Let A be an uncountable subset of R. Then, A contains a subset S, composed of at least 2 elements, with the so called "in between" property, that is: for every distinct elements x and y of S, there exists z in S such that x < z < y.

Could anybody please help me as to what the working out would be to answer this question? Thanks in advance:

A hedgehog wishes to cross a road without being run over. He observes the angle of elevation of a lamp post on the other side of the road to be 27 from the edge of the road and 15 from a point 10m back from the road. How wide is the road? If he can run 1m/s, how long will he take to cross?


Thanks

If a vector space has a basis {e1, e2, ..., en} and x is some vector in that space, then for the equation:

x = x1e1 + x2e2 + ... + xnen
where x1, x2, ..., xn are the components of x

to hold, do the base vectors e1, e2, ..., en have to form a standard basis (i.e. the basis must be {(1,0,...,0), (0,1,...,0), ..., (0,0,...,1)})?

and there is a machine where we have to weigh the sweets and the numbers come up on the screen like this:7.55, 6.35, 8.55.And they told me that if the number is like 6.55 it is the number 7 and if it is something like 4.35 it is the number 3 and then you have to add it to the number on the sheet.But I dont understand how to do this but would like to learn as I will be expected to do this one day and my other work colleagues could use this against ,me in any argument it is most definitely my achilles heel at that job. How do I teach myself this form of mathematics?I think it is fractions, my maths was never that good when I was growing up.
