Question

7. Given that 1 kilometer - 0.62 1 kilometer - 0,62 mile, 36 inches = 1 yard, and 1 mile = 1760 yards, approximately how many inches are in 8. Given that the average pulse is 70 heartbeats per minute, determine the number of heartbeats per lifetime of a person whose life expectancy is 80 years. The average number of words per page for a Microsoft Word document formatted with default margins and a 12-point Times New Roman font is 260. Estimate the number of pages needed for a 10,000-word document. 10. Changing the font to 14-point Times New Roman reduces the average number of words per page by approximately 8%. Estimate the number of pages needed for a 10,000-word document using this larger font (refer to Exercise 9). 11. Changing the side margins from 1.25" to 1" increases the average num- ber of words per page by approximately 15% when 12-point Times New Roman is used. Estimate the number of pages needed for a 10,000-word document using these narrower margins (refer to Exercise 9). 12. The average number of words per page for a Microsoft Word document for matted with the default margins and 12-point Arial is 245. Estimate the number of pages needed for a 10,000-word document. 13. An instructor assigns you a 12-page paper and specifies a 12-point font and default margins. Approximately how many fewer words would you need to type if you used Arial instead of Times New Roman (refer to Exercises 9 and 12)? 14. When we computed the absolute error in Section 1.5, the units were significant. When we computed relative error, there were no units, Explain why this occurs.

Answer 1

1)

1 KM=0.62*36*1760 inches=39283.2 inches

2)

Minutes in 1 year are 525600

So, Heartbeats are 525600*70*80=2943360000 heartbeats
