psat questions

<p>how do i do #18 in math ( form S).</p>

<p>given: j, k, and n are positive, what is j+k+n
.30608= 3/10^j+ 6/10^k+ 8/10^n</p>

<p>Also, I dont understand #34 in writing.
The first woman in the US <em>to be granted</em> a patent was Mary Kies, <em>her</em> new method for <em>weaving</em> straw proved <em>useful to</em> hatmakers. I said <em>no error</em> but is the mistake "her" because I should say, "the method she invented"? Thanks..</p>

<p>Clarification on the math problem:
is it 3/(10^j) or (3/10)^j ?</p>

<p>Her is an error because of the comma splice; the solution doesn’t seem right, since it maintains the comma splice.</p>

<p>its 3/(10^j) on math. for the writing question, it says the mistake is <em>her</em> but idk why</p>

<p>Then it’s easy.
0.30608 is 3/10+6/1000+8/100000
Thus, j is 1, k is 3, and n is 5, so the answer is 9.</p>

<p>gah! ofcourse! thanks man</p>

Independent Clause 1: The first woman in the US to be granted a patent was Mary Kies.
Independent Clause 2: Her new method for weaving straw proved useful to hatmakers.
There are two independent clauses (also called simple sentences) being separated by a comma. (Independent clauses can stand on their own as individual sentences.) This results in a comma splice, which is grammatically incorrect. To fix the comma splice, you either separate the two clauses into two sentences or use a semicolon:
Ind-clause 1. Ind-clause 2.
Ind-clause 1; ind-clause 2.

Since “her” is the error, and not the punctuation mark (the comma), the sentence can be fixed by changing “her” to “whose”:

Here are a bunch of examples to help illustrate the problem:
INCORRECT: John is wearing a jacket, it costs a lot.
CORRECT: John is wearing a jacket, which costs a lot.</p>

<p>INCORRECT: John’s sister is Mary, she is awesome.
CORRECT: John’s sister is Mary, who is awesome.</p>

<p>INCORRECT: John has a sister, her cool personality makes her awesome.
CORRECT: John has a sister, whose cool personality makes her awesome.</p>

<p>In this context . . . </p>

<p>Pronouns like “it,” “she,” and “her” introduce independent clauses which can stand on their own as individual sentences. You can’t connect two independent clauses with a comma; the result of doing so would be the error called the comma splice.</p>

<p>Pronouns like “which,” “who,” and “whose,” called relative pronouns, introduce dependent clauses that can’t stand on their own, but depend on another clause (an independent clause). These relative (dependent) clauses can be connected to an independent clause by a comma.</p>
