According to the text, the largest single expense in most organizations is:
The text explicitly states that the largest single expense in most organizations is labor cost, which is often considerably higher than necessary due to problems like absenteeism, tardiness, and discrimination. This makes effective HRM critical for cost management.
How many litres of water must be added to 1 litre of a pH 1 HCl solution to raise the pH to 2?
pH 1 means $[\text{H}^+] = 0.1\ \text{M}$; pH 2 means $[\text{H}^+] = 0.01\ \text{M}$.
Using dilution formula $C_1V_1 = C_2V_2$:
$0.1 \times 1 = 0.01 \times V_2$
$V_2 = 10\ \text{L}$
Volume of water to add $= V_2 - V_1 = 10 - 1 = \mathbf{9.0\ \text{L}}$
Let $n$ be a positive integer divisible by 6. Compare:
Quantity A: The remainder when $n$ is divided by 12
Quantity B: The remainder when $n$ is divided by 18
Since $n$ is divisible by 6, $n$ can be $6, 12, 18, 24, 30, 36, \ldots$
Example 1: $n = 12$. Remainder รท12 $= 0$. Remainder รท18 $= 12$. B > A.
Example 2: $n = 18$. Remainder รท12 $= 6$. Remainder รท18 $= 0$. A > B.
Example 3: $n = 36$. Remainder รท12 $= 0$. Remainder รท18 $= 0$. Equal.
The relationship changes, so it cannot be determined.
