  If , , and are numbers such that and , then is equal to which of the following?

  Answer Choices

  (A)

  (B)

  (C)

  (D)

  (E)

  The correct answer is A

  Explanation

  From is implied that (1)

  And from is implied that (2)

  If we multiply (1) and (2) together, we have that ( is canceled out).

  下面为大家提供一些和这些SAT官方每日一题相似的题目,供大家练习:

  In the line segment pictured below, AB + CD = AD, and AB = BC. If AD = 15,what is the distance between the midpoints of AD and BC?

  Note: Figure may not be drawn to scale.

  (A)0.5

  (B)1.5

  (C)3

  (D)4.5

  (D)7.5

  Correct Choice: B

  If you understand how to answer this question, you should be able to answer any question dealing with line segments on the Math IC. The question asks you to find the distance between two midpoints, so you first need to find where those midpoints are. By dinition, a midpoint is a point equidistant from both ends of a line segment. So the midpoint of AD is 15 2 = 7.5 units from either end. To find the midpoint of BC, you first need to find the length of BC. From the figure, you can see that BC = AD – AB – CD. Since it is given that AB + CD = 2⁄ 5AD,

  The midpoint of BC is 9⁄2 = 4.5 units from B and C. But in order to measure the distance between the midpoints of BC and AD, you must situate the midpoint of BC with regard to AD. You can do this by finding out the midpoint of BC’s distance from point A.

  Therore, the midpoint of BC is 4.5 + 4.5 = 9 units from a, whereas the midpoint of AD is 7.5 units from a. The distance between these two midpoints is 9 – 7.5 = 1.5.

  以上就是关于SAT官方每日一题中数学部分的详细内容,包括了题目和选项以及答案。大家可以在备考SAT的过程中关注SAT每日一题的内容,这样就可以更好有不间断的练习,也就能在日积月累的过程中得到提高。
