Show all intermediate steps. If it is valid, provide a derivation of the conclusion justifying each step. If it is not valid, present a scenario in which all premises are true and yet, the conclusion is false. No need to use predicate logic for this question. (20 Pts.) If I study computer science, then I will make a lot of money. If I study archaeology, then I will travel a lot. If I make a lot of money or travel a lot, then I will not be disappointed. Therefore, if I am disappointed, then I did not study computer science and I did not study archaeology.

Ответ:
Unit rate = 1.25 inches per yard
Length of fence B on the blueprint = 5 inches
Step-by-step explanation:
We are told that Fence A is 1 1/5 yards long but is 1 1/2 inches long on the blueprint.
This means it's 1.2 yards long but 1.5 inches on the blueprint.
Thus, the unit rate for this blueprint will be; 1.5/1.2 = 1.25 inches per yard
fence B is 4 yards long.
Thus, the corresponding blueprint measurement = 4yards × 1.25 inches/yard = 5 inches.
