A customer has $10 to spend at the concession stand. Hotdogs cost $2 each and drinks cost $2.50 each. Graph the inequality that illustrates this situation. Use the space below to explain what the answer means.
Answers
Answer:
Please refer to the graph in the attached area.
Step-by-step explanation:
Given:
Total money available with the customer is $10.
Cost of each hotdog is $2.
Cost of each drink is is $2.50.
To find:
The graph of inequality.
Solution:
Let number of hotdogs bought = [tex]x[/tex]
Total cost of hotdogs = [tex]2x[/tex]
Let number of drinks bought = [tex]y[/tex]
Total cost of drinks = [tex]2.5y[/tex]
Total cost = [tex]2x+2.5y[/tex]
And total money available is $10.
So, the total cost calculated above must be lesser than or equal to $10.
Hence, the inequality is:
[tex]2x+2.5y<10[/tex]
Also there will be two conditions on variables [tex]x[/tex] and [tex]y[/tex]:
[tex]x\ge0\\y\ge0[/tex]
To graph this, let us find the points on the equivalent equation:
[tex]2x+2.5y = 10[/tex]
Finding two points on the equation.
First put x = 0 [tex]\Rightarrow[/tex] y = 4
Then put y = 0, [tex]\Rightarrow[/tex] x = 5
So, two points are (0, 4) and (5, 0).
Now, plotting the line.
Having point (1,2) in the inequality:
2 + 5 < 10 (True) hence, the graph of inequality will contain the point (1,2)
Please refer to the graph of inequality in the attached graph.

Please help ASAP!!! Thank you so much!!! Just want confirm my answer it is y=150x-50. A concession stand at a football game took in $100 after being open for 1 hour. After 3 hours, the stand had taken in $400. Assuming a linear function, write an equation in the form y=mx+b that shows the revenue earned from being opened for x hours.
Answers
Answer: You have the correct answer. It is y = 150x-50
Nice work on getting the correct answer. For anyone curious, the explanation is below.
=============================================
x = number of hours the stand is open
y = amount earned
(1,100) is from the fact the stand is open 1 hour and earns $100
(3,400) is due to the stand earning $400 after 3 hours.
Slope Formula
m = (y2 - y1)/(x2 - x1)
m = (400-100)/(3-1)
m = 300/2
m = 150 is the slope, and it is the amount earned per hour. It is the rate of change.
Use m = 150 and (x,y) = (1,100) to find the value of b as shown below
y = mx+b
100 = 150(1) + b
100 = 150 + b
100-150 = b
-50 = b
b = -50 is the y intercept and it is the starting amount they earn. The negative earning indicates that they spent $50 to set up the stand, which is the cost of buying the food, equipment, etc.
So we have m = 150 as the slope and b = -50 as the y intercept.
Therefore, y = mx+b turns into y = 150x-50.
-------
As a check, plugging in x = 1 should lead to y = 100
y = 150x-50
y = 150(1)-50
y = 150-50
y = 100 and indeed it does
The same should be the case with (3,400). Plug in x = 3 and we should get y = 400
y = 150x-50
y = 150(3)-50
y = 450-50
y = 400, we have confirmed the answer by showing that the line y = 150x-50 goes through the two points (1,100) and (3,400).
The equation for revenue earned from being opened for x hours will be y=150x-50 so it is absolutely correct.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Given,
$100 for 1 hour
So,
x = 1 and y = 100
And,
$400 for 3 hour
So,
x = 3 and y = 400
Now the slope of the linear equation is given by
m = difference in ys coordinate / difference in xs coordinate
m = (400 - 300)/(3-1) = 150
So equation become
y = 150x + b
Now put (3,400) to find out b
400 = 150(3) + b
b = -50
So, equation
y = 150x - 50
Hence " The equation for revenue earned from being opened for x hours will be y=150x-50".

