Triangle JKL has vertex coordinates J(0,-3), K(-1,0), and L(-2,-1). It is reflected across the line y = x. What are the coordinates of J’K’L?
A. J’(0,-3), K’(1,0), L’(2,-1)
B. J’(-3,0), K’(0,-1), L’(-1,-2)
C. J’(3,0), K’(0,1), L’(1,-2)
D. J’(0,3), K’(-1,0), L’(-2,1)
Answers
Answer:
B
Step-by-step explanation:
Under a reflection in the line y = x
a point (x, y ) → (y, x ), thus
J(0, - 3 ) → J'(- 3, 0 )
K(- 1, 0 ) → K'(0, - 1 )
L(- 2, - 1 ) → L'(- 1, - 2 )

A composite figure has a radius of 10 cm.
A circle with radius of 10 centimeters. One-quarter of the circle is cut out of the figure.
What is the area of this composite figure? Use 3.14 for Pi.
23.55 centimeters squared
78.5 centimeters squared
235.5 centimeters squared
314 centimeters squared
Answers
Answer:
C, 235.5 cm^2
Step-by-step explanation:
Formula for area of circle:
A = πr^2
Where π represents pi(3.14 or 22/7) and r represents the radius.
Plug in given value (10):
A = πr^2
A = 3.14(10)^2
A = 3.14(100)
A = 314
Now they say a quarter of this circle is cut out, which means we have to first find out what a quarter of this area is:
314/4
= 78.5
A quarter of this circle is 78.5, so let's subtract this from the total area (314):
314 - 78.5
= 235.5 cm^2
The area is 235.5 centimeters squared.

Error Analysis: A store is instructed by corporate headquarters to put a markup of 67% on all items. An item costing $6 is displayed by the store manager at a selling price of $4. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Part 1: The correct selling price is (Round to the nearest dollar as needed.)
Part 2: What was the manager's likely error?
A. The manager set the selling price at the markup.
B. The manager subtracted the markup from the cost instead of adding it.
C. The manager set the selling price at the cost.
D. The manager added the markup to the cost instead of subtracting it.
Answers
Answer:
To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.
Therefore, the correct selling price is $4.
The manager's likely error was that they set the selling price at the cost (option C).
Step-by-step explanation:
The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Cost of item = $6
Markup = 67%
67% of $6 ⇒ 0.67 x 6 = $4.02
Add the markup in the cost = $6 + $4.02 = $10.02
Round to nearest dollars = $10.2 ≈ $10.
The manager put $4 which is a markup instant of the selling price of $10.
Hence "The correct selling price is $10 and the manager set the selling price at the markup".

What is the value of x in this triangle?
Enter your answer in the box.
x =
Answers
Answer:
x = 47
Step-by-step explanation:
We need to solve for the interior angle measure x. To get x, we know that the sum of the triangles angle measures are 180, so lets write an equation to find x.
\(x+102+31=180\)
Add like terms
\(x+133=180\)
Subtract 133 on both sides
\(x=47\)
To check our work, we can add the angle measures together so we know we got it right.
\(47+102+31=180\)
Answer:
x=48
Step-by-step explanation:
add 102 and 31 then subtract it by 180

Answer:
x=−6/5Step-by-step explanation:
\(\frac{x}{3} - 2 + \frac{x}{2} + 6 = 3\\\)
Simplify both sides of the equation:\(\frac{x}{3} - 2 + \frac{x}{2} + 6 = 3\)
\(\frac{1}{3} x + -2 + \frac{1}{2} x + 6 = 3\)
\(( 1/3x + 1/2x ) + ( −2+6 ) = 3\) (Combine Like Terms)\(5/6 x + 4 = 3\)
Subtract 4 from both sides:\(5/6x + 4−4= 3−4\)
\(5/6x = −1\)
Multiply both sides by 6/5:\((6/5) * (5/6x) = (6/5) * (−1)\)
\(x=−6/5\)

Exactly 2 triangles are possible.

Answers
No triangle is possible. The sum of the interior angles of a triangle must be 180°. However, the sum of the given angles is 100° + 10° + 90° = 200°, which is greater than 180°. Therefore, no triangle can be drawn with these angle measures.
A gem store in Fort Lauderdale received a shipment of 1 1/2 pounds of moonstone crystals if these moonstones crystals if these moonstone crystals were separated into 6 equal bags how much would each bag weigh?
Answers
A shipment of 1.5 pounds of moonstone crystals was divided into 6 equal bags. Each bag would weigh 0.25 pounds, which is the same as 4.0 pounds.
How to solveTo solve this problem, we can use the following equation:
total weight / number of bags = weight of each bag
In this case, the total weight is 1.5 pounds and the number of bags is 6. So, the weight of each bag is:
1.5 pounds / 6 bags = 0.25 pounds per bag
Since 0.25 pounds is the same as 4.0 pounds, each bag would weigh 4.0 pounds.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
