a) Find the height of Edmonton's CN Tower, to the nearest metre.

b) Toronto's CN Tower is a tourist attraction with a height of 555 metres. How many times as tall as Edmonton's CN Tower is Toronto's CN Tower?

c) Edmonton's CN Tower has 27 storeys. If an office building were the height of Toronto's CN Tower, how many
storeys would you expect it to have? Explain.
solve step by step below, and don't put for me link because every time i don't find where is it , and please draw the shape .
and solve it by Trigonometry ​

Suppose we have a set of small wooden blocks showing the 26 letters of the english alphabet, one letter per block. (think of scrabble tiles.) our set includes 10 copies of each letter. we place them into a bag and draw out one block at a time. (a) if we line up the letters on a rack as we draw them, how different ways coukl we fill a rack of 5 letters? (b) now suppose we just toss our chosen blocks into a pile, and whenever we draw a letter we already have, we put it back in the bag and draw again. how many different piles of 5 blocks could result? possible? piles will contain at least one repeated letter? (c) if we draw out 5 blocks wit hout looking at them, how many different piles are (d) if we draw out 5 blocks without looking at them, how many of the possible 2. (4) consider the following formula. 12 give two different proofs, one using the factorial formulas and the other combina torial.
