David ha fabricado una caja de cartón sin tapa para guardar sus cromos la caja tiene una base cuyos lados miden 30 cm y cuya altura mide 10 cm calcula la cantidad de cartón que ha necesitado David

Answers

Answer 1

Answer:

Se requieren 210 cm de cartón con un lado = 10 cm

Se requieren 70 cm de cartón con un lado = 30 cm

Explanation:

Spanish

Primero calcularemos el área de la superficie de la caja sin la tapa.

Los lados son de 30 cm, por lo que largo = ancho = 30 cm y alto = 10 cm

Superficie del fondo = largo * ancho = 30 * 30 = 900 cm²

Área de superficie de la parte delantera y trasera = 2 * alto * ancho = 2 * 10 * 30 = 600 cm²

Área de superficie del lado izquierdo y derecho = 2 * largo * alto = 2 * 30 * 10 = 600cm²

Superficie total = 900 + 600 + 600 = 2100 cm²

Entonces, si dividimos la superficie total por un lado (altura) = 2100cm² / 10cm = se requieren 210 cm de cartón

Se requieren 210 cm de cartón con un lado = 10 cm

o si dividimos la superficie total por un lado (largo) = 2100cm² / 30cm = se requieren 70 cm de cartón

Se requieren 70 cm de cartón con un lado = 30 cm

English

First we will calculate the surface area of the box without the lid.

The sides are 30 cm so length=width= 30 cm and height = 10cm

Surface area of the bottom = length *width = 30*30= 900 cm²

Surface area of  front and back = 2*height * width = 2*10*30= 600 cm²

Surface area of left and right side = 2*length*height = 2*30*10= 600cm²

Total surface area= 900+600+600= 2100 cm²

So if we divide the total surface area by one side ( height ) = 2100cm²/ 10cm= 210 cm of card board is required

210 cm of card board is required  with one side = 10 cm

or if we divide the total surface area by one side ( length ) = 2100cm²/ 30cm= 70 cm of card board is required

70 cm of card board is required  with one side = 30 cm

C They often are about people who lead relatively ordinary lives and have not done anything famous.
D They use exaggerations to make their points.

Answers

Answer:

C They often are about people who lead relatively ordinary lives and have not done anything famous.

Explanation:

In the past, biographies and autobiographies were only written about important people, Kings, or noble men and rarely of the common man. However, in recent times, more autobiographies and biographies have been written about the commoner.

Therefore, some modern biographies and autobiographies are different from classic biographies and autobiographies in terms of content because they often are about people who lead relatively ordinary lives and have not done anything famous.

Answers

it is D as you can see it what it is and from the info you gave me i belive it is D

The paragraph best supports the statement that Peace Corps employees have both academic and work experience. The correct option is D.  

Thus, The statement that employees of the Peace Corps are hired for a finite period of time is best supported by the text, as stated in option c.

According to the sentence, "to keep the agency dynamic with fresh ideas, no staff member can work for the agency for more than five years." This supports the notion that employees are hired for a certain period of time by implying that there is a time restriction for employment with the Peace Corps.

The paragraph does not explicitly support the alternative possibilities.

Thus, The paragraph best supports the statement that Peace Corps employees have both academic and work experience. The correct option is D.

Answers

Answer:

b. a comma

Explanation:

A comma represents a brief pause in the text. Usually indicating that there is a connection but also a separation between two statements. A quote is connected to the text because the text is describing the quote or the individual who is speaking but is also separate from the text itself. Therefore, a comma would be used to signal this separation and allow the proper introduction of the quote.

What is the inference about White Fang?

From the concluding part of the text, we can see that White Fang was quite protective of his master.

When a man and woman came near his master and the woman clutched her hands around the master, we can see that White Fang began snarling and raging like a demon.

He felt that the people wanted to harm the master but Scott convinced White Fang that this was not the case. So, we can say that White Fang was protective of its master.
