answer to #2 is 4

4 + 1/4 = 4.25 divide that by 2 to get the average, and you get 2.125 which is equal to 17/8

t=4, that is your answer.

damn! I didnt think of that!!!!!!! Thanx a lot! Coffee and donuts are on me next time!!!!!

How about this one!

Two boys agree to mow a 60 by 80 m lawn so that the first boy cuts one half by cutting a uniform strip around the lawn. How wide a strip should the first boy cut?

Dont i have to divide by 2 or something?????
HELPPPPPPPPPPPPPP!!!!!!!!!

hey bmwm5lover are u a math teacher or u doing a degree on math those was very good question but sorry ia m not good in math
i hope u can post some of these problems i really like it

bmwm5lover · 07-09-2003, 02:17 AM

I SUCK IN MATH SOOOOOOOOOOO BAD! im only good in language based courses! Math and sciences I REEK IN!!!!!!!
Thanx so much for the help Guys! Now lets do that last one!!!!!!!!

So how did u get that number? using logic?

ya sorta, i figured something out that made sense to me, but now I forget how i did it

i do that all the time its not even funny.

how about this one.... Should be a bit easier....

The altitude(height) of a triangle is 3cm. more than its base. What are the dimensions if the area of the triangle is 29cm.

???????????????

bmwm5lover · 07-09-2003, 02:26 AM

i forgot to inlcude what i have. see if im right

i have this:
Base=3cm
Height= 6cm

3X6=18
29-18=19
19=dimension.
Dont ask how i got all this........

Jon@Bimmersport · 07-09-2003, 02:33 AM

answer to all of our questions:

terry + women = ?

oh right i forgot, they cant be added..

Dave 325i · 07-09-2003, 05:31 AM

Triangle question:

Area of triangle = 0.5*b*h

Let base = x
Therefore height = x + 3

Using area formula

29 = 0.5 * (x) * (x + 3)

Solve for x using quadratic equation.
Take the positive value, that is your base. The height is base + 3.

I got 6.26 for the base and 9.26 for the height.

=================

Lawn question:

Area of lawn = 60 * 80
Area of lawn = 4800 sq. metres.

One boy wants half - so 2400 sq. metres.

It's easier to do the question if you draw a diagram.

Let x be the unknown width.

2*(80x) + 2[(60 - 2x)*x] = 2400
Solve using quadratic equation or by factoring. Pick the answer that makes the most sense.

I got 10 metres wide.

dave is good... i knew dats whut u had 2 do, but was too lazy to do any of it, screw math, who needs math to succeed in life, pfft, lol
