A      

                              The Second Industrial Revolution was another great leap forward in technology and society. New innovations in steel production, petroleum and electricity led to the introduction of public automobiles and airplanes. You wanna know how everything began? Let's see

The Second Industrial Revolution, which began in the middle of 19th century (1850-1970). It was a period of growth for pre-existing industries and expansion of new ones; such as the steel, oil and electricity fields. The development of new technologies led to the introduction of two things that would change the world: public transport and planes.

During the Second Industrial Revolution, the existing manufacturing and production methods were improve. For instance, steel replaced iron in the building business. It was strong and it was cheap. So, it made possible to build rail lines at competitive cost and spread transportation. Steel also facilitated the construction of ships, skyscrapers and larger bridges.

Steel displaced iron because it was stronger and cheaper

Although the Second Industrial Revolution happened just a few years after the first Industrial Revolution, it was as big of a leap forward as its predecessor. If you are reading this now, surely you can't imagine a world without electricity! But at the time of the Second Industrial Revolution, this was the norm.

Faraday started playing with the idea of electricity. Then, a few years later, Edison and Swan perfected their design of a lightbulb which was practical for home use.

This, in addition to the appearance of the first efficient commercial electrical generators in the 1870s, made public electricity possible.

Swan took his incandescent lightbulbs to England. The English used Swan's lightbulbs to light Mosley Street in Newcastle upon Tyne. So, this was the first electrical street lighting installation in the world. Then, Swan gifted the Savoy Theatre in London with 1,200 of his lightbulbs. Thus making it the first public building to be lit entirely by electricity.

Mosley Street and the Savoy Theatre set the stage for the first large-scale power station. It was located at the Holborn Viaduct in London. Then followed the power station at Pearl Street in New York. Afterwards, Sebastian de Ferranti thought of "stepping down" high-voltage alternating current. De Ferranti's idea enabled the assembly line and mass production.

Denzel has a new puppy that weighs 12 pounds. The vet says that the puppy is now at about 20% of its adult weight. What will be
olchik [2.2K]

Answer:

60 pounds

Step-by-step explanation:

To find the adult weight, multiply 12 by 5.

Since 12 pounds is 20% of the adult weight, 100% of the adult weight would be 12 times 5.

12(5)

= 60

So, the adult weight of the puppy will be 60 pounds

What did i do wrong?
irakobra [83]

Answer:

27x +42+ 3x²

Step-by-step explanation:

so im learning this rn in class and what you do is FOIL

So its stands for

First

Outside

Inside

Last

(3x+6)(x+7)

(3x+6)(x+7) -- 3x² (if you have x times x it is x to the second power)

(3x+6)(x+7) -- 21x

(3x+6)(x+7) -- 6x

(3x+6)(x+7) -- 42

Now add 21x and 6x

27x +42+ 3x²

you must have added the 21 and 6 incorrectly.

The ratio of pens to pencils in Mrs. Bosworth's desk is 4:1. What does this mean?
anzhelika [568]
If there are 4 pens there will be 1 pencil, if there is 1 pencil there will be 4 pens
If the ratio is factored to a number, let's say 3, then there will be 12 pens for every 3 pencils

Rearrange the first inequality to match the second inequality and fill in the blanks for the variables. Then select the appropri
balandron [24]

Answer:

The solution set would be all real numbers

Step-by-step explanation:

Remember that you should pass from one side to the other the terms which are similar, that is to say x with x and numbers with numbers. In doing so you must be sure to change the sign of the term if it is passed from one side to the other.

In this case it would be:

4x + 7x + 1 < 11x + 2

(Four plus seven is 11)

11x + 1 < 11x + 2

We can see that x is eliminated, because we change the sign on 11 to be -11:

11x - 11x + 1 < 2

1 < 2

This result means that no matter which value we give to x, the inequality will be always true. For that reason the answer is all real numbers
