Mumz [18]

Step-by-step explanation:

well there is a very simple point that you have mistaken tho:

484cm², 25cm²

Areas are defined in square cm but the radius is in cm

so:

\sqrt{ \frac{484 {cm}^{2} }{25 {cm}^{2} } }  =  \frac{7.92}{r}  =  =  =  > 4.4 =  \frac{7.92cm}{x}  =  =  > x =  \frac{7.92cm}{4.4}  = x = 1.8cm

and there you go

PH is given by the formula pH = -log [H+]
Lunna [17]

Answer:

  • Maura's
  • 4 times

Step-by-step explanation:

The logarithm function is monotonic with a positive slope everywhere. So, the logs of numbers are in the same order as the numbers themselves. pH is the negative of the logarithm, so the pH values are in the reverse order of the numbers themselves.

Maura's pool has a lower pH, so will have a higher concentration of hydrogen ions.

The log of a ratio is the difference of the logs. Here, the difference of the logs is 7.8 -7.2 = 0.6, so the ratio of H+ concentrations in the two pools is ...

  10^0.6 ≈ 4.0

Maura's pool has 4× the H+ concentration of Bill's pool.

AfilCa [17]

3rd egg:45.07

5th egg:46.3

Hope this helps!
