PART III: REVIEW FOR THE WRITTEN EXAMINATION PDF417 Encoder In Visual Studio .NET Using Barcode encoder for .NET framework Control to generate, create PDF417 image in .NET framework applications. Reading PDF 417 In VS .NET Using Barcode scanner for .NET framework Control to read, scan read, scan image in .NET framework applications. the apparatus in 20 minutes How long would Clay need to wash the re apparatus by himself
Create Barcode In VS .NET Using Barcode encoder for .NET framework Control to generate, create bar code image in .NET framework applications. Bar Code Decoder In VS .NET Using Barcode scanner for VS .NET Control to read, scan read, scan image in Visual Studio .NET applications. Note: Use the formula W (Work done) = r (rate) t (time) Basiclevel work problems usually have W equal to 1 PDF 417 Printer In Visual C# Using Barcode maker for .NET framework Control to generate, create PDF 417 image in .NET applications. PDF417 2d Barcode Creator In .NET Using Barcode creation for ASP.NET Control to generate, create PDF417 2d barcode image in ASP.NET applications. Therefore W W __ W= r t and _r = t ___ = r t Let W = 1 (job of washing the re apparatus) 1 ___ = rate at which Randy performs the work 60 1 ___ = rate at which both Randy and Clay perform the work 20 1 __ = rate at which Clay performs the work t Therefore 60 t 20 1 1 1 (60t) ___ + (60t) _t_ = (60t) ___ 20 60 t + 60 = 3t 60 = 2t 30 = t number of minutes Clay needs to wash the re apparatus by himself 1 1 1 ___ + __ = ___ nd LCD = 60t multiply each term by LCD (60t) bring the variable over to one side of the equation PDF417 Creation In VB.NET Using Barcode creator for .NET framework Control to generate, create PDF417 image in VS .NET applications. Code39 Generator In .NET Using Barcode printer for Visual Studio .NET Control to generate, create Code39 image in VS .NET applications. DISTANCE, RATE, AND TIME PROBLEMS
Paint Bar Code In .NET Framework Using Barcode generator for .NET framework Control to generate, create barcode image in .NET framework applications. GS1 DataBar Truncated Encoder In VS .NET Using Barcode printer for Visual Studio .NET Control to generate, create GS1 DataBar Stacked image in Visual Studio .NET applications. When we look at the relationship between distance (d), rate (r), and time (t), we can use the formula: d = r t to nd the answer not only for distance but for rate of speed and time as well d d __ = r; __ = t d=rt and r t Matrix Barcode Encoder In VS .NET Using Barcode printer for VS .NET Control to generate, create Matrix Barcode image in .NET framework applications. Creating Uniform Symbology Specification Codabar In VS .NET Using Barcode encoder for .NET Control to generate, create Rationalized Codabar image in Visual Studio .NET applications. Note: If in a word problem, parts of the trip are at different rates of speed, then to nd the total time or total distance you must separate the parts of the trip Making UCC  12 In ObjectiveC Using Barcode encoder for iPhone Control to generate, create GS1  12 image in iPhone applications. Generate UPC  13 In Java Using Barcode printer for Java Control to generate, create GTIN  13 image in Java applications. Example: A plane can y at a rate of 400 miles per hour (mph) from point A to point B, a distance of 1600 miles A highspeed train, however, makes the same trip back from point B to point A at a rate of speed of 160 mph How many hours was the whole trip to and from points A and B (d) (t) = ___ (r) (t) going = 1600 miles 400 mph = 4 hours (t) returning = 1600 miles 160mph = 10 hours Total (t) of whole trip = 14 hours Example: A man can walk 4 mph in a still wind When a favorable wind is at his back he can walk 15 miles in 3 hours How fast is the wind UPC  13 Printer In C#.NET Using Barcode drawer for .NET framework Control to generate, create EAN13 image in Visual Studio .NET applications. EAN / UCC  14 Encoder In None Using Barcode creator for Software Control to generate, create GS1 128 image in Software applications. CHAP 7: MATHEMATICS
GS1  12 Drawer In .NET Using Barcode generation for ASP.NET Control to generate, create UCC  12 image in ASP.NET applications. EAN13 Supplement 5 Printer In Java Using Barcode creation for BIRT Control to generate, create EAN13 image in BIRT reports applications. Note: Use the formula: d = r t
Generate Data Matrix ECC200 In Visual Studio .NET Using Barcode creator for Reporting Service Control to generate, create Data Matrix image in Reporting Service applications. Making UPC  13 In Visual Studio .NET Using Barcode generator for ASP.NET Control to generate, create GTIN  13 image in ASP.NET applications. (r) = wind speed (r + 4) = speed walking with wind at his back 15 miles = (r + 4) (3hours) = 3r + 12 15 = 3r + 12 3 = 3r 1 mph = r Example: An automobile travels through an intersection going north at 30 mph Ten minutes later, a second automobile passes through the same intersection traveling in the same direction going 60 mph How long will it take for the second automobile to overtake the rst automobile Note: Use the formula: d = r t
(10 minutes) Let the rst automobile = (30 mph) ___________ 10 minute head start (60 minutes) at 30 mph 1 (30) __ = 5 miles traveled prior to second automobile 6 reaching same intersection The second automobile is gaining at a rate of 60 mph 30 mph = 30 mph How long (t) will the second automobile gaining at a rate (r) of 30 mph take to cover the (d) 5 mile head start of the rst automobile d=r t 5 = 30 (t) Divide both sides of the equation by 30 1 __ = t 6 1 of an hour = 10 minutes = t = time required for the second automobile __ 6 to overtake the rst automobile Example: Two trains pass in the night One train is traveling west at 60 mph while the second train is going east at 80 mph When will the trains be 420 miles apart Note: Use the formula: d = r t Note: When objects are moving in opposite directions, regardless of whether the objects are moving towards each other or away from each other, the rate at which the distance between them is changing is the sum of their individual rates Therefore: 60 mph + 80 mph = 140 mph Let t = number of hours the trains will travel after passing each other 420 miles = 140 mph t 420 miles _________ = t divide by 140 on both sides of the equation to isolate 140 mph the variable
