A middle class family with two working parent receives $100,000 annually. About 40% is withheld (taken out of their paycheck for income tax and retirement plan). What is this family monthly income after the 40% is taken off?
Answer:
$60,000
Step-by-step explanation:
100,000 / 10 = 10,000, 10- 4=6, 10,000 * 6 = 60,000
To determine the monthly income of a family after 40% is withheld from a $100,000 annual income, subtract the amount withheld ($40,000) from the annual income and divide by 12, yielding a monthly income of $5,000.
To calculate the monthly income after taxes for the family, we first need to determine the amount withheld from the annual income for taxes and retirement plans. With an annual income of $100,000 and 40% being withheld, we do the following calculation:
Amount withheld: $100,000 times 0.40 = $40,000After-tax annual income: $100,000 - $40,000 = $60,000Monthly income after tax: $60,000 / 12 months = $5,000Therefore, the family's monthly income after the 40% is taken off would be $5,000.

In the graph of an inequality, the region below a dashed line through the points (4, 3) and (0, 2) is shaded. What inequality does the graph represent?
Answer:
The inequality that represents the graph is y < [tex]\frac{1}{4}[/tex]x + 2
Step-by-step explanation:
i) the region below a dashed line through the points (4,3) and (0,2) is shaded.
ii) first we find the equation of the line passing through the points (4,3) and (0,2)
(y - 3) = [tex](\frac{3 - 2}{4 - 0})[/tex](x - 4) ⇒ y - 3 = [tex]\frac{1}{4}[/tex](x - 4)
⇒ 4y - 12 = x - 4 ⇒ 4y = x + 8 ⇒ y = [tex]\frac{1}{4}[/tex]x + 2
iii) for the area shaded below the line whose equation is given in ii) above the inequality that will represent the shaded region is given by
y < [tex]\frac{1}{4}[/tex]x + 2
The graph represents the inequality y < 1/4x + 2. The inequality was calculated based on the information given: points the line goes through, shading below the line, and the line being dashed all determine the inequality's form.
Explanation:To determine the inequality graphed, we first need to find the equation of the line. The line passes through the points (4, 3) and (0, 2), so we can use these points to find the slope of the line.
The formula for the slope (m) is [tex](y2 - y1)/(x2 - x1).[/tex]. Plug in the coordinates of the two points into this formula: ([tex]3 - 2) / (4 - 0) = 1/4[/tex] So, our slope is 1/4.
Given a slope (m) of 1/4 and the y-intercept (b) of 2, we can write the equation of the line in slope-intercept form (y = mx + b) as y = 1/4x + 2.
One key part of your question is that the region below this line is shaded. In the language of inequalities, shading below the line corresponds to 'y is less than' the line's equation. Also, the line is dashed, meaning that the points on the line are not included in the solution, which we denote as 'less than' rather than 'less than or equal to'.
So, the inequality represented by this graph is y < 1/4x + 2.

What is the answer of (1, 9); slope 4 on a graph?
The point (1, 9) with a slope of 4 on a graph corresponds to the answer of 13.
Explanation:The answer is 13.
To calculate this, we use the formula for the equation of a straight line: y = mx + b, where m is the slope and b is the y-intercept. In this case, the equation would be y = 4x + 9. Substituting x = 1 into the equation gives y = 4(1) + 9 = 13.
Therefore, the point (1, 9) has a slope of 4 on the graph.

Mr Edwards buys 2 new knobs for each of his kitchen cabinets. How many knobs does he buy?
Answer:
Step-by-step explanation:
You need to find out how many cabinets it is
Final answer:
To determine how many knobs Mr. Edwards needs to buy for his kitchen cabinets, we need to know the total number of cabinets since he needs 2 knobs for each cabinet.
Explanation:
Mr. Edwards wants to buy new knobs for his kitchen cabinets. To determine how many knobs he needs to buy, we would need to know the exact number of kitchen cabinets he has. However, the information about Chelsea and her trip to Europe, her being a shop-a-holic and physics lover, and the estimation of the number of pairs of shoes that can fit in her closet seem to be unrelated to Mr. Edwards's question. Therefore, to answer Mr. Edwards's query, we need the number of cabinets to calculate the total number of knobs. If there are X cabinets, Mr. Edwards would need to purchase 2X knobs.

