EXPONENT REVIEW:

43

4 is the base number, also called a factor.

is the exponent and tells how many times the base repeats itself.

43 : the base and the exponent are called a "power."

"Product" shows times the base repeats: 43 = 4X4X4

Find "value" or "evaluate" means solve: 43= 4X4X4= 64

Create a circle graph for this data:

Help

1.  Step One in making a circle graph is to convert your data first into fraction.We need to get the denominator first by adding up all the data values. The sum of all the data values is the denominator.  The numerators are the category data values already provided to you.
2.  Next, turn the fraction into a decimal by dividing the numerator by the denominator with the result being a decimal.
3. We then turn the decimal into a percent by multiplying the decimal by 100.

Integer Test Prep:

Day One - Adding Integers.  Remember if integers are both positive or both negative you add them and the common sign carries to the answer. IF the integers are MIXED, you subtract them and the answer gets the sign of the larger number.    ASSIGNMENT- COPY DOWN THE PROBLEMS AT THIS LINK, SOLVE THE PROBLEMS, AND ENTER THE CORRECT ANSWER. YOU MUST HAVE FIFTY (50) PROBLEMS CORRECT (SHOW  MR. WELLMAN YOUR SCORE-       CLICK HERE TO BEGIN

Day 3- Multiplying and Dividing Integers. Remember, it is good to have a pair of matching socks! When Multiplying and Dividing Integers that have alike signs,matching, the product or quotient is POSITIVE. Having a pair of socks that do not match is a bad thing (negative!) When Multiplying and dividing integers that have unlike (mixed signs) the product or quotient is NEGATIVE.  ASSIGNMENTS-1)  COPY DOWN  MULTIPLICATION PROBLEMS AT THIS LINK, SOLVE THE PROBLEMS, AND ENTER THE CORRECT ANSWERS.

THE METRIC SYSTEM

The basic prefixes in the metric system, from largest to smallest, are

Kilo Hecto Deka Base Deci Centi Milli

(where Base represents the base unit, such as meter, liter, gram, etc.)

Taking the first letter of each of these prefixes and using b for base unit,
we get the following sequence of letters: KHDBDCM

Now we just need to pick words that begin with these letters so as to make a sentence that will be easy to remember, the sillier the better:

Kangaroos Hop Down British Driveways Carrying M&Ms

or

King Henry Drank Both Diet Cokes Monday

or

King Henry Died By Drinking Chocolate Milk

Dividing Fractions:

Simple Fraction (no mixed): To divide a simple fraction you must multiply the 1st fraction by the reciprocal of the 2nd fraction. To make the reciprocal you "flip" the second fraction. For example 5/15 divided by 2/3 would become 5/15 multiplied by 3/2.  We would next solve the problem like any other multtiplying fraction problem using all the steps we have  already studied.

REMEMBER!!! ONLY THE SECOND FRACTION IS "FLIPPED!"

Divisibility Rules

for 2, 3, 4, 5, 6, 7, 8, 9,10, and 12

A whole number is divisible by:

• 2 if the number is even or if last digit ends in an even number. Ex. 358: 8 divided by 2 = 4
• 3 if the sum of its digits is divisible by 3.        Ex. 456: 4+5+6 = 15, 15 divided by 3 = 5
• 4 if the last 2 digits of the number are evenly divisible by 4. Ex. 288: 88 divided by 4 = 22
• 5 if it ends with 5 or 0. Ex. 3540: ends in 0 and is then divisible by 5.
• 6 if it is even and divisible by 3, it must be both.       Ex. 78: 8 is an even number and 7 + 8 =15 and 15 is evenly divided by 3 to get 5, so 78 is then divisible by 6.
• 7 --The rules are to take the last digit times 2, subtract this product from the rest of the digits remaining. Ex. 357: (double the 7 to get 14, subtract 14 from 35 to get 21 which is divisible by 7).
• 8 if the last 3 digits are divisible by 8.                       Ex. 6,032: (32 divided by 8 is 4).
• 9 if the sum of its digits are divisible by 9.                   Ex. 2,826: 2+8+2+6= 18,  18 divided 9= 2.
• 10 if the number ends in 0 (in the ones place).
• 12 if the number is divisible by both 3 and 4.              Ex. 8,256: 8 + 2 + 5 + 6 = 21, 21 is divided by 3 for 7.  The last two digits, 56, is divided evenly by 4 for 14.
