The inequality can be:
Now you divide both sides by 150 to get the #of boxes.
Lastly, x is 20. So the maximum amount of boxes that the freight elevator can hold is 20
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
You can write this as a proportion
inch over miles = inch over miles
1/14.5 = 4.5/x
cross multiply
x = 65.25
They are actually 65.25 miles apart.
Hope this helps

Answer:
21
Step-by-step explanation:
First, we would find 30% of 30, which would be 9. Then we would subtract 9 from 30 because we are decreasing it by 30%. That means the answer is 30-9, which is 21.