A sample of 4 different calculators is randomly selected from a group containing 42 that are defective and 20 that have no defects. What is the probability that all four of the calculators selected are defective? No replacement. Round to four decimal places.
Answers
Answer: = approx 0.2006
Step-by-step explanation:
The probability that first 1 randomly selected calculator is defective is
P(1st defect)= 42/(42+20)=42/62=21/31
If the first calculator is defective the residual number of defective calculators is 42-1=41. The residual total number number of calculators is 62-1=61
So the probability that second calculator is defected
P(2nd defective)=41/61
If both previous calculators are defective the residual number of defective calculators is 42-2=40. Total residual number of calculators is 62-2=60
So the probability that third calculator is defected
P(3rd defective)=40/60=2/3
Finally the probability that also fourth calculator is defective is 39/59
P(4th defective)=39/59
The resulted probability that all 4 calculators are defective is
P(all 4 are defective)= P(1st defect)* P(2nd defect) * P(3rd defect)* P(4th defect)=21*41*2*39/(31*61*3*59)=67158/334707=0.200647... = approx 0.2006

The given point is
[tex]\left(7,\dfrac{2\pi}{3}\right)[/tex]
We need to find the rectangular coordinates of the given point.
If a polar coordinate is [tex](r,\theta)[/tex], then
[tex]x=r\cos theta[/tex]
[tex]y=r\sin theta[/tex]
In the given point [tex]\left(7,\dfrac{2\pi}{3}\right)[/tex],
[tex]r=7,\theta=\dfrac{2\pi}{3}[/tex]
Now,
[tex]x=7\cos \dfrac{2\pi}{3}[/tex]
[tex]x=7\cos \left(\pi-\dfrac{\pi}{3}\right)[/tex]
[tex]x=-7\cos \left(\dfrac{\pi}{3}\right)[/tex]
[tex]x=-7\left(\dfrac{1}{2}\right)[/tex]
[tex]x=-\dfrac{7}{2}[/tex]
and,
[tex]y=7\sin \dfrac{2\pi}{3}[/tex]
[tex]y=7\sin \left(\pi-\dfrac{\pi}{3}\right)[/tex]
[tex]y=7\sin \left(\dfrac{\pi}{3}\right)[/tex]
[tex]y=7\left(\dfrac{\sqrt{3}}{2}\right)[/tex]
[tex]y=\dfrac{7\sqrt{3}}{2}[/tex]

Answers
Answer:
0.5 seconds and 1.5 seconds.
Step-by-step explanation:
h(t) = -16t^2 + 32t + 2
14 = -16t^2 + 32t + 2
16t^2 - 32t - 2 + 14 = 0
16t^2 - 32t + 12 = 0
8t^2 - 16t + 6 = 0
4t^2 - 8t + 3 = 0
(2x - 3)(2x - 1) = 0
2x - 3 = 0
2x = 3
x = 3/2
x = 1.5
2x - 1 = 0
2x = 1
x = 1/2
x = 0.5
So, the ball was at 14 feet at 0.5 seconds and 1.5 seconds.

Lydia buys 5 pounds of apples and 3 pounds of bananas for a total of $8.50. Ari buys 3 pounds of apples and 2
pounds of bananas for a total of $5.25. This system of equations represents the situation, where x is the cost per
pound of apples, and y is the cost per pound of bananas.
5x + 3y = 8.5
3x + 2y = 5.25

What is the price per pound of apples? $
What is the price per pound of bananas?
Answers
Answer:
price per pound of apple = $1.25
price per pound of banana = $0.75
Step-by-step explanation:
Your first question is what value should you multiply the second equation by in order to eliminate the y terms.
The number should be 3. Let us multiply the first equation by 2 and the second equation by 3 and see how y will be eliminated.
10x + 6y = 17...............(i)
9x + 6y = 15.75...........(ii)
10x - 9x = x
6y - 6y = 0
17 - 15.75 = 1.25
x = 1.25
let us find y
10x + 6y = 17...............(i)
10(1.25) + 6y = 17
12.5 + 6y = 17
6y = 17 - 12.5
6y = 4.5
divide both sides by 6
y = 4.5/6
y = 0.75
In order to eliminate y term from the system of equations we multiply equation 2 by -3.
The price per pound of apple is 1.25 dollars and the price per pound of bananas is 0.75 dollars.
Given equations,
[tex]5x + 3y = 8.5[/tex].........(1)
[tex]3x + 2y = 5.25[/tex].......(2)
Here x is the cost per pound of apples, and y is the cost per pound of bananas.
According to the question, multiply the first equation by 2, we get
[tex]10x+6y=17[/tex].....(3)
So, in order to eliminate y term from the system of equations we multiply equation 2 by -3, we get
[tex]-9x-6y=15.75[/tex].....(4)
Now Adding (3) and (4) equation, we get
[tex]x=1.25[/tex]
Putting the above value of x in equation 3 we get,
[tex]10\times1.25+6y=17\\12.5+6y=17\\6y=17-12.5\\6y=4.5\\y=\frac{4.5}{6} \\y=0.75[/tex]
Hence the price per pound of apple is 1.25 dollars and the price per pound of bananas is 0.75 dollars.

