if the ratio of the ages of kisii and esinam is 3:5 and that of Esinam and Larry is 3:5 and the sum of the ages of all three is
larisa [96]

Answer:

The age difference between the oldest and the youngest is 48.

Explanation:

Given the following data;

The ratio of the ages of Kisii (K) and Esinam (E) is 3:5.

The ratio of the ages of Esinam (E) and Larry (L) is 3:5.

The sum of the ages of all three is 147.

Since the age of Esinam is common in both ratios, we find the lowest common multiple (LCM);

LCM of 3,5 = 15.

Hence, the ratio of the three ages is now;

K:E:L = 9:15:25

Let their ages be denoted by x;

K:E:L = 9x:15x:25x

The sum of all three ages is;

9x + 15x + 25x = 147

49x = 147

x = 147/49

x = 3.

To find the age difference between the oldest and the youngest;

The oldest is Esinam = 25x

The youngest is Kisii = 9x

Therefore, 25x - 9x = 16x

Substituting the value of x, we have;

x = 3; 16x = 16(3) = 48.

The age difference between the oldest and the youngest is 48.

Have your ideas about what happens to molecules in the liquid, solid, and gas phase changed? If so, how? What evidence supports
Westkost [7]

Various states of matter have molecules moving at different velocities.

<h3>Molecules in matter</h3>

Matter is composed of molecules. These molecules that compose matter are in constant random motion. The kinetic energy and velocity of the molecules depends on the state of matter.

Molecules of a gas are fastest followed by molecules in a liquid. Molecules in a solid do not move at all hence solids have a definite shape.
