Find the measure of each number angle:

Answers

Answer:

12. 6= 68°

15. 4= 52°

Step-by-step explanation:

12.

since 5= 22°

5+6= 90° since it Is a right angle

6= 90-22

therefore 6 is 68°

15.

since 3 is 38°

and 3+4= 90° since it is a right angle

4= 90-38

therefore 4 is 52°

DE=4

Step-by-step explanation:

got it right on edg

The length of DE is given as: 3 Units. (Option B)
A line that joins two points on a curve is called a Secant Line.

What is the Secant Theorem?

Two secant theorem states that if two secant lines are drawn from a point outside a circle a relationship is formed between the line segments.

How do we arrive at the length of DE?

Based on the Secant Theorem, from the figure, we know that:

AX * BX = EX * DX

Assuming that the length of DE equals X,:

AX * BX = EX * DX

Equals

(7+2) X (2) = (x + 3) (3)

To solve for x we expand the brackets to state:

9 * 2= 3x + 9

3x = 18-9

3x= 9

x = 9/3

X which is same as DE = 3 Units.

A child toy is made by removing a triangular prism from the center of a wooden rectangular prism The triangular base of the triangular prism has a base length of 1 inch and a height of 1 inch. Write and solve an equation to find the volume of the toy.

Answers

*see attachment for the diagram given

Answer:

Volume of the toy = 68 in.³

Step-by-step explanation:

The equation to find the volume of the toy = volume of the wooden rectangular prism - volume of the triangular prism removed form the center

Volume of the toy = (L*W*H) - (½*bhl)

Where,

L = 8 inches

W = 3 inches

H = 3 inches

b = 1 inch

h = 1 inch

l = 8 inches

Plug in the values into the equation

Volume of the toy = (8*3*3) - (½*1*1*8)

Volume = 72 - 4

Volume of the toy = 68 in.³

HHHHHHHHHHHHHELLLLLPPPPPPP ME PLS PLS PLS a school wants to add a new sports team. The school sent out surveys asking for the students' favorite sport. seventeen students named swimming. Others named hockey or volleyball . Use pencil and paper. Explain how to use the circle graph and ratios to find the number of students surveyed. Then find this number.

Answers

Answer:

Total 100% or 25 students

Swimming 36% or 9 students

Lacrosse 48% or 12 students

Volleyball 16% or 4 students

Step-by-step explanation:

To do a circle graph, you draw a circle and divide it into all sections.

To know the size of each section, you need to know the total number of every category.

You could draw it with percent.

100% is total, and you know the percent of each sport.

They told you 12 students choose lacrosse so, this represents 48%.

Now, you can find the other numbers with cross-multiplication.

48%____12

100%____X=

X=(100x12)/48=25

Total students: 25

Students that named lacrosse: 12 or 48%

100%____25

16%____X=

X=(16x25)/100=4

Students that named Volleyball: 4 or 16%

100%____25

36%____X=

X=(36x25)/100=9

Students that named Swimming: 9 or 36%

To confirm: 12 + 9 + 4 = 25

Step-by-step explanation:

Find two negative consecutive integers such that the square of the first is five more than the second. Find the integers.

Answers

Answer:

the two consecutive negative integers are -2 and -1.

Step-by-step explanation:

Represent these negative integers by m and n.

Then (because the integers are consecutive) n = m + 1, and m^2 = n + 5.

Substituting m + 1 for n in the second equation, we get:

m^2 = m + 1 + 5, or

m^2 - m - 6 = 0

This factors into (m - 3)(m + 2) = 0. The only negative root is -2.

Thus, the two consecutive negative integers are -2 and -1.

Check: Is the square of the first five more than the second?

Is (-2)^2 = -1 + 5? YES

The integers aer -2 and -1.

Solve: 4x^2 = 32 thanks

Hey there!

ASSUMING

2(3r + 4) - 3 (r + 1) = 11

IF SO

2(3r + 4) - 3 (r + 1) = 11

2(3r + 4) - 3 (1r + 1) = 11

DISTRIBUTE

2(3r) + 2(4) - 3(1r) - 1(1) = 11

6r + 8 - 3r - 1 = 11

COMBINE the LIKE TERMS

(6r - 3r) + (8 - 3) = 11

6r - 3r + 8 - 3 = 11

3r + 5 = 11

SUBTRACT 5 to BOTH SIDES

3r + 5 - 5 = 11 - 5

SIMPLIFY!

3r = 11 - 5

3r = 6

DIVIDE 3 to BOTH SIDES
3r/3 = 6/3

SIMPLIFY!

r = 6/3

r = 2

Therefore, the answer should be: r = 2

Trade organizations such as the World Trade Organization and the European Union were being created, and global markets were starting to open up more and more as time went on. Popular and consumer culture was diffused through this process of increasing relations, as popular culture in other countries could be spread, and common consumer culture was easily spread through the increasingly prevalent global market that was being created. B) One way in which entertainment shows the influence of globalized society is the fact that entertainment in foreign countries often shows the effects of westernization. What I mean by this is that in other countries such as ones in Eastern Asia and the Western Pacific, often watch American or European media, and this influences their customs, and influences society as a whole. Entertainment itself is an effect of globalization, as many TV shows are made overseas and are marketed to foreign audiences, which wouldnt be able to happen without globalization. So, entertainment very effectively shows the influence of globalized society, as it shows how foreign businesses can now easily make it onto the most used household appliances. C) One way in which consumer culture became globalized and went beyond national border is the introduction of technology as a medium of shopping. Technology has heavily advanced the consumer experience, as you can shop from anywhere in the world, and get a product made anywhere in the world, and get it shipped right to you. Consumer culture has become globalized through this, and has easily gone beyond national borders, as there are little restrictions on e-commerce as compared to regular commerce, and the globalization of consumer culture has increased rapidly as a result.
