The result of the Nested absolute inequality  when resolved gives:
x = -10, 0. See the solution below.

It is to be noted that when one absolute-value expression is inside another one, this is called a "nested" expression. Absolute expressions are expressions that values that can NEVER be negative.

The solution hence is given as follows:

Given: ||x-5|4|≤1

One absolute-value expression is stacked inside another in this equation. I'll work from the outside in, sorting items into their respective cases. Assume the argument of the outer bars is negative (do the "minus" case):

Step 1 - first splitting:

|x-5| -4 ≤ -1
|x-5|  ≤ 3

I have to stop here since the last statement above states that an absolute value equals a negative number. Absolute values, on the other hand, are never negative! As a result, this step is invalid; it yields no viable solutions to the original problem.

Now I'll look at the scenario where the argument of the outside bars is positive (the "plus" case):

|x-5| -4 ≤ 1

|x-5|  ≤ 1 + 4

Recall that absolute values are never negative. This equation is correct, and I've isolated the leftover absolute value, so I'll go over the two situations again.

Step 2 - First, consider the "minus" case:

x+5  ≤ -5

x ≤ -5-5
x≤ -10

The variable can have a "minus" value; the sole constraint is that an absolute-value expression cannot have a "minus" value. Now consider the "plus" case:

⇒ x + 5 ≤ 5 again recall that this is an absolute expression hence the laws of polarity while cross the inequality sign is suspended.

x ≤ 5-5

x≤0

Hence the answer which is complete is:

x = -10, 0

We need to calculate the 10% of 20. By definition, a% is:

Where a can be any positive number. In this case a = 10, then:

In mathematics, the word "of" is reserved for the product. Then 10% of 20 is just:

Solving this leads to 2.

Answer:

50 percent.

Step-by-step explanation:

10 of 20 as a fraction is

10/20

- divide top and bottom by 10 and this simplifies to

1/2.

To convert to a percentage we multiply by 100:

= 1/2 * 100

= 50%.

The coordinates of the point X are (1 + 2, 6 - 1.25) = (3,4.75).

The segments, PX and XQ, have lengths in a ratio of 1: 2.

A line segment is partitioned when it is divided into equal parts according to a specified ratio. The total number of partitions of the line segment must be equal to the sum of the two values in the ratio.

Suppose you have a line segment PQ on the coordinate plane, and you need to estimate the point on the segment 1/3 of the way from P to Q.

Where P exists at the origin and line segment is a horizontal one.

The length of the line exists 6 units and the point on the segment 1/3 of the way from P to Q would be 2 units away from P, 4 units away from Q and would be at (2, 0).

The segment exists not a horizontal or vertical line:

The components of the directed segment PQ exists (6, 3) and we require to estimate the point, say X on the segment 1/3 of the way from P to Q. Then, the components of the segment PX exists [tex]$\left\langle\left(\frac{1}{3}\right)(6),\left(\frac{1}{3}\right)(3)\right\rangle=\langle 2,1\rangle$[/tex].

Since the initial point of the segment exists at origin, the coordinates of the point X exists given by (0+2, 0+1) = (2, 1).

where neither P nor Q exists at the origin.

Use the end points of the segment PQ to estimate the components of the directed segment.

[tex]$\left\langle\left(x_2-x_1\right),\left(y_2-y_1\right)\right\rangle=\langle(7-1),(2-6)\rangle \\[/tex]

= (6, -4)

The components of the segment PX where X exists a point on the segment 1/3 of the way from P to Q are

[tex]$\left\langle\left(\frac{1}{3}\right)(6),\left(\frac{1}{3}\right)(-4)\right\rangle[/tex]= (2, -1.25)

To estimate the coordinates of the point X add the components of the segment PX to the coordinates of the initial point P.

Therefore, the coordinates of the point X exists (1 + 2, 6 - 1.25) = (3,4.75).

The segments, PX and XQ, have lengths in a ratio of 1: 2.

Answer

Step 1:         6,3

Step 2:       x1  -1                     y2- 2

Step 3:           1, 7

Step-by-step explanation:

Using the probability concept, it is found that:

a) The tree diagram is given by the image at the end of the answer.

b) The probability is of 0.18 = 18%.

c) The probability is of 0.72 = 72%.

A probability is calculated as the number of desired outcomes in the experiment divided by the number of total outcomes in the experiment.

For item a in this problem, we have two independent events, hence the tree diagram will contain two nodes, one with each event and it's probabilities.

For item b, since the events are independent, to find the probability of both, we multiply the probability of each, hence:

0.3 x 0.6 = 0.18.

For item c, first we find the probability of none being completed, hence:

(1 - 0.3) x (1 - 0.6) = 0.7 x 0.4 = 0.28.

At least one is complementary to none, hence the probability is given as follows:

p = 1 - 0.28 = 0.72 = 72%.

The fraction of straight section of motor racing circuit is 3/14 miles.

To find the fraction of circuit which is straight, we will perform division. The fraction will be found as - Fraction = length of straight section ÷ total length of motor racing circuit

Keep the values in mentioned relation to find the fraction of circuit which is straight.

Converting the mentioned lengths from mixed fraction to fraction.

Length of motor racing circuit = (6×5 + 5)/6

Length of motor racing circuit = 35/6

Length of straight section of circuit = (4×1 + 1)/4

Length of straight section of circuit = 5/4

Fraction of straight circuit = (5/4)/(35/6)

56 small cubes can be placed in the given cuboid that has the given dimensions.

A cuboid's volume can be calculated using the formula below:

Volume of a cuboid = (length)(width)(height).

A cube has equal height, length, and width. Therefore, the volume of a cube is calculated as:

Volume of a cube = (side length)³.

The number of small cubes that can be placed in the given cuboid = volume of the cuboid/volume of one small cube.

Find the volume of the cuboid:

Length = 60 cm

Height = 54 cm

Width = 30 cm

Volume of the cuboid = (60)(54)(30)

Volume of the cuboid = 97,200 cm³

Find the volume of one cube:

Side length of one small cube = 12 cm

We need use this information and determine which lines in the figure are parallel.

We have been given angle 2 is supplementary to angle 3.

We know that, the sum of the angles on the same side of the transversal which are inside the two parallel lines is always 180°

Also, supplementary angles are the angles whose sum is 180°

The given equations (5b - 2)² + 4 = 25b²– 20b and (2x² + y²)(2x² - y²) = 4x² – y have been found not to be true identities

A) We want to check if (5b - 2)² + 4 = 25b²– 20b is a true identity.

A true identity is an equality that holds true regardless of the values chosen for its variables. They are used in simplifying or rearranging algebra expressions. By definition, the two sides of an identity are interchangeable, so we can replace one with the other at any time.

(5b - 2)² + 4 when expanded gives;

25b² - 20b + 4 + 4 = 25b² - 20b + 8

That is not equal to the right hand side and as such, we can say that both equations are not true identities

B) (2x² + y²)(2x² - y²) = 4x² – y
