How, for example, is a mathematical model MOST useful to the work of a civil engineer? (1 point) Responses A mathematical model can make predictions. A mathematical model can make predictions. A mathematical model can calculate salaries. A mathematical model can calculate salaries. A mathematical model can impress clients. A mathematical model can impress clients. A mathematical model can potentially be inaccurate. A mathematical model can potentially be inaccurate.

Answer 1

The most useful response to how a mathematical model is useful to the work of a civil engineer is:

"A mathematical model can make predictions."

This is because mathematical models are often used in civil engineering to predict the behavior of structures, analyze stresses and strains, optimize designs, and simulate various conditions, which is essential for effective planning and construction.

Answer 2

Some cities, no matter when they were founded or where they are located, seem to be easier to navigate. Chicago is built on a grid system so a traveller, even without GPS, can easily find an address. What type of engineering helps create such a system? (1 point) Responses structural structural construction construction geotechnical geotechnical urban

Answer 3

The type of engineering that helps create a navigable grid system like that in Chicago is:

urban engineering.

Urban engineering focuses on the design and development of urban infrastructure, including transportation systems, land use, and city layouts, which are essential for creating efficient and easily navigable cities.

Answer 4

What descriptive term BEST describes civil engineering? (1 point) Responses projects on land projects on land 20th century discipline 20th century discipline projects and systems projects and systems private sector

Answer 5

The descriptive term that BEST describes civil engineering is:

projects and systems.

Civil engineering encompasses a wide range of projects related to the design, construction, and maintenance of infrastructure systems, such as roads, bridges, buildings, and water supply systems.

22.On a job site, surveyors Isolde and Leah use both an advanced computerized system and some simple tools. For example, when they need to orient a line directionally, what tool would they MOST likely use? (1 point) Responses a mirror a mirror a timer a timer a level a level a compass.

23.Civil engineering projects include a huge variety of old and new structures; including, bridges, shopping malls, power plants, sewage systems, and skyscrapers. When might the work of a civil engineer be needed for a residential house? (1 point) Responses when it is extremely large when it is extremely large when it is located on a difficult site when it is located on a difficult site when it is a public structure when it is a public structure when a generous budget allows when a generous budget allows

24.Rieka, working on improving an air filtering system, suspects that the rate of airflow from one part of the system to another can be increased. Energy specifications can be upgraded but need to stay within a safe range to prevent materials failure. What is the MOST practical way Rieka can test the components? (1 point) Responses reverse engineer the system by dismantling the entire original product reverse engineer the system by dismantling the entire original product build models of the two parts and test their soundness at different flow speeds build models of the two parts and test their soundness at different flow speeds use a simulation program to try filtration components from various manufacturers use a simulation program to try filtration components from various manufacturers sketch the system, highlighting the parts that are affected and need to change sketch the system, highlighting the parts that are affected and need to change

25.How is a scale model different from other types of models? (1 point) Responses It is made with appropriate materials. It is made with appropriate materials. It represents the consolidated ideas of a group. It represents the consolidated ideas of a group. It maintains correct spatial relationships. It maintains correct spatial relationships. It is the last model created in the design process.
