2000 pounds = 1 ton 2000x20 pounds = 20 tons 40,000 pounds = 20 tons
20t
30 * 20t * 10 = 6000t
y(t) = 3.5 - 3.5*e1-20t Then dy/dt = -3.5*e1-20t*(-20) = 70*e1-20t
20 gallons is approximately 75.702 litres.
No because 16s+20t when factored is 4(4s+5t)
Yes The 20T motor is slower than the 15T motor with The 19T pinion
h=20t-5t2+1
No, a 40t is bigger. 40t vs 20t refers to the number of teeth(that engages with the chain) that each wheel has at its circumference. The tooth size is fixed for all bikes that use the same chain spacing, so a 40t chainwheel will have double the circumference of a 20t wheel.
20t
We have to trust the equation you give us, telling us that the acceleration of gravity is 9.8,the tossing speed is 20 straight up, and the stone leaves your hand from 10 aboveground.If all of that is true, then H = -4.9 t2 + 20t + 10, and when the stone hits the ground,-4.9 t2 + 20t + 10 = 0Multiply both sides of the equation by -1 :4.9 t2 - 20t - 10 = 0We're not going to be able to factor that ugly thing,so we have to use the quadratic equation:t = [ 20 +/- sqrt(400 + 196) ] / 9.8 = ( 20 +/- 24.413) / 9.8I get 4.532 seconds (rounded)
If you mean 20t^2 -12t then it is 4t(5t -3) when factored
