3. pH is given by the formula pH = -log [A]

1 answer:

5 0

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

5 is what percentage of 25? I’ll give brainliest:)

Hi there! :)

To solve, we can simply divide and multiply by 100 to solve for the percentage:

5 / 25 = 5 ÷ 25 = 1/5 or 0.20

Multiply the decimal by 100 to solve for the percentage:

0.20 × 100 = 20%

How do i conjugate the binomial<br><img src="https://tex.z-dn.net/?f=%20%5Csqrt%7B6%20%2B%204%7D%20" id="TexFormula1" title=" \s

We solve 6 + 4

6 + 4 = 10.

Square root of 10:

$\boldsymbol { \sqrt{6 + 4} = \sqrt{10} }\\
\\
\\
\boldsymbol { \sqrt{10}l\underline{ \ 3.16227766017}}\\
\boldsymbol { \underline{- 10}l \ 3.16227766017 \times 3.16227766017 }\\
\boldsymbol { \ \ \ 00}$

<span>The square root of 10 is a periodic decimal (decimal that has infinite decimals, worth the redundancy)

What is that periodic decimal?
</span>
$\boxed{\textbf{3.16227766017} \boldsymbol{ \ \Leftarrow }\textbf{Square root of 10}}$
