Six xerox machines can copy 30000 sheets in 5 days How many machines are needed to recopy 30000 sheets in 10 days?

3 machines. You can see this easily by saying 6 machines copy 30,000 sheets in 5 days, so 1 machine must copy 5,000 sheets in 5 days. If we want to make 30,000 sheets in 10 days, that means we want to make 15,000 sheets in 5 days. If 1 machine makes 5,000 sheets in 5 days, then we need 3 machines to make 15,000 sheets in 5 days, and 3 machines to make 30,000 sheets in 10 days. So we need 3 machines. Hope this helps!


Eight workers can build a cabin in 60 hours. How many workers are needed if the cabin is to be built in 32 hours?

To determine how many workers are needed to build the cabin in 32 hours, we can use the formula: (workers) x (time) = constant. In this case, the constant is the same amount of work needed to build the cabin. So, 8 workers x 60 hours = 480 worker-hours. To build the cabin in 32 hours, we divide the constant (480 worker-hours) by the new time (32 hours) to find that 15 workers are needed to build the cabin in 32 hours.

Foundry Worker?

Foundry workers are employed in the manufacturing industry and work operating the machines that make metal and plastic components for a variety of different industries, companies, and products. Foundry workers are generally divided into machine setters who setup machines to be used, and machine tenders who actually operate the devices. As there are many different items and components to be made, machines are configurable depending on the specifications for a particular product. The setter get the machine ready by installing the specific tools that are to be used for the machine, prepares materials, and inspects machine equipment prior to use. After the setter has readied a machine, an operator will continually load it with materials as it produces, monitor it, and adjust production speeds as needed to ensure it is functioning properly. There are many different types of machines that may be be used by foundry workers, including milling machines, turning machines, and planing machines. The more machines a foundry worker is trained to use properly, the more flexible they can be in work hours, schedule, and future job prospects within a company. The work environment for a foundry worker is that of a clean, well maintained, factory based setting. Due to the nature of the work, safety and precaution is the number one priority at all times for foundry workers. As a result, foundry workers must wear safety equipment such as hard harts, ear plugs, safety goggles, and steel toed boots. The work week is usually 40 hours, but there is often overtime available. It is required by most companies for foundry workers to have at least a high school diploma. All of the skills and knowledge needed for the job will be taught with hands on, supervised, on the job training. Salary for foundry workers varies depends on the company, skill level, and years experience of an individual. Additionally, the type of industry influences wages, as well as the machines that are being operated. There is also the possibility that the workers of a particular company are unionized, which can affect worker salary. The range for foundry workers salary is from $13.54 per hour to $19.55 per hour, on average.
