Answer:
The volume of the triangular prism is 5676.16 cm³
Step-by-step explanation:
The area of the triangular base A = bh/2 where b = base = 28 cm and h = height = 22.4 cm.
Now, the volume of the triangular prism, V = area of triangular base, A × height of prism, h'
V = Ah' where h = height of prism = 18.1 cm
So, V = bhh'/2
Substituting the values of the variables into the equation for V, we have
V = bhh'/2
V = 28 cm × 22.4 cm × 18.1 cm/2
V = 14 cm × 22.4 cm × 18.1 cm
V = 5676.16 cm³
So, the volume of the triangular prism is 5676.16 cm³
Answer:
77 centigrams = .077 decagrams
Step-by-step explanation:
Because 1 centigram = .001 decagram
The average of the first three is 83 (85 + 90 + 74)/3
The average of the next 3 is 86.
The difference is 3
Answer:
Applying the scientific method by having two control groups.
Step-by-step explanation:
Margaret´s design supports its conclusion because she applied the scientific method.
Margaret had two control groups: the ones that play videogames only a little and the ones who play a longer time.
She tested both groups and made an estadistic manner to show the results.
By this way she supported her conclusion.
If something she did wrong id that she didn´t had an hipothesis to base of.
