1.55 CHF =?1 The price of the watch in Geneva is 1.55 CHF =?1 while 193 CHF =??1, which can be designated as x. Setting up a proportion, we cross-multiply, resulting in 1.55x = 193. Dividing by 1.55, we find x = 124.52 in x units. However, Manchester merchants are pricing it at 143 x units, so the difference is 143 - 124.52 = 18.48 units more expensive in Manchester.
3 distinct arrangements - 1 x 9 (or 9 x 1) and 3 x 3
Thus, the total number of arrangements = 2 x 2 = 4 = an even count
Initially, we identify pairs of different factors of 9.
The pairs of factors for 9 are:
(1, 9) and (3, 3)
For each of these pairs, Mr. Deets can create 2 arrangements.
This means the total arrangements Mr. Deets can construct = 2 x 2 = 4, confirming that the overall number is even.
The duration is 3 hours. We can define a variable for our answer (x). Now we need to determine the boat's speed in still water (y). We can establish this equation: d/t = s: 45/(y + 2.5) = 2 1/4, leading us to find y = 17.5. Substituting in the current’s speed gives us y - 2.5. So, 17.5 - 2.5 is 15. By solving for x, we get 45/15 = 3, which gives us the final answer of 3 hours.
