Abuilding casts a shadow 48 ft long. at the same time, a 40 ft tall flagpole casts a shadow 9.6 ft long. what is the height of the building?

It is given in the question that

A building casts a shadow 48 ft long. At the same time, a 40 ft tall flagpole casts a shadow 9.6 ft long.

Let the height of the building is h ft .

Now we take ratios and solve for h. That is

Performing cross multiplication,

Dividing both sides by 9.6

Therefore the height of the building is 200 ft .

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
