When we look back at our definition of equivalent decimals, it says that two decimals are equivalent when they name the same value (or same amount). By showing that 0.3 and 0.30 cover the same space, we have just proven that these two decimals are, in fact, equivalent!
The Aztecs were a Pre-Columbian Mesoamerican people of central Mexico in the 14th, 15th and 16th centuries.They called themselves Mexica (pronounced [meËÊikaÊ]).The Republic of Mexico and its capital, Mexico City, derive their names from the word Mexica. The capital of the Aztec empire was Tenochtitlan, built on a raised island in Lake Texcoco.rom 1376 until 1427, the Mexica were a tributary of Azcapotzalco. The Aztec rulers Acamapichtli, Huitzilihuitl and Chimalpopoca were, in fact, vassals of Tezozomoc, the Tepanec ruler of Azcapotzalco.
The ancestors of the Aztecs settled on a marshy island in Lake Texcoco in either 1325 or 1345. According to legend the Aztecs settled at a place where they saw an eagle perched on a cactus with a snake in its mouth. They took this as a sign from their god that they should settle there.he Aztecs called the place Tenochtitlan, which means place of the cactus. At first they were an unimportant people but in the 15th century the Aztecs gradually built up a large empire. However the Aztec empire was not an 'empire' like the Roman Empire, which was ruled from one city.
