Plz help is the statements true or false

<h3>Answers:</h3>

(a) True
(b) True
(c) False
(d) True
(e) False

========================================================

Explanations:

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

Part (a)

Applying a rotation will not change the length of XY. This means segment X'Y is the same length as segment XY.

Put another way: (distance from X to Y) = (distance from X' to Y)

So if we have Y as the center of the circle, and XY as the radius, then X and X' are both on the same circle.

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

Part (b)

As explained in part (a), the segments XY and X'Y are both radii of the same circle, so they are equal to one another.

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

Part (c)

Draw a right triangle with side lengths XY, X'Y and hypotenuse XX'

Note how a 45-45-90 triangle forms. We can use the pythagorean theorem to show that XX' is larger than XY. Therefore, XX' and XY aren't equal.

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

Part (d)

This angle forms because we rotated point X 90 degrees with the center point as Y. It might help to think of point Y at the origin. So that's why this statement is true.

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

Part (e)

This is false because segment X'Y or YX' is a radius and not a diameter. We would need to multiply by 2 to get a diameter.

A regular hexagon inscribed in a circle is approximately 0.827 times the area of that same circle. What percentage of the circle

tatyana61 [14]

a. The percentage of the circle occupied by the hexagon is 82.7%

b. The percentage of the circle not occupied by the hexagon is 17.3%

Step-by-step explanation:

a regular hexagon inscribed in a circle is approximately 0.827 times the

area of that same circle

1. Assume that area the circle is x

2. Find the ratio of area hexagon to area circle

3. Change The ratio to percentage

4. Subtract area hexagon from area circle to find the area not occupied

by the hexagon and do the same steps 2 and 3 with the area not

occupied and the circle

∵ The regular hexagon inscribed in a circle

∴ Area the circle > area of the hexagon

∵ Area the circle is x

∵ Area the hexagon is 0.827 times the area of the circle

∴ Area hexagon = 0.827(x)

∵ The ratio between area hexagon and area circle = $\frac{0.827x}{x}$

- Cancel x up with x down

∴ The ratio between area hexagon and area circle = 0.872

- Change the ratio to percentage by multiply it by 100%

∴ The percentage of area hexagon to area circle = 0.827 × 100%

∴ The percentage of area hexagon to area circle = 82.7%

a. The percentage of the circle occupied by the hexagon is 82.7%

∵ Area the circle is x

∵ Area the hexagon is 0.827 x

∴ The area not occupied by the hexagon = x - 0.827 x

∴ The area not occupied by the hexagon = 0.173 x

The ratio between area not occupied by the hexagon and area circle

= $\frac{0.173x}{x}$

- Cancel x up with x down

∴ The ratio between area not occupied by the hexagon and area

circle = 0.173

- Change the ratio to percentage by multiply it by 100%

∴ The percentage of area not occupied by the hexagon to area

circle = 0.173 × 100%

∴ The percentage of area not occupied by the hexagon to area

circle = 17.3%

b. The percentage of the circle not occupied by the hexagon is 17.3%

The actual length (L) of a rectangle is 27 centimeters.

muminat

You just need to multiply the length with the ratio

for example, if the ratio is :2w : 3L , the actual width would be 2/3 x 27

= 18 cm
