Step-by-step explanation:

first you substiture the y in the second equation with the first

x-2x=10

then solve

1x-2x=-1

multiply both sides by a negative to make the varible a

positive

x=-10

now we substitue the x in the first equation with -10

Answer:

UT = 8

Step-by-step explanation:

From the picture, we can make the following equation...

5 + 2x - 6 = x + 6

By solving it we get

5 + 2x - 6 = x + 6

2x - 1 = x + 6

2x = x + 7

x = 7

Therefor if UT = 2x - 6, then UT is equal to...

2x - 6 = UT

2(7) - 6 = UT

14 - 6 = UT

8 = UT

Which of the following two-dimensional shapes can be rotated to create a sphere?

A. Triangle
B. Square
C. Circle
D. Ellipse

please give an explanation and not just a letter or answer. Thank you.

Answers

The answer is C. circle because a sphere is formed by rotating a circle by any of its diameters

The shape that can be rotated to create a sphere is the circle (option C).

A sphere is a three-dimensional object with all points equidistant from its center. When a circle is rotated about its center axis, it creates a three-dimensional shape that perfectly matches the definition of a sphere.

Let's consider the other options and why they cannot be rotated to form a sphere:

A. Triangle: A triangle is a two-dimensional shape with straight sides. Rotating a triangle around any axis would not result in a three-dimensional shape with all points equidistant from its center, which is the defining characteristic of a sphere.

B. Square: Similarly, a square is a two-dimensional shape with straight sides. Rotating a square around any axis would not create a sphere, as it would still retain its flat, planar nature.

D. Ellipse: An ellipse is a two-dimensional shape resembling a squashed or stretched circle. Rotating an ellipse would not result in a sphere, as it would still retain its elliptical shape.

Therefore, the shape that can be rotated to create a sphere is the circle (option C) due to its symmetrical and curved nature.

What 3-dimensional figure can be created by folding the shape shown below on the dotted lines?

Answers

Answer:

A triangle

Step-by-step explanation: The two squares lean against each other

The prism can be created by folding the shape on the dotted lines.

What is net?

"It is a pattern of a figure on the figure that can be folded to form the three-dimensional geometric structure."

What is a triangular prism?

"It is a prism that made up of two triangular bases and three rectangular sides."

What is cube?

"It is a three-dimensional geometric structure, which has six square faces."

What is pyramid?

"It is three dimensional geometric structure which has a polygonal base and triangular lateral sides."

For given example,

We have been given a net of a three-dimensional figure.

The net consists of three squares and two triangle.

If we create a three-dimensional structure by folding the shape on the dotted lines, then it would be a triangular prism.

As we know the triangular prism consists of three rectangular / square sides and two triangular bases.

Therefore, the prism can be created by folding the shape on the dotted lines.

They each have 4 million labor hours available per week that they can use to produce jeans, corn, or a combination of both. The following table shows the amount of jeans or corn that can be produced using 1 hour of labor. Jeans CornCountry (Pairs per hour of labor) (Bushels per hour of labor)Arcadia 8 16Felicidad 5 20Initially, suppose Arcadia uses 1 million hours of labor per week to produce jeans and 3 million hours per week to produce corn, while Felicidad uses 3 million hours of labor per week to produce jeans and 1 million hours per week to produce corn. Consequently, Arcadia produces 8 million pairs of jeans and 48 million bushels of corn, and Felicidad produces 15 million pairs of jeans and 20 million bushels of corn. Assume there are no other countries willing to trade goods, so, in the absence of trade between these two countries, each country consumes the amount of jeans and corn it produces.Arcadia's opportunity cost of producing 1 pair of jeans is____of corn, and Felicidad's opportunity cost of producing 1 pair of jeans is____of corn. Therefore,____has a comparative advantage in the production of jeans, and____has a comparative advantage in the production of corn. Suppose that each country completely specializes in the production of the good in which it has a comparative advantage, producing only that good. In this case, the country that produces jeans will produce ___ million pairs per week, and the country that produces corn will produce ____ million bushels per week.When the two countries did not specialize, the total production of jeans was 23 million pairs per week, and the total production of corn was 68 million bushels per week. Because of specialization, the total production of jeans has increased by____million pairs per week, and the total production of corn has increased by____million bushels per week.Because the two countries produce more jeans and more corn under specialization, each country is able to gain from trade.Calculate the gains from tradethat is, the amount by which each country has increased its consumption of each good relative to the first row of the table.
