(A) 4
(B) 7
(C) 11
(D) 17
(E) 25
Explanation
1.The correct answer is D
At first, there arestudents in the class, andof them are seniors. It follows that initiallystudents are not seniors. Ifjuniors are added to the class, there will be, or, students in the class who are not seniors.
2.The correct answer is B
Squaring both sides of the equation square root (x minus a) = square root (x + b) gives the equation x minus a = x + b. Subtracting x from both sides now gives negative a = b, or a + b = 0
3.The correct answer is A
If the functionis dined by, and, then. Therore,.
4.The correct answer is C
Since the radius of the circle is 4, the diameter of the circle is 8. In a circle, the diameter is longer than any segment that can be placed entirely inside the circle. Therore, segments of length 8.10 or length 14.00 could not be placed entirely within the circle, and the correct answer is 7.99.
5.The correct answer is C
Choice (C) is correct. Sinceis equilateral, each of its angles has measure. It follows thathas measure. Sinceandare radii of the same circle, they are of equal length, and sois isosceles. Henceandeach have measure. Thushas measure, and sois aright triangle. Since, the side opposite theangle in, is of length, it follows that, the side opposite theangle, is of length.
6.The correct answer is A
If the function f is dined by function f of x= (2 times x) + 3, and function f of a = 11, then function f of a = (2 times a) + 3 = 11. Therore, a = (11 minus 3) over 2 = 4.
以上就是关于SAT数学练习题目及答案分析的全部内容，答案的分析非常详细。大家可以在备考自己的SAT数学考试的时候，进行适当的练习和应用。
