The image of (6, 9) under a dilation is (4, 6). The scale factor is 0-2 O 2/3 0 -2/3

lisov135 [29]

Answer:

$\frac{2}{3}$

Step-by-step explanation:

To determine the scale factor consider the ratio of the image coordinates to the original coordinates, that is

scale factor = $\frac{4}{6}$ = $\frac{6}{9}$ = $\frac{2}{3}$

What total length of ribbon is needed to Line the two long sides of the hat?

frozen [14]

Answer:

Total length of ribbon to line the long sides will be 22 in

Step-by-step explanation:

In the given figure of kite if we draw a line "h" vertically will form two right angle triangles.

Then by applying Pythagoras theorem in both the triangles.

h²= (3x + 5)² + (2x + 1)² ------(1)

h²= (5x + 1)² + 5² ------(2)

By equating both the equations

(3x + 5)² + (2x + 1)² = (5x + 1)² + 25

9x² + 25 + 30x + 4x² + 4x + 1 = 25x² + 10x + 1 + 25

13x² + 34x + 26 = 25x² + 10x + 26

13x² - 25x² + 34x - 10x + 26 - 26 = 0

- 12x² + 24x = 0

12x² - 24x = 0

x² - 2x = 0

x(x - 2) = 0

x = 2

Now we will put x = 2 in the measure of sides of the kite.

Side 1 = (3x + 5)

= 3×2 + 5

= 11

Side 2 = (5x + 1)

= 5×2 + 1

= 11

Side 3 = (2x + 1)

= 2×2 + 1

= 5

Therefore, Total length of ribbon to line the long sides will be = 11 + 11

= 22 in.

WORKSHEET-2

Margarita [4]

Answer:

1. $\frac{C}{D}$ = 3.143

2. Circumference

3. Area of the circle is 3850 $cm^{2}$ .

ii. Circumference of the circle is 220 cm.

Step-by-step explanation:

The area, A, and the circumference, c, of a circle can be determined respectively by:

A = $\pi$ $r^{2}$

C = 2 $\pi$ r

where r is the radius of the circle.

1. the ratio of the circumference and diameter, D, of a circle is:

r = $\frac{D}{2}$

so that,

C = 2 $\pi$ $\frac{D}{2}$

C = $\pi$ D

$\frac{C}{D}$ = $\pi$

= $\frac{22}{7}$

= 3.143

2. The distance around a circular region is known as it's circumference.

3. Given a circle of radius 35 cm, then:

A = $\pi$ $r^{2}$

= $\frac{22}{7}$ x $(35)^{2}$

= $\frac{22}{7}$ x 1225

= 22 x 175

A = 3850

Area of the circle is 3850 $cm^{2}$ .

C = 2 $\pi$ r

= 2 x $\frac{22}{7}$ x 35

= 2 x 22 x 5

= 220

C = 220 cm

Circumference of the circle is 220 cm.