which of the following descriptions represent the transformation shown in the image? Part 1d
Answers
Answer:
(C) Translation of 2 units right, 1 up, and a reflection over the y-axis.
Step-by-step explanation:
Ideally, we are looking for a reflection of the red image over the y-axis, and to do that, we can see how we need to move the black image.
In order for points Q and Q' to be a reflection of each other, they need to have the same y value, and be the exact same distance from the y axis, so the point that Q has to be at is (-1,-3).
Q is right now at (-3,-4) so we can translate this.
To get from -3 to -1 in the x-axis, we go right by 2 units.
To get from -4 to -3 in the y-axis, we go up one unit.
Now, if we reflect it, the triangles will be the same.
Hope this helped!
Answer:
C.
Step-by-step explanation:
When you study the images, it is clear that the black triangle has to be reflected over the y-axis to face the same direction as the red triangle. So, choice A is eliminated.
Once you reflect the black triangle across the y-axis, you have points at (-1, -1), (3, -4), and (3, -2). Meanwhile, the red triangle's coordinates are at (-3, 0), (1, -3), and (1, -1). From these points, you can tell that the x-values differ by 2 units and the y-values differ by 1 unit.
All of these conditions match the ones put forth in option C, so that is your answer.

A catering company is catering a large wedding reception. The host of the reception has
asked the company to spend a total of $454 on two types of meat: chicken and beef. The
chicken costs $5 per pound, and the beef costs $ 7 per pound. If the catering company
buys 25 pounds of chicken, how many pounds of beef can they buy?
Answers
The answer is 47 pounds
Explanation:
1. First, let's calculate the amount of money that was spent on chicken
$5 per pound of chicken x 25 pounds = $125
2. Calculate the amount of money left to buy beef by subtracting the total spend on chicken to the total of the budget.
$454 (total) - $125 (chicken) = $329
3. Calculate how many pounds of beef you can buy with the money left by dividing the money into the price for one pound.
$329 / $7 = 47 pounds

To make the negative true, we need the angle to be in the third or fourth quadrants (i.e., 5π/4 and 7π/4). These are two of the answer choices.

Using the unit circle, determine the value of cos(945°).
Answers
========================================================
Explanation:
The angle 945 degrees is not between 0 and 360. We need to adjust it so that we find a coterminal angle in this range. To do this, subtract off 360 repeatedly until we get into the right range
945 - 360 = 585, not in range, so subtract again
585 - 350 = 225, we're in range now
Since 945 and 225 are coterminal angles, this means cos(945) = cos(225)
From here, we use the unit circle. Your unit circle should show the angle 225 in quadrant 3, which is the lower left quadrant. The terminal point here at this angle is [tex]\left(-\frac{\sqrt{2}}{2}, -\frac{\sqrt{2}}{2}\right)[/tex]
The x coordinate of this terminal point is the value of cos(theta). Therefore [tex]\cos(225^{\circ}) = -\frac{\sqrt{2}}{2}[/tex] and this is also the value of cos(945) as well
Using the periodic property of cos function, you can evaluate the value of cos(945°).
The value of cos(945°) is given by:
[tex]cos(945^\circ) = -\dfrac{1}{\sqrt{2}}[/tex]
Given that:To find the value of cos(945°) using the unit circle.What are periodic functions?
A function returning to same value at regular intervals of specific length(called period of that function).
It is [tex]2\pi[/tex]
Thus, we have:
[tex]cos(x) = cos(2\pi +x) \: \forall \: x \in \mathbb R[/tex]
Using the periodic property of cosine:[tex]cos(945^\circ) = cos(2 \times 360^\circ + 225^\circ) = cos(2\pi + 2\pi + 225)\\ cos(945^\circ) = cos(2\pi) + 225) = cos(225^\circ)[/tex]
There is a trigonometric identity that:[tex]cos(\pi + \theta) = -cos(\theta)[/tex]
Thus:
[tex]cos(945^\circ) = cos(225^\circ) = cos(180^\circ + 45^\circ) = -cos(45^\circ) = -\dfrac{1}{\sqrt{2}}\\ cos(945^\circ) = -\dfrac{1}{\sqrt{2}}[/tex]
Note that wherever i have used [tex]\pi[/tex], it refers to [tex]\pi ^ \circ[/tex] (in degrees).
Thus, the value of cos(945°) is given by:

