Answer:
the difference of 2 or 3 rectangles
Step-by-step explanation:
In every case, the "shaded" area can be computed by finding the area of a "bounding" rectangle, and subtracting the areas of the rectangular cutouts that give the figure its shape.
(a) The cutout is the white space at upper right. (Insufficient dimensions are given.)
(b) The cutout is the white space at lower left. The bounding rectangle is 8×7, and the cutout is 4×3.
(c) The cutout is the rectangle in the middle. The bounding rectangle is 13×7, and the cutout is 4×1.
(d) The cutouts are the rectangles on either side. They could be considered as a single unit. The bounding rectangle is 20×25; the cutouts have a total width of 16 and a height of 20, so total 16×20.
(e) Similar to (d), the cutouts are the white spaces on either side. The bounding rectangle is 14×12. The cutouts total 12 in width and 3 in height, so total 12×3.
__
You will note in (d) and (e) that the dimensions of the cutouts have something in common with the dimensions of the bounding rectangle. This means the problem can be simplified a little bit by factoring out that common factor. In (e), for example, 14×12 -(12×3) = 12(14 -3) = 12×11

Write the standard form of the equation of the circle with center (−7,1) that passes through the point (−7,9).
Answers
Answer:
(x + 7)² + (y - 1)² = 64
Step-by-step explanation:
Use the equation of a circle, (x - h)² + (y - k)² = r²
Plug in the point and center, then solve for r:
(x - h)² + (y - k)² = r²
(-7 + 7)² + (9 - 1)² = r²
0 + 64 = r²
64 = r²
8 = r
Then, plug in the center and r² into the equation:
(x + 7)² + (y - 1)² = 64
So, (x + 7)² + (y - 1)² = 64 is the standard form of the circle's equation

A 12 foot board rests against the wall. The angle that the board makes with the ground is 60 degrees. How far is the base of the board from the wall?
Answers
Answer:
6 foot
Step-by-step explanation:
Since the board is 12foot and the angle makes 60 degrees to the wall, we can assume that it is the 30,60,90 degreees. 30,60,90 degrees triangle makes the side of x, 2x ,and xroot3.
Hence, the board(12foot) is equal to 2x.

EF = BC.
Paste a picture of your drawing in the answer box
Answers
The triangle ABC drawing, which has vertices at A (1,6), B (1,1), and C (5,1) is shown below.
A triangle is the most basic form for a polygon with three sides and three vertices. Triangles are divided into various groups using their sides and angles. The triangle's total angle is always equal to 180 degrees, which is an interesting triangle fact (straight angle).
It is common knowledge that a triangle is a type of polygon with three edges and three vertices.
A, B, and C are frequently used to denote its vertices, making it one of the most important shapes in geometry.
A (1,6), B (1,1), and C (5,1) will be picked as the points. 〖〖AB〗^2+ 〖BC〗^2= AC〗^2
Hence, the image of the triangle ABC's design, which has vertices at A (1,6), B (1,1), and C (5,1) is linked above.

a man buys eggs at RS 9.60 per dozen and sell 20 eggs for RS 18 what is his gain or loss percen?
Answers
Answer:
Percentage Gain = 12.5%
Step-by-step explanation:
Given
[tex]Cost\ Prize = 9.60[/tex] per dozen
[tex]Selling\ Price = 18[/tex] per 20
Required
Determine the percentage gain or loss
First, we have to calculate the unit cost price and the unit selling price.
If a dozen costs 9.60
Then 1 costs
[tex]Cost = 9.60/12[/tex]
[tex]Cost = 0.80[/tex]
If he sells 20 for 18
Then he sells 1 for:
[tex]Sell = 18/20[/tex]
[tex]Sell = 0.9[/tex]
The percentage change is then calculated as:
[tex]\%Change = \frac{Sell - Cost}{Cost} * 100\%[/tex]
[tex]\%Change = \frac{0.9 - 0.8}{0.8} * 100\%[/tex]
[tex]\%Change = \frac{0.1}{0.8} * 100\%[/tex]
[tex]\%Change = \frac{0.1 * 100\%}{0.8}[/tex]
[tex]\%Change = \frac{10\%}{0.8}[/tex]
[tex]\%Change = 12.5\%[/tex]
Because the percentage change is positive, then he made a gain.
Hence:
Percentage Gain = 12.5%

Find the equation of a line parallel to y = 12 that contains the point (3, 2).
Answers
Answer:
y = 2
Step-by-step explanation:
Let's first write the equation of y = 12 in slope-intercept form. Slope-intercept form is represented as:
y = mx + b
Where...
m: slope
b: y-intercept (the y-value at where the line intercepts the y-axis)
(x, y): any coordinate on the line
This line has a slope of 0 and a y-intercept of 12, therefore its equation is:
y = 0x + 12.
Parallel lines have the same slope. Therefore the equation of the parallel line can be represented as:
y = 0x + b
We need to find b, or the y-intercept.
Let's substitute the point given to us into the equation.
Solve for the y-intercepty = 0x + b
2 = 0(3) + b
2 = 0 + b
b = 2
Therefore the equation of a line parallel to y = 12 that contains the point (3, 2) is y = 2.
Which solution value satisfies the inequality x – 6 ≥ –7?
Question 18 options:
A)
x = –5
B)
x = 0
C)
x = –2
D)
x = –7
Answers
Answer:
B) x = 0
Step-by-step explanation:
To find the solution value that satisfies the inequality x – 6 ≥ –7, you must plug every x value into the x and see which one works.
Plug -5 into x
-5 – 6 ≥ –7
Combine like terms
-11 ≥ –7
This is false, -11 is not greater than or equal to -7.
Plug 0 into x
0 – 6 ≥ –7
Combine like terms
– 6 ≥ –7
This is true, -6 is greater than -7.
Plug -2 into x.
-2 – 6 ≥ –7
Combine like terms
-8 ≥ –7
This is false, -8 is not greater than or equal to -7.
Plug -7 into x.
-7 – 6 ≥ –7
Combine like terms
-13 ≥ –7
This is false, -13 is not greater than or equal to -7.
B) x = 0 is the only solution that is true and works, so that is your answer.

[tex]2ab^2-\frac{a^2b^2}{5}=\frac{10ab^2-a^2b^2}{5}[/tex]
Step-by-step explanation:
Given the expression
[tex]2ab^2-\frac{a^2b^2}{5}[/tex]
[tex]\mathrm{Convert\:element\:to\:fraction}:\quad \:2ab^2=\frac{2ab^25}{5}[/tex]
[tex]2ab^2-\frac{a^2b^2}{5}=\frac{2ab^2\cdot \:5}{5}-\frac{a^2b^2}{5}[/tex]
[tex]\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}[/tex]
[tex]=\frac{2ab^2\cdot \:5-a^2b^2}{5}[/tex]
[tex]=\frac{10ab^2-a^2b^2}{5}[/tex]
Thus,
[tex]2ab^2-\frac{a^2b^2}{5}=\frac{10ab^2-a^2b^2}{5}[/tex]
