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= 67,200,000Problem 2: 3.56x10⁻⁴= 0.000356Problem 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 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

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
