Making a table helps compare two or more sets of data because you can look at how much it has increased or decreased.

Answer:

<em>Tables are essentially the source for all the charts. They are best used for comparison, composition, or relationship analysis when there are only few variables and data points. </em>It would not make much sense to create a chart if the data can be easily interpreted from the table.

The tables help us to compare the values of those two sets of the data that have been presented in different ways.

4. Add one set of parentheses to make the expression equal

Sauron [17]

The expression that is equal to 2022 by adding a set of parentheses is 12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (12 /12 + 12 / 12).

<h3>How to solve a long-expression problem?</h3>

In mathematics, parentheses are used to group a set of mathematical terms. In a long-expression, like the one presented, using parenthesis implies:

The terms in the parentheses are solved separately from those outside the parentheses.
The terms in the parentheses are solved before solving those outside.
Moving the parentheses will affect the result of the whole expression.

Based on this, the expression that equals 2022 is:

12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (12 /12 + 12 / 12)

<h3>Let's solve it to prove this result</h3><h3 />

12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (12 /12 + 12 / 12)

First, solve the parenthesis first by dividing and then by adding.

12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / (1 + 1)12 x 12 x 12+ 12 x 12+ 12 x 12 + 12 / 2

Now, let's solve this expression, the first step is to solve the multiplications.

1728 + 144 + 144 + 12/2

Now, solve the division.

1728 + 144 + 144 + 6

Finally, add everything.

1728 + 144 + 144 + 6 = 2022

A blank CD can hold 70 minutes of music. So far you have burned 25 minutes of music onto the CD. You estimate that each song las

zaharov [31]

Answer:

The possible numbers of songs that you can burn onto the CD is 11.

Step-by-step explanation:

The total storage capacity of CD = 70 minutes

Storage already used = 25 minutes

Hence, The available storage = Total available storage - Used Storage

= 70 minutes - 25 minutes = 45 minutes

Hence, the CD has 45 minutes storage left.

Now, each song takes up 4 minutes of storage.

⇒ $\textrm{Total number of songs possible} = \frac{\textrm{Total storage left}}{\textrm{Time taken by each song}}$

= $\frac{45 minutes}{4minutes } = 11.25$

⇒The number of songs possible = 11.25 ≈ 11

Hence, the possible numbers of songs that you can burn onto the CD is 11.

A square piece of paper has an area of x2 square units. A rectangular strip with a width of 2 units and a length of x units is c

vlabodo [156]

Let

x--------> the length side of the original square paper

we know that

<u>the area of the original square paper is equal to</u>

$A1=x*x=x^{2} \ units^{2}$

<u>the area of the remaining piece of paper is equal to</u>

$A2=x^{2} -2x\\ A2=120\ units^{2} \\ so\\ x^{2} -2x=120\\ x^{2} -2x-120=0$

therefore

<u>the answer is the option </u>

x2 − 2x − 120 = 0

What is the measure of ∠1 in the trapezoid?<br><br><br><br> 130°<br> 105°<br> 75°<br> 25°

Nata [24]

It is bigger than 50, so 25 is out. It is smaller than 105, so 105 and 130 are out. That leaves 75. Process of elimination. I hope this helps.
