I am a male and i am currently 14 and i am 5'7. However, my leg length is as big as a teacher in my school who is 6'4, in addition, i have a friend who is also 14 and he is 5'10 but we have the same leg length...

Does it mean i will grow as tall as the 6'4 teacher?
Will my legs keep on growing (my doc took me x rays and said my growth plates were open)?
When will my upper body grow?
In addition, my forearm length is quite small too, does it mean i finished growing?

A camel rests by a pile of 3000 bananas at the edge of a 1000-mile-wide desert. He plans to travel across the desert, transporting as many bananas as possible to the other side. He can carry up to 1000 bananas at any given time, but he must eat one banana at every mile. What is the maximum number of bananas the camel can transport across the desert? How does he do it?

hi all

The height (h) in metres above ground of a tip of minute hand can be modelled with this equation

h = 90 + 3.5 sin ( pi * t / 30 + pi / 2 )

calculate height above ground when the tip of minute hand is at 20 minutes past midnight.

i get the answer 88.25 m but i think it is wrong.

my working is:

90 + 3.5 sin ( pi * 20 / 30 + pi / 2) i took the height as 20, as the minute hand was at 20 past midnite. hence only 20 mins if we take the 24 hr clock 00.20 so used 20 as the height.

any help appreciated.

Thanks

heres the question: its a word problem:
when 400 mg of the painkiller ibuprofen is swallowed, the number of milligrams (n) in the bloodstream (t) hours later (for 0 n=0.5t^4 + 3.45t^3 - 96.65^2+347.7t

how many milligrams of ibuprofen remain int he blood stream 1 hours after 400 mg has been swallowed?

the answer is going to be 255mgs. but i have to show my work im doing everythign but its not coming out to that answer. if u dont wanna tell me how u got that answer can someone just tell me what to do so i can work it out or if u wanna work it out fo rme be my guest:) thanks!!

With the geo column stating that dinosaurs found in layers of rock dating so and so millions of years the question is:
Why is it sooo much easier to find dinosaurs that have been dead for at least 65 million years, than cro-magnum and any other form of man that havfe been dead for only 3 million years.
Cro-magnum, erectus, and habilius should be the frisdt things we encounter when we dig, instead it's easier to find dinos extinct for said millions of years in a column which indicates our ancient man cousins should be arrvinig first.
If anyone goes on about the difficulty of fossilisation after 3 million years, bear in mind they have found fossilised hats, hammers and cowboy boots, with fossilised cowboy feet inside them.
Further, if extinction and evo depend on changes to habitat, and some creatures have survived such as the caelocanth as its habitat is unchaged, then why did cro-mags, erectus, and habilius man dissapear?They lived in caves and jungles, which we still have today

I'm currently working on angles and bisectors and I was confused by the notes:

120degrees = x/2 + x/4 + x/8 + x/16
and multiply all that by sixteen to get:

120 * 16 = 15x
and then my teacher went from that to:

8 * 16 = x
can someone explain this to me? (from 120 * 16 = 15x to 8 * 16 = x)
thanks!
