What is the slope of the line y = − 4?
Answer:
0
Step-by-step explanation:
the equation describes a horizontal line with a y-intercept of -4. as the line is horizontal, the slope is 0. The slope is 0 and the y-intercept is -4.
Answer:
0
Step-by-step explanation:
This equation is written in slope-intercept form. This form is y=mx+b, where m is the slope and b is the y-intercept. In this equation, there is no x. This must mean that m is 0 because the only number times x that could make x=0 is 0. If this line was drawn it would be a straight horizontal line, since it is not changing at all the slope is 0.
Find the slope and the y-intercept of the graph of y=11+1.5x.

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?
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.

Mrs. Flores asked her students to write a number, its opposite, and its absolute value, in that order. Four of her students turned in their work below.
Student Work
Keenan -1285, -1285, 1285
Sarah 1416, -1416, 1416 Ahab -1383, 1383, -1383
Ji-yoon 1574. -1574, -1574
Which student correctly listed a number, its opposite, and its absolute value in the correct order?
Answer:
Sarah is correct
Step-by-step explanation:
Required
Which of the students is correct
Let a number be x,
Given what the teacher asked the students to do, the solution is:
[tex]Number = x[/tex]
[tex]Opposite = -x[/tex]
[tex]Absolute = |x|[/tex]
Only Sarah got this correctly; others are incorrect.
The proof is as follows.
For Sarah
[tex]Number = 1416[/tex]
[tex]Opposite = -1416[/tex]
[tex]Absolute =|1416| = 1416[/tex]
So, the numbers will be: 1416, -1416 and 1416
Other students are incorrect
¿que es una estadística?
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.

3. For new customers, how long do they have to wait in total before they leave with their food?
a. 45 minutes.
b. 20 minutes.
c. 50 minutes.
d. 95 minutes.
e. 15 minutes.
f. 100 minutes.
g. 40 minutes.
h. 10 minutes.
i. 0 minutes.
j. 90 minutes.
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.

A circle is centered at (-4, 6) and has a radius of 9. What is the equation of the circle?
Answer:
C
Step-by-step explanation:
The standard equation for a circle is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where (h, k) is the center of the circle and r is the radius.
We want to find the equation of a circle that is centered on (-4, 6) and has a radius of 9 units.
Therefore, (h, k) = (-4, 6).
And r = 9.
By substitution:
[tex](x-(-4))^2+(y-(6))^2=(9)^2[/tex]
Simplify. Hence, our equation is:
[tex](x+4)^2+(y-6)^2=81[/tex]
Our answer is C.
Answer:
Solution given:
centre (h,k)=(-4,6)
radius [r]=9
we have
equation of a circle
(x-h)²+(y-k)²=r²
(x+4)²+(y-6)²=9²
(x+4)²+(y-6)²=81 is a required equation
What is the slope of y = 4 - 2x?
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.

Answer:
5) arccos A = 28°

Step-by-step explanation:
5) cos A = 30/34
6) sin A = 32/40
5)
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
TOA is Tangent = Opposite / Adjacent

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.
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

Step-by-step explanation:
-6x + 38 > -9
Subtract 38 from both sides;
-6x+38-38>-9-38
Simplify:
-6x>-47
Multiply both sides by (-1) ( reverse the inequality)
(-6x)(-1)<(-47)(-1)

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!
