Tetrahedron generally known as triangular pyramid consists of 4 triangular faces, 6 edges and 4 vertices. The base of the tetrahedron is a triangle. All the vertices have the same atom that is bonded to the central metal atom which lies in the centre of the tetrahedron. We take as an example to see how the atoms actually bond in tetrahedron. It is quite visible from the image that 4 O-atoms lies on all the 4 vertices and 1 Si-atom lie in the centre.
Explanation:
In order to justify Marian's statement we have to look at the '' Amount per serving calories'' ⇒
In food label A we can see that this value is 160 calories
In food label B we can see that this value is 50 calories
⇒ 160 calories is slightly more than three times 50 calories
Otherwise If we want to justify Johan statement we need to look at the '' serving size '' ⇒
In food label A we can see that the serving size is 1 cup (237 mL)
In food label B we can see that the serving size is cup (56g)
Working with the information of the food label A we can write the following expression :
⇒ Looking at the value of ''
'' ⇒
If we look at the same amount of portion volume :
In cup of food A we have 40 calories
In cup of food B we have 50 calories
We could conclude that Food B has more calories.
That's how both claims could both be justified.
