5 times because 8x5=40 and 40x8=48 so it can't go into it evely.
40x1=40 40x2=80 40x3=120 40x4=160 40x5=200 40x6=240 40x7=280 40x8=320 40x9=360 40x10=400
If you're working 40 hours with 8$ per hour, your equation is:40x8= 320$ per week.
Dude im in third grade and i counted 8 40 times and got 307 So.40x8=320 XD tennagers search this up tell me if im wrong or right WICH I KNOW I AM
A very common application of a quadratic equation is using the Pythagorean Theorem. The application is posted at http://www.mathmotivation.com/science/quadratic-application.htmlAnother application of a quadratic equation used in higher math and engineering is where a second-order differential equation is solved for a spring-damper system. This sounds scary but actually has real-world application. This example also shows how the "imaginary" number "i" is used in a real-world application. This application is shown at http://www.mathmotivation.com/science/complex-numbers-application.htmlYou wanted the quadratic function (2 variables). Here goes. The free fall equation S = at2 + Vot + So. is used by anyone predicting the path of a projectile. During WWII I have read that the warships would actually have a mathematician on board to do the calculations when firing at enemy targets. This equation, and how it is derived is shown at http://www.mathmotivation.com/science/freefall.html I once used this equation to calculate the depth of a canyon - I threw a rock straight out, counted the seconds, and was able to use the simplified version S = 16t2 to calculate the depth. Actually, the "canyon" was the bottom side of a dam on a river - my calculated depth gave me the depth of the lake on the dammed up side.
