An online furniture store sells chairs for $150 each and tables for $650 each. Every day, the store can ship at most 16 pieces of furniture and must sell no less than $3900 worth of chairs and tables. If x represents the number of tables sold and y represents the number of chairs sold, write and solve a system of inequalities graphically and determine one possible solution.
Answers
Using graphical method to solve the system of linear inequalities, the solution are (x, y) 3, 13.
System of Linear InequalitiesA system of linear inequalities in two variables consists of at least two linear inequalities in the same variables. The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system.
To solve this, we can write out the equations as
x + y ≤ 16 ...eq(i)
650x + 150y ≥ 3900 ...eq(ii)
Solving both equations with a graph.

Answers
A sinusoidal function that matches the given graph is y=cosπx/3+2.
From the given question, the curve is the graph of a sinusoidal function.
It goes through the points (- 4, 0) and (2, 0).
We have to find the sinusoidal function that matches the given graph.
For this problem, we can use either of these general equations :
y = Asin(Bx + C) + D or y = Acos(Bx + C) + D.
A = amplitude = distance on Y-axis from centre of graph to highest or lowest point.
So from the given graph
A = 1
T = period = distance on X-axis over one complete cycle
So from the given graph
T = 6.
So B=2π/6 =π/3
D = distance that graph has been moved up or down on the Y-axis
D = 0
C= horizontal shift (left side if positive)
From the given Graph
C = 2
So, equtaion is
y = Acos(Bx + C) + D
Putting the each variable value
Using π =3.1416.
y = 1*cos(π/3 x + 2) + 0
y = cosπx/3 + 2
Hence, a sinusoidal function that matches the given graph is y=cosπx/3+2.

Given two circles on a coordinate plane, use transformations to prove that both circles are similar
Answers
The two circles are said to be similar because they undergo a rigid transformation that does not change its shape.
How to prove similarity using transformation?A similarity transformation is defined as one or more rigid transformations (reflection, rotation, translation) followed by a dilation. Now, when a figure is transformed using a similarity transformation, an image is created that is similar to the original figure. This means that, two figures are similar if a similarity transformation will map the first figure to the second figure.
By definition of similarity transformation, looking at the given diagram, both shapes are circles and as such it is obvious that one circle has been dilated by a scale factor to get the other circle.
Thus, they have the same shape and are similar circles.

Does it have 30 layers because 540 divided

Answers
Answer:
You are absolutely correct!
Step-by-step explanation:
To find the area of a cube, we do length (l), times width (w), times height (h).
Let's say that the length is 6, while the width is 3. That would make the first layer 18, like in your problem.
18 × 10 = 180
18 × 20 = 360
18 × 30 = 540
So, yes! You are correct!
As each layer can hold 18 balls 540 balls can be placed in 30 layers.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, A box holds 540 balls, and each layer holds 18 balls.

Answers
We were told that Wesley willed his estate to Margaret, Betty Jo, and Johnny.
Given that he gave Margaret $20,000. Betty Jo got 22 times as much as Margaret, it means that the amount the at Betty Jo got is 22 * 20000 = 440000
Given that Johnny got 32 times as much as Margaret, it means that the amount that Johnny got is
20000 * 32 = 640000
Therefore, the total value of the estate is
20000 + 440000 + 640000 = 1100000
The total value of the estate is $1,100000

The ratio of the length of a tile in the model to the length of an actual tile is?
Answers
The ratio of the length of an actual tile is 4/3, and the ratio of area is 16/9.
What is ratio?
A ratio is a comparison of two or more numbers that indicates their sizes in relation to each other. A ratio compares two quantities by division, with the dividend or number being divided termed the antecedent and the divisor or number that is dividing termed the consequent.
Given,
the length of tile is 2/3 and width = 1/2
The length of actual tile is 1/2 and width = 3/8
Therefore, the ratio of the actual length of tile = 2/3 ÷ 1/2
=2/3×2/1
=4/3
The area of the tile in the model to the area of tile in actual tile = 2/3×1/2÷(1/2×3/8)
=1/3÷3/16

Alright! So! We're trying to figure out the slope of the table. And how do we do that? Well, there is actually a formula that can help us here! And that is using the slope between two points.
What is the formula for the slope between two points?The formula is as follows:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
It allows us to figure out the slope by taking two coordinate points and sub them into the formula to find m, which in this case is the slope!
Let's use this equation twice, we do this to make sure that the slope is consistent throughout the table.
Using the formula for the first two points:The first two points are:
(3, 36)(6, 30)Now, we apply the formula as such:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{30-36}{6-3}[/tex]
[tex]m=\frac{-6}{3}[/tex]
[tex]m=-2[/tex]
Alright, so we have a slope [tex]m=-2[/tex] for the first two points! Let's check if the last two points have the exact same slope as well!
Using the formula for the last two points:The last two points are:
(9, 24)(12, 18)We apply the formula again!
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{18-24}{12-9}[/tex]
[tex]m=\frac{-6}{3}[/tex]
[tex]m=-2[/tex]
Conclusion:Well, what do you know? Given our application of the slope between two points, we get a common answer [tex]m=-2[/tex]. So, therefore, it would be b) [tex]m=-2[/tex]
