KATE I CHAD H CAITLIN S UNIT 3 GROUP PROJECT OBJECTIVE ONE SAMPLE PROBLEM Take -1+5=6x2 = 10 12 2 1 10 10 5 OBJECTIVE ONE PRACTICE PROBLEMS 1) 2) 10 10 3 9 10 10 10 8 3 5 10 10 5 7 3 Answers: 1) 60 2) 80 3) 36 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 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 OBJECTIVE THREE Sample problem: 7.23x10⁻3(note that the 3 should be superscript) =0.00723 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 OBJECTIVE FOUR Sample problem: 0.356 miles = ____Feet 5280 feet= mile so take 0.356 divided by 5280 and you get 6.7 feet OBJECTIVE FOUR PRACTICE PROBLEMS 8000 feet= ____ miles 7000 miles=_____feet 5280 feet= _____miles 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 OBJECTIVE FIVE PRACTICE PROBLEMS 1. 65KG = 600G 2. 7ML=.000007KL 3. 9MM=.000009KM OBJECTIVE SIX Sample Problem: what is the best metric for measuring the height of the door: km, m, cm, mm? 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 OBJECTIVE SEVEN SAMPLE PROBLEM 325,000 cm 3 =______ m 3 Refer to gold sheet OBJECIVE SEVEN PRACTICE PROBLEMS 1 2 3 yd 3 ____ ft 3 in 3 _____ cm3 ha _____ m 2 Answers: 1: 27 2: 16.39 3: 10,000 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. THE SPOTS WITH DAYSM HOURS, 3D 24H 60M 60S 1D 1H 1M THEN, YOU FILL IN AND MINUTES. 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 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 OBJECTIVE NINE Sample Problem: 10⁰C = Problem 1: 112⁰F= Problem 2: -20⁰C= Problem 3: 23⁰C= OBJECTIVE NINE Answers Sample problem: 50⁰F Problem 1: 44.4⁰C Problem 2: -4⁰F Problem 3: 73.4⁰F OBJECTIVE TEN SAMPLE PROBLEM 12 mi=______km Answer: 15.54 Use gold sheet OBJECTIVE TEN PRACTICE PROBLEMS 1 mi2 _____ cm2 2 yd 2 _____ cm2 Answer: 1: 10,000 2: 8361
