If a scientist finds a foramina on a bone sample, they can conclude that the bone belonged to a vertebrate animal, as foramina are small openings or holes on bones that allow nerves and blood vessels to pass through. These openings are essential for the transportation of oxygen and nutrients throughout the body, and their presence indicates that the animal had a complex system of blood vessels and nerves. The size and shape of the foramina can also provide information about the size and type of blood vessels and nerves that were present in the animal.
Furthermore, the location of the foramina can provide clues about the function of the bone and the animal's lifestyle. For example, if the foramina are located near the joints, it suggests that the animal had a highly mobile joint and needed a good blood supply to keep the joint healthy. If the foramina are located near muscle attachments, it suggests that the animal had strong muscles that required a lot of oxygen and nutrients.
In conclusion, the presence of foramina on a bone sample can tell a scientist a great deal about the animal that the bone belonged to, including its classification, physiology, and lifestyle.

Find an expression for the area of the shape shown below. Give your answer in its simplest form. 7x 14 10 4x Not to scale
The expression for the area of the above compound shape is 62x. See the solution below.
First we reduce to compound shape to simple shapes. This becomes,
One Triangle and
One rectangle
recall that the area of a triangle is (b x h)/2
while that of a rectangle is l x w
so we have
Triangle = (3x * 4)/2 = 6x
Rectangle = 4x * 14 = 56x
Thus,
Triangle + Rectangle = 6x + 56x = 62x
Thus, the expression for the area of the shape is 62x.

Fig. 15.20 shows a composite solid consisting of a cube of edge 28 cm and a square-based pyramid of height 16 cm. Calculate the volume of the solid.
The volume of the composite solid consisting of a cube and a square-based pyramid is 26,099.2 cm³.
How to calculate volume?Calculate the volume of the cube and the pyramid separately.
The volume of the cube is given by V_cube = s³ = 28³ = 21,952 cm³.
The volume of the pyramid is given by V_pyramid = (1/3)Bh, where B = area of the base and h = height of the pyramid.
The base of the pyramid is a square with sides equal to the base of the cube, so
B = s² = 28² = 784 cm².
Thus, V_pyramid = (1/3)(784)(16) = 4,147.2 cm³.
The total volume of the composite solid is the sum of the volumes of the cube and the pyramid, so
V_total = V_cube + V_pyramid = 21,952 + 4,147.2 = 26,099.2 cm³.
Therefore, the volume of the solid is 26,099.2 cm³.
