The benefit of the transcontinental railroad was that it ended many risks of traveling across the country.
<h3>Why was the transcontinental railroad created?</h3>
The American railroad, was created in 1869, with an important innovation through the connection between the coasts of the Atlantic and Pacific oceans, having as benefits the expansion of commercial and passenger transport routes in America.
Therefore, the transcontinental railroad was built using mechanized technology in the 19th century, increasing the safety and speed of travel.

Do you need help or are you telling?
Answer:
C) there is at least one fixed factor of production.
<u>Multiple-choice options</u>
A) there is increasing scarcity of factors of production.
B) the price of extra units of a factor is increasing.
C) there is at least one fixed factor of production.
D) capital is a variable input.
Explanation:
he law of diminishing marginal returns cites that adding extra input while maintaining the others fixed will cause the overall output to decrease . Adding one more production input while keeping the rest intact decreases the marginal returns and increases the average production cost.
The law only applies where there at least one fixed input. When the firm uses more of the variable input, the firm's marginal product will eventually decrease.
Solution:
Given Information,
Heat input is ( 
) = 5.5 × 
Btu/h
Combustion efficiency of the boiler (
) = 0.7
Combustion efficiency after turn up (
) = 0.8
Operation Hour (t) = 5200h
Unit cost (c) = 
Calculate heat output from the boiler 
= x
= 5.5 x x 0.7
= 3.85 x Btu/h
Calculate the heat input to the boiler after the tune-up
= / 
= 3.85 x / 0.8
= 4.8125 x Btu/h
Calculate the saved energy after the tune-up
= -
= 5.5 x - 4.8125 x Btu/h
= 0.6875 x Btu/h
Calculate the annual energy saving ( 
)
= x t
= ( 0.6875 x Btu/h ) ( 5200 hr/yr)
= 3575 x Btu/h
Calculate the annual cost saving
Annual cost saving = 
x Unit cost
= 3575 x Btu/h x
= 82225
