  1. Marco rides his bike to and from work every day. If the round trip is 3.23 miles, how far will Marco ride in 7 days? 21 miles 22.6 miles 22.61 miles 226.1 miles Two lines are parallel if: They form 90 degree angles. They intersect at only one point. They are in the same plane and never meet. They are the same length. Do Now

  4. Exponents • Some extra notes: • Base0 = 1 • Ex. 30 = 1 • Base1 = Base • Ex. 121 = 12

  5. Powers of Ten Key Points: • Recall: • Move the decimal as many times as there are zeros • Multiply = move to the right • Divide = move to the left • Let’s take it a step further

  6. Powers of Ten Key Points: • When looking at exponents with a base of ten (ex. 10exp.), then the exponent is telling you how many zeros after the 1 • Ex. 104 = 10,000 • Ex. 109 = 1,000,000,000

  7. Powers of Ten Key Points: • So when solving powers of ten problems, the exponent tells you how many zeros there are • Ex. 5.8 X 103 = 5.8 X 1,000 = 5,800 • Ex. .29 X 106 =

  8. Powers of Ten Key Points: • So when solving powers of ten problems, the exponent tells you how many zeros there are • Ex. 5.8 X 103 = 5.8 X 1,000 = 5,800 • Ex. .29 X 106 = .29 X 1,000,000 =

  9. Powers of Ten Key Points: • So when solving powers of ten problems, the exponent tells you how many zeros there are • Ex. 5.8 X 103 = 5.8 X 1,000 = 5,800 • Ex. .29 X 106 = .29 X 1,000,000 = 290,000

  10. Powers of Ten • Powers of Ten with Decimals: • Ex. 4.6 X .001 = • 4.6 X 10-3 = • 4.6 ÷ 103 = 4.6 ÷ 1000 = .0046
