[unparseable or potentially dangerous latex formula]

where l = extra fencing needed (in feet)
d = diameter (in inches)
r = number of rows of barbed wire
x = distance between fence posts (in feet)
A = acres

I can't get any of these problems >:(

10F-36
Let:
v be the velocity in mph,
[unparseable or potentially dangerous latex formula] be the time zone delay (on the actual study guide, 8 hrs),
t be the duration of the trip (on the actual study guide, 11PM - 3:30AM = 19.5 hr),
and d be the distance.

[unparseable or potentially dangerous latex formula]

So on the study guide, [unparseable or potentially dangerous latex formula].

[FabensMath]

[nsguy1350]

The remaining ones.

11D-38

[FabensMath]

This one is a bad one but i prefer to memorize this than do it the "right" way.

11D-36

[FabensMath]

Hopefully this works:

11I-38:

[unparseable or potentially dangerous latex formula], Solve for [unparseable or potentially dangerous latex formula]

[unparseable or potentially dangerous latex formula]

[unparseable or potentially dangerous latex formula]=central angle
[unparseable or potentially dangerous latex formula]=angle you're looking for
[unparseable or potentially dangerous latex formula]=Marin's time to run a mile, the one running around the track ((in seconds or minutes, doesn't matter)
[unparseable or potentially dangerous latex formula]=Mary's time to run a mile, the one running in a line(in seconds or minutes, doesn't matter)

[unparseable or potentially dangerous latex formula]given time in hours
[unparseable or potentially dangerous latex formula]given distance

[unparseable or potentially dangerous latex formula]

Convert to ft/s^2 by multiplying by [unparseable or potentially dangerous latex formula](or convert given units into ft and s from the beginning)

09B-36.

[unparseable or potentially dangerous latex formula], get 2 solutions: [unparseable or potentially dangerous latex formula] and [unparseable or potentially dangerous latex formula]
[unparseable or potentially dangerous latex formula]

where [unparseable or potentially dangerous latex formula]slope of line given

[redhawk2015]

Can these questions (with #s changed) only show up on ?s 66-68? Or can they be placed somewhere else in the test?

[FabensMath]

[kd9485]

Can someone do 06B-37?

[nsguy1350]

OK, only two left, 06B-37, and 08D-37, I believe.
Let's get them done. I'll try to get the solutions.

[nsguy1350]

06B-37

OK, well I have some solutions, except they aren't mine (Fabens), so credit him.

Let a = arc length, c = chord length, where c is the arc length minus the distance moved, and d be the distance above ground.

[unparseable or potentially dangerous latex formula]
[unparseable or potentially dangerous latex formula]

Solve for r and [unparseable or potentially dangerous latex formula], then solve for

[unparseable or potentially dangerous latex formula].

The sin and the solving for two variables makes finding one formula difficult or not possible. You could simplify a bit more, only having to solve for one variable, if you use:

Solve for r: [unparseable or potentially dangerous latex formula]
Final answer: [unparseable or potentially dangerous latex formula].

Make sure you factor in the mm in the given problem, and you multiply by 100 at the end.

08E-37

Let [unparseable or potentially dangerous latex formula] be the jogger's distance (what you're solving for), [unparseable or potentially dangerous latex formula] be the speed of the hiker, [unparseable or potentially dangerous latex formula] be the trail length, [unparseable or potentially dangerous latex formula] be the minutes portion of the jogger's 1 mile time, and [unparseable or potentially dangerous latex formula] be the seconds portion. In the actual study guide problem, [unparseable or potentially dangerous latex formula].

[unparseable or potentially dangerous latex formula].

EDIT: Credit to Faben's once again. I only put it in the formula format.
EDIT: Somehow I did not see that Fabens had already put this up. Whoops :D

[nsguy1350]

Is that all the study guide solutions? Geometry and stated?
Having formulas instead of numbers really does help!
Thanks guys!
Now let's make sure we memorize these and get 25 points closer to 350! :D
