Hey there!

First; let us understand that there are 360° in a full circle.

<em>This is what we are representing. </em>

We need to find a way to multiply to get the answer.

<u>36% of 360 = 0.36</u>, therefore we need to make 0.36 x 360

<u>Multiply 0.36 x 360 </u>

Therefore, we <u>get 129.6°</u>

Solve Inequality <br> -14x > -112

den301095 [7]

Answer:

x <8

Step-by-step explanation:

-14x > -112

Divide each side by -14. Remember that flips the inequality

-14x/-14 < -112/-14

x <8

if a shape is a regular pentagon with five sides, which of the following must be true? Check all that apply

julsineya [31]

Answer:

A. It has reflectional symmetry

B. It is symmetrical

D. It has five lines of symmetry

Step-by-step explanation:

we know that

A regular pentagon has 5 sides and 5 lines of symmetry. The number of lines of symmetry in a regular polygon is equal to the number of sides

Every regular polygon has reflectional symmetry

Regular polygons are symmetrical

therefore

A. It has reflectional symmetry ------> Is true

B. It is symmetrical -----> Is true

C. It has exactly one line of symmetry ----> Is false

D. It has five lines of symmetry -----> Is true

What is the number if 50% of 25% of the number is 96

tamaranim1 [39]

Answer:

Step-by-step explanation:

the number is 96

hence,

25% of 96=

25/100*96/1

=24

50% of 24=

50/100*24/1=

it also possible that you're to sum them,but since you were not asked for the sum of the number the answer is 12.

Can someone help me with this

The center of the circle is (h,k) = (-2,-3)

The radius of the circle is r = 2

The standard form of equation of the circle is

${(x + 2)}^{2} + {(y + 3)}^{2} = 4$

<h3>How to find the center, radius and standrad form of the circle?</h3>

The general form of equation of the circle is

${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$

Here, (h,k) means centre of the circle.

r means radius of the circle.

given that coordinate points of centre of circle is (-2,-3).

Hence the (h,k) = (-2,-3)

<h3>How to find the radius of the circle?</h3>

Now to find the radius of the circle

The distance from a circle's centre to its circumference is its radius.

The distance from a circle's centre (-2,-3) to its circumference (0,-3) is its radius.

using the formula, distance between the two points to obtain radius.

$d = \sqrt{(x1 - x2) {}^{2} + {(y1 - y2)}^{2} } \\ r = \sqrt{ {( - 2 - 0)}^{2} + {( - 3 - ( - 3))}^{2} } \\ r = \sqrt{ {( - 2)}^{2} + {( - 3 + 3)}^{2} } \\ r = \sqrt{ {4}^{2} + 0 } \\ r = \sqrt{4} \\ r = 2$

<h3>How to find the standard form of equation of the circle?</h3>

(h,k) = (-2,-3)

r = 2

subtitue the (h,k) and r values to get the standard form of equation of the circle.

$(x - h) {}^{2} + {(y - k)}^{2} = {r}^{2}$

${(x - ( - 2))}^{2} + {(y - ( - 3))}^{2} = {r}^{2}$

${(x + 2)}^{2} + {(y + 3)}^{2} = 4$
