witch are 3/4 18/25 15/20 and 75/100 witch ones are equivlent

- myininaya

3/4=6/8=9/12=12/16=15/20=18/24

- anonymous

someone help me !

- myininaya

that was just some examples that are equal to 3/4

- myininaya

3/4=15/20

- anonymous

@myininaya help me .

- myininaya

=75/100

- Lauren

no like it says out of thesse witch ones are equal to each other

- anonymous

im not talking about that . help me with something else .

- Lauren

thnxs myininaya

Lauren, what is the question that you are trying to answer?

- myininaya

she wanted to know which one of those fractions were equal. 3/4=15/20=75/100

- Lauren

to each other

- anonymous

duuuuuuuuuuuuuuuuuuuuuhhhhhhhhh

- anonymous

oh, so the 75/100 would be equal to 15/20?

- anonymous

YEEEEEEEEEEEEESSSSSSSSSSSS

- anonymous

K, sorry

- anonymous

lmaao , its ard girl(:

- Lauren

any more

- anonymous

do you think you could help me out with one of my word problems?

- anonymous

me ?

- anonymous

sure

- Lauren

yeah what

- anonymous

born ready !

- anonymous

ok, are you ready?
Lauren dove into a swimming pool from a 15-foot-high diving board with an initial upward velocity of 8 feet per second. Find the time t in seconds it took lauren to enter thh water. Use the model for vertical motion given by the equation:
h=-16t^2+vt+s, where h is height in feet, t is time in seconds, v is the initial upward velocity i feet per second, and s is the initial height in feet. (HInt: let h=0 represent the surface of the pool.)

oh my jesus . what grade are you in ?

- anonymous

im a freshman in high school. Algebra 1. Is this too hard for you?

- anonymous

haha . naah .

- anonymous

k, I learned how to do this last year because i was in algebra last year, but i failed. Anyway i have never remembered how to answer these type of questions

- anonymous

well , first think what exactly are they trying to ask you ? whats important in the problem and whats just gravy?

- anonymous

ok

- anonymous

Use the model for velocity motion given by the equation h=16t^2+vt+s, where
h is height in feet , t is seconds, v is the initial upward velocity in feet
per second, and s is the initial height in feet.
:
I think the equation should be h = -16t^2 + vt + s (-16t^2 is the downward force of gravity)
:
When the diver strikes the water, h = 0, therefore
-16t^2 + 8t + 15 = 0
Multiply by -1 and try to factor this
16t^2 - 8t - 15 = 0
(4t - 5)(4t + 3) = 0
Positive solution
4t = 5
t =
t = 1.25 seconds to hit the water

- anonymous

break it down.

- anonymous

so I need to know the height of the board and the upward velocity of 8 feet per second and i don't know what else

- anonymous

i kinda showed you up there right?

- anonymous

Oh my gosh, THank you so much

- anonymous

Yo kerianne23 I gave you a hint for that locker pellet if it helps. If you;re still there, and haven't solved it yet, check that out. If It doesn't help, get back to me!
