The number of class tickets she did buy is 3. The number of coach tickets she did buy is 8.
What are tickets?Tickets are a piece of paper that contains all the information for someone to enter somewhere or travel.
x= number of coach tickets and y = number of first-class tickets.
$210x + $1200y = $10,230 (cost of a coach ticket plus the cost of first-class tickets is the total budget)
The second equation for y to get y = 11 - x, then plug that into the first equation and solve for x:
$210x + $1200(11 - x) = $10,230
$210x + $13,200 - $1200x = $10,230
-$990x + $13,200 = $10,230
-$990x = $2,970
x = 3
Sarah bought x = 3 coach tickets. The seconds equation and solves for y:
3 + y = 11
y = 8
Thus, the class tickets she did buy are 3 and the coach tickets are 8.

Primary power is the electrical supply from the power company.
False
True
Primary power is the electrical supply from the power company. The given statement is True.
How do main and secondary powers differ?Primary distribution lines, often known as primaries, are those located on the high voltage side of the distribution transformer. Secondary distribution lines, or secondaries, are those found on the low-voltage side of the distribution transformer. Primary energy (PE) is a type of energy that can be found in nature that hasn't undergone any artificially designed conversion procedures. It is the energy that is present in unprocessed fuels and other energy sources, such as trash, that are introduced into a system.
Renewable or nonrenewable sources can be used for primary energy. Primary energy sources come in a variety of shapes and sizes, and they can be either nuclear, fossil (such as coal, oil, and natural gas), or renewable (such as wind, solar, geothermal, and hydropower).

How do engineers deal with liquefaction when building a very tall building?
Answer:
Engineers can use a variety of techniques to prevent or mitigate the effects of liquefaction when building a very tall building. Liquefaction is a phenomenon that occurs when soil loses its strength and stiffness due to increased pore water pressure. This can cause the ground to become unstable, potentially leading to significant damage to buildings and other structures. To prevent liquefaction, engineers may use a combination of techniques, including:

Explanation:
The wind is an actual form of solar energy. winds are caused by the heating of the atmosphere by the sun, the rotation of the earth, and the earth's surface irregularities. The wind is capture in a wind turbine which provides a renewable energy source, the wind makes the rotor spin, as the rotor spins the movement of the blades drives a generator that creates energy, also known as wind power. The average wind efficiency of turbines is between 35-45%.
Advantages of wind power
- Wind power is cost-effective
- wind creates jobs
- wind enables US industry growth and US competitiveness
-it's a clean fuel source
At the operations level of industrial internet what is not critical
At the industrial internet's operational level, Time is not crucial.
Explain about the industrial internet?An interconnected system of sensors, instruments, and other devices is referred to as the "industrial internet of things" and is utilized in industrial computer applications such as production and energy management.
Increased efficiency The main benefit of IIOT is the ability for industries to automate and increase their operational efficiency. Robotics and automated machinery can work more accurately and effectively, improving output and helping businesses streamline their processes.
Due to its emphasis on machine-to-machine (M2M) connectivity, big data, and machine learning, the IIOT enables businesses and industries to function more effectively and dependably.
Examples of IIOT devices in an IIOT network include sensors, computers, and machinery used in manufacturing, agriculture, and mission-critical applications, such as nuclear and energy management systems.

describe 3 examples of biases in design
As we mature, we come to understand that not everything should be perceived and thought of in the same manner. The design term for this is “bias.” increasing awareness and preventing ourselves or our organizations from being victims of such bias.
What are the biases in design?Confirmation bias, sampling bias, and brilliance prejudice are three examples of biases that might affect our ability to objectively assess information.
To help us better grasp how cognitive biases affect our daily life, Jono Hey of Sketchplanations talks us through some examples.

This is for a history assignment, but it is an engineering question: How long is the length, width, and height of an average power plant?
The length, width, and height of an average power plant varies. The size of a power plant can vary greatly depending on the type of technology it uses and the amount of power it generates.
Some power plants, such as hydroelectric dams, can be very large and span several kilometers in length. Other types of power plants, such as natural gas or coal-fired plants, are typically smaller and may only be a few hundred meters in length.
What is the power plant size about?The size of a power plant may also depend on the location in which it is built. For example, a power plant built in a dense urban area may be smaller in size due to space constraints, while a power plant built in a more rural area may be larger to take advantage of available land.
In terms of the height of a power plant, again this can vary greatly depending on the type of technology being used. Some power plants, such as nuclear or coal-fired plants, may have tall smokestacks that are several hundred meters tall.
Therefore, Other types of power plants, such as solar or wind farms, may have much shorter structures, as they do not require the same type of large equipment.

Carolina wants to determine which services are running on the Linux servers in a certain subnet. Which of the following tools would best perform this task?
a. nmap
b. ifconfig
c. telnet
d. ping
Answer: nmap
Explanation:
The best tool to use for determining which services are running on Linux servers in a certain subnet is nmap. Nmap (short for "Network Mapper") is a network scanning and security tool that can be used to discover and map networks, as well as to identify the services that are running on specific servers or devices.
Nmap can be used to scan a subnet and identify the hosts and devices that are connected to it, as well as to determine the services that are running on those devices. This can be useful for identifying potential vulnerabilities or security risks, as well as for understanding the network and its capabilities.
In contrast, the other options listed (ifconfig, telnet, and ping) are not as well-suited to the task of determining which services are running on Linux servers in a subnet. Ifconfig is a command-line utility that is used to configure network interfaces, but it does not provide information about services running on servers. Telnet is a protocol for connecting to remote servers, but it does not provide information about the services that are running on those servers. Finally, ping is a tool for testing network connectivity, but it does not provide information about services running on servers.
