  1. 15 Thing’s I Learned This Year Tamenia Smith

  2. Equations Have An Equal Sign • Equations –Is a statement that shows two numbers or expressions that are equal . An equations has an equal sign . • Example’s • 2=2 • 17=2+15 • X=7 • T+3=8

  3. Scale Factor • Scale Factor – number you multiply by to get a dilation • Dilation- when a figure is increase or decrease by a scale factor

  4. Pythagorean Theorem • Use This If You Are Looking Foe C. • A2 + b2=c2 Leg-b

  5. Box And Whisker Plot • 1. Order least to greatest • 2.find the median middle, If there are two pots in the middle find the mean of the data • 3.find the upper quartile • 4.find the lower quartile • 5.find the lower extreme (outliner) • 6.find the upper extreme (outliner)

  6. Adding Integers' • Example )(-2)+(-5)=7 • 1.) add the numbers together. • 2.)give the answer the same sign.

  7. Scientific Notation • Scientific Notation is a way of expressing really big numbers or really small numbers • 25,ooo,ooo,ooo-Standard form • 0.00000000025-Stanard form • 2.5 (10 13times)Positive Decimal • 2.5 -10 (negative decimal

  8. Subtracting Integer’s • Same –Change –Change • 1.)1# Stays The Same • 2.)Change the sign to addition. • Change the # After it to its opposite. • Use addition Rules. • Ex. -3n-(-6) • -3+6=3

  9. Percent Proportions • A percent is a ratio that compares a number to 100. • Part % • Whole=100 • Ex. What Is 30% Of 60 • x 30 • 60 100 • X=18

  10. Dimensional Change • Oringal Perimeter x S.F=new perimeter ….. • Ex. 2in. X scale factor of 2 • 3in. • 4in. • P.of org.=10in. 6in.

  11. Surface Area • Lateral –without Bases • Total- All Surface Area. • Surface Area- is finding the area of all sides & adding them up Cylinder A = R2 18.75 18.75 112.00 149.50cm B= 112cm 11.75

  12. Exponent • a symbol or number placed above and after another symbol or number to denote the power to which the latter is to be raised:

  13. Order Of Operations’ • 4 + 10/2 • 14/2 • 14/2 • =7 • PEMDAS • You Do The Addition First . • Then The Division.

  14. Greatest Common Factors And Least Common Factors • Gfc:24 and 36 • 24-1,2,3,4,6,8,24 • 36-1,2,3,4,6,8,12,36

  15. Subtracting Fractions • 7 3 = 4 1 • 8 8 8 2 • 1 Take Away 3 Pieces • Then You Get Your Answer And Simplify That And You Get You Answer.
