Work is force times distance. Note that the only work done here is in the direction opposed to gravity, or if you prefer the change in height times the weight...
W=3sin20(8*9.8)
W≈80.44 J
This really depends on the fraction; if there are variables in the equation, if they are full numbers,etc. I'd really recommend looking up khan academy on YouTube and that will really help you out!
Answer:
1:4
Step-by-step explanation:
There are 200 cubes total. Out of those 200 cubes 50 are blue:
