Also note that for the last question, you can just make up numbers for the initial heights, bases, and areas. Then you solve for the new ones. So if the height was originally 10 and the base was 5, the area would be 25. Then, to follow the new description of the dimensions and area. The height would be 15, base would be 5(x), and the area would be 25*1.2=30. Set it up as (15*5x)/2 = 30 and solve for x. you get x=0.8, so 80% of the original base so it's a 20% decrease.
Amother easy way to solve qstn num 6 is that draw a line that connects lines l and m. This results in formation of pentagon . The sum of angles of pentagon is 540 . Sum of all angles gives the answer.
THANKS for really helping vidoes, currenlty im taking a gap year and just learning my exam by my own and your tutorials are just really helpful. I would personally recoomend you to the hardest words math problem of SAT question like comparison and things needed a litle bit trick on it.
I think there's also another way to solve the third problem: extend the radius and we have a right triangle. By that, we could find the inscribed angle for the same arc with the central angle. The degree of central angle = 2* the degree of inscribed angle.
If we multiply an odd number by an even number, we are just taking an odd number groups of even numbers, hence the result will always be an even number. Try coming up with 2 numbers, one odd and one even, where the product does not result in an even number. You can’t do it, because the product of an odd number and even number will always be even.
The exponents can be any positive integer, even or odd. We use the logic described in the video to determine that if one exponent is even the other must be odd.
its bc the product is a negative number. to get a negative number you must multiply a positive number by a negative number. thus since you know both x and y must be less than 0, then u implement the different exponent properties. a negative number to the power of an even number gives you an positive number (for instance -2 * -2 = 4) and a negative number to the power of an odd number gives you a negative number. therefore one of the exponents has to be even and the other odd so that we get a positive number * negative number = negative number. then an even * odd = even
@@OverclockingCowboy wtf are you talking. there are all sides with side length 'r' so it is an equilateral triangle, so all angles should be 60 deg ? also, it is my bad, he had done it but i skipped the video to the part where he did it intricately.
@@quillerity07 I will explain further. Once you know that an angle is 60, then the sine value of that angle is always sqrt 3/2. It is a special angle that most people memorize for convenience. It does not have to be a part of an equilateral triangle. It could be a part of a 60 - 50 - 70 triangle. The guy uses equilateral triangle to show that the angle is 60 degree.
@@OverclockingCowboy i skipped the video to the part where he approached the ques differently (in an intricate way), that's it. Clearly, there is a misunderstanding here
@DrewWerbowski, these questions are too easy and only require basic elementary school math foundations. Geometry accounts for only 15% of the SAT, while algebra and advanced math (polynomials, functions, etc.) make up 70%. We need to focus more on challenging algebra (35%) and advanced math (35%) since they represent the majority of the test. Geometry and statistics/probability, which are 15% each, are less difficult. I'm taking SAT on October 5th with target score 800 on Math total 1550+
Thank you for the feedback. It’s difficult to find SAT resources with as hard questions as you and some others are requesting. All of the “hardest” level questions from SAT practice material is about the difficulty of these questions, and I’m hesitant to pull harder questions from non-SAT material. Exactly what concepts with algebra and advanced math do you and most people struggle with?
@@DrewWerbowski John Jung's SAT Math content (Admission Hackers) UA-cam channel is incredible! His explanations are clear, especially for the more challenging questions that tend to trip up students like myself. Tricky quadratic equations and harder questions involving lines and coordinate geometry are particularly tough, while exponents and radicals are usually easier but can occasionally be deceptive. For practice, I’ve been using various books and past real tests since College Board hasn’t changed much in terms of concepts or question styles for algebra and advanced math on the digital SAT. The content remains almost identical to that of the paper SAT. I recommend you to look into paper SAT Math (real tests)
@@DrewWerbowski moslty word problem with combinatory applied and probability advanced, i have a bunch of hard questions already, where can i send you all of these?
i would disagree. while geometry might not be the most tested math topic, it does account for a good chunk of those harder questions. if you are working towards a 800 then u rly want to make sure to be proficient with all these concepts (plus i would say geometry often requires more outside of the box thinking than ur traditional advanced math).

3 days to go for the SAT. Really appreciate your videos targeting the hard math questions ❤ hoping for that 800!
Thank you for watching and commenting! Best of luck on your test :)

You know the interior angles very well.
amazing video. waiting for more of these
Can you please consider making vids on probability and statistics ? I have a course on it next semester and your teaching would be very helpful.

Thank you so....much for such a great video
THANKS FOR THIS VIDEO YOUR VIDEOS ARE HELPING ALOT HOPING FOR 800 IN MATH BUT LACKING IN ENGLISH
for last ques , just assumed the area to be 100 , base =4 and h=50, and do the operations accordingly.
good job boyy❤🎉

Great video, but I am still confused on the 2nd question's explanation. Shouldn't ab be odd?(C)?
If we multiply an odd number by an even number, we are just taking an odd number groups of even numbers, hence the result will always be an even number. Try coming up with 2 numbers, one odd and one even, where the product does not result in an even number. You can’t do it, because the product of an odd number and even number will always be even.
@@DrewWerbowski oh ok gotchu, was a bit confused. Thanks for the explanation!
These questions are in the book I have
Please what is the name of the book
Hey for question 2 is the exponents even because the product of the equation is a even number? im so confused
The exponents can be any positive integer, even or odd. We use the logic described in the video to determine that if one exponent is even the other must be odd.

wait what ? for qn 3, it is an equilateral traingle so all of the angles has to be 60 deg, so sin 60 = sqrt(3)/2?
Sin 60 has a fixed value regardless of the shape of the triangle. The guy is right.

@@quillerity07
Each angle is 60 degree, and sin 60 is sqrt 3/2. So what were you wondering before?
