I 11

II 1

III 7

A. I only

B. II only

C. I and II only

D. II and III only

E. I, II, or III.

sat数学答案Correct Answer: E

sat数学真题解析:

Do not assume that AB and C are on a straight line. Make a diagram with A and B marked 5 miles apart. Draw a circle centered on B, with radius 6. C could be anywhere on this circle. The minimum distance will be 1. and maximum 11. but anywhere in between is possible.

2. √5 percent of 5√5 =

A. 0.05

B. 0.25

C. 0.5

D. 2.5

E. 25

Correct Answer: B

sat数学真题解析:

We can write the statement mathematically, using x to mean ‘of’ and /100 for ‘per cent’. So ( √5/100) x 5√5 = 5 x 5 /100 = 0.25

3. If pqr = 1 , rst = 0 , and spr = 0. which of the following must be zero?

A. P

B. Q

C. R

D. S

E. T

Correct Answer: D

解析:

If pqr = 1. none of these variable can be zero. Since spr = 0 , and since p and r are not zero, s must be zero. (Note that although rst = 0. and so either s or t must be zero, this is not sufficient to state which must be zero)
