Answer
The steel ball will be caught up in between the mercury and water medium.
Step-by-step explanation:
- Mercury with a density of 13546 kg/m^3
- water with a density of 1000 kg/m^3
- Steel with a density of 8050 kg/m^3
From the factual density of both substances given above ,it shows that mercury is more heavier than water. In that case mercury will be at the lower layer when mixed with water.
The steel ball will be caught in between both mixtures as the density of steel is 8050 kg/m^3.Which is more than Water but less than Mercury.
So you are given that 45 people in the age range of 18 to 29 who voted make up 10% of the total voters.
And you also know that 30% of the voters are in the age range of 30-49. And you need to find out how many people aged 30-49 voted.
So 10% of the total make up 45 people.
That means for 30% of the total number people, there would be 45 x 3 people, or 135 people. Because 10% x 3 = 30%
So, great job! :D
