　　D. 1800

　　E. 18000

　　3. What is the average (arithmetic mean) of all the multiples of ten from 10 to 190 inclusive?

　　B. 95

　　C. 100

　　D. 105

　　4. A cubical block of metal weighs 6 pounds. How much will another cube of the same metal weigh if its sides are twice as long?

　　A. 48

　　B. 32

　　C. 24

　　D. 18

　　E. 12

　　5. In a class of 78 students 41 are taking French, 22 are taking German and 9 students are taking both French and German. How many students are not enrolled in either course?

　　A. 6

　　B. 15

　　C. 24

　　D. 33

　　E. 54

　　1.Correct Answer: B

　　Explanation:

　　One way to deal with fractions is to convert them all to decimals. (Using your calculator, divide the numerator by the denominator).

　　In this case all you would need to do is to see which is greater than 0.5.

　　Otherwise to see which is greater than ?, double the numerator and see if the result is greater than the denominator. In B, the correct answer, doubling the numerator gives us 8, which is bigger than 7.

　　2.Correct Answer: E

　　Explanation:

　　If an object travels at 5 feet per second it covers 5x60 feet in one minute, and 5x60x60 feet in one hour. Answer = 18000 (E)

　　3.Correct Answer: C

　　Explanation:

　　You could add up all the multiples of 10 (10 + 20 + 30 ....+190), and divide by the number of terms (19). Or you could realize that the average of an evenly spaced series of numbers is equal to the value of the middle term (or the average of the two middle terms if there are an even number of terms). The middle term out of 19 is the tenth term in the series = 100.

　　4.Correct Answer: A

　　Explanation:

　　If you double the sides of a cube, the ratio of the surface areas of the old and new cubes will be 1: 4. The ratio of the volumes of the old and new cubes will be 1: 8.

　　Weight is proportional to volume. So, If the first weighs 6 pounds, the second weighs 6x8 pounds =48.

　　5.Correct Answer: C

　　Explanation:

　　You could solve this by drawing a Venn diagram. A simpler way is to realize that you can subtract the number of students taking both languages from the numbers taking French to find the number taking only French. Likewise find those taking only German. Then we have:Total = only French + only German + both + neither

　　78 = (41-9) + (22-9) + 9 + neither.

　　Not enrolled students = 24

　　以上就是这五道SAT数学练习题的全部内容，包括了代数方面的习题，答案的解析非常详细清晰。大家在备考SAT数学练习题的时候，可以对上面的题目进行适当的总结，以便更好的应对SAT数学考试。
