0.4 x 200 = 0.4 x 10 x 20 = 4 x 20 = 80
200
If you mean 150 as a percentage of 200 then 150/200 times 100 = 75%
20
140 * 200 = 28,000
16 * 200 = 3,200
4 times 200 = 800
2.2 * 200 = 440
1 x 100 = 200 2 times 100 equals 200
30 times 200 times 1 is equal to 6,000.
The work done is equal to the change in potential energy, which is (m \cdot g \cdot h), where (m = 200) N and (w = 800) J. Solving for (h), we get: [800 = 200 \times 9.81 \times h] [h = \frac{800}{200 \times 9.81} = 0.408 , \text{meters high}].
200.
200 times 50 is 10,000 I think
