I stink at math.

I need to know the formula that would answer this question:
$560 is 87.5% of what?

When I look up percentages on line I find "what is % of __this number__. That's not the problem I have.

Thanks for the help!!!

16, 17, 18, 19, 23, 24, 26, 27, 28, 29, 31.

First off, you cannot repeat the same number each time ( meaning you can only use "1" once when finding 16) Also no exponents. Only the numbers 1 - 5

if the patient needed an IV, would it be better to place the IV in the right arm (on the unaffected side), or would it matter which arm it is placed in?

Would not unilateral neglect of the left arm or loss of function or sensation in that arm be a consideration in deciding which arm to place the IV?

When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 8.0 km/s and the secondary, or S, wave has a speed of about 4.5 km/s. A seismograph, located some distance away, records the arrival of the P wave and then, 110 s later, records the arrival of the S wave. Assuming that the waves travel in a straight line, how far (in terms of m) is the seismograph from the earthquake?

Show that a subset A of R^n is compact if, and only if, every continuous function from A to R is bounded.

If A is compact, then for every continuous function f from A to R, the set f(A) is compact and, therefore, bounded. So the conclusion is trivial. But the converse seems to be kinda more difficult to prove.

Thank you

I've often heard it said that Leonardo da Vinci invented the helicopter. Pah! I've seen the rough sketch he did and it looks like an oversized corkscrew. And the Mona Lisa is a bog standard bit of artwork. Why is everyone always sucking up to Leonardo? Anyone agree?
