The answer is 296 hope it helps
Answer: [H+] = 10^-7.2
Step-by-step explanation:
Given that the PH of the solution = 7.2
Using the formula pH = –log[H+]. To get the H+ concentration from the pH, raise both sides by the base of 10. Then we have
10^ -pH = H+. with pH of 7.2,
Thus the answer to this problem is
[H+] = 10^-7.2
Answer:
a∈(-∝;-17)∩(11;+∝).
Step-by-step explanation:
|a+3|>14; ⇔ 14<a+3<-14; ⇔ 11<a<-17;
Let's figure this out! Okay, so the original price is 24. 45% is taken off. Well, we just multiply 24 and 0.45! (45% = 45/100 = 0.45) When we do that, we get 10.8. Now, a common mistake is to just say 10.8 is the answer. Unfortunately for Charlie, that is only how much is being taken off. If 10.8 is being taken off 24, we subtract. 24 - 10.8 = 13.2. And there we have it!
Charlie payed $13.2.
Hope this helps!
