Answer: Ratio as a fraction in simplest form is :

Step-by-step explanation:
Since we have given that
10.8 seconds : 36 feet
As we know that

So, we use it :
10.8 seconds : 36 feet

Hence, Ratio as a fraction in simplest form is :

Answer:
Rectangular Prism
Step-by-step explanation:
We usually see building shaped as a 3D rectangle. If this is the type of building you are talking about, we use a rectangular prism in order to build the building with correct measurements.

Answer: B) hyperbola</h3>
If the cutting plane was parallel to the circular base of the cones, then we would have a circular cross section (assuming the plane doesnt cut through the vertex). However, we're told than the plane intersects both nappes, or cones, so it's not possible for the plane to be parallel to the base faces. We can rule out choice A.
We can rule out choice C and choice D for similar reasons. An ellipse only forms if the plane only cuts through one cone only, which is the same story for a parabola as well.
