Well, what I’d do is just see who has the most which is Bill and then for the other question I’d just subtract 7.8 - 7.2 which is equal 6 so the pH is greater by .6
Answer:
The answer is 1/9.
Step-by-step explanation:
When solving for the slope of a perpendicular line to a given, you have to flip the opposite reciprocal.
First take the number and flip the reciprocal, in this case -9 turns into -1/9.
Then flip the sign, like making a negative to a positive or a positive to a negative. In this case make -1/9 into 1/9
Therefore the answer is 1/9.
Your answer is going to be
23% :)
Ok so she has to pay 30 percent more of the 20 dollars she already has to pay because of the tax and then the tip so you multiply 20 by .30 which is six then you add that to 20 which is 26
