10. Given that 1 nautical mile = 6080 feet and that 1 foot = 12 inches, what is the approximate scale ratio (in the same units) of a chart which has a stated scale of 2 inches = 25 nautical miles? Answer 1:250 000 1:3 648 000 1:912 000 1:1 824 000 11. Referring to the equation, P1 x V1 = P2 x V2, if P1 and V1 remain constant, whilst P2 increases, how is this relative to V2? Answer Inversely proportional Reversely proportional Directly proportional Sequentially proportional

Electronic Spreadsheet

Tabular listing has many advantages ranging from time management to efficient scheduling of tasks. Electronic spreadsheets allow the user to tabulate and analyze data, using its easy-to-use interface. An electronic spreadsheet is a staple application used among accountants, management staff, and IT professionals. It is used in various sectors worldwide for data management. An electronic spreadsheet is a system and computer software that could be used to do numerical computations automatically. Spreadsheet application programs are often organized as a table with rows and columns. Each row and column intersect to form a cell, which may be used to store data. These data can take the form of a written label, a number, or a formula that combines information from other cells.
