The length of one side of the region containing the small squares is 64 inches.
Let x be the length of one side of the region containing the small squares.
The area of the small squares is 64 * 1 = 64 square inches.
The area of the border is (x + 2)^2 - x^2 = 4x + 4 square inches.
Since the area of the small squares and the border is equal to the area of the chessboard, we have:
64 + 4x + 4 = 324
68 + 4x = 324
4x = 256
x = 64
Therefore, the length of one side of the region containing the small squares is 64 inches.

What is Triangle?
A triangle is a three sided polygon, which has three vertices and with three angles.
Since, The sum of all three angle in a triangle will be 180 degree.
Now, For option A;
The angles are 40° , 50°, 60°.
Sum of angles = 40° + 50° + 60°
= 150°
Hence, These set are not possible.
For option B;
The angles are 50° , 60°, 70°.
Sum of angles = 50° + 60° + 70°
= 180°
Hence, These set are possible.

Which numbers are 3 units from −6 on this number line?
Drag and drop all of the numbers that are 3 units from −6 to their correct position on the number line.
-9 and -3 are both 3 units from -6 on the number line.
Answer: -9 and -3 are numbers which are 3 units from -6 on the number line.
Step-by-step explanation:
Since we have given that
3 units from -6 on the number line.
As we know that
there is right hand side and left hand side on the number line.
Left hand side is for negative numbers, and right hand side is for positive numbers.
So, the number which is 3 units from -6 on the left is given by
[tex]-6-3=-9\ units[/tex]
The number which is 3 units from -6 on the right is given by
[tex]-6+3=-3\ units[/tex]

Select the table of values where the quadratic function changes direction at a different value of x than the others.
Imagine that this is a graph.
A.
x -3 -2 -1 0 1 2 3
y 2 3 2 -1 -6 -13 -22
B.
x -3 -2 -1 0 1 2 3
y 2 3 2 -1 -6 -13 -22
C.
x -3 -2 -1 0 1 2 3
y 4 3 4 7 12 19 28
D.
x -3 -2 -1 0 1 2 3
y 1 -1 1 7 17 31 49
Answer:
x -3 -2 -1 0 1 2 3
y 28 19 12 7 4 3 4
Step-by-step explanation:
The point where the quadratic function changes direction (which is the maximum or the minimum of the function) is called the turning point. In options A, B and C the turning point is at (-2, 3), and in option D the turning point is at (-2, -1).
Given that all of them correspond to the same x-value and options A and B are the same, I assume one of them was mistyped. Given the following option:
x -3 -2 -1 0 1 2 3
y 28 19 12 7 4 3 4
we see that the turning point is at (2, 3) which represents a different x-value.
Point A is located at (-5, 2) and is reflected in the y-axis. What are the coordinates of point A'?
A.(-5, -2)
B.(5, 2)
C.(5, -2)
When a point is reflected across the Y axis, the Y coordinate remains the same and the X coordinate becomes the opposite of the original value.
Points are written as ( X,Y)
The original point is (-5,2)
The opposite x value would be 5 and the Y value stays the same.
The reflected point would be (5,2)
The answer is B.
A.(-5, -2). The reflected point A' after reflecting point A with coordinates (-5, 2) in the y-axis will have coordinates (5, 2).
Explanation:When point A, which is located at (-5, 2), is reflected in the y-axis, you have to switch the sign of the x-coordinate while keeping the y-coordinate the same. This is because reflection across the y-axis means that the point's position will be mirrored over the y-axis, resulting in the same vertical (y) positioning but an opposite horizontal (x) positioning. Therefore, the reflected point A', will be at (5, 2), which corresponds to answer B.
A path starts and ends at the same vertex.

Select all of the angles that have a positive measure
Answer: angle 2, 5, and 6
Step-by-step explanation:
edge 2023
In mathematics, angles have a positive measure when they are measured counterclockwise from the reference line or origin.
Explanation:In mathematics, angles can be measured in positive or negative degrees or radians. An angle is considered to have a positive measure if it is measured in the counterclockwise direction. Therefore, any angle that is measured counterclockwise from the reference line or origin is considered to have a positive measure.
For example, if we have a line segment and we measure an angle of 60 degrees counterclockwise from the positive x-axis, the angle has a positive measure. Similarly, if we measure an angle of 45 degrees counterclockwise from the positive y-axis, the angle also has a positive measure.

