Answer:
Option A.
Step-by-step explanation:
Definition of Boyle's law: a law stating that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature. There is thus a relationship between volume and pressure of the gas thus option B and C are incorrect.
To get the answer to this problem, first we have to subtract the marked up cost to the cost of the product. So we first minus 25.3 and 22.25. When we do this, we will get a difference of 3.05. This is the profit that you will earn. So after that, we have to divide 3.05 and 25.30 to get the mark up percentage. When we do this, we will get an answer of 0.12. So in order to convert that into a percentage, we just have to multiply it by 100 and we will get 12%.
W=2L
P=300=2(L+W)
so
300=2(L+W)
divide by 2
150=L+W
W=2L
subsitute
150=L+2L
150=3L
divide by 3
50=L
sub back
W=2L
W=2(50)
W=100
the field is 100yd wide by 50yd long
It has no solution. The statement is false for any value x and y therefore the system of equations has no solution.
