jimthompson5910 (jim_thompson5910):

do you have anything so far?

OpenStudy (gabbyalicorn):

umm no ive tried to read it again and again but it doesn make any sense for which catagory to put them in ;/

jimthompson5910 (jim_thompson5910):

"A right triangle with one leg of 6 inches and area 24 square inches" what must the height be?

OpenStudy (gabbyalicorn):

3 ? because 6 x 3 = 24

jimthompson5910 (jim_thompson5910):

6 times 3 isn't 24

OpenStudy (gabbyalicorn):

oh 18 :/ i dont know where my brain is today

OpenStudy (gabbyalicorn):

i meant 6 x 4

jimthompson5910 (jim_thompson5910):

6 times 4 = 24 works if you have a rectangle that is 6 by 4

jimthompson5910 (jim_thompson5910):

but with triangles, you cut that in half to get the area area of triangle = (base*height)/2

OpenStudy (gabbyalicorn):

so 6 x 4 = 24 / 2? = 12

jimthompson5910 (jim_thompson5910):

but we want the area to be 24, not 12

OpenStudy (gabbyalicorn):

-3- hmm

jimthompson5910 (jim_thompson5910):

|dw:1433454993132:dw|

jimthompson5910 (jim_thompson5910):

how can we fix it? what must 4 be changed into?

OpenStudy (gabbyalicorn):

2?

jimthompson5910 (jim_thompson5910):

|dw:1433455132539:dw|

jimthompson5910 (jim_thompson5910):

hmm seems like the area got smaller when we wanted it to get bigger

OpenStudy (gabbyalicorn):

so 6 x 6

jimthompson5910 (jim_thompson5910):

6 times 6 = 36 cut that in half: 36/2 = 18 remember we want an area of 24

OpenStudy (gabbyalicorn):

but i dont know how to get there

jimthompson5910 (jim_thompson5910):

solve for h (6*h)/2 = 24

OpenStudy (gabbyalicorn):

whats the hieght

jimthompson5910 (jim_thompson5910):

(6*h)/2 = 24 6*h = 24*2 6*h = 48 h = ???

OpenStudy (gabbyalicorn):

um so 6 x4=24 6x 8 - 48

jimthompson5910 (jim_thompson5910):

yeah the height must be 8

jimthompson5910 (jim_thompson5910):

it cannot be anything else, which means only 1 triangle is possible

OpenStudy (gabbyalicorn):

oki

OpenStudy (gabbyalicorn):

but there are more boxes

OpenStudy (gabbyalicorn):

Well, thanks for your help. :)

jimthompson5910 (jim_thompson5910):

ok let's go over the other boxes

jimthompson5910 (jim_thompson5910):

"A scalene triangle with whole number side lengths and perimeter 6 inches" what possible triangles can you think of here?

OpenStudy (gabbyalicorn):

no angles

jimthompson5910 (jim_thompson5910):

you sure? no triangles possible?

OpenStudy (gabbyalicorn):

ya cuz scalene is no sides 0

jimthompson5910 (jim_thompson5910):

scalene just means all 3 sides are different

jimthompson5910 (jim_thompson5910):

what 3 whole numbers add up to 6?

OpenStudy (gabbyalicorn):

18

jimthompson5910 (jim_thompson5910):

re-read my question

OpenStudy (gabbyalicorn):

i dont know 2?

jimthompson5910 (jim_thompson5910):

2 and what else

jimthompson5910 (jim_thompson5910):

2 + _____ + ______ = 6

OpenStudy (gabbyalicorn):

3 and 1

jimthompson5910 (jim_thompson5910):

yes

jimthompson5910 (jim_thompson5910):

it turns out this is the only way to add up 3 different whole numbers to get 6

OpenStudy (gabbyalicorn):

:/

jimthompson5910 (jim_thompson5910):

what's wrong?

jimthompson5910 (jim_thompson5910):

where are you stuck?

OpenStudy (gabbyalicorn):

i dont even know...i feel like i cant even do this problem A) its logged me out of the question and has a new question :/ and B) i just....so hard :'(

jimthompson5910 (jim_thompson5910):

well take a break from it. I'd be frustrated too at tech like that

OpenStudy (gabbyalicorn):

ya k

OpenStudy (gabbyalicorn):
