Answer:
Hello there! There are 4 parts to this question, all regarding relational database concepts.
Explanation:
Parts 1, 2, 3, 4 are drawn in attachments. For Part 4, the "foreign keys" would be the id fields of the joining table, and the "primary keys" are the IDs of the table itself. Data types are "integer" for ID, "string" for text columns like Name and Location, and "Decimal" for Hourly rate in the Timesheet table. Note that we can further simplify the erd from the one constructed earlier in part 3 to remove the Project Manager model and instead add a Project Manager "boolean" flag in the Employee table since a Project Manager is also an Employee.

Answer: B) Install an addition memory card to the current drive
Explanation: Drive storage space is space that has particular capacity to store files and data. If the storage reaches the capacity,it turns out that more space is required for the data storage. The hard drive is a major storage space in a system with large capacity. So, if it gets full, there are various ways it could be increased such as replacing it with other internal hard drive, external hard drive etc.
But installation of the memory card is not the solution for increasing the space because they don't have very large space and can only support small devices.
Automobile repair shops produce many types of waste -- some hazardous, some not necessarily hazardous but still potentially damaging to the environment if not handled properly, and all requiring proper treatment and/or disposal at significant cost to the business. A list of the types of waste that the shop owner or manager must contend with would include:
solvents (paints and paint thinners)
antifreeze
scrap metal
batteries and other auto parts
oils and oil filters
fuels of various types
acids and alkalis (contaminated rags and towels)
Whatever the nature and characteristics of the waste may be, it all has one thing in common: All waste represents loss of resources and loss of money.
