Answer:

A ≈ 194.8 units²

Step-by-step explanation:

the shaded area (A) is calculated as

A = area of outer circle - area of inner circle

   = πr₁² - πr₂² (r₁ is outer radius and r₂ the inner radius )

  = π × 13.5² - π × 4.5²

 = π(13.5² - 4.5²)

 = π(182.25 - 20.25)

 = π × 62

 ≈ 194.8 units² ( to the nearest tenth )

Answer:

The ratio of the perimeters is 3

The ratio of the areas is 9

Step-by-step explanation:

Given:

Dilate a triangle with vertices (0, 0), (0, 2), and (2,0) using the scale factor k = 3.

To Find:

What is the value of the ratio (new to original) of the perimeters? the areas?

Solution:

What is the value of the ratio (new to original) of the perimeters?

Since, two figures are similar, then the ratio of its perimeters is equal to the scale factor

Let the following be:

k        ⇒          the scale factor

x        ⇒          the perimeter of the new triangle

y        ⇒          the perimeter of the original triangle

Knowing that:

k = x/y

Thus:

k = 3

Now Substitute:

x/y = 3

-------------------------------------------------------------------------------------------------------------

What is the value of the ratio (new to original) of the areas?

Since, two figures are similar, then the ratio of its areas is equal to the scale factor squared.

k       ⇒          the scale factor

x        ⇒          the area of the new triangle

y        ⇒          the area of the original triangle

k ² = x/y

Since,

z = 3

Then,

x/y = 3 ²

3 ² means to 3 × 3

x/y = 9

Solving :

Explanation:

Imagine that you have a rope staked into the ground at one end. The other end is allowed to move freely. At this freely moving endpoint, imagine white chalk is spread on the grass. The chalk would draw out a circle. Each point on the white chalk circle is the same distance away from the center.

Another example: we have a campfire and campers gather around it. The fire itself is the center. The campers would be on the edge of the circle if they are the same distance away from the fire (eg: all of them 5 feet away from the fire).

Answer: A:2 R8

This image should help, but first, you should find the biggest number that 27 can be multiplied by, but stay under 62, which in this case is 2, because 27*3=81 and 2 is the maximum it can be while staying below 62. which makes the equation turn into 62-54=8, making the remainder 8.

Astronomy is written in clear non-technical language, with the occasional touch of humor and a wide range of clarifying illustrations. It has many analogies drawn from everyday life to help non-science majors appreciate, on their own terms, what our modern exploration of the universe is revealing. The book can be used for either a one-semester or two-semester introductory course (bear in mind, you can customize your version and include only those chapters or sections you will be teaching.) It is made available free of charge in electronic form (and low cost in printed form) to students around the world. If you have ever thrown up your hands in despair over the spiraling cost of astronomy textbooks, you owe your students a good look at this one.

Astronomy has information and images from the New Horizons exploration of Pluto, the discovery of gravitational waves, the Rosetta Mission to Comet C-G, and many other recent projects in astronomy. The discussion of exoplanets has been updated with recent information—indicating not just individual examples, but trends in what sorts of planets seem to be most common. Black holes receive their own chapter, and the role of supermassive black holes in active galaxies and galaxy evolution is clearly explained. Chapters have been reviewed by subject-matter experts for accuracy and currency.

A parallelogram is a quadrilateral with both pairs of opposite sides parallel.

A rectangle is a parallelogram with all right angles, so yes, every rectangle is a parallelogram.

A square is a parallelogram with all right angles and all congruent sides; since it is a parallelogram with all right angles, every square is a rectangle.

A rhombus is a parallelogram with all congruent sides.

Since a square is a parallelogram with all congruent sides, then every square is a rhombus.

A trapezoid is a quadrilateral with one pair of parallel sides. Since a rhombus is a parallelogram, with 2 pairs of parallel sides, rhombus are not trapezoids.

The distance between the two points  (1,1) and (3,-4) , using the distance formula in the radical symbol, is √(29).

To measure the distance between two points of a coordinate system, the formula can be given as,

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Here, (x₁, y₁) are the coordinates of point 1 and  (x₂, y₂) are the coordinates of point 2.

The distance between the two points. (1,1), (3,-4)​ has to be find out. Use the distance formula to find the distance between them,

[tex]D=\sqrt{(1-3)^2+(1-(-4))^2}\\D=\sqrt{(-2)^2+(5)^2}\\D=\sqrt{4+25}\\D=\sqrt{29}[/tex]

Thus, the distance between the two points  (1,1) and (3,-4) , using the distance formula in the radical symbol, is √(29).
