#### A class X cargo ship can hold a maximum of 18000 standard containers…

May 8, 2022#### I found this on the No Calc section of the March 2018 SAT, can you solve it the “traditional way” and with shortcuts (if there are any)? (it’s a grid-in question)

April 27, 2022Hi Mr. Mcclenathan,

I found this on the No Calc section of the March 2018 SAT, can you solve it the “traditional way” and with shortcuts (if there are any)? (it’s a grid-in question)

Tamika is ordering desktop computers for her company. The desktop computers cost $375 each, and tax is an additional 6% of the total cost of the computers. If she can spend no more than $40,000 on the desktop computers, including tax, what is the maximum number of computers that Tamika can purchase?

Thank you!!

#### Could you repost answer explanation to CollegeBoard Test 3, Math 4.23? Specifically, is there a way to solve this if you don’t know the little trig ID about complementary angles?

#### Introducing the 5th edition of the Math Guide

March 20, 2022I’m very proud to announce that the 5th edition of the world-renowned PWN the SAT Math Guide is now available at Amazon. This book keeps all the best parts of the 4th edition (which also remains available, for now) and provides some sweet updates. Most notably, the 5th edition contains 200+ new questions, most of (more…)

#### 2x^2 – 3x – 7 = 0 If c and d are the two solutions of the quadratic equation above, what is the value of c + d?

February 14, 20222x^2 – 3x – 7 = 0

If c and d are the two solutions of the quadratic equation above, what is the value of c + d?

Is there a smarter/quicker way to solve this than the quadratic formula?

#### Test #9, Section 4 (Calculator), #18

January 17, 2022I’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!

#### Which of the following equations describes a circle with radius 10 that passes through the origin when graphed in the xy-plane?

December 13, 2021Which of the following equations describes a circle with radius 10 that passes through the origin when graphed in the xy-plane?

A) (x – 5)² + (y+5)² = 10

B) (x – 5)² + (y+5)² = 100

C) (x – 10)² + (y+10)² = 10

D) (x – 5√2)² + (y+5√2)² = 100

Clearly, A) is out because that one does not have a radius of 10. What is the most time-efficient way to solve this? Sketch and eyeball?
