Find the area of the shaded region formed by circle that touches the edges of a rectangle.
Answer:
[tex] 266.14 \: {cm}^{2} [/tex]
Step-by-step explanation:
In case of rectangle:
Length l = 30 cm
Width w = 14 cm
Since, circle touches the edges (lengths) of the rectangle.
Therefore,
Diameter of circle = 14 cm
So, radius r = 14/2 = 7 cm
Area of the shaded region = Area of rectangle - Area of circle
[tex] = lw - \pi {r}^{2} \\ \\ = 30 \times 14 - 3.14 {(7)}^{2} \\ \\ = 420 - 3.14 \times 49 \\ \\ = 420 - 153.86 \\ \\ = 266.14 \: {cm}^{2} [/tex]

a land area was divided among three heirs in the ratio 5:2:4 . if the largest share was 20 hectares of the land .what is the total area of the land
with solution please and what type of proportion thank you very much
Answer:
44 hectares
Step-by-step explanation:
The largest number in the ratio is 5 and corresponds to the largest share.
The largest share is 20 hectares.
20/5 = 4
Multiply each number in the ratio by 4 to get the number of hectares of that portion.
5 * 4 = 20
2 * 4 = 8
4 * 4 = 16
20 + 8 + 16 = 44
Answer: 44 hectares
If you need to show a proportion, then do it this way.
The ratio is 5:2:4
Add 5 + 2 + 4 = 11
The ratio of the largest portion to the total area is
5/11
The largest portion is 20 hectares, and the total area is unknown, so we use x. The ratio of the largest portion to the total area is
20/x
We set the two ratios equal creating a proportion.
5/11 = 20/x
Cross multiply
5x = 11 * 20
Divide both sides by 5
x = 11 * 4
x = 44
Answer: 44 hectares

A diagram of a rectangular pool with the diagonal of 50 meters is shown below. Connected to the pool is a square shaped kid’s pool.
What is the area of the kid’s pool in the diagram?
Answer:
The area of the kids' pool is 900 square meters.
Step-by-step explanation:
The area of the kids' pool is 900 square meters. Only one side length needed to be found because it is a square (all sides are the same). The side length that can be easily found is the one that is shared with the rectangular pool. Using the Pythagorean theorem (a²+b²=c²), that missing side can be calculated. 40² is 1600 and 50² is 2500. To get the missing side ("b"), "c" must be subtracted by "a". 2500-1600=900. Even though that is the answer, the work is not done. The square root of 900 is 30. In the end, the missing side ("b") is 30 square meters. To find the area, you have to multiply 30 by 30. 30 times 30 is 900. So the kids' pool is 900 square meters.

Answer:
Step-by-step explanation:
[tex]\frac{3x + 5}{4x +2}=\frac{3x+4}{4x + 7}[/tex]
Cross multiply,
(3x+ 5 ) (4x + 7)=(3x + 4)*(4x + 2)
3x*4x + 3x *7 + 5*4x + 5*7 = 3x*4x + 3x*2 +4*4x + 4*2
12x² + 21x + 20x + 35 = 12x² + 6x + 16x + 8 {Combine like terms}
12x² + 41x + 35 = 12x² + 22x + 8
12x² + 41x +35 - 12x² - 22x = 8
12x² - 12x² + 41x - 22x + 35 = 8
0 + 19x + 35 = 8
19x = 8 - 35
19x = -27
x = -27/19
The green triangle is a dilation of the red triangle with a scale factor of s=13 and the center of dilation is at the point (4,2)
What are the coordinates of Point C'? C'(___,____)
What are the coordinates of Point A? A(____,_____)
Answers:
C ' (2, 5)A (16, 8)================================================================
Explanation:
I'm assuming you mean to say "scale factor of s = 1/3" since the green triangle is smaller than the red triangle.
Let's start at the point (4,2). This is the center of dilation. This fixed point does not move or change as you apply any dilation (as long as you keep this as the center of course). Every other point will move. For instance, the point (10,14) moves to (6,6) after applying the dilation.
----------------------
The x coordinate of the center point (4,2) is x = 4.
The x coordinate of the point (10,14) is x = 10.
Going from (4,2) to (10,14) will have us move a horizontal distance of 10-4 = 6 units.
Take 1/3 of this horizontal distance and we get (1/3)*6 = 2. This means that if we started at the center point (4,2) and move 2 units to the right, we will have the x coordinate to be x = 4+2 = 6, which matches up with the x coordinate of the point (6,6)
-------------------------
We'll do the same sort of thing with the y coordinates
The point (4,2) has the y coordinate y = 2
The point (10,14) has the y coordinate y = 14
The vertical distance between those points is 14-2 = 12 units
One third of this is (1/3)*12 = 4
If we started at (4,2) and moved up 4 units, then the y coordinate goes from y = 2 to y = 2+4 = 6. This also matches (6,6)
----------------------------
Hopefully by now you have a sense of how this all works. Let's use these tricks to find the location of point A.
The horizontal distance from (4,2) to (8,4) is 8-4 = 4 units. This triples to 4*3 = 12 units. We triple here because we're going in reverse of the process described in the previous two sections. If (8,4) and A swapped places, then we would take one third instead.
We'll use that 12 to count out 12 horizontal spaces from (4,2) to get to (16,2). I added 12 to the x coordinate of (4,2).
Repeat the process for the y values. The vertical distance from (4,2) to (8,4) is 2 units, which triples to 6. Add 6 onto the y coordinate of (16,2) and we arrive at (16, 8) which is the location of point A.
--------------------------------
Now let's find the location of point C'
The horizontal distance from (-2,11) to (4,2) is 6 units because |-2-4| = 6. Multiply this by 1/3 and we get (1/3)*6 = 2
To get to the location point C', we need to start at (4,2) and move to the left 2 units. That means (4,2) will move to (2,2) as a temporary location.
We apply the same idea for the y coordinates. The vertical distance from (4,2) to (-2,11) is 9 units. This leads to (1/3)*9 = 3 units being the vertical distance from (4,2) to the location of C'. We'll add 3 to the y coordinate of (2,2) to arrive at (2,5) which is the location of C'.
