Answer: The kinetic energy of Derek's bike is 384.
To find the kinetic energy of an object, we need to know the mass and the velocity of the object. Both of those are already given in the problem. So we can simply use the formula.
The formula for kinetic energy is KE =0.5(m)v^2. All we need to do is input the know variables and evaluate.
KE = 0.5 (12) (8^2)
KE = 0.5(12)(64)
KE = 384
That’s really nice man. I’m sure she’ll love it

Answer:
5/9
Step-by-step explanation:
Let the total number of buttons is x.
- Round buttons = 80% of x = 0.8x
- Square buttons = 0.2x
<u>Number of red buttons:</u>
- 0.1*0.8x + 0.5*0.2x =
- 0.08x + 0.1x =
- 0.18x
Number of red square buttons is 0.1x
<u>Required probability:</u>
- P = 0.1x/0.18x = 10/18 = 5/9
