Hi. I am Asian and my math is supposed to be good. My sat2 Math scored 790, and I have a 5 on BC. However my last two sat math scores were 750 and 740. The 750 one has one wrong. It seems like I could never get my math perfect. I just did a practice test and guess how I got my problems wrong: one of them I forgot it is asking for an odd number, the other one I misread which two lines it was asking for. I did math practice problems for months and I never got perfect. All of the questions are results of carelessness. I am about to take another sat this saturday, and I don’t know what to do.
The solution is simple: underline what the questions asks for. Not only that… you also need to underline any special conditions (odd, x>3 etc) I had the same problem and as simple as my suggestion sounds, it helps a lot.
were you able to score perfect at the end?
Well I did not actually re-take the SAT yet. But in practice tests, I did.
thats good enough for me at least…
I used to get 780 until recently because of that one stupid mistake. But when I did a test recently with underlining, it stopped happening
nice. thank you. i will definitely try that this saturday
dude i just try one section with your method and got perfect. though it was just one section i almost cried
How do you solve this problem?
What is the greatest possible area of a triangle with
one side of length 7 and another side of length 10 ?
(A) 17
(B) 34
© 35
(D) 70
(E) 140
And this
20. If j , k , and n are consecutive integers such that
0 is less than j kn and the units (ones) digit of the product
jn is 9, what is the units digit of k ?
(A) 0
(B) 1
© 2
(D) 3
(E) 4
And this too please
14. There are 25 trays on a table in the cafeteria. Each tray
contains a cup only, a plate only, or both a cup and a
plate. If 15 of the trays contain cups and 21 of the trays
contain plates, how many contain both a cup and a
plate?
If 2 sides are given and you are trying to find the largest triangle, those will be the two shortest sides. If the triangle is a right triangle, the given sides will be the base and the height. If the triangle is not a right triangle, the height (at least in my visualization of this problem) will be lower so the area will be lower. Therefore the triangle with the greatest area as described above will have two sides of 7 or 10, one being the base and the other the height. Since a = (b+h)/2, a =35.
We know we’re working with positive numbers and that j times n ends in a 9 so we know that j and n either both end in 3 or one of them ends in 9 and the other in 1. Since j,k and n are consecutive they can’t both end in three. Since they’re consecutive, if one of j,k,n ends in 9 and another ends in 1, the third must end in 0. Since j and n end in 1 and 9, k must end in 0.
Guys thx for all your help! I got an 800 on sat math in October.
