  SAT模拟考试题答案:

  1.Correct Answer: B

  Explanation:

  The marked angle, ABC must be more than 90 degrees because it is the

  external angle of triangle BDC, and must be equal to the sum of angles BDC (90)

  and DCB. Also ABC is not a straight line and must be less than 180. Therefore 90

  < 5x < 180 The only value of x which satisfies this relation is 20.

  2.Correct Answer: A

  Explanation:

  20 large cakes will require the equivalent of 10 helpers working for one

  hour. 700 small cakes will require the equivalent of 20 helpers working for one

  hour. This means if only one hour were available we would need 30 helpers. But

  since three hours are available we can use 10 helpers.

  3.Correct Answer: E

  Explanation:

  Indian stamps are common to both ratios. Mul

  ltiply both ratios by factors such that the Indian stamps are represented

  by the same number. US : Indian = 5 : 2, and Indian : British = 5 : 1. Multiply

  the first by 5, and the second by 2.

  Now US : Indian = 25 : 10, and Indian : British = 10 : 2 Hence the two

  ratios can be combined and US : British = 25 : 2

  4.Correct Answer: C

  Explanation:

  Draw the diagram. The diagonal of the rectangle is the diameter of the

  circle. The diagonal is the hypotenuse of a 3,4,5 triangle, and is therefore, 5.

  Circumference = π.diameter = 5π

  5.Correct Answer: D

  Explanation:

  If two sets of four consecutive integers have one integer in common, the

  total in the combined set is 7., and we can write the sets as n + (n + 1) + (n +

  2) + (n + 3 ) and (n + 3) + (n + 4) + (n + 5) + (n + 6) Note that each term in

  the second set is 3 more than the equivalent term in the first set. Since there

  are four terms the total of the differences will be 4 x 3 = 12
