A person at 200 meters from the base of a tree, observes that the angle between the ground and the top of the tree is 30 degrees. Estimate the height h of the tree:
Solution: tan(30º) = h / 200 So, h = 200 m * tan(30ª) = 114 meters.
Jhony Pizza's has reduced prices by 20% on everything. If a Margarita Pizza cost $5 before the price reduction, How much does it cost now?
Let's calculate the final porcentage that applies to the price. Final porcentage = 100% - reduction (20%) = 100% - 20% = 80% So, the final Pizza price will be: 5$ * 80% = 4$
