Answers:

2- D
\(4 \div \frac{1}{6} = 24 \)

3- B
Simplify and combine like terms.
\((6x^3-8x^2+2x^4 )-(4x^2-2x^4+2x^3 ) {\Rightarrow} (6x^3-8x^2+2x^4 )-4x^2+2x^4-2x^3 {\Rightarrow}
4x^4+4x^3-12x^2\)

4- C
the population is increased by \(15\%\) and \(20\%\).
\(15\%\) increase changes the population to \(115\%\) of the original population.
For the second increase, multiply the result by \(120\%\).
\((1.15) \times (1.20) = 1.38 = 138\%\)
38 percent of the population is increased after two years.

5- C
Surface Area of a cylinder \(= 2\pi (r + h)\),
The radius of the cylinder is \(3(6 \div 2)\) inches and its height is 8 inches. Therefore,
Surface Area of a cylinder \(= 2\pi (3) (3 + 8) = 66\pi\)

6- 170
Use the information provided in the question to draw the shape.

Use Pythagorean Theorem: \(a^2 + b^2 = c^2 \)
\(80^2 + 150^2 = c^2 {\Rightarrow} 6400 + 22500 = c^2 {\Rightarrow} 28900 = c^2 {\Rightarrow} c = 170\).

7- D
To find the discount, multiply the number by \((100\% –\) rate of discount).
Therefore, for the first discount we get: \((200) (100\% – 15\%) = (200) (0.85) = 170\)
For the next \(15\%\) discount: (200) (0.85) (0.85)

8- A
Use PEMDAS (order of operation):
\(5 + 8 \times (-2) – [4 + 22 \times 5] \div 6 = 5 + 8 \times (-2) – [4 + 110] \div 6 = 5 + 8 \times (-2) – [114] \div 6 = 5 + (-16) – 19\)
\(5 + (-16) – 19 = -11 – 19 = -30\)

9- A
\(x+2y=4\). Plugin the values of \(x\) and \(y\) from the choices provided. Then:
A. \((-2,3) x+2y=4(\rightarrow )-2+2(3)=4(\rightarrow )-2+6=4\) This is true!
B. \((1,2) x+2y=4(\rightarrow )1+2(2)=4(\rightarrow )1+4=4\) (This is NOT true!)
C. \((-1,3) x+2y=4(\rightarrow )-1+2(3)=4(\rightarrow )-1+6=4\) (This is NOT true!)
D.\( (-3,4) x+2y=4(\rightarrow )-3+2(4)=4(\rightarrow )-3+8=4 \)(This is NOT true!)

10- D
Let \(x\) be the integer. Then:
\(2x – 5 = 83\)
Add 5 both sides: \(2x = 88\)
Divide both sides by\( 2: x = 44\)

11- C
\(11 \times 36 + 6 \times 12 + 4 = 472\)

12- C
To find the number of possible outfit combinations, multiply number of options for each factor:
3 \(\times \) 5 \(\times \) 4 \(=\) 60

13- B
Let \(x\) be the smallest number. Then, these are the numbers:
\( x, x+1, x+2, x+3, x+4 \)
\( average = \frac{sum of terms}{number of terms} \Rightarrow 38 = \frac{x+(x+1)+(x+2)+(x+3)+(x+4)}{5} \Rightarrow 38= \frac{5x+10}{5} \Rightarrow 190 = 5x+10 \Rightarrow 180 = 5x \Rightarrow x=36 \)

14- D
Smallest 4–digit number is 1000, and biggest 4–digit number is 9999. The difference is: 8999

15- C
The area of the floor is: \(6 cm \times 24 cm = 144 cm^2 \)
The number of tiles needed\( = 144 \div 8 = 18\)

16- D
The relationship among all sides of special right triangle
\(30^ \circ -60^ \circ – 90^ \circ \) is provided in this triangle:

In this triangle, the opposite side of \(30^ \circ \) angle is half of the hypotenuse.
Draw the shape for this question:
The latter is the hypotenuse. Therefore, the latter is 60 ft.

17- B
\(average = \frac{sum of terms}{number of terms}\)
The sum of the weight of all girls is: \(18 \times 60 = 1080\) kg
The sum of the weight of all boys is: \(32 \times 62 = 1984\) kg
The sum of the weight of all students is: \(1080 + 1984 = 3064\) kg
\( average = \frac{3064}{50}=61.28\)

18- B
The sum of supplement angles is 180. Let \(x\) be that angle. Therefore,
\(x + 5x = 180\)
\(6x = 180\), divide both sides by \(6: x = 30\)

19- A
In the stadium, the ratio of home fans to visiting fans in a crowd is 5:7. Therefore, total number of fans must be divisible by \(12: 5 + 7 = 12\).
Let’s review the choices:
A. 12,324: \(12,324 \div 12 = 1027\)
B. 42,326: \(42,326 \div 12 = 3,527.166\)
C. 44,566: \(44,566 \div 12 = 3,713.833\)
D. 66,812: \(66,812 \div 12 = 5,567.666\)
Only choice A when divided by 12 results a whole number.

20- A
The percent of girls playing tennis is:
\(40 \% \times 25\% = 0.40 \times 0.25 = 0.10 = 10\%\)

Frequently Asked Questions

How many math questions are on the CBEST?

50 multiple-choice questions. The reading and writing sections add another 50 questions and 2 essays respectively. You have 4 hours total to complete all three sections in whichever order you prefer.

Is a calculator allowed on the CBEST?

No. No calculators are permitted on any portion of the CBEST. Practice mental math, especially with fractions, decimals, and percentages, well before test day.

Is there a formula sheet on the CBEST?

No. The CBEST does not provide a formula reference. Memorize area, perimeter, volume, the Pythagorean theorem, simple algebra, and basic stats formulas (mean, median, mode, range) before test day.

What’s a passing CBEST Math score?

41 scaled score per section is the standard pass. You can pass overall with a section score as low as 37 if your total across all three sections is at least 123 and no section is below 37. Most candidates aim for 41+ in each section to play it safe.

What math topics are on the CBEST?

Three content areas: Estimation, Measurement, and Statistical Principles (about 30%); Computation and Problem Solving (about 35%); and Numerical and Graphic Relationships (about 35%). Topics include arithmetic with fractions and decimals, percent and ratio, basic algebra, simple geometry, mean/median/mode, and reading charts.

How long does the math section take?

There’s no specific math-only time limit — you have 4 hours for the entire test and can split your time across reading, writing, and math however you choose. Most test-takers spend 60 to 90 minutes on math.

Can I retake the CBEST math section alone?

Yes. Once you pass a section, you don’t need to retake it. If you only need to pass math, you can sit for just that section. There’s no waiting period between attempts on computer-based CBEST.

How hard is the CBEST math test?

Content-wise, CBEST math is around grade 8 level — basic arithmetic, simple algebra, easy geometry, and reading graphs. The challenge for many candidates is doing it without a calculator and applying topics most adults haven’t touched in 10+ years.

How long should I study for the CBEST math?

Most candidates need 3 to 6 weeks of study at 30-45 minutes per day if math is rusty. If you’re already comfortable with arithmetic and basic algebra, 1-2 weeks of practice tests and targeted review is usually enough.

Is the CBEST harder than the GRE or SAT?

Much easier in content. The CBEST stays at grade 8 level; the GRE and SAT push into Algebra II and beyond. The CBEST’s twist is the no-calculator rule and the long 4-hour sitting that requires stamina across reading, writing, and math.
