Based on similarity transformation, Since every circle is 360 degrees, so we know that their angles are congruent.

When a figure is transformed by a similarity transformation, an image is created that is similar to the original figure.

The total angle in every circle is 360 degrees, hence all circles are similar.

Thus, we can conclude the following based on similarity transformation, Since every circle is 360 degrees, so we know that their angles are congruent.

Answer:

A

Step-by-step explanation:

3 times steep means slope is 3 times

slope=4

new slope =3×4=12

translated 7 down means y intercept-7=1-7=-6

so new eq. is y=12x-6

Answer:

A

Step-by-step explanation:

So we know that the slope is 4, and we want to make it 3 times as steep, so that would be 12. The y-intercept is one and we want to move it down 7 units, 6-7= -1. So our final answer would be y= 12x-6!

Step-by-step explanation:

The triangle is right isosceles.

It is right as the side is the diameter of the circle.

It is isosceles as two sides marked as equal.

Acute angles are same and equal to:

Correct option is 45°

Answer:

<M=90°[inscribed angle on diameter is 90°]

<N=<L=[base angle of isosceles triangle]

now

<M+<l+<N=180°[sum of interior angle of traingle]

[2x-5]×2=180-90

4x-10=90

x=100/4=25

x=25

Answer:

13 miles

Step-by-step explanation:

Given that he traveled in a straight line to each destination. Then,

i. distance from his home to soccer field = [tex]\sqrt{x^{2} + y^{2} }[/tex]

                                      = [tex]\sqrt{4^{2} + 3^{2}}[/tex]

                                      = [tex]\sqrt{16 + 9}[/tex]

                                      = [tex]\sqrt{25}[/tex]    = 5 miles

ii. The distance from soccer field to the library = 8 miles.

So that we can say that;

Ryan's total distance from home to the library = 5 + 8

                                                      = 13 miles

Thus, Ryan would have traveled 13 miles by the time he reached the library.

42m

Step-by-step explanation:

Use the hypotenuse formula:

a^2 + b^2 = c^2

110^2 + 55^2 = 123^2

So Sara ussually walks 123m across the lot, now she needs to walk an extra 42m to get pass the lot.

Answer:

the area of the porch is 5 times larger

Step-by-step explanation:

Area of a rectangle = length x width

Original area = 15 x 6 = 90 square feet

length of width after it was enlarged 5 times = 5 x 6 = 30

New Area = 30 x 15 = 450 square feet

change in area = 450 / 90 = 5

Given:

Amy spent $90 at the store.

She spent [tex]\dfrac{1}{3}[/tex] of her money on food, [tex]\dfrac{1}{6}[/tex] of her money on school supplies, and [tex]\dfrac{1}{9}[/tex] of her money on soda.

To find:

How much did she spend on school supplies?

Solution:

According to the given information, Amy spend [tex]\dfrac{1}{6}[/tex] of her money on school supplies.

Amy spent $90 at the store. So,

Money spend on school supplies = [tex]\dfrac{1}{6}\times 90[/tex]

                                                        = [tex]15[/tex]

Therefore, Amy spend $15 on school supplies.

Answer:

false

Step-by-step explanation:

No, two acute angles cannot form a supplementary angle. By definition, acute angles are the angles that measure the angle greater than 0° and less than 90°. ... Example: 80° +60° = 140° which is not a supplementary angle. But, in the case, if we add more than two acute angles, we can get supplementary angles.

x = 24

Step-by-step explanation:

The ratio is x2

11 x 2 = 22

13 x 2 = 26

Therefore,

12 x 2 = 24

x = 24

Step-by-step explanation:

[tex]y = {x}^{2} + 6x + 4[/tex]

[tex]y - 4 = {x}^{2} + 6x[/tex]

[tex]y - 4 + 9 = {x}^{2} + 6x + 9[/tex]