This figure is made up of a rectangle and parallelogram.
What is the area of this figure?
Enter your answer in the box. Do not round any side lengths.
The area of the figure is 40 units. (rounded off from 39.998 units)
Step-by-step explanation:
1. Area of the figure = Area of Rectangle + Area of Parallelogram.
2. Naming points:
Let the rectangle consist of points A(-6,-1), B(-5,-5), C(3,-3) and D(2,1).
Let the parallelogram consist of points C(3,-3), D(2,1), E(2,7) and F(3,3).
3. Each coordinate has a point on the x-axis and a point on the y-axis. We shall refer to these points as x', x'' ,x''' and so on corresponding to the x-axis values of A, B, C and so on in that order till F. For the y-axis points, we will name them in the series of y', y'', y''' and so on.
In simple words, in A(-6,1), x' = -6; y' = -1
4. Formula for finding area:
Area of a rectangle = length (l) × width (w)
Area of a parallelogram = base (b) x height (h)
5. Finding area of the rectangle:
l = AD = [tex]\sqrt{[x'''' - x']^{2} - [y'''' - y']^{2}}[/tex]
, i.e. AD = [tex]\sqrt{[2 - (-6)]^{2} - [1 - (-1)]^{2}}[/tex]
, i.e. AD = √68 = 8.246 (rounded to 3 decimals) = l
Now, w = AB = [tex]\sqrt{[x'' - x']^{2} - [y'' - y']^{2}}[/tex]
, i.e. AB = [tex]\sqrt{[(-5) - (-6)]^{2} - [(-5) - (-1)]^{2}}[/tex]
, i.e. AB = √17 = 4.123 (rounded to 3 decimals) = w
Area of rectangle = l x w = 8.246 x 4.123 = 33.998 units.
6. Finding area of the parallelogram:
b = DE = 6 units (we can observe this from the graph, i.e. points from 1 to 7 on the y axis)
h = Height is the line drawn perpendicular to the base from point F, which as we can see is 1 unit long.
Hence, Area of parallelogram = b x h = 6 x 1 = 6 units.
7. Now, adding both, we can arrive at the final answer.
Area of the figure = Area of rectangle + Area of parallelogram,
i.e. 33.998 units + 6 units = 39.998 units. (can be rounded off to 40 units)

The graph which shows the pre-image of quadrilateral ABCD and the image A’ B’ C’ D’ after the rotation is graph number 1.
What is rotation of figure?Rotation of a figure is the transformation of it about a point in either clockwise or anticlockwise direction.By rotating, a figure changes the point of the figure.
The quadrilateral ABCD and point E in the graphed in the figure below. This quadrilteral is rotated r(135°, E) in order to construct quadrilteral A’ B’ C’ D’ .
The rotation of the figure is 135 degrees. This angle can be break as,
[tex]\theta=135\\\theta=90+45[/tex]
The angle is rotated 90 and 45 degrees. To rotate 90 degree, the angle must be flliped 90 degree clockwise from point E keeping the point c at center.
After this the 45 degree more the figure is rotated. This is shown accurately in the figure A.
Thus, the graph which shows the pre-image of quadrilateral ABCD and the image A’ B’ C’ D’ after the rotation is graph number 1.

D. GH≅MN
E. m∠H≅m∠N
In similar triangles ΔFGH and ΔLMN, only the corresponding angles are congruent (thus ∠H ≅ ∠N). The sides are proportionate, not necessarily congruent. Other listed options are either incorrect or unclear due to potential misinterpretations or typographical errors.
Explanation:Given that triangles ΔFGH and ΔLMN are similar (ΔFGH ~ ΔLMN), the following must be true based on the concept of similar triangles:
The corresponding angles are congruent, which means that ∠F ≅ ∠L, ∠G ≅ ∠M, and ∠H ≅ ∠N (option E). The corresponding sides are proportionate, meaning that the ratio of corresponding sides (FG/LM, GH/MN, and FH/LN) are equal. However, this doesn't mean that the corresponding sides are congruent. Hence option D is not necessarily true. Option B implies that lines FH and LN are similar, which is not a concept in geometry. Hence it's incorrect. Option A is incorrect because it seems to imply congruence of some unspecified aspect of the triangles, which is not a guaranteed condition under triangle similarity. Option C's meaning is unclear due to potential typographical error or misinterpretation.Learn more about Similar Triangles here:

A bag of Chocolates is labeled to contain 0.384 pounds of chocolate the actual weight of the chocolate is 0.3798 pounds. How much have you or lighter are the chocolates and The started on the label. Show your reasoning
Answer:
The actual weight is 1.1% less (100 - 98.9) than the labeled weight.
Step-by-step explanation:
1. Let's review the information given to us to answer the question properly:
Labeled weight of the bag of chocolates = 0.384 pounds
Actual weight of the bag of chocolates = 0.3798 pounds
2. How much have you or lighter are the chocolates and the stated on the label. Show your reasoning.
Let's find how much we have comparing the labeled weight and the actual weight, using a Direct Rule of Three, this way:
Weight Percentage
0.384 100 %
0.3798 x %
0.384x = 0.3798 * 100
0.384x = 37.98
x = 37.98/0.384
x = 98.9 (Rounding to one decimal place)
The actual weight is 1.1% less (100 - 98.9) than the labeled weight.
The chocolates are 0.0042 pounds lighter than what is stated on the label.
Explanation:The difference in weight between the labeled weight and the actual weight of the chocolates is 0.0042 pounds. This means that the chocolates are 0.0042 pounds lighter than the label indicates.
To calculate this, subtract the actual weight from the labeled weight: 0.384 - 0.3798 = 0.0042 pounds.
So, the chocolates are 0.0042 pounds lighter than what is stated on the label.
