Hello! I can help you with this!

a. Okay. So Reese has money to buy 115 cm of framing, with the length being 18.5 cm long. The formula would be written like this: 115 = 2(18.5) + 2w.

b. Now, let’s solve the problem. 18.5 * 2 is 37. 115 - 37 is 78. The width could be 78 centimeters or less. In inequality form, it would be written as this: w <= 78.

c. Now, graph the solution by writing a few numbers on the number line. Counting by 2’s, write the even numbers 70-86 on the number line. Put a closed circle point on 78, and then draw the line to the left. Going left means numbers are smaller and a closed circle means the equation is less than or equal to. The number line interprets that the width for both sides can total 78 centimeters or less.

Answer: 1.587 ounces of sodium chloride

Step-by-step explanation:

We know that 1 ounce is equivalent to 28.35 gr.

So we use this as a conversion factor to find the equivalent amount of sodium chloride in ounces.

If we need 45 grams of sodium chloride then this equals to:

45\ g* \frac{1\ ounces}{28.35\ gr} = 1.587\ ounces

Finally you need 1.587 ounces of sodium chloride

2. Continuous data are usually _____________________, but discrete data are usually ______________________.
Mrrafil [7]

Answer:

Measured and Counted.

Step-by-step explanation:

Continuous data are usually “Measured”, but discrete data are usually “Counted”.

The continuous data are the data that can be measured, for example, Height of children, time in the race, length of leaf, etc. In this case, the data is taken within the range. While the discrete data is the data that can be counted. For example, the number of employees in the office, the number of students in the school, the result of rolling dice, etc. In this case, the data is a fixed number. Accordingly, the continuous data is measurable and discrete data is countable.
