Roberto has twice the mass his sister Mary has but runs at the same velocity as Mary. Will his kinetic energy be twice as much?
(Mary has a mass of 40 kg and sprints at 1 m/s)
Can someone help me with this (sorry I don’t have enough point for a question and no one has answered this and I’m confused)
Since 450 is less than 500 you would leave it at 10,000
HI + IJ = HJ
=> x + 12 + 16 + x = 20
<=> 2x + 28 = 20
<=> 2x = -8
<=> x = -4
with x = -4 => HI = - 4 + 12 = 8

Answer:
23/24
Step-by-step explanation:
7/8 + 1/12
We need a common denominator
Both 8 and 12 go into 24
7/8 *3/3 = 21/24
1/12 *2/2 = 2/24
21/24 + 2/24
23/24
We are going to take 132 divided by 6, because there are 6 different rolls he can get. So, 132/6=22
