 1.三條任意直線，L1和L2的交點的個數(shù)與L2和L3的交點的個數(shù)沒關(guān)。

　2. The number of 1/4-inch lengths in 1

　a 4-inch length

　2，是問4英尺中有多少個1/4英尺，應(yīng)該是16個，所以是A

　3. The maximun number of solid cubes 4

　having edges of length 1/2 meter that

　can be placed inside a cubical box

　having inside edges of length 1 meter

　3邊長為1的立方體里最多能放下幾個邊長為1/2的立方體，當(dāng)然是8個咯

　4. Cube C has volume 8 cubic centimeters

　The area of one of the faces of cube C 3 square centimeters

　4立方體體積是8，那一個面的面積當(dāng)然是4咯

　5. Ms.Smith got an 8 percent cost-of-living raise of $20 per week

　Ms.Smith's new weekly salary $260

　5 x*0.08=20，那x+20=270>260

　7. For all real numbers a and b. if a·b=a(a+b), then a·(a·b)=

　A. a2+ab B a2+ab+a C a2+a+b D a3+a2b E a3+a2b+a2

　注：a2表示a平方，a3表示a立方

　7新定義的運算a·b=a(a+b), 那a·(a·b)=a·(aa+ab)=a(a+aa+ab)=aa+aaa+aab

　8.secretary typed 6 letters,each of which had either 1 or 2 pages.If the secretary typed 10 pages in all, how many of the letters had 2 pages?

　題目意思是這5個數(shù)哪些可以是2個>1的數(shù)的積,一個是奇數(shù),一個是整數(shù),只有6和14的因數(shù)中有奇數(shù),所以C.

　10 這句話大家看該怎樣列式子呢?這是一道圖表題.

　what was the approximate percent increase in personal income from 1965 to 1970?
