I’d be curious to hear what you think is the easiest way to solve Test #9, Section 4 (Calculator), #18. A lot of the students I work with find this challenging because the question says p percent (rather than using p as a decimal).

Thanks!

Hi, Mike. How would you say the two math sections of the SAT are different (besides the obvious calculator use and the timing/number of questions)? I’m thinking in terms of content covered, types of questions, etc. Thanks!

What’s the *fastest* way to solve this problem?

Could you please explain Test #8, calculator-allowed section, number 28?

Thanks!

Hi, Mike! Just curious as to how you would best explain the following question:

Which of the following is the decimal equivalent to 2/7? (Note: A bar indicates a digit pattern that is repeated.)

A. 0. 285714 (all digits after decimal repeat: 0.285714285714…)

B. 0.28571428 (no repeating digits)

C. 0.28571428 (only digits 28 repeat: 0.285714282828…)

D. 0.2857142857 (no repeating digits)

E. 0.2857142857 (only digits 2857 repeat: 0.28571428572857…)

Thank you!

In the picture, Lines L1 and L2 are parallel, Lines L3 and L4 are parallel, L1 and L3 intersect on the circle, and L2 passes through the center of the circle. The angle theta equals pi/3, and radius R = 6. Find the area of the region A, which lies outside the circle and is bounded within the three line segments. Round your answer to the nearest hundredth. The answer is 29.72. Help!!

Would you please show how you would solve PSAT test section 4, #16? Thank!s

Can you explain a faster way to do this problem rather than figuring out the grams of protein per dollar for each one? Thank you!

The graph above shows the amount of protein

supplied by five different food products, A, B, C, D,

and E, as a percentage of their total weights. The

costs of 10 grams of products A, B, C, D, and E are

$2.00, $2.20, $2.50, $4.00, and $5.00, respectively.

Which of the five food products supplies the most

protein per dollar? (question 17, Section 4, practice PSAT)

A researcher conducted a survey to determine whether people in a certain large town prefer watching sports on TV to attending the sporting event. She asked 117 people at a local restaurant on a Saturday, and 7 people refused to respond. Which of the following factors makes it least likely that a reliable conclusion can be drawn about the sports-watching preferences of all people in the town?

A) sample size

B) population size

C) The number of people who refused

D) Where survey was given

The table above lists the results of a survey of a random sample of 250 high school seniors and freshmen. Each student selected one subject that was his or her favorite.If the sample is representative of a high school with 2,000 freshmen and seniors, then based on the table, what is the predicted number of freshmen at the high school who would select math as their favorite high school subject? A) 520 B) 240 C) 65 D) 30

B) x − 2 is a factor of p x( ).

C) x + 2 is a factor of p x( ).

D) The remainder when p x( ) is divided by x − 3 is −2.