1) PEMDAS: 12 * 5 + 6 / 6
12 * 5 = 60
60 + 6 / 6
6 / 6 = 1
60 + 1 = 61
61 is the final answer.
2) Absolute Value: |-2 - 4| = -6 HOWEVER, because it is in the absolute value signs, it becomes 6. 6 - 4 = 2
2 in the final answer.
3) 4 + 4 + 2 = 10 Because they are all negatives, we add back the negative sign.
-10 is the final answer.
4) 15x + 1 = 26
Subtract 1 from each side.

2x + 3x = 5x
5x - 4 = -1
Add 4 to each side
5x = 3
3/5 = 0.6
x = 0.6
6) x-2/3 = x+4/5

Explain the difference between a markup and a margin.
Answer:
Step-by-step explanation: mark up would be a fixed percentage, say you mark up your goods 50% your cost is $1 and 50% m-up would mean a selling price of 1.50. given this , your margin is 50cents. but margin may vary, there are indirect costs, example. store a charges, 1% display fee, store b charges 3% display fee. so, in store by your margin decreases. other factor that may affect margin are commission, local taxes, store charges.
Answer:
The answer is
Profit margin is sales minus the cost of goods sold. Markup is the percentage amount by which the cost of a product is increased to arrive at the selling price. Markup is the retail price for a product minus its cost, but the margin percentage is calculated differently.

which equation could be used to create the graph?
Answers
A y=x -2
B y=x -4
C y= x/3
D y=3x
Answer:
C
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (9, 3) ← 2 points on the line
m = [tex]\frac{3-0}{9-0}[/tex] = [tex]\frac{3}{9}[/tex] = [tex]\frac{1}{3}[/tex], thus
y = [tex]\frac{1}{3}[/tex] x
Or
y = [tex]\frac{x}{3}[/tex] → C
Answer:
C
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (9, 3) ← 2 points on the line
m = \frac{3-0}{9-0} = \frac{3}{9} = \frac{1}{3}, thus
y = \frac{1}{3} x
Or
y = \frac{x}{3} → C

Ripley told his mom that multiplying whole numbers by multiples of 10 was easy because you just count zeros in the factors and put them in the product. He used these two examples to explain his strategy.
7,000 × 600 = 4,200,000
(3 zeros) (2 zeros) (5 zeros)
800 × 700 = 560,000
(2 zeros) (2 zeros) (4 zeros)
Ripley’s mom said his strategy will not always work. Why not? Give an example.
Answer:
She is right, it won´t always work.
Step-by-step explanation:
Hi, in the examples this tactic works because the first numbers, when multiplied, don´t equal 10 (7x6=42 and 8x7=56). If you multiply both numbers and give you 10, you will have to add another zero to the final number and the trick would crash.
Example:
200 x 500 = 100,000
(2 Zeros) (2 zeros) (5 zeros)

Shaunee won 79 tickets at Chuck e' Cheese's. She
kept 25 of them, and split the rest evenly between 3
friends. How many did each friend get?
Answer:
Step-by-step explanation:
From the problem statement, we can set up the following equation:
[tex]3N + S = 79[/tex]
where [tex]N[/tex] is the number of tickets each friend got, and [tex]S[/tex] is the number of tickets that Shaunee got. We know that Shaunee got 25, so we know [tex]S = 25[/tex] and can plug that into the equation:
[tex]3N + 25 = 79[/tex]
Subtracting 25 from each side gives us the following:
[tex]3N = 54[/tex]
Dividing both sides by 3 gives us the answer:
[tex]N = 18[/tex]
79 tickets minus 25 is 54
Shawnee has 54 tickets to split between her friends.
54 divided by 3 friends equals 18 tickets.
You can check the answer by multiplying: 18x3 equals 54.
Hence, her friends each got 18 tickets...
