Two triangles that are similar figures has equal and ratio of corresponding sides.Also, the corresponding angles of two similar triangles are equal. We can solve this problem using this principle.
AB/DE=BC/EF=CA/FD
As well as the corresponding angles are equal.
∠ABC=∠DEF
∠BCA=∠EFD
∠CAB=∠FDE
Solution
Given data
According to Boyle's law, PV = K
The required general equation thus is
Substituting these values we find that the initial pressure is
The initial pressure to the nearest tenth, therefore, is 1.8 atm.
The final answer, therefore, is Option D
15 is the awnser too this one
Let (1/3)x + 2 = (4/3)x-5
-> x + 21 = 4x
-> 3x = 21
->x = 7
So y = 7/3+2 = 13/3
Answer is (7, 13/3)
