The radius of a circle is 19 km what is the circles area using 3.14 for pie
Answers
Answer:
1133.54 or 361 pi
Step-by-step explanation:
19^2*pi
Answer: 1133.54
Step-by-step explanation:
The formula to find the area of a circle is [tex]\pi[/tex] times the radius squared. The radius here is 19 so in order to square 19 you have to do 19x19 which is 361. Then, just multiply 361 by 3.14 and you should get 1133.54 as your final answer. Hope this helps!
A new pop-up restaurant serving high-end street tacos just opened and is expected to have high demand based on the chef's prior restaurant experience. The pop-up restaurant has only one window where customers order and receive their food. It takes an average of 5 minutes to serve a customer. There is no seating available so the customer exits the system after receiving their order.
Due to the creative marketing strategy of "hiding" the restaurant location, only 10 customers arrive per hour. There is no specific pattern to the distribution of time between arrivals or service times, but from historical data from prior pop-ups, the coefficient of variation for time between arrivals is 2.58 and service time is 0.75.

i. 0 minutes.
j. 90 minutes.
Answers
Answer:
1. c
2. f
3. d
Step-by-step explanation:
This type of queuing model is an example of "single-channel, single-phase" process.
However, from the information given:
The inter-arrival rate = 10 customers per hour
Arrival time = 6 minutes
Service time = 5 minutes
∴
utilization = service time/arrival time
= 5/6
Time on queue [tex]T_q = p \times \dfrac{utilization }{1 - utilization} \times \dfrac{Cv_a^2 -Cv_b^2}{2}[/tex]
[tex]T_q = 5 \times \dfrac{5/6 }{1 -5/6} \times \dfrac{(2.58^2 -0.75^2)}{2}[/tex]
[tex]T_q = 25 \times 3.60945[/tex]
[tex]T_q = 90.24 \\ \\ T_q \simeq 90 \ mins[/tex]
Thus, customer waiting in the queue line is;
[tex]= \dfrac{T_q}{q} \\ \\ = \dfrac{90}{6} \\ \\ \mathbf{=15}[/tex]
Thus, new customers will have to wait in a total time of;
= waiting time + service time
= 90 + 5
= 95 minutes.

Answers
Answer:
The answer would be y=-2x
Answer:
Equation y =2x represent the direct variation .
Step-by-step explanation:
Given : Equations y = 2x , y = x + 4 , y = 1/2x , y = 3/x .
To find : Which equation represents a direct variation.
Solution : We have given that equations
Direct variation : The statement "y varies directly as x," mean y and x always have the same ratio: k = .
Where k is constant of variation ,
We can write it as y = kx .
We can see that in equation y = 2x is the same as the above equation
On comparing k = 2.
Therefore, Equation y =2x represent the direct variation .

Neelam is pouring sand into a clear box to make sand art. The box is a right rectangular prism, and the base of the box is a right rectangular prism, and the base of the box is 7 in. by 2 1/2 in. She pours in red sand until the volume of the sand is 26 1/4 in.3. Then she pours in blue sand. Now the volume of the sand is 43 3/4 in.3. How much does the level of the sand rise when Neelam adds the blue sand?
Answers
The level of the sand rise when Neelam adds the blue sand is 1 inch if Neelam is pouring sand into a clear box to make sand art.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
It is given that:
Neelam is pouring sand into a clear box to make sand art.
The volume of the sand = 43 3/4 - 26 1/4
After simplification:
The volume of the sand = 17 1/2
The height of the sand = 17 1/2 ÷ (7x 2 1/2)
After solving:
The height of the sand = 1 inch
Thus, the level of the sand rise when Neelam adds the blue sand is 1 inch if Neelam is pouring sand into a clear box to make sand art.

For a right triangle, the cosine of an angle is the ratio between the length of the adjacent side and the length of the hypotenuse (the hypotenuse is the longest side of the triangle).
In this case,
cos(A) = adjacent / hypotenuse = 30 / 34 = 15/17
6)
For a right triangle, the cosine of an angle is the ratio between the length of the opposite side and the length of the hypotenuse.
In this case,
sin(A) = opposite / hypotenuse = 32 / 40 = 4/5
A way to remember sine, cosine, and tangent is SOHCAHTOA, where
SOH is Sine = Opposite / Hypotenuse
CAH is Cosine = Adjacent / Hypotenuse

The population of a town has been growing, following the equation P = 300t + 6000, where t is
years after 2010. The number of restaurants in the town has been growing according to the
equation R = 5t + 45.
Answers
Answer:
0.01 restaurants per person107.14 in persons per restaurantStep-by-step explanation:
P = 300 (2015-2010) + 6,000
P = 300(5) + 7,000 = 7 ,5 0 0
The number of restaurants prediction for 2015 is:
R = 5(2015-2010) + 45
R = 5(5) + 45 = 70
So per person, there would be:
70 Restaurants for 7,500 People that is: 70/7500
or 0.00933333333 which is 0.01 in nearest unit restaurants per person ←
per restaurant, there would be: 7500/70
or 107.14 in persons per restaurant

What is the slope of y = 4 - 2x?
Answers
Answer:
The slope is -2
Step-by-step explanation:
Rewrite in slope-intercept form.
The slope-intercept form is y = mx + b, where m
is the slope and b is the y-intercept.
[tex]y = mx + b[/tex]
Reorder 4 and -2x.
[tex]y = - 2x + 4[/tex]
Using the slope-intercept form, the slope is −2.
[tex]m = - 2[/tex]
Hence, the slope is -2.
The equation y = 4- 2x has a slope of -2.
The pitch of a direct equation is the measure of the term containing the independent variable( in this case," x").
In the equation y = 4- 2x, the measure of "x" is-2. thus, the pitch of the equation is-2.
We know equation is in slope-intercept form (y = mx + b), where "m" represents the slope.
The slope represents the rate of change of the dependent variable (y) with respect to the independent variable (x).
In this case, for every unit increase in x, the value of y diminishments by 2 units. This indicates a downcast pitch.
In summary, the equation y = 4- 2x has a slope of -2.
