A sphere with diameter 1 unit is enclosed in a cube of side 1 unit each. Find the unoccupied volume remaining inside the cube.

We find the volume of the cube by the formula length^3. We then subtract from it the volume of the sphere to find the empty volume. The volume of cube amounts to 1*1*1=1. The volume of the sphere is (4/3)* π *(radius)^3. Putting in the values we get (4/3)* π *(0.5) ^3. This is equal to pi/6. Subtracting the two gives 1- π /6.

Alan has two more than twice as many chocolates as does Alice, and half as many chocolates as does Nadia. If Alice has 'a' number of chocolates, then in terms of 'a', how many chocolates do Alan, Alice and Nadia have?

We know that Alice has 'a' chocolates. Alan has 2a+2 chocolates from the given statement in the question. Nadia has double the chocolates as Alan has, so she has 4a+4 chocolates. Adding these, we get 4a+4+2a+2+a = 7a +6

Milk needs to be thinned to a ratio of 3 parts milk to 2 parts water. The milk-man has by mistake added water so that he has 8 liters of milk which is half water and half milk. What must he add to make the proportions of the mixture correct?

We note that the final ratio must be 3:2 for milk and water respectively. Now, according to given scenario in the question, we have eight liters of solution with 4 liters milk and 4 liters water, which makes it 2:2. In order to make it 3:2, we add 2 liters milk. This would make a total of 6 liters milk and 4 liters water i.e. 6:4 which can be simplified to 3:2.

As the given line is parallel to the y-axis, and the slope of y-axis is infinite, therefore its slope is also infinite. As the line is defined by x=2, hence its x intercept will also be 2 because all of its points will be of the form (2,y).
