How did railroad companies profit from the building of the trans continental rail road? a by selling railroad signs. b by renting land to settlers c by selling advance tickets to settlers who plant to move west. d by selling their own government

answer: beginning in the early 1870s, railroad construction in the united states increased dramatically. prior to 1871, approximately 45,000 miles of track had been laid. between 1871 and 1900, another 170,000 miles were added to the nation's growing railroad system. much of the growth can be attributed to the building of the transcontinental railroads. in 1862, congress passed the pacific railway act, which authorized the construction of a transcontinental railroad. the first such railroad was completed on may 10, 1869. by 1900, four additional transcontinental railroads connected the eastern states with the pacific coast.

explanation:

the correct answer is:   "   3.6 % " .

          →   the unemployment rate is:   " 3.6 % " .

explanation:

to calculate the "unemployment rate" :

the "unemployment rate"   =

  [# of people unemployed] /   [working age population]   * 100 %   ;

                =   [9 million] / [250 million]     *   100 % ;

    →     note:   the units of "million" cancel out;

                    since:   " {million} / {million} = 1 " ;

                =   (9 / 250)   * 100 %   ;

                = 0.036 * 100 % ;

                =   3.6 %

answer:   the unemployment rate is:   " 3.6 % " .
