Answer:

Step-by-step explanation:

Solubility refers to how well a solute (which can be a solid, liquid, or gas) can dissolve in a solvent to form a solution. There are several factors influencing solubility, with the main four being temperature, polarity, the surface area of the solute, and gas pressure. Typically, increasing temperature enhances the solubility of a solute in a solvent. This occurs because higher temperatures elevate the average kinetic energy of the solution's molecules, leading to better interaction between solute and solvent particles. The phrase "like dissolves like" is often used when discussing issues related to polarity; for instance, organic solvents effectively dissolve organic solutes, demonstrated by using petrol for greasing hands or surfaces. Therefore, if both solute and solvent share the same polarity, solubility happens readily; otherwise, it may be challenging or impossible. A decreased surface area of the solute increases solubility, as it facilitates easier interactions between the solute and solvent. In the case of gases, increased pressure enhances the interaction between gaseous solute molecules and solvent, thus improving solubility, while pressure has minimal effects on solids and scarcely affects liquids.

Answer:

The price per kilogram of salami amounts to = $9.1

Step-by-step explanation:

Given:

Hailey spent $13 on $1\frac{3}{7}$ kg of sliced salami.

We need to determine the cost per kg of the salami.

Solution:

We will use the unitary method to find the cost for one kilogram of salami.

If $1\frac{3}{7}$ kg of salami costs $13

Then the cost for 1 kg of salami in dollars = $13\div 1\frac{3}{7}$

When dividing mixed numbers, we convert them to fractions.

⇒ $13\div \frac{(7\times1)+3}{7}$

⇒ $13\div \frac{10}{7}$

To divide fractions, we take the reciprocal of the divisor and multiply.

⇒ $13\times \frac{7}{10}$

⇒ $\frac{13\times7}{10}$

⇒ $\frac{91}{10}$

⇒ $9.1$

Hence, the cost per kilogram of salami is = $9.1

I have a past due balance of $87.50 and my new charges are $75.00. I was also charged a late fee of 15% of my past due balance.

PIT_PIT [3919]

Past due amount = $87.50
Late fee equals 15% of $87.50, which is 0.15 × 87.50 = $13.125
New charges are $75.00

Total due now = 87.50 + 13.125 + 75 = $175.625

Final total: $175.63
