THANKS ALOT!!! THIS VIDEO REALLY BROUGHT IT ALL HOME AND BRIGHTEND MY UNDERSTANDING.:-)

[Kalekenov]

I'm so glad this is considered a hrad math problem, realized I can spend more time on my english

[CarolinaCollegePrep1]

@Kalekenov ~ Congrats on your math skills! That said, please take a look at this problem before assuming the Math Section will be a piece of cake. There are typically 4-6 of this type on every SAT, and they cause even good math students to stumble.

A pipe with a radius of y, can fill a swimming pool in x hours. Assuming the maximum flow of water through the pipe at all times, what part of the pool will be filled in z hours?

a. y + (xz)

b. yz/yx

c. zy/x

d. yz + yx

e. zx/2y

@CarolinaCollegePrep1 B) I used values y=10, x=10 and z=2, you just need to know that x (the total number of hours) is the 100% of the of the pool and z ( less hours than x) is the part that would be filled. the value of y doesn't matter, you only need to give a value to x and z, (y is eliminated because it is divided by itself: (yz/yx) I first solved that z is 20% of the whole pool, I just plug in the number to all the variables with the numbers I used to solve

@CarolinaCollegePrep1 and the correct one'll be the one with the same answer I go: 20.

[CarolinaCollegePrep1]

@TheTico305 ~~~ Very VERY Nicely done! The process of exchanging the variables for numbers is a crucial skill we train in our DVD series, and you have done exactly what we'd recommend. Keep in mind however that "occassionally" random plug-ins will often generate what appear to be multiple postive outcomes (in other words, it may appear that A and D both work ~~~ but only one of those will be right). In the example problem above, this did not occur, but it often does. Good luck on your SAT!

@CarolinaCollegePrep1 is it E, and I can u make some videos on ones with hard word problems?

[CarolinaCollegePrep1]

@rampotown Word problems (especially the hard ones) are exhaustively covered in the 5-Disk DVD packet. The best part is that with our system, even the most difficult word problems can be solved with 4th grade math. As to the "answer E" ~ assuming you are speaking to the problem about the pipe filling the swimming pool (see my reply to Kaleknov's comment), then "no" the answer is not "E." Still in our system, we show you how to work this problem also with 4th grade math skills. Best, Coach W.

@CarolinaCollegePrep1 The answer would just be z/x I think not yz/yx because the y's would cancel out.

Hey CarloinaCollegePrep1, I was an American student but left to Hong Kong when I was 14. After years of integration of the Hong Kong's "math system" and coming back to watch this video; I realize that a "level 5" question is easy enough for my 9 year old brother to do (not meant to be boastful). My question is, in your opinion do you think SAT math is difficult? And would you suggest me taking it? I do apologies in advance if this is too broad of a question. Any comments would be appreciated.

[CarolinaCollegePrep1]

@lildarkkill ~~ Okay ~ this IS difficult for most people. In fact, the problem receives the most difficult rating of problems in the math section according to College Board (the guys that design the SAT). If 100 college bound kids were given the question and 2 minutes to work it, only 20 or so would be able to get it correct. With my system, even a 5th grader could work the problem correctly ~ as we eliminate the algebra.

You will need to take the SAT or ACT to gain college admissions.

[CarolinaCollegePrep1]

@martinurd ~~~ College Board, the designers of the SAT, rate this type of problem as "Level 5" ~ the hardest category of problem on the exam. It is possible to miss a few problems on any SAT regardless of difficulty level, and still gain admission into the toughest schools in the country; so "yes," I was serious when I said students at MIT and/or Harvard could miss this problem, but still gain admission. Using our system ~ it becomes a 4th grade math problem ~ which is nice!

[martinurd]

were you serious when you said that MIT or Harvard students had difficulty with problems like this?

[sharindaloveo5]

It's easier if you multiply the first equation by 2, then line up both equations on top of each other & add them. The x cancels out & you can simplify the rest.

[CarolinaCollegePrep1]

@sharindaloveo5 ~ you've presented the "traditional math class approach" to solving the problem, but your assessment that it would be "easier" to do it that way is incorrect. Out of 100 random seniors, only 20 would get the problem correct. This is why it receives a level 5 difficulty rating from College Board . The beauty of our system is that it works for those who cannot remember all of the things they learned in algeabra, and who are 'not all that great' at math in general.
