Answer:

67.89 is rational

Step-by-step explanation:

67.89 is a terminating decimal, so it is a rational number.

Each pound has 16 ounces in it.

20 pounds would be 16 x 20 ounces = 320 ounces.

If each bag has 5 ounces in it, that's 320 / 5 bags = 64 bags.

When we do Matrix multiplication, we keep these two conditions in mind: 1 The number of columns of the first matrix in the multiplication process must equal the number of rows of the second.

here  number of columns of 1st matrix is not equal to number of rows of 2nd matrix.

To multiply two matrices, we must first determine if the first matrix's number of columns and rows equals the second matrix's number of rows. Then sum all of the results after multiplying each element of the first matrix's column by each element of the second matrix's row.

In dealing with many ideas in linear algebra, matrices are crucial. In mathematics, a matrix is a rectangular array or table with rows and columns of integers, symbols, or expressions. Matrix operations include addition, subtraction, multiplication, and other operations.

The value of "x" in the given figure and question is 20 units.

As per the question statement, We are given a figure in which we are supposed to find the value of x.

Before solving the question, if we observe the figure, we can conclude that this question will include the concepts of right angled triangle or specifically Pythagoras Theorem, which states that

[tex]Perpendicular^{2} + base^{2} = hypotenuse^{2}[/tex] where perpendicular, base and hypotenuse are the three sides of the right angled triangle.

In Triangle RTQ

using Pythagoras Theorem

[tex]RQ^{2} = TQ^{2} +TR^{2} \\RQ=x\\x^{2} = 16^{2} + TR^{2} \\TR^{2} = x^{2} -16^{2}[/tex]

Now considering triangle SRT

using Pythagoras Theorem

[tex]SR^{2} = RT^{2} + ST^{2} \\SR^{2} = (x^{2} -16^{2}) +9^{2}\\[/tex]

Now considering triangle RSQ

using Pythagoras Theorem

[tex]SQ^{2} = SR^{2} +RQ^{2} \\(9+16)^{2} = SR^{2} + RQ^{2} \\(9+16)^{2} = x^{2} -7^{2}+x^{2} \\ (9+16)^{2} =2x^{2} -7^{2} \\25^{2}+7^{2} = 2x^{2}[/tex]

[tex]2x^{2} =674[/tex]

[tex]x^{2} =337\\x=\sqrt{337} \\x=18.357[/tex]

Therefore x = 18.357 approx 20 units.

To solve the inequality, subtract 8 from both sides. The solution is t ≥ 11 or [11, ∞)

Tips to solve linear inequalities:

Interval notation is often used for the solution(s). Recall the differences between a bracket [ or ], and a parenthesis (  or ). A bracket means the endpoint is included in the solution while a parenthesis means the endpoint is not included in the solution. Remember, infinity ∞ always use a parenthesis.

Example:  x ≥ 2 can be written as [2, ∞), while

                x > 0 is written as (2, ∞)

The given problem:

t+8 ≥ 19

Subtract 8 from both sides. Subtracting a number from both sides will not change the inequality. Hence,

t+8 - 8 ≥ 19 - 8

t ≥ 11

Using the interval notation, the solution is [11, ∞)

The total weight of two animals in scientific notation is 1.3 x 10⁴ lbs.

Scientific Notation:

A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

For example,

650,000,000 can be written in scientific notation as 6.5 ✕ 10⁸.

Given,

The approximate weights of two animals are 4.23 x 10³ lbs. and 8.7 x 10³ lbs.

Here we need to find the total weight of the two animals and we need to write the final answer in scientific notation with the correct number of significant digits.

The total weight of the two animals is calculated as

Total weight = Animal 1 + Animal 2

So,

Total weight = 4.23 x 10³ lbs + 8.7 x 10³ lbs.

Take 10³ lbs as the common term,

Then we get,

Total weight = (4.23 + 8.7) x 10³ lbs.

Total weight = 12.93 x 10³ lbs.

It can we rewritten as,

Total weight = 1.293 x 10⁴ lbs.

When we round off it, then we get,

Total weight = 1.3 x 10⁴ lbs.

Hence, the total weight of the two animals is 1.3 x 10⁴ lbs.

The value of x of the first rectangular deck is 8.

For given question,

The perimeter of a one rectangular deck is 78 feet.

The length of the first rectangular deck is  represented as (2x + 3), and its width is represented as (3x-4).

Similarly, the perimeter of a second rectangular deck is 2 times the perimeter of the first deck with a length of (4x + 6) and a width of (6x -1).

We need to find the value of x of the first rectangular deck.

Let P1 be the perimeter of the first rectangular deck.

⇒ P1 = 2 × (length + width)

⇒ 78 = 2 × [(2x + 3) + (3x - 4)]

⇒ 39 = (2x + 3x + 3 - 4)

⇒ 39 = 5x - 1

⇒ 40 = 5x

⇒ x = 40/5
