X and y values written in the form (x, y)
Answer:
Max: Victor: Roman
6: 3: :9
Step-by-step explanation:
Max: Victor: Roman
3 : 2 : 4
Take away 1/4 of 2
1/4 of 2 =
1/4*2 = 1/2
2-1/2 =
4/2 - 1/2 = 3/2
Victor now has 3/2
Roman gets 1/2 so he has
4+ 1/2
8/2 + 1/2 = 9/2
Max: Victor: Roman
3 : 3/2 : 9/2
But we normally don't leave fractions in the ratio's
Multiply each number by 2 (the ratio won't change)
3*2 : 3/2*2 : 9*2
6: 3: :9
To find the percentage,here's what we can do:
The percentage would then be:
=63/420×100%
=3/20×100%
=0.15×100%
=15%
Therefore the answer is 15%.
Hope it helps!
KE = 0 (because velocity is 0)
PE = mgh = 2kg*9.8m/s^2*40m= 784 joule
<u>Explanation:</u>
KE stands for kinetic energy. In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. Since in this case, the building is still and therefore it does not have any kind of kinetic energy because there is not acceleration.
