Answer:

The pH of the clean compound is approximately 10.495.

Step-by-step explanation:

If the cleaning ion concentration of the cleaning compound is [H^{+}] = 3.2\times 10^{-11}, then the pH, no unit, of the compound is:

pH = -\log_{10} [H^{+}]  (1)

pH = -\log_{10} (3.2\times 10^{-11})

pH = -\log_{10} 3.2 - \log_{10} (10^{-11})

pH = -\log_{10} \frac{32}{10} +11

pH = -\log_{10} 32 + \log_{10} 10 + 11

pH = -\log_{10} 32 +12

pH \approx 10.495

The pH of the clean compound is approximately 10.495.

vazorg [7]
Hello! A way we could solve this equation is to divide 714 by three and then multiply the quotient by 2 to get the number of men that attended. 714/3 is 238. There were 238 women that attended the concert. 238 * 2 is 476. 476 + 238 = 714. There. There were 476 men that attended the concert.

A homemade loaf of bread turns out to be a perfect cube. Five slices of bread, each 0.6 inch thick, are cut from one end of the
erastovalidia [21]

A cube has all sides of equal length.

So let the side be x

that will be length = width = height = x  

Now, when we cut the loaf into 5 equal slices, the length and height of the slices are the same as the original loaf.  But the width will become less with each slicing. Here the width corresponds to the thickness of the slices.

For each slice the dimensions are -

Length = x

height = x

width = 0.6

Volume of the original loaf is x³.

Volume of  5 slices is 5(x * x * 0.6).  

Volume that is left after the cutting the slices is 235 inch³.

So, equation of the volume is=

x³ - 5(0.6x²) = 235

Solve for x using this equation.

x³ - 3x² = 235

x³ - 3x² - 235 = 0

Using a graph calculator to find the roots, we get

x = 7.35

Hence the dimensions of the original loaf is 7.35 inches for each side.

Please find attached the graph.
