Procedure
Gross Monthly Income: $66,000/12=$5,500
Monthly Federal Income Tax(18.7%)= $5,500*0.187=$1028.5
Monthly Social Security (FICA (6.2%) =$5,500*0.062=$341
Monthly Medicare (1.45%) =$5,500*0.0145=$79.75
Monthly State Tax (4%)= $5,500*0.04=$220
Monthly local Tax (0.1%)= $5,500*0.001=$5.5

The length of a side must be less than the sum of the other two sides. Here, that means x < 10+13, or x < 23.
In addition, remember that the length of a side must be greater than the difference of the other two sides. That means x > 13 - 10, or x > 3.
Therefore we have two limits for the value of x: 3 and 23.

SOLUTION:
Step 1:
Since the two figures are similar, it means that they have properties in common.
Step 2:
In the bigger figure, the side given is 10in and its area is 100 square inches meaning (10 in x 10 in).
Step 3:
In the smaller figure, the side given is 8in, and from step 1, we can see that the two figures are similar, so the area of the smaller figure will be (8 in x 8 in) = 64 square inches.

In the diagram,ABCD is a rectangular wall that casts a shadow CDEF, on the ground. The wall has a height of 4 feet. The shadow is a parallelogram that has a height, FG, that is twice the height of the wall. If the area of the wall is 29.2 square feet, find the area of the shadow.
Answers
We know that the height of the rectangular shape is BC=AD= 4 feet and the the area is A=29.2 ft^2. Since the area of our rectangle is given by
[tex]A=(DC)\times(BC)[/tex]we get
[tex]29.2=DC\times4[/tex]By moving the number 4 to the left hand side, we have
[tex]\begin{gathered} \frac{29.2}{4}=DC \\ \text{then} \\ DC=7.3 \end{gathered}[/tex]which also is the lenght of one side of our parallelogram.
Now, the area of our parallelogram is given by
[tex]A_P=\text{base}\times height[/tex]where the base is given by segment DC=7.3 ft and the height FG=2 BC. Then, we get
[tex]\begin{gathered} A_P=DC\times FG \\ A_P=DC\times2BC \end{gathered}[/tex]by substituting our previous result and BC=4 ft, we obtain
[tex]\begin{gathered} A_P=7.3\times2(4) \\ A_P=7.3\times8 \\ A_P=58.4ft^2 \end{gathered}[/tex]Then, the answer is 58.4 ft^2

Step-by-step explanation:
Area of a triangle = 1/2(b×h)
b or l = x+4
h = x
a = 40
1/2(x+4 × x) = 40
1/2(x+4 × x) = 40x + 4 × x / 2 = 40
4 × x = 4x
4x + x = 5x
5x/2 = 40
cross-multiply
40 × 2 = 5x
40 × 2 = 5x80 = 5x
divide both sides by 5
5x/5 = 80/5
5x/5 = 80/5x = 16

the image of the point (-9, 9)under a translation is (-5, 13). find the coordinates of the image of the point (-6, "-7)" under the same translation.
Answers
The coordinates of the image of the point (-6, -7) after translation is (-20,-3).
What are coordinates?a pair of figures used to specify a point's location on a coordinate plane using the horizontal and vertical separations from the two reference axes. They are typically expressed by the x-value and y-value pair (x,y). Always, the x-coordinate comes before the y-coordinate.
An ordered group of numbers known as coordinates is used to specify a point's location. In the event that the point is on a plane, two numbers are used.
The horizontal and vertical addresses of a point in any two-dimensional (2D) space, such as a sheet of paper or a computer display screen, are called the X and Y coordinates, respectively. These coordinates work as a pair to pinpoint a point's precise location.
A point located at (x,y), translated by (a,b) maps to the point (x+a,y+b).
If we know the location of the point (x,y) and the location of its image (x',y'), we can know the values of (a,b) by subtracting:
(a,b) = (x',y') - (x,y)
We know the coordinates of the point (9,9) and the coordinates of its image (-5,13). Calculate the translation:
(a,b) = (-5,13) - (9,9) = (-14,4)
If the point (-6,-7) is translated under the same conditions, then it will map to the point (-6,-7) + (-14,4) = (-20,-3).
The coordinates of the image are (-20,-3)

To graph the ellipse, connect (-2, -3), (6, 2), (14, -3), and (6, -8) with a smooth curve
How to graph an ellipse?The standard form of the equation of an ellipse with center (h, k) and major axis parallel to the x-axis is:
(x-h)²/a² + (y-k)²/b² = 1
When a>b
Major axis length = 2a
Coordinates of the vertices are (h±a, k)
Minor axis length is 2b
Coordinates of covertices are (h, k±b)
Coordinates of foci are (h±c, k). Also c²= a²-b²
Given: the equation (x-6)²/64 + (y+3)²/25 = 1
Comparing the given equation with (x-h)²/a² + (y-k)²/b² = 1:
h = 6, k = -3 => (h, k ) = (6, -3)
Thus, the center of the ellipse is (6, -3)
Coordinates of the vertices are (h±a, k)
Since a² = 64, a = √64 = 8
Thus, the endpoints of the major axis are 8 units from the center
(h±a, k) implies (h-a, k) or (h+a, k). Thus:
(h±a, k) = (6-8, -3) = (-2, -3) or (6+8, -3) = (14, -3)
Coordinates of covertices are (h, k±b)
Since b² = 25, a = √25 = 5
Thus, the endpoints of the minor axis are 5 units from the center
(h, k±b) implies (h, k-b) or (h, k+b). Thus:
(h, k±b) = (6, -3-5) = (6, -8) or (6, -3+5) = (6, 2)
Therefore:
The center of the ellipse is (6, -3). The endpoints of the major axis are 8 units from the center. The endpoints of the minor axis 5 are units from the center.
To graph the ellipse, connect (-2, -3), (6, 2), (14, -3), and (6, -8) with a smooth curve.
