Hey!!
here is your answer >>>
Let's take the total amount as 'X'
Then,
(40/100)X = 24
2x /5 = 24
x = (24*5)/2
x = 12*5
x = 60!.
100% is 60
Hope my answer helps!
Answer:
the Kinetic Energy of the marble at the later point is 0.0007 J
Step-by-step explanation:
Given;
initial potential energy of the marble, P.E₁ = 0.0018 J
final potential energy of the marble, P.E₂ = 0.0011 J
At the initial starting point, the total mechanical energy is;
M.E = K.E + P.E
at the initial starting point, velocity = 0
M.E = 0 + P.E
M.E = P.E = 0.0018 J
At some point later, the total mechanical energy is;
M.E = P.E + K.E
0.0018 J = 0.0011 J + K.E
0.0018 J - 0.0011 J = K.E
0.0007 J = K.E
Therefore, the Kinetic Energy of the marble at the later point is 0.0007 J
B. 94 because it is the same as the other one
Answer:
m = 21
Step-by-step explanation:
12 = 3(m - 17)
12 = 3m - 51 (Found using the distributive property)
63 = 3m (Found by adding 51 to both sides)
21 = m (Found by dividing both sides by 3)
Hope this helps :)
It would be 
, or, in simplest form, 
.
You get this by adding all the marbles to find the total number of marbles. <em>10+7+12+9</em>, which equals <em>38</em>.
You have <u>10 red marbles out of 38 total</u>, so that is represented by !
