AWA:

AI: 5.“All groups and organizations should function as teams in which everyone makes decisions and shares responsibilities and duties. Giving one person central authority and responsibility for a project or task is not an effective way to get work done.”

AA. 108. The following appeared as part of a business plan created by the management of the LACE>LACENAME>TakeLACENAME> LACENAME>HeartLACENAME> LACENAME>FitnessLACENAME> LACETYPE>CenterLACETYPE>LACE>.

“After opening the new swimming pool early last summer, Take Heart saw a 12 percent increase in the use of the center by members. Therefore, in order to increase the number of our members and thus our revenues, which depend on membership fees, we should continue to add new recreational facilities in subsequent years: for example, a multipurpose game room, a tennis court, and a miniature golf course. Being the only center in the area offering this range of activities would give us a competitive advantage in the health and recreation market.

Math:

  1. A machine distributes 10890 balls into 6 boxes, P, Q, R, S, T, V. Boxes, named accordingly (P, Q, R, S, T, V ) are on a conveyor belt. Into which box does the last ball fall?

Mine: 10890/ 6x6; reminder: 18= 6x3 => the third box

  1. An integer X, is less than 10. What is X?

1) 1< = X < = 3

2) the number of the thousandth digit of 10X^2= the number of the hundredth digit of X^2

3. (quoted from previous JJ.)A guy picks up fruit from a stand. If he chooses the same number of each fruit two times, we think these two times are the same. Otherwise， they are different. Can you tell if there are more than 7 fruits?

a) There are more than 18 choices to choose one fruit from each kind of fruit, but none has the same number.

b) There are more than 24 choices to choose one fruit from one kind and two fruits from another kind.

(Sorry guys, I can’t remember all the details about this one. Please don’t dig it too hard, if you can’t figure it out according to my notes.)

  1. Each of people voted once in an election, X got 483 from male voters, Y got 433 from female voters. How many votes did X get?

1) X got votes from 50% of male voters

2) Y got votes from 60% of female voters

Mine: B (433= F 60%, => F , => X = 483 + F 40%)

  1. An equation= 0.0004* 0.0025 * 0.000016 * 0.00000125 * 10 ^Y. What is the least value of y in order to make the equation whole as an integer?

Mine: 0.0004* 0.0025 * 0.000016 * 0.00000125 * 10 ^Y= 2* 10 ^(-17)* 10^Y

Y= 17

  1. A semicircle. The radius of it is 6 feet. A perpendicular line intersects with the diameter of the semicircle. The intersection point is 2 feet left of the center point of the semicircle. What is the height of the perpendicular line?

Mine: h^2 + 4= 36, h= 4v2

  1. Line AB // line CD horizontally, Line AC and line BD intersect with Line AB and line CD. Is line AC // line BD?

1) angle CAB = angle BDC

2) angle CAB + angle ABD = 180

  1. A survey of 200 people. 160 of them have a cell phone and 90 of them have a pager. If any of them have a cell, a page or both, what is the percentage of people who either do not have a cell phone or not have a page?

Mine: (200- (160 + 90- 200)) /200 = 75%

  1. A person bought A and B. The total cost of the expense is 1.6 How many A did the person buy?

1) the cost of each A is 0.35, the cost of each B is 0.45

2) the number of A = the number of B

10. A shipment includes 8 different prices computers. If three of the computers are selected randomly, what is the probability of selections that always include two of the most expensive computers?

11.What’s the reminder of (7^48 + 7^22- 5)/ 7 ?

12. The question will give you a graph that has several different points showed on it. One of these points, P is at (s, t). What is the point that is at (-t, -s)?

(You can figure out that (s, t) is some point at (-x, +y), therefore you can go with the one has (-y, +x).)

13. What is the reminder when n is divided by 3?

1) The reminder when n + 6 is divided by 3 is 2

2) The reminder when n^2 is divided by 3 is 1

14. What is the least value of the following choices?

-3/4 < X < -1/2

X^2, X^2 + 3X, X^3 … (There few combinations consist of X^2, X^3, 3X, So please get the rough idea of the question.)

15. A set of w includes all negative integers. Is the number of all the numbers in w odd?

1) the sum of all these numbers is odd

2) the product of all these number is odd

16. Which two lines are perpendicular with each other?

X+ 1/5=0; X+5=0

…..

The answer I chose is X + 5=0 and Y=5

17. Two cylinder jars A and B. The diameter of A is D, and the height of A is h.

The diameter of B is T, and the height of B is 2h. Which one has the least cost in each per volume.

1) 3T= 2D

2) The costs of A and B are given

18. For any number, there is an equation r*= - 1/r. What is the value of r* -(r-1)*

Mine: 1/(r-1)r

19. In xy plane, a point P is (a, b). If 0< a < =b, and the distance between P and the origin is v18, what is the least number of a?

Sorry no verbal JJ available.
