SAT Subject Tests were 20 multiple-choice standardized tests given by the College Board on individual subjects, typically taken to improve a student's credentials for college admissions in the United States. On January 19, 2021, the College Board discontinued Subject Tests. This was effective immediately in the United States, and the tests were to be phased out by the following summer for international students.
My take on it:
I used ##W = Rt## where ##W## is work done, ##R## is rate and t is the time taken
let ##W = 1## and ##t## be the time taken by lambert.
for Lambert:
##1 = R(t)##
##R = \frac{1}{t}## ... (1)
for Stassen:
##1 = \frac{r}{(3t/2)}##
##r = \frac{2}{(3t)}##...(2)
from (1) and (2),
## R'...
Hello,
Recently I viewed a blog post about SAT Math preparation. It stated that quadratics is the chapter which is most asked in SAT, and if I don't master the chapter, I can't answer most SAT problems. IMO, this statement above implied that quadratics (quadratic equation) is the core chapter...

sat math, "test-taking abilities," math ability
hey all,
are there good reasons for scoring low on the sat that do not stem from poor math ability?
what do these 'test-taking abilities' consist of and how do they operate?
i took a practice test today and i scored in the 580 range. now, i...
How do you guys think the SAT, manily the math section accurately judges ones ability? I have heard people say if you get below x, usually 600 to 700 you will never succeed in engineering or physics. I would think its more on how much you study and that the SAT is there more tovtrick you any...
I've actually already completed my first year of college, with quite modest results. Something which has been causing me quite a bit of psychological bother though is whether or not my SAT math score is a reflection of some kind of natural ability or intelligence, rather than a reflection of...
Hello everyone, I'm currently in high school and will be applying to universities this summer. I recently took my SATs and, although I did pretty well on the english sections (Writing=650 and Reading=600), I was extremely disappointed by my maths score (640). Now I'm not generally weak in maths...

Homework Statement
\sqrt{x^{2}-t^{2}}=2t-x
If x and t are positive numbers that satisfy the equation above, what is the value of \frac{x}{t}?
2. The attempt at a solution
x^{2}-t^{2}=4t^{2}-x^{2}
x^{2}+x^{2}=4t^{2}+t^{2}
2x^{2}=5t^{2}
I'm unsure of what to do next.

If point P(m,2m) is 5 units from the line 12x+5y=1, m could equal
a. 43/11
b.-3
c.-65/22

e.3
The answer is E.
Explanation given in book:
- distance = abs(12(m) + 5(2m) -1) / root(144+25) = 5.

What is the best precalculus textbook in your opinion that gives good examples and problems for you to practice on? Organization and the easy level of ability to comprehend would also be nice.
What's the best Precal textbook that would prepare me for the Math IIC? I'm looking for one that has lots of examples, can be understood easily, and includes a lot of practice problems for you to practice on. Thanks.
To make an orange dye, 3 parts of red dye are mixed with 2 parts of yellow dye. To make a green dye, 2 parts of blue dye are mixed with 1 part of yellow dye. If equal amounts of green and orange are mixed, what is the proportion of yellow dye in the new mixture?
This is not a homework...
When you divide any positive integer by 3, the remainder must be less than or equal to 2.
Does this hold true for all integers from 2-9?? I've tried it with 10 but it doesn't seem to work, nor 1 because anything divided by 1 is itself; 0 has the same issue.
Please give your insight about...

Okay, so I have... problems with math. As in, we repell. Big time. Right now I'm working towards my SATs, which I'm hoping to take this summer. I was wondering if anyone could give me the basics of what they'll test me on? I bought an SAT book, and I've been looking online, but I'm still fairly...
The College Board's website contains a "SAT question of the day" feature. As I'm going to be taking my SAT I's (as well as three SAT II tests, lucky me) in the near future, I check it on a regular basis in conjunction with the rest of my studies.
Today's question seems completely crazy...
