chemistry. * To express a number in scientific notation‚ you must move the decimal point as many places to the right or left depending if the number is less than or more than zero‚ until only one digit remains at the left of the decimal point. Then drop all the zeroes to the right of the decimal point (except if it is between two non-zero digits) and multiply it to 10 to the power of n‚ the number of places the decimal point moved‚ negative when going to the right‚ and positive when going to the

General Computer Questions [pic] General Computer Question 1: What is a computer? Answer: A common‚ somewhat simplified‚ definition is that the computer is an electronic device that can be used to process information. Today‚ computers are not only used for calculations‚ but also for creating and manipulating text and pictures. They are used to design bridges and spacecraft‚ to record a company’s sales and to keep track of customers‚ to create a school newspaper‚ or to estimate the cost

each color. (To find percent of a certain color‚ take the number of M&M’s of that color and divide that by the total number of M&M’s in the bag.) when you do the math‚ you will get a decimal. Move the decimal two (2) places to the right to convert to a percentage. Round to one place after the decimal. Record your results in the data table in the row of your group’s data.

Task One: Gather‚ present and interpret data for a purpose The purpose of my task is to compare daily website traffic to the daily sales conversion rate over the month of June for a newly established sales campaign. With this information I can identify whether the projected conversion rate percentage has been forecast accurately. This information will also be used as the control sample data to base future sale trends on. w/c |Visitors / Sales |Mon |Tues |Wed |Thurs |Fri |Sat |Sun |Week Total

223. How many usable hosts? To determine the number of usable hosts‚ use the formula (i.e.). Subnet Mask – CIDR The subnet determines how many subnets a network will have and‚ consequently‚ how many hosts each subnet will have. The mask‚ when in binary form‚ will display the bits in 1s and 0s respectively. Those bits that are 1s are considered network/subnet bits‚ and those bits that are 0s are considered host bits. When determining how many subnets will be created from a specific mask‚ consideration

Date | Event | c. 2400 BC | The abacus - the first known calculator‚ was probably invented by the Babylonians as an aid to simple arithmetic around this time period. This laid the foundations for positional notation and later computing developments. | 1300 | Ramon Llull invented the Lullian Circle: a notional machine for calculating answers to philosophical questions (in this case‚ to do with Christianity) via logical combinatorics. This idea was taken up by Leibniz centuries later‚ and is thus

232g/mol) = 227.1g/mol (Actinium) 2. Calculate the approximate percent abundance of gallium’s isotopes (69Ga‚ 71Ga) in a sample of gallium metal. Ga atomic mass is 69.72g/mol. Let x be the % of 69Ga as a decimal and therefore 1.000 – x is the % of 71Ga as a decimal. (x)69 + (1.00 – x)71 = 69.72 69x + (71.00 – 71x) = 69.72 71.00 – 2x = 69.72 71.00 – 69.72 = 1.28 = 2x x = 1.28/2 = 0.64 or 64%‚ 69Ga = 64% 1.00 – x = 1.00 – 0.64 = 0.36 or 36%‚ 71Ga = 36%
