² + (2 - 0)²
= √5² + 2²
= √25 + 4
= √29
= 5.3851648071
For BC
B(5,2), C(3,7),
= √(3 - 5)² + (7 - 2)²
= √-2² + 5²
= √4 + 25
= √29
= 5.3851648071
For A D
A(0,0),D (-2,5)
√(-2- 0)² + (5 - 0)²
= √-2² + 5²
= √4 + 25
= √29
= √5.3851648071
For CD
C(3,7), D (-2,5)
√(-2 - 3)² + (5 - 7)²
= √-5² + -2²
= √25 + 4
= √29
= 5.3851648071
The lengths of the sides of the square is equal to each other.
Therefore, the statement that is true about this square is option
B. The square's side length is between 5 and 6.

Answer:
[tex]P(business\ or\ personal) = 69.8\%[/tex]
[tex]P(Not(business\ or\ personal)) = 30.2\%[/tex]
Step-by-step explanation:
The question has missing details; however, the giving parameters are:
[tex]P(business) = 45.8\%[/tex]
[tex]P(personal) = 54\%[/tex]
[tex]P(both) = 30\%[/tex]
Solving (a): Business or Personal
This is calculated as follows:
[tex]P(business\ or\ personal) = P(business) + P(personal) - P(both)[/tex]
[tex]P(business\ or\ personal) = 45.8\% + 54\% - 30\%[/tex]
[tex]P(business\ or\ personal) = 69.8\%[/tex]
Solving (b): Not business or personal
This is calculated using complements of probability;
[tex]P(Not(business\ or\ personal)) = 1 - P(business\ or\ personal)[/tex]
[tex]P(Not(business\ or\ personal)) = 1 - 69.8\%[/tex]
[tex]P(Not(business\ or\ personal)) = 30.2\%[/tex]
