How long doesi t take for each crane to unload this ship? I done most of the math but i am stuck with this last part .15+- radical 1185/2
No. of hours for the slower to unload alone—x: 1/x + 1/(x - 16) = 1/15 (x - 16 + x)/(x? - 16x) = 1/15 15(2x - 16) = x? - 16x 30x - 240 = x? - 16x x? - 46x = - 240 x? - 23x = - 240 + (- 23)? x? - 23x = - 240 + 529 (x - 23)? = 289 x - 23 = 17 x = 40 No. of hours for the faster to unload alone: = 40 - 16 = 24 Answer: slower crane, 40 hrs; faster crane, 24 hrs Check: = 15(1/40 + 1/24) = 15([3 + 5]/120) = 15(8/120) = 15(1/15) = 15/15 or 1
Q: my 7 year old son swears that a crane jumper is a type of animal...any one heard of this??
I googled crane jumper and came up with nothing. Not to say there isn't such a creature, that could be a regional name for it, it might be called something else.
Q: Romney woulda had that thing fixed by now.
It never ceases to amaze me. As Americans we scream and cry about the deficit and wonder why our president has not sent a work crew to fix a crane in NYC. These very same Americans suggest that our President is leaving the broken crane in New York to remind people of the atrocities done to the black Americans in our country. Really, nothing surprises me anymore.
Q: Grade 4 build a working crane Help!?
Simple crane? Get a spool, maybe one from sewing thread. Attach it to a small base so that it can rotate freely. Put a pencil through the middle tight enough so that when the pencil rotates the spool rotates. Glue a tab on the end of the pencil at a right angle to the pencil so you have a handle. Attach string to the spool and then maybe a ruler or stick to a base lined up with the spool like a crane. Put a couple of eye hooks on the stick and feed the string through so it hangs down at the end of the stick, like a crane cable. At the end of the string put a springy clothspin so that when you pull the string the clothspin opens and closes. Now you can lift and lower the clothspin by rotating the spool with the pencil. Pulling on the string opens the pin to pick up things.
Q: how do i win stuff in a crane machine?
Deposit many quarters in the machine or make friends with the man who puts the stuff in it. if you're extra nice, he may give you something- it's not his money, so he won't care.
Q: What is the most widespread animal Kung Fu style in the world?
Depends on the area but I'd think Mantis and Crane would be one of the top styles. Crane style is also used in other arts such as Karate and does have it's origin in the Chinese martial arts.
