1 century = 100 years → you know that 1 year = 52 weeks 1 century = 100 * 52 weeks 1 century = 5200 weeks 1 century = 5200 weeks x century = 13 weeks You make the cross-multiply, and you get: 5200x = 13 x = 13/5200 → you simplify by 13 x = 1/400 13 weeks represent a fraction of 1/400 of century.
1 decade = 10 yearssince 100 years = 1 century then1 decade =1/10 century========================Algorithms / Methods of Procedure:-- To get years, multiply decades by 10.-- To get centuries, divide decades by 10.
The Chinese were the first to use decimals. Decimals were developed and used in the 1st century B.C. in China and then spread to the Middle East and Europe.
The number system that we use today is called the Hindu-Arabic system and it originated in India in the 6th or 7th century.
Here are the steps to solve that: * Take the last year of the 20th century (that would be 2000). * Divide that by 37. * Round the result downwards, to the nearest integer. That is, simply eliminate everything after the decimal point. * Multiply the result by 37.
Charles Babbage is considered the father of the computer. He created the first mechanical prototype in the early 19th century.
The first calculating machine that included the concepts of a modern computer (data storage, programming, I/O) was the Difference Engine, conceived by Charles Babbage in the mid-19th century. It was never fully constructed because the metallurgy of the time did not permit exact enough casting and machining for it to work accurately. A 20th-century effort to reproduce Babbage's work using modern metalworking techniques showed that his Engine was in fact practical. Many companies developed and sold functional mechanical calculators in the 19th century. However they did nothing but add, subtract, multiply and divide, and could not store data or programs. As technology developed in the mid-20th century these firms moved into computers, but their calculators were not truly "ancestors" in the sense that their functions did not evolve into computers. Instead these firms stopped building mechanical calculators and began building computers as a separate line of business.
The calender was developed in the 8th Century by the Mayans.
No, the very first mechanical calculators could only add and subtract. The first mechanical calculators were invented in 1623 by Wilhelm Schickard, followed by the Pascaline, invented in 1645 by Blaise Pascal. However, calculators that could multiply and divide were in use by the 19th century.
Melodrama was developed in the 18th century
The novel that began with William Dean Howells in the nineteenth century and had been further developed in this century is Years of My Youth.
20th Century
The first modern-style electronic calculator was invented in the 1960s. The first counting device, an abacus, was invented in Egypt in about 2000 BCE. The mechanical calculator was developed in the 17th century.
Chinese developed gunpowder in the 9th century.Chinese also developed the compass between the 2nd century BC and 1st century AD.
During the early modern period of the twentieth century, the synthesizer was developed.
James Joule worked in Manchester, England, where he conducted his experiments on the nature of heat and developed the concept of mechanical equivalent of heat. He was a brewer by trade and conducted his groundbreaking research in the 19th century.
