Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Product of an even number and any other number is






2. A<x and x<b






3. 5+3= 3+5 and 5 x 3= 3 x 5






4. V2/2- v2/2 - 1 (90-45-45)






5. Area= l x w perimeter = (2l)(2w)






6. x>0 and y<0 or x<0 and y >0






7. 180°






8. A collection of anything - numbers - letters - objects - etc. written within brackets { } two are equal if they contain the same elements.(order does not matter)






9. 1. square all choices given 2. select the closes choice that is too large and the one that is too small. 3. find the average of the two choices (not of the squares) 4. square the average - if it is greater than the original number - choose the lower






10. A line that is perpendicular to a radius and that passes through only one point of the circle.






11. If b²-4ac < 0 - there are






12. x older than y






13. If ?B > ?A - then






14. N is what % of m






15. Is - as - was - has - cost






16. All angles are right angles and diagonals are equal 1.each pair of opposite sides are equal 2. the diagonals bisect eachother 3. the opposite angles are equal 4. one diagonal divides it into two congruent triangles and two diagonals divides it into






17. C²= a²+b² and angle x and y are equal to 90°






18. Area= bh perimeter= 2a +2b






19. 1. solve the equation or inequality 2. use ONLY the solutions which satisfy the condition required - the set of all x such that x is greater than or equal to 10 R= {x: x=10}






20. The whole equals






21. In a triangle - the greatest angles lies






22. Between 180° and 360°






23. Any integer is divisible by 4 - if






24. 1/y-1/x x -y ? 0






25. ?






26. The case where the two equations are equivalent (just two different forms of the same mathematical relation). Any point that satisfies either of the equations - automatically satisfies both






27. x>z






28. Area= s² perimeter= 4s






29. Which - what






30. N= number of objects (order matters!!!) k= rate at a time nPk= n!/(n-k)! (remember to cancel common numbers)






31. Parallel and never intersect - they have no solution at all - they are parallel with the same slope






32. Write down every member in one or both of the sets - the union of two sets is a new set. the union of set A and B is written as A?B






33. Intersect at only one point - the point is the only solution to the pair of equations






34. If under the operation - any two members of the set constitute an element of the set ( * the product of the elements multiplied by themselves must also be an element of the set*)






35. (x1+ x2/2) - (y1+y2/2) Each coordinate of the midpoint is equal to the average of the corresponding cordinates of the endpoints






36. The distance from the center of the circle






37. 1-v3- 2 (90-30-60)






38. 2k + 1






39. Volume= 2/3?r² surface area= 2?r² (w/o bases) or 3?r² (with bases)






40. (amount of increase/original amount) x 100






41. z>y






42. Is drawn from the vertices perpendicular to the opposite sides. The lengths of these lines are useful in calculating the area of the trinagle since the area of the triangle is 1/2bh and the height and the _____are the same.






43. Any integer is divisible by 8 if






44. V3






45. x > y or y< x






46. The product of an even number of negative numbers is






47. 1. round the numbers being multiplied to one more place than it is being asked. 2. Multiply the rounded off numbers 3. round of product to desired number of places






48. x + y






49. Volume= e(edge)³ surface area= 6e²






50. The distance between two parallel lines or from a point to a line always means
