Rotate shape A 180 about point (1,0)
The point after which shape A is rotated 180 degrees is (-1, 0).
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
Shape A is in the point (1, 0).
This means,
Shape A is in the First Quadrant.
Now,
Shape A is rotated 180 degrees.
If rotated clockwise or counterclockwise shape A will be in the same quadrant.
This means,
Shape A will be in the Third quadrant.
Now,
First quadrant coordinates = (x, y)
Third quadrant coordinates = (-x, -y)
So,
(x, y) → (-x, -y)
(1, 0) → (-1, 0)
Thus,
Shape A will be in (-2, 0).

[tex] \tt : \implies \dfrac{x+2}{x-2} + \dfrac{x-2}{x+2} = \dfrac{5}{6}[/tex]
[tex] \tt : \implies \dfrac{(x+2)(x+2) + (x-2)(x-2)}{(x-2)(x+2)} = \dfrac{5}{6}[/tex]
[tex] \tt : \implies \dfrac{(x+2)^{2} + (x-2)^{2}}{(x-2)(x+2)} = \dfrac{5}{6}[/tex]
Now, we know that :

[tex] \tt : \implies \dfrac{x^{2}+ 4 + \cancel{4x} + x^{2}+ 4 - \cancel{4x}}{x^{2}-4} = \dfrac{5}{6}[/tex]
[tex] \tt : \implies \dfrac{x^{2} + x^{2} + 4 + 4}{x^{2}-4} = \dfrac{5}{6}[/tex]
[tex] \tt : \implies \dfrac{2x^{2} + 8}{x^{2}-4} = \dfrac{5}{6}[/tex]
By cross multiply :

[tex] \tt : \implies 12x^{2} + 48 - 5x^{2} + 20 = 0[/tex]
[tex] \tt : \implies 7x^{2} + 68 = 0[/tex]
[tex] \tt : \implies 7x^{2} + 0x + 68 = 0[/tex]
Now, by comparing with ax² + bx + c = 0, we have :

[tex] \large \underline{\boxed{\bf{x = \dfrac{-b \pm \sqrt{b^{2} - 4ac}}{2a}}}}[/tex]
[tex] \tt : \implies x = \dfrac{-(0) \pm \sqrt{(0)^{2} - 4(7)(68)}}{2(7)}[/tex]

A chicken and rice recipe is shown below. Mrs. Hughes would like to make only two-thirds of the recipe. How many cups of each ingredient does Mrs. Hughes need? 2 2/3 cups of chicken broth 1 1/2 cups of chicken 3/4 cups of rice
Answer:
See explanation below
Step-by-step explanation:
This is actually pretty easy to explain, and we all need to do is work with fractions.
So we have a recipe for chicken and rice, but the person decides to use 2/3 of the recipe. to determine the quantity of each ingredient to be used, we just need to multiply the cups of each ingredient by 2/3, and that's it.
Let's go with each ingredient, one by one:
Chicken broth 2 2/3 cups:
In this case, let's convert the 2 2/3 to a simple fraction. (We just multiply the denominator by the single number and then, sum the numerator)
2 2/3 = (3*2) + 2 / 3 = 8/3 of cups
8/3 * 2/3 = 16/9 cups of chicken.
But to do this better, let's convert this into a mix fraction:
16 : 9 = 1 and the rest is 7 so:
1 7/9 cups of chickenChicken 1 1/2 cups:
We'll do the same thing as before:
1 1/2 = (2*1) + 1 / 2 = 3/2 of cups
3/2 * 2/3 = 1
1 cup of chicken3/4 cups or rice:
3/4 * 2/3 = 1/2
1/2 cup of riceHope this helps

Problem 3
Answer: x = 47Explanation: The angles opposite the congruent sides, are congruent angles. We consider these the base angles. This triangle is isosceles.
==================================================
Problem 4
Answer: x = 32Explanation:
Refer to the diagram below. Note how I've added in the variable y and marked another angle as 53 degrees which is one of the base angles of the left triangle. The base angles of the triangle on the right are y degrees each. Also, note the vertical angles both are y.
For the left triangle, the three angles add up to 180 which means we can solve for y to go from 53+53+y = 180 to y = 74
Then the interior angles of the triangle on the right has the three angles (y,y,x) add to 180 as well. So we have y+y+x = 180 which turns into 74+74+x = 180. That solves to x = 32
==================================================
Problem 5
Answer: x = 58Explanation:
Refer to the diagram below. I've added another base angle x, and the angle 90-x is complementary to this. This is because the two pieces must add to 90.
For the triangle on the bottom, the two base angles 74 and 74, add to the third angle 90-x and we would get 180. So we solve 74+74+(90-x) = 180 to get x = 58
Answer:
3. x = 47
4. x = 32
5. x = 58

Suppose Clara has a collection of old CDs. If the diameter of a CD measures about 12 centimeters, approximate the circumference of the CD. Round your answer to the nearest tenth of a centimeter.
Answer:
The circumference of the CD is approximately 38 cm
Step-by-step explanation:
The circumference of the CD can be seen as the distance around the CD.
The word "circumference" is used to describe the perimeter of circular objects.
To find an approximate value of the circumference of the CD, we will use this formula.
Circumference = π × diameter
let us take π to be = 3.142
∴ circumference = 3.142 × 12 = 37.6991 cm
we can round this up to teh nearest tenth as 38cm

The volume of a cylinder varies jointly as the square of the radius and the height. If the volume is 28pi cubic inches when the radius is 2 inches and the height is 7 inches, find the volume
when the radius is 12 inches and the height is 11 inches. Express the answer in terms of pi .
A. 1,728x in
B. 529x in
O C. 1,584x in
D. 1,331x in
Answer:
1584 cu in.
Step-by-step explanation:
Since the volume varies jointly with the radius and height we have an equation V = kr^2h where k is the constant of variation
28 = 2^2(7)k = 28k
k = 1
Now V = r^2h
V = (12)^2(11) = 144(11) = 1584 cu in.
