Answer:

160°

Step-by-step explanation:

We can use the central angle theorem for this. It says that an angle inscribed in a circle (on the circumference) measured half of the arc it intercepts (by 2 points on the circumference of the circle).

that would mean that Angle KAW is half of measure of Arc KW. Thus we can write:

m∠A = 0.5 (arc KE + arc EW)

x+45 =0.5 (x+20+3x)

x+45 = 0.5(4x+20)

x+45 = 2x + 10

45 - 10 = 2x - x

Thus, x = 35

Since Arc KW = Arc KE + Arc EW and x = 35, we can say:

Arc KW = x + 20 + 3x = 35 + 20 + 3(35) = 160°

The value of the arc KW subtended from the center of circle O is 160°.

An equation is an expression that shows the relationship between two or more numbers and variables.

From the circle O:

m KW = m KE + m EW (angle addition postulate)

m KW = (x + 20) + (3x)

m KW = 4x + 20

m KW = 2m∠A (angle subtended from center)

4x + 20 = 2(x + 45)

x = 35

m KW = 4(35) + 20 = 160°

The value of the arc KW subtended from the center of circle O is 160°.

Step-by-step explanation:

given

2x ÷ 4 = 10 or

[tex]\frac{2x}{4}[/tex] = 10 ( multiply both sides by 4 )

2x = 40 ( divide both sides by 2 )

x = 20

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

(b)

He may have mistaken the ÷ for  a - (subtraction sign )

2x - 4 = 10 ( add 4 to both sides )

2x = 14 ( divide both sides by 2 ), leading to

x = 7 ← the incorrect answer he obtained

Step-by-step explanation:

For this case we must indicate the graph corresponding to the following inequality:

[tex]y <\frac {3} {4} x + 2[/tex]

As it is observed that equality is not included, we can discard options C and D. We are left with the graphs of the dotted border line.

Graphic A:

We evaluate in the inequality the point [tex](0,0)[/tex]

[tex]0 <\frac {3} {4} (0) +2\\0 <2[/tex]

The inequality is met.

Thus, the inequality is represented in graph A.

Answer:

Option A

Answer:

Step-by-step explanation:

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

[tex] d = \sqrt{(-6 - 10)^2 + [7 - (-5)]^2} [/tex]

[tex] d = \sqrt{(-16)^2 + (7 + 5)^2} [/tex]

[tex] d = \sqrt{256 + 12^2} [/tex]

Answer:

V = 96 cubic inches

Step-by-step explanation:

Volume of a rectangular prism is V= LWH,  

we are given W = 4, L = 8, and H = 3.  Plug  them in and find W...

V = (4)(8)(3)

   V = 32(3)

      V = 96 cubic inches

Answer: OPTION A

Step-by-step explanation:

Descompose the number 20 into its prime factors:

[tex]20=2*2*5=2^2[/tex]

Because, by definition:

[tex]\sqrt[n]{a^n}=a[/tex]

 Then, you must rewrite 2²*5 inside of the square root, as following;

[tex]\frac{3\sqrt{2^2*5}}{\sqrt{5}}[/tex]

Simplify as following:

Keeping on mind that [tex]\sqrt[n]{a^n}=a[/tex], then:

[tex]\frac{3*2\sqrt{5}}{\sqrt{5}}[/tex]

 Note:

[tex]\frac{\sqrt{5}}{\sqrt{5}}=1[/tex]

Then:

[tex]\frac{6\sqrt{5}}{\sqrt{5}}=6(1)=6[/tex]

Therefore, as you can see the answer is the option A

Answer:

option A)

The Answer to your question is:

B: (2,-5)

Answer:

the vertex is (2,-5)

Step-by-step explanation:

f(x) = 6|x − 2| − 5

WE need to find out the vertex of the given absolute function

The vertex form of absolute function is

f(x) = a|x − h| +k

where (h,k) is the vertex

Now we compare the given f(x) with the vertex form

h= 2  and k = -5

so the vertex is (2,-5)

To recreate a drawing on a new scale of 1 cm to 4 cm, simply multiply the original dimensions by the scale factor of 4.

If you are given a drawing and you want to recreate it on a new scale where 1 centimeter (cm) in the original equals to 4 centimeters in the new drawing, then you simply have to multiply the dimensions of the original by 4. Suppose the original drawing is 2 cm in length and 3 cm in width. Then the new length would be 2 cm * 4 = 8 cm and the new width would be 3 cm * 4 = 12 cm. Remember this is a general concept and can be applied to all dimensions of the drawing. It's a basic concept in proportion and scale factor.

Answer:

x = 5                         x = 1

Step-by-step explanation:

−3|x − 3| = −6

Divide each side by -3

−3/-3|x − 3| = −6/-3

|x − 3| = 2

An absolute value is equal to a positive and negative solution

x-3 =2      and      x-3 = -2

Add 3 to each side

x-3+3 = 2+3            x-3+3 = -2+3

x = 5                         x = 1

Answer:  40°

Step-by-step explanation:

There are 4 pink angles (labeled as "a") and each are the same measure.

There are 4 green angles (labeled as "b") and each measure 50°.

A circle is 360°

4a + 4b = 360

4a + 4(50) = 360

4a + 200 = 360

4a           = 160

Answer:

(x+10) and (x-10)

Step-by-step explanation:

The volume of a rectangular box is defined as

Volume = width*height*length

In this case

Volume  = 6x^2-600  =  6*(x^2 - 100)

And we also know,

Volume  =  (6)*height*length

So,

6*(x^2 - 100) = (6)*height*length

This means that

height*length = (x^2 - 100)

height*length = (x+10)*(x-10)

Final answer:

The number of reading groups can be determined by dividing the total number of students, which is 24, by the number of students in each group, which is 4. The calculation is 24 ÷ 4, resulting in 6 reading groups.

Explanation:

To find the number of reading groups, we can use a simple division operation because we are dividing a larger group of items (students) into smaller equal-sized groups. In this case, we have 24 students and want to find out how many groups of 4 students we can create from that total.

Here's the step-by-step explanation:

Identify the total number of students, which is 24.

Identify the number of students in each reading group, which is 4.

Divide the total number of students by the number of students in each group: 24 ÷ 4 = 6.

Therefore, there are 6 reading groups.
