A is the answer
divide 0.5/ 0.1
The correct answer is C. A statement we accept
without proof is called a postulate. It is also known as an axiom. These are rules
which are accepted to be true without any evidence that will prove these. For
instance, the postulates in the kinetic molecular theory.
Answer:
x is mL of 25% acid and y is mL of 50% acid
We set up 2 equations:
A) x + y = 250
B) .25 x + .50y = .35 * 250 which equals
B) .25x + .50y = 87.50 Multiplying A) by -.5
A) -.5x -.5y = -125 adding the equations we get
-.25x = -37.50
x = 150 mL
y = 100 mL

Step-by-step explanation:
The answer you eliminated is the right answer which is A
The other rest are wrong because 5x5=25 and 5x5x5=125 if you times both of thos you should get 3125 and A 5x5x5x5x5=3125 Btw i used a calculator.
The answer to your question is 5.4
