Explain the benefits of the steam engine and the transcontinental railroad.

The steam engine is the name given to any engine that operates by transforming thermal energy into mechanical energy by expanding water vapor. Developed in the eighteenth century, its technology continued to be used and refined until the early twentieth century.  

The First Transcontinental Railroad is the first rail line in the United States that has allowed rail transport, ie, the transportation of goods through locomotives.

Both the steam engine and the transcontinental railroad offered various advantages to traders and the general population. That's because the steam engine and the transcontinental railroad provided cheap and fast transportation, getting goods to the right place quickly and for a very low price. In addition to the low cost of transport, the volume of trade, that is, the market, has increased even more. Increased trade made it necessary to produce more, and thus the advances of industrialization became ever greater.

b. major john c. frémont led a rebellion called the bear flag revolt.

explanation:

during the bear flag revolt, from june to july 1846, a small group of american settlers in california rebelled against the mexican government and proclaimed california an independent republic. the republic was short-lived because soon after the bear flag was raised, the u.s. military began occupying california, which went on to join the union in 1850. the bear flag became the official state flag in 1911.

part a. there were 250 teenagers surveyed (100% of tenagers = 250)therefore 1 % = 250/100 = 2.5 76% = 1% x 76 = 2.5 x 76 = 190 teenagers of the 250 surveyed liked burgerspart b: jane surveyed 25% (which is equal to 50 teenagers, i.e. a quarter of the teenagers surveyed is 50) to get 100% we simply get 4 quarters, i.e. multiply 50 by 4 = 200 teenagers were surveyed by jane. part c: it is impossible to give an example where a percentage is greater than 100%, since, by definition , percentage means "per 100".
