How much iron can be recovered from 25.0 grams of FeO?

science
In order for conduction to occur particles must make what?

algebra
86 degrees Fahrenheit = 30 degrees Celsius so, (30,86)

Physics
I have one problem I just can't figure out, A machine in an ice factory is capable of exerting 3.30 * 10^2 N of force to pull large blocks of ice up a slope. The blocks each weight 1.21 * 10^4th N. Assuming there is no friction, what is the max angle that the slope can mak...

physics
A. 5.729 m/s^2 B. 51.5625 m/s^2 C. 183.333m D. 70,088m

physics
A. a = v/t 165km / 8s = 20.625 km/h/s B. t= 60s-8s =52s, V= 1650km/h-165km/h =1485km/h a=v/t 1485km/h / 8s= 185.625km/h/s C. d=1/2at^2 1/2 * 20.625 km/h/s * (8s)^2 = 183.333m D. 60s-8s=52s d=1/2at^2 1/2 * 186.625km/h/s * (52s)^2 = 70.088km

math
I would set up a proportion meters 1 x ---- --- --- scale 2.5 100 (% means out of a hundred) Since 25 x 40 = 100, then 1 x 40 = 40 The bridge is 40m long.

Math-Algebra
3|x+5|<= 6 |3x+15|<= 6 -15 -15 |3x| <= -9 /3 /3 x <= -3 Yes, you are correct.

algebra
You need to set up the proportion Base 6.5m 4m ---- ---- ---- Length 3.7m e Then you cross multiply: 6.5xe=6.5e 4x3.7= 14.1m So therefore, 6.5e = 14.1m Then divide both by 6.5 to get what e equals. 6.5e/6.5 = e 14.1/6.5 ≈ 2 so e ≈ 2.
