	How do i reverse this formula?		2013-04-20
		MK pose la question : I have 22,000,000 worth of gold and wants to want to resell the gold back with a profit. Each transaction of gold will have a transaction fee of 15%, so if i resell the gold back at 22,000,000, I will only get back 18,700,000 after 15% transaction cut. The current formula is X-15%X = Y where X = 22,000,000 and Y = 18,700,000 Will u be able to come up with a new formula if we don't know the value of X but we know the value of Y Something like this X-15%X = 22,000,000. How do i reverse this formula to find the value of X Thanks Penny Nom lui répond.

	deux wagons		2013-04-05
		Cyril pose la question : Bonjour, je suis confronté à un problème dont je n'arrive pas à trouver la solution. Le voici: "Deux wagons de masses 30 tonnes et 60 tonnes entrent en collision sur une voie ferrée droite horizontale, ne déraillent pas et restent collés ensemble après le choc. Juste après la collision, ils roulent ensemble à 10 km/h vers le nord. Sachant que le wagon léger roulait à 20km/h vers le nord avant la collision, la vitesse du wagon lourd avant la collision = ?" Je pense qu'il faut employer la formule de la quantité de mouvement "p=mv" mais je ne sais pas comment m'y prendre... Merci d'avance pour votre aide! Cyril Biselx Claude Tardif lui répond.

	A gravel pile in the shape of a triangular pyramid		2013-04-04
		Casey pose la question : Hello Right now I am stuck and I feel embarrassed because I feel like the answer is so easy I should know it. I am working on a project and need to find a volume of gravel it will take to occupy this triangular prism like area. I am not sure what formulas I should use whether it be that for the volume of a pyramid or something more complex? Basically it forms a right triangle at one side then from there all points slope to one singular point about 10412mm away. I am attaching a picture drawn up in paint with the actual dimensions to clear up any confusion. Thank you for any help. Casey Penny Nom lui répond.
