  1. KATE I CHAD H CAITLIN S UNIT 3 GROUP PROJECT

  2. OBJECTIVE ONE • SAMPLE PROBLEM • Take -1+5=6x2 =

  3. OBJECTIVE ONE • 1) • 2) • 3 • PRACTICE PROBLEMS Answers: 1) 60 2) 80 3) 36

  4. OBJECTIVE TWO • SAMPLE PROBLEM • WRITE NUMBERS IN DECIMAL NOTATION IN SCIENIFIC NOTATION • 4,120,000,000 • SCIENTIFIC NOTATION CAN NEVER HAVE A NUJMBER GREATER THAN 9. SO IN ORDER TO PUT IT IN S.N. , YOU HAVE TO MOVE THE DECIMAL PLACE TO THE LEFT UNTIL THE NUMBER IS LESS THAN 9. COUNT YOUR DECIMAL JUMPS-AND THAT’S THE POWER YOU PUT ON YOUR NUMBER. • SO 4,120,000,000 = 4.12⁹

  5. OBJECTIVE TWO • PRACTICE PROBLEMS • 1. 6,13000000000000 = 6.13 E. 14 • 2. 9,1600000 = 9.16 E. 7 • 3. 7,960000000000 = 7.96 E. 12

  6. OBJECTIVE THREE Sample problem: 7.23x10⁻3(note that the 3 should be superscript) =0.00723

  7. OBJECTIVE THREE • PRACTICE PROBLEMS Problem 1: 6.72x10⁷= 67,200,000 Problem 2: 3.56x10⁻⁴= 0.000356 Problem 3: 9.21x10⁹=9,210,000,000

  8. OBJECTIVE FOUR • Sample problem: • 0.356 miles = ____Feet • 5280 feet= mile so take 0.356 divided by 5280 and you get 6.7 feet

  9. OBJECTIVE FOUR • PRACTICE PROBLEMS • 8000 feet= ____ miles • 7000 miles=_____feet • 5280 feet= _____miles

  10. OBJECTIVE FIVE • SAMPLE PROBLEM • CONVERT WITHIN UNIT IN THE METRIC SYSTEM OF MEASUREMENT • 5.6G=______MG. THE METRIC SYSTEM HAS PREFIXES THAT GO ON THE BEGINNING OF THE SYSTEM OF MEASUREMENT. KILO,HECTA, DEKA, UNITS, DECI, CENTI, MILLI. IF THE UNTI IS GRAMS AND YOU ARE TRYING TOGET TO MILLIGRAMSM JUST MOVE THE DECIMAL THE WAY THE METRIC “PREFIX LINE” GOES. SO 5.6G=560MG

  11. OBJECTIVE FIVE • PRACTICE PROBLEMS • 1. 65KG = 600G • 2. 7ML=.000007KL • 3. 9MM=.000009KM

  12. OBJECTIVE SIX • Sample Problem: what is the best metric for measuring the height of the door: km, m, cm, mm?

  13. OBJECTIVE SIX • PRACTICE PROBLEMS • Problem 1: what is the best metric for measuring the diameter of a garbage can: km, m, cm, mm? • Problem 2: “ “ area of a dumpster: m squared, km squared, cm 2’d, ha? • Problem 3: height of the curb: cm, mm, m, km

  14. OBJECTIVE SEVEN • SAMPLE PROBLEM • 325,000 =______ • Refer to gold sheet

  15. OBJECIVE SEVEN • PRACTICE PROBLEMS 1 2 3 Answers: 1: 27 2: 16.39 3: 10,000

  16. OBJECTIVE EIGHT • SAMPLE PROBLEM • CONVERT TEMPLERATURE AND TIME • HOW MANY SECONDS ARE IN 3 DAYS, 8 HOURS, 21 MINUTES, AND 42 SECONDS • FIRST, YOU HAVE TO MAKE A TABLE. THEN, YOU FILL IN THE SPOTS WITH DAYSM HOURS, AND MINUTES. • 3D 24H 60M 60S • 1D 1H 1M THEN, YOU MULTIPLY ACROSS THE TABLE. • YOUR MATH SHOULD LOOK LIKE THIS: 3*24=72 72+8=80 80*60=4800 4800*60=288000SEC. 21*60=1260 1260+42=1302 288000+1302=289302 • 289302 SECONDS IN 3 DAYS, 8 HOURS, 21 MINUTES, AND 42 SECONDS

  17. OBJECTIVE EIGHT • PRACTICE PROBLEMS • 1. 2 DAYS, 1 HOUR, 3MINUTES, AND 58 SECONDS = 176638 SECONDS • 2. 4 DAYS, 7 HOURS, 20 MINUTES, 41 SECONDS 372041 SECONDS • 3. 1 DAY, 9 HOURS, 19 MINUTES, 9 SECONDS= 121749 SECONDS

  18. OBJECTIVE NINE • Sample Problem: 10⁰C = • Problem 1: 112⁰F= • Problem 2: -20⁰C= • Problem 3: 23⁰C=

  19. OBJECTIVE NINE • Answers • Sample problem: 50⁰F • Problem 1: 44.4⁰C • Problem 2: -4⁰F • Problem 3: 73.4⁰F

  20. OBJECTIVE TEN • SAMPLE PROBLEM • 12 mi=______km • Answer: 15.54 • Use gold sheet

  21. OBJECTIVE TEN • PRACTICE PROBLEMS • 1 • 2 • Answer: 1: 10,000 2: 8361
