<p>I am just going through a practice test right now so I’ll post more as I review.</p>
<p>The British Factory Act of 1833 forbade employment of children under the age of nine, only the textile industries were affected.</p>
<p>The answer is “but the act applied only to the textile industries.”
I know the answer is grammatically correct, but if you read the original sentence it doesn’t really match with the idea. The act didn’t necessarily only apply to the textile industries, it only affected the textile industries. So how can this answer be correct??</p>

If you are affected by an “act” or a law, it obviously applies to you. For example, if a law says that people studying for the SAT are to be killed, then the law obviously only applies to the people studying for the SAT. Both statements–“only the textile industries were affected” and "the act applied only to the textile industries–are precisely the same. The original is wrong because it has a comma splice, which could be fixed with a semicolon, and because it is in the passive voice:</p>
<p>Passive voice (incorrect or undesirable): X was affected by Y.
Active voice (correct): Y affected X.</p>
<p>The passive voice is not grammatically incorrect, but the active voice is usually better. But notice that passive voice is not the only problem with the sentence; there is a comma splice, which is grammatically incorrect. In each question, the College Board tries to make 4 of the answer choices clearly incorrect and 1 of the answer choices clearly correct. Don’t be picky about an answer choice changing the meaning of the original sentence slightly or anything like that. Just pick the one that is most grammatical.</p>
<p>
First of all, “was equal” should be “was equal to” (X is equal to Y).
“Before” has many different meanings. In this case, “before” and “earlier” mean the same thing. Just look up “before” in the dictionary.</p>

You want the month to start as far from Sunday as possible. The 1st of the month either starts on a Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, or a Sunday. If the month starts on a Sunday, you automatically lose one Sunday and only have two more Sundays to go. If the month starts on a Monday, you will be furthest from the first Sunday and thus it would take longer for you to reach the third Sunday.</p>
<p>The month must start on a Monday. Three cycles of Monday-Sunday constitutes 3 Sundays. Hence, 3 full weeks and 21 days will have passed on the third Sunday.</p>

In the summer, 1/4 is washer fluid and 3/4 is water.
In the winter, 2/3 is washer fluid and 1/3 is water.</p>
<p>In the summer, (1/4)<em>(24 ounces) = 6 ounces are washer fluid; (3/4)</em>(24 ounce) = 18 water.
In the winter, the amount of washer fluid is twice the amount of water. There are only 6 ounces of washer fluid and 18 ounces of water. You want the amount of washer fluid to be 36 ounces, so you add 36-6= 30 ounces.</p>

OP = 8 inches is the length of the radius. This is the only thing we know. We can associate this given information with the diagonal OB of the square. Hence, we can see that the triangle OBC has two legs of equal length (squares have sides of equal length) and a hypotenuse with length 8.</p>
<p>8^2 = a^2 + a^2
64 = 2a^2 32 = a^2 = area of the square</p>
<p>
Set each individual factor equal to 0:</p>
<p>x+y = 0; x = -y or -x = y
x^2-y^2 = 0; x^2 = y^2 or -x^2 = -y^2</p>
<p>If any of the answer choices are x = -y, -x = y, or -x^2 = -y^2, then this is a faulty question.</p>
NOTE: I think the question is supposed to say “either one or two paintings.”</p>
<p>There are 12 artists and 17 paintings. Thus, there are 5 extra; each of these 5 people submitted an extra painting. Thus, everyone else submitted only one: 12-5 = 7 people.</p>
<p>7 people submitted 1 = 7 total
5 people submitted 2 = 10 total
Hence, there are 17 paintings total</p>

6. If x > 1 and a^3 = x^2, for what value of y does a^(2y+1) = x^6
Answer is 4<a href=“a%5E3”>/quote</a> = (x^2)
(a^3)^3 = (x^2)^3
a^9 = x^6 (multiply the exponents)
a^(2y+1) = x^6
2y+1 = 9
2y = 8
y = 4</p>

200 cars
(1) 50% are red; 100 are red
(2) 60% are four-door cars; 120 are four-door cars
(3) 70% have alloy rims; 140 have alloy rims
Given fact (1) only, we can conclude that a maximum of 100 cars can be green.
Given fact (2) in addition, we can conclude that a maximum of 80 cars can be green and two-door cars; 20 cars were lost because they were four-door cars.
Given fact (3) in addition, we can conclude that 80 cars can be green two-door cars with alloy rims. The other 60 with alloy rims are different.</p>
