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

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.

Find the missing value. Hint: Use the number line to find the missing value. -9-+ blank = -3
Answer:
-9 + 6 = -3
Step-by-step explanation
A negative number plus a positive number gets a higher negative number. For example, -6 + 1 = -5. Since the positive number is more than the negative number, think of it like subtraction. 6 - 1 = 5, so -6 + 1 = -5. So the answer to -9 + 6 is -3.

Step-by-step explanation:
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)

∑x=47.1, ∑y=104, ∑xy=616.24, ∑x²=329.12, ∑y²=1239
Now to find the coefficient determination ( r² )
we need to first find r
r = { n(∑xy) - (∑x)(∑y) } / { √( [n∑x² - (∑x)²] [n∑y² - (∑y)²] )
so we substitute
r = { 10(616.24) - (47.1)(104)} / { √( [10(329.12) - (47.1)²] [10(1239) - (104)²] )
r = 1264 / 1299.45
r = 0.97
now the coefficient determination is ( r² )
so coefficient determination = r²
= (0.97)²
= 0.9409 ≈ 1.00 (integer)
Therefore the coefficient determination of dataset B is 1.00

4. Mr. Ledic works in a coffee shop approximately nine miles from her apartment. She
bikes every day from her apartment to the coffee shop and then back to her
apartment in the evening. On her way to work, she always stops halfway through to
meet her best friend at a park. If the distance from Mr. Ledic's apartment to the
park is (5x + 6) miles and the trip from the park to the coffee shop is (23x - 8) miles
long, then what is the value of x?
Answer: 0.3929
Step-by-step explanation:
From the question, we are going to assume that the apartment, park and shop lies on a straight line.
We've been told that Mr. Ledic's apartment to the park is (5x + 6) miles and the trip from the park to the coffee shop is (23x - 8) miles while the coffee shop is nine miles from her apartment. This vsn be written as:
(5x+6)+(23x-8) = 9
28x+6-8=9
28x-2=9
28x=9+2
28x=11
x=11/28
x = 0.3929
Therefore, the value of x is 0.3929

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
/4 /4 Divide
2 = x

A-What fraction is shaded
B-what percentage is shaded
Answer: A) 2/3 is shaded. B) 66.67% is shaded.
Step-by-step explanation:
The whole big triangle holds 9 total triangles in it.
Out of the 9 triangles 6 of them are shaded so the fraction will be 6/9 which reduces to 2/3.
Now convert 2/3 to a decimal to find what percentage is shaded.
2/3 = 0.6666...
0.6666 * 100 = 66.666..
66.666 as a percent is 66.67%
Find the midpoint of XY, with X(-5,7) and Y (-7,5)
Answer:
The answer is
( - 6 , 6)Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
X(-5,7) and Y (-7,5)
The midpoint is
