2024 SAT Standardized Test Math Practice Paper 26

The 2024 SAT standardized test is a critical assessment for college admissions. The math section covers a wide range of topics. To help students prepare, we’ve created a practice paper. This paper includes various math problems to help students become familiar with the test format and excel in their exam.

 

1. Reactant A is placed in a beaker, to which Reactant B will be added. Reactants A and B will not react unless B gets to a certain concentration. Once the reaction starts, both concentrations decrease until B has been consumed. Which of the following graphs, showing concentration in moles as a function of time in seconds, represents the reaction?

Sat math 25 2

Correct Answer: B

Answer Explanation:

According to the question, Reactant A does not react unless B gets to a certain concentration. Therefore, the correct answer will have an initial flat line for A while the line for B is rising. Only graph (B) shows this initial relationship. Therefore, the correct answer is (B).

2. -2y ≤ 8
y – 3 ≤ x
\( -\frac{1}{3} \)​y + 1 ≥ x

Which of the following graphs shows the solution to the system of inequalities above?

Sat math 26 1

Correct Answer: A

Answer Explanation:

All of the answers have the same lines graphed, so this question is really about the shading. Plugging In is probably the easiest way to approach this problem. Start with (0, 0) because this is an easy value to check. This works in all three equations since 0 ≤ 8, -3 ≤ 0, and 1 ≥ 0. Therefore, this value needs to be shaded as a possible answer. Eliminate (B), (C), and (D) because they do not include this point. The correct answer is (A).

If rectangle ABCD has an area of 324 and the tangent of ∠BCA (not shown) is ​\( \frac{4}{9} \)​, then which of the following is closest to the length of BD (not shown)?

A. 9.8
B. 27
C. 29.5
D. It cannot be determined from the given information.

Correct Answer: C

Answer Explanation:

Sat math 26 3

4. The population, P, of Town Y since 1995 can be estimated by the equation P = 1.0635x + 3,250, where x is the number of years since 1995 and 0 ≤ x ≤ 20. In the context of this equation, what does the number 1.0635 most likely represent?

A. The estimated population of town Y in 1995
B. The estimated population of town Y in 2015
C. The factor by which the population of town Y increased yearly
D. The factor by which the population of town Y decreased yearly

Correct Answer: C

Answer Explanation:

Use Process of Elimination to answer this question. According to the question, P represents the population, so the outcome of the entire equation has something to do with the population. Therefore, eliminate both (A) and (B) because 1.0635 can’t represent the population if P does. In the equation given, the only operations are multiplication and addition, which means that over time the population would increase. Therefore, eliminate (D). The correct answer is (C).

5. If x² + 12x = 64 and x > 0, what is the value of x ?

A. 2
B. 4
C. 8
D. 16

Correct Answer: B

Answer Explanation:

To solve the quadratic equation, first set the equation equal to 0. The equation becomes x² + 12x – 64 = 0. Next, factor the equation to get (x + 16)(x – 4) = 0. Therefore, the two possible solutions for the quadratic equation are x + 16 = 0 and x – 4 = 0, so x = -16 or 4. Since the question states that x > 0, x = 4 is the only possible solution. Another way to approach this question is to plug in the answers. Start with (B), x = 4. Plug 4 into the equation to get 4² + 12(4) = 64. Solve the left side of the equation to get 16 + 48 = 64, or 64 = 64. Since this is a true statement, the correct answer is (B).
