Si ahorré $2000 para comprarme ropa y al llegar a la caja de cobro me dicen
que son $2600, los cuales los pago usando una tarjeta de crédito ¿Cómo
represento la cantidad de dinero que tengo y debo? Si posteriormente le pido
prestado a un amigo $650 y me doy cuenta de que debo de la mensualidad de
mi celular 3 meses que son $250 ¿Cuánto dinero tengo y como lo represento
esta cantidad? Al final de los dos procesos ¿Cuánto dinero tengo o adeudo?​

Answers

Answer 1

Answer:

La cantidad de dinero adeuda al final de los dos procesos es $1450

Step-by-step explanation:

Los parámetros del proceso son;

La cantidad ahorrada para comprar ropa = $2,000

La cantidad pagada por la ropa = $2600

La cantidad prestada a un amigo = $650

La cantidad adeuda por teléfono celular durante 3 meses = $250

Deje que 'C', represente la suma de las transacciones anteriores, tenemos;

∴ C = 2,000 - 2,600 - 650 - 200 = -1,450

La suma de las transacciones anteriores, C = -$1,450

Por lo tanto, al final de los dos procesos, la cantidad de dinero adeuda es C = $1,450

A man weighing 800 N is hanging from a 2 mm diameter titanium wire with a cross-section of 3 x 10^-6 m^2. Will the wire break?

Answers

Answer:

Since stress is greater than ultimate strength, the wire will break.

Step-by-step explanation:

The titanium wire is experimenting an axial load. Ultimate strength equals [tex]2.20\times 10^{8}\,Pa[/tex]. The wire shall break if and only if stress is at least equal to ultimate strength. The equation for axial stress ([tex]\sigma[/tex]), measured in pascals, in the wire with circular cross-section is:

[tex]\sigma = \frac{4\cdot F}{\pi\cdot D^{2}}[/tex] (1)

Where:

[tex]F[/tex] - Axial force, measured in newtons.

[tex]D[/tex] - Cross-section diameter, measured in meters.

Please notice that axial force is the weight of the man hanging from wire.

If we know that [tex]F = 800\,N[/tex] and [tex]D = 0.002\,m[/tex], then the axial stress experimented by the titanium wire is:

[tex]\sigma = \frac{4\cdot (800\,N)}{\pi\cdot (0.002\,m)^{2}}[/tex]

[tex]\sigma \approx 2.546\times 10^{8}\,Pa[/tex]

Since stress is greater than ultimate strength, the wire will break.

The ratio of students to teachers at a school is 19 : 1. At this school, there are 400 people (teachers and students). How many of these 400 people are students? (enter number only, without the unit)

Answers

Answer:

There are 380 students and 20 teachers.

Answer:

380

Step-by-step explanation:

Let 19x =  no. of students

        x =  no. of teachers

Then,  x + 19x = 400

20x = 400

x = 20

19x = 19(20) = 380

Step-by-step explanation:

coeffecients with the same variable can be multiplied added subtracted divided so i multiplied 7 and 4 because they have the same variable which is X so it would be 28x and you can't multiply 7x by 5 because it doesnt have a variable consider multiplying if it has the same variable when it has a variable. so it would just be 28x - 5

Write the equation of a line that is parallel to the line y=4x+2 and passes through the point (4,1)

Answers

Answer:

y = 4x-13

Step-by-step explanation:

The standard equation of the line is y = mx+c

m is the slope

c is the intercept

Given the equation y = 4x+2

The slope m = 4

Substitute m = 4  and the given point into the formula y = mx+c

1 = 4(4)+c

1 = 14+c

c = -13

Get the equation

Recall that y = mx+c

y = 4x + (-13)

y = 4x-13

Hence the required equation is y = 4x-13

What conclusion can you make from the information below?
Three boys (Dmitri, Ken, and Adam) have three different favorite colors (red,green, and blue)
• Dmitri does not like red
• Adam does not like red.

A. Dmitri's favorite color is blue.
B. No one likes green
C. Ken's, favorite color is red
D. Ken's favorite color is not red.​

Answers

C. Kens favorite color is red
Answer: C. Ken's favorite color is red

========================================================

Explanation:

We're told that Dmitri and Adam do not like red. So that must mean that Ken likes red. This immediately leads to choice C as the answer. This is assuming that each boy picks one of the three colors (and no colors can be repeated).

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

Extra info:

Choice A is false because we're not sure if Dmitri likes blue or green. We don't have enough info. Choice B is false because someone has to pick green. There are three boys and three colors. Again I'm assuming each person picks one color and the colors aren't repeated.Choice D is false because it contradicts choice C.

Answer:

Four possible values of x: 10, 3, 20, 31

Writing it in ascending order : 3, 10, 20, 31, 33

Step-by-step explanation:

Because x is a positive integers it means that x could be any number that goes from zero to infinity.

The possible values of x such that 33/x remains a positive integer in ascending order are 1,3,11 and 33.

What is an integer?

An integer is a whole number irrespective of the sign that the integer is all whole numbers that are going from 0 to infinite or 0 to minus infinite.

Integer ; ....-2 , -1 , 0 , 1 , 2 , .....

Given the expression, 33/x

Now positive integers are whole numbers ( 1,2,3,...)

To 33/x be the whole number and x is also a positive integer.

33/1 = 33 (1,3 Positive integer)

33/3 = 11 (3,11 Positive integer)

33/11 = 3 (11,3 Positive integer)

33/33 = 1 (33,1 Positive integer)

Hence "The possible values of x such that 33/x remains a positive integer in ascending order are 1,3,11 and 33".

Today, a lighthouse is commonly known as a type of tower that shines a large lamp out to the sea. The light helps to mark dangerous areas along a coast. A lighthouse also gives notice to a ship that land is near. Many lighthouses were constructed in the 17th century. The first lighthouse in the U.S. was built in 1716 in Boston Harbor. Nearly 1,000 lighthouses were built by 1900 in the U.S. After this point, many lighthouses were abandoned and became rundown as a result. In the U.S., the coast guard oversees the lenses and lamps of the countrys lighthouses. In more recent years, the destruction of lighthouses has been rising. Groups have formed in order to restore lighthouses. Often, these lighthouses are made into parks, museums, research centers, and even inns or hotels to stay at overnight.and here is the question: Groups that restore lighthouses would most likely agree with which of the following? A. Lighthouses should all be restored so they are the same size and shape. B. Lighthouses are an important part of history that should be preserved. C. Lighthouses are no longer useful with today's computerized technology. D. Lighthouses should be owned and operated by the national government.
