Basic math review

Test Preparation SAT Preparation
1

<p>I was given this for practice by my math teacher. It isnt for grades or homework, but im really embarrassed this is supposed to be the easier side of SAT math and I can't get the answers !</p>

<p>Here I will type out the questions to you</p>

<h1>1 What is an incorrect variation of the formula for the volume of a rectangular solid</h1>

<p>1) V=lwh
2)W= V/ (lh)
3)h= V/ (lw)
4) none of these are incorrect</p>

<h1>2 G=2/3(x-4) so X=</h1>

<p>1) 2/3 ( X + 4)
2) 3G + 4
3) (3/2) X + 4
4) 3/2 ( X + 40</p>

<h1>3 The surface area, S, of a cylinder is given by the formula S=2(pi)rh + 2(pi)r(squared) - where h is the height and r is the radius of the base. Solve this formula for h and find, to the nearest tenth of an inch, the height of a cylinder with a radius of 2 inches and the surface area of 212 square inches.</h1>

<p>This one you have no choices you just gotta solve it.</p>

<p>If any of you could write back with some answers it would be greatly appreciate, and I know to you geniuses I probably seem pretty pathetic at math but I'm a minority at a crappy public school in inner-city New york city, and I have never been good at math - so give me a break. thx for the help, mike.</p>

<h1>1 4)</h1>

<h1>2 x = 4 + 2/(3*G)</h1>

<h1>3 h = (S - 2<em>pi</em>r^2) / (2<em>pi</em>r) = 14.9</h1>

<p>My advice is: try to improve your math skills. With that knowledge ... I mean what could be more essential than solving a simple equation?</p>

4

<p>i dont know how to improve them, i mean i take math classes but theyres like a lot of kids in the class and if i ask questions the teacher says im stupid</p>

5

<p>get a review book and self study im from a public school in NY too, I manage to get by :) good luck</p>

<p>Ask questions in class, if you teacher actually says you are stupid or belittles you in any way report them. No teacher should do that to a student.</p>

<p>The SAT/ACT review books also provide a good base knowledge for everything that you will find on the SAT/ACT respectivly.</p>