Answers
Answer:
The probability is 0.04746
Step-by-step explanation:
Firstly, we calculate the z-score here
Mathematically;
z-score = x-mean/SD/√n
Where from the question;
x = 85, mean = 90 , SD = 15 and n = 25
Plugging these values into the equation, we have;
Z = (85-90)/15/√25 = -5/15/5 = -1.67
So the probability we want to calculate is ;
P(z > -1.67)
We use the standard normal distribution table for this;
P(z > -1.67) = 0.04746

Midpoint point formula says that if there are two points (x1,y1) and (x2,y2) then
coordinate of midpoint is given by
midpoint (x1+x2)/2 , (y1+y2)/2
_______________________________________________
In the problem, we have to find the center of circle of by using the midpoint formula.
Since the circle is circumscribed in square. Its center will be midpoint of either of the diagonal.
To find the center we can take coordinate of any of two diagonal points of square and find midpoint for this and that will be center of circle.
_________________________________________________
1st diagonal pair(4,8) and (-8,-3)
Then midpoint is (4 + -8)/2 , (8+ -3)/2
midpoint (-2, -2.5)
Thus, center of circle is (-2,-2.5)
we can verify this by using other diagonal pair (-8,8) and (4,-3)
Midpoint in this case can be calculated as
midpoint (-8+4)/2 , (8 + -3)/2
midpoint (-2,-2.5)
Thus, we see that in both cases Midpoint is same and hence center is (-2, -2.5)

What is the solution to this equation? w - 3 = 15
Answers
Answer:
w = 18Step-by-step explanation:
w - 3 = 15
Add 3 to both sides to make w stand alone
That's
w - 3 + 3 = 15 + 3
w = 15 + 3
We have the final answer as
w = 18
Hope this helps you
Answer: w = 18
Step-by-step explanation: To solve for w in this equation, we want to get w by itself on the left side of the equation.
Since 3 is being subtracted from w, to get w by itself,
we need to add 3 to the left side of the equation.
If we add 3 to the left side, we must also add 3 to the right side.
Notice that on the left side, -3 and +3 cancel
each other out so were simply left with w.
On the right side, 15 + 3 is 18.
So we have w = 18.
Gabrielle's age is three times Mikhail's age. The sum of their ages is 92. What is Mikhail's age?
Answers
Answer:
Gabrielle is 69 while Mikhail is 23.
Step-by-step explanation:
Let G represent Gabrielle's age and M represent Mikhail's age.
Gabrielle is three times Mikhail's age. In other words:
[tex]G=3M[/tex]
The sum of their ages is 92. In other words:
[tex]G+M=92[/tex]
This is a system of equations. Solve. Substitute in G:
[tex]G+M=92\\(3M)+M=92\\4M=92\\M=23[/tex]
Thus, Mikhail is 23. Now, find Gabrielle's age:
[tex]G=3M\\G=3(23)\\G=69[/tex]
Gabrielle is 69.

Answer:
Pii is equAAAaaaaallLLLL to 3.14(rounded)
Step-by-step explanation:
Here listed are some formulas which can help you with your problems:
circumference of a circle=C=2πr
however, you can also write it as dπ, since is two d times r.
area of a circle= πr^2
simply plug in your values, and solve them
you have all the materials you need to know
Further assistance/spoonfeed time:
We know the formulas for the circumference and area.
We also have the values of the circles A and B.
C=2πr
That's the formula, and now I'm gonna plug in the values given to me for A, which is 21.98 for circumference, and 7 for diameter.
(21.98)=2πr
Like I said before, the radius multiplied by 2 is the diameter, which is 7. But if you actually want the radius for some reason, just divide the diameter by 2.
let's update the equation: 21.98= 7π
now divide both sides by seven, and you'll get 3.14=π
area=π^2
now do what i just did, according to this formula
