Study Notes
Geometry
- The sum of the interior angles of a triangle is 180 degrees.
Real-World Applications
- If a bakery sells 250 loaves of bread per day, it will sell 250 x 5 = 1250 loaves in 5 days.
Algebra
- To solve the equation 2x + 5 = 11, subtract 5 from both sides to get 2x = 6, then divide both sides by 2 to get x = 3.
Discounts
- If a book costs $15, and a 10% discount is applied, the discount is $15 x 0.10 = $1.50, so the book will cost $15 - $1.50 = $13.50 after the discount.
Geometry
- The perimeter of a rectangle with a length of 6 cm and a width of 4 cm is 2(l + w) = 2(6 + 4) = 2 x 10 = 20 cm.
