what is it that you need help on?
i need to find out if four diffrent fractions are equivalent to each other
i need help with something people !!
witch are 3/4 18/25 15/20 and 75/100 witch ones are equivlent
someone help me !
that was just some examples that are equal to 3/4
@myininaya help me .
no like it says out of thesse witch ones are equal to each other
im not talking about that . help me with something else .
Lauren, what is the question that you are trying to answer?
she wanted to know which one of those fractions were equal. 3/4=15/20=75/100
to each other
oh, so the 75/100 would be equal to 15/20?
lmaao , its ard girl(:
do you think you could help me out with one of my word problems?
born ready !
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 ?
im a freshman in high school. Algebra 1. Is this too hard for you?
haha . naah .
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
well , first think what exactly are they trying to ask you ? whats important in the problem and whats just gravy?
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
break it down.
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
i kinda showed you up there right?
Oh my gosh, THank you so much
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!
