The compound inequality's solution set is represented by the symbol x. (2 , 6).
The compound inequality's answer is what?The intersection of the answers to each individual inequality is the answer to a compound inequality, which is a pair of inequalities connected by the word and. Alternatively put, both claims have to be accurate simultaneously.
The inequality is expressed as follows: 8x - 9 39 and 3.5x - 10 > -3.
Take one: 3.5x - 10 > -3
Then multiplying by 10 on each sides
⇒ 3.5x - 10 + 10 > -3 + 10
⇒ 3.5x > 7
the two sides are now divided by 3.5.
⇒ x > 2
Now, 8x - 9 < 39
On all sides, add 9.
⇒ 8x - 9 + 9 < 39 + 9
⇒ 8x < 48
then multiply both sides by 8 now.
⇒ x < 6
The compound inequality presented has the following solution set: x (2 , 6).

What is the additive inverse of − 5 − 7?
Answers
The additive inverse of − 5 − 7 is 12
The additive inverse of a number is the number that when added to the original number results in zero.
For example, the additive inverse of 5 is -5 because 5 + (-5) = 0.
In our question, the additive inverse of − 5 − 7 would be the number that when added to − 5 − 7 would give zero.
So, the additive inverse of -12 is 12 because -12 + 12 = 0
It is important to note that for any number 'a', its additive inverse is always -a. So if we take any number as a, its additive inverse will be -a.
In summary, additive inverse is the opposite of a number in terms of addition, and it is a number that when added to the original number it results in zero. and the additive inverse of -12 is 12.

Luke started a weight-loss program. The first week, he lost x pounds. The second week, he lost pounds less than times the pounds he lost the first week. The third week, he lost 1 pound more than of the pounds he lost the first week.
Liam started a weight-loss program when Luke did. The first week, he lost 1 pound less than times the pounds Luke lost the first week. The second week, he lost 4 pounds less than times the pounds Luke lost the first week. The third week, he lost pound more than times the pounds Luke lost the first week.
Assuming they both lost the same number of pounds over the three weeks, complete the following sentences.
Answers
The total weight lost by Luke and Liam each is 6 pounds
What is simplification of an expression?Usually, simplification involves proceeding with the pending operations in the expression. Like, 5 + 2 is an expression whose simplified form can be obtained by doing the pending addition, which results in 7 as its simplified form. Simplification usually involves making the expression simple and easy to use later.
Luke's weight loss journey;
Weight luke lost in the first week; x pounds
The weight he lost in the second week is 3/2 pounds less than 3/2 times the pounds he lost in the first week. Thus;
Weight luke lost in the second week = ³/₂x - ³/₂ pounds
In the third week, he lost 1 pound more than 3/4 of the pound he lost in the first week. Thus;
Weight luke lost in the third week = (³/₄x) + 1 pounds
Total weight lost by luke in 3 weeks = x + ³/₂x - ³/₂ + ³/₄x + 1
=¹³/₄x - ¹/₂
Liam's weight loss journey;
First week he lost 1 pound less than 3/2 times the pounds luke lost in the first week
Weight Liam lost in the first week; ³/₂x - 1 pounds
The weight he lost in the second week is 4 pounds less than 5/2 times the pounds luke lost in the first week. Hence:
Weight Liam lost in the second week = ⁵/₂x - 4 pounds
In the third week, he lost 1/2 pound more than 5/4 of the pound luke lost in the first week. Hence:
Weight Liam lost in the third week = (⁵/₄x) + ¹/₂ pounds
Total weight lost by Liam in 3 weeks = ³/₂x - 1 + ⁵/₂x - 4 + ⁵/₄x + ¹/₂
⇒ ²¹/₄x - ⁹/₂ pounds
uke and Liam lost the same weight over 3 weeks. Hence:
¹³/₄x - ¹/₂ = ²¹/₄x - ⁹/₂
⇒ ²¹/₄x - ¹³/₄x = ⁹/₂ - ¹/₂
⇒ 2x = 4
x = 4/2
x = 2
The expression for Luke's weight loss over the 3 weeks =
¹³/₄x - ¹/₂ pounds
The expression for Liam's weight loss over the 3 weeks =
²¹/₄x - ⁹/₂ pounds
The number of pounds Luke lost in the first week =
x = 2 pounds
The number of pounds Luke and Liam each lost over the three weeks = 6 pounds
Therefore, the total weight according to expression lost by Luke and Liam each will be 6 pounds

A metalworker has a metal alloy that is 20% copper and another alloy that is 70% copper. How many kilograms of each alloy should the metalworker combine to create 90 kg of a 60% copper alloy?
Answers
If a metalworker has a metal alloy that is 20% copper . The number of kilograms of each alloy should the metalworker combine to create 90 kg of a 60% copper alloy is: 18kg (20% copper), 72kg (70% copper).
How to find the number of kilograms?Let the amount of 20% copper be x kg. Since, total of 90 kg is needed, amount of 70% copper is 90-x kg .
So,
0.20x +0.70(90-x) = 0.60(90)
0.20x + 63 - 0.70x = 54
Combine like terms
0.50x =9
Divide both side by 0.50
x = 9/0.50
x = 18kg (20% copper)
Hence,
90-x
90 - 18 =72kg (70% copper)
Therefore the number of kilograms of each alloy is: 18kg (20% copper), 72kg (70% copper).

What is arithmetic progression ?
An arithmetic progression (AP) can be described in one of two ways:
A sequence known as an arithmetic progression has identical differences between each pair of terms in the sequence.
Arithmetic progressions are sequences where each term, with the exception of the first, is created by multiplying the previous term by a predetermined amount.
The formula for calculating the nth term of an arithmetic progression is expressed as:
Tn = a + (n + 1)d
where a is the first term, d is a common difference.
A linear function is described by the explicit formula below, where n is a positive integer.
f(n) = 5n +12
For the first term
f(1) = 5(1) + 12
f(1) = 17
For the second term
f(2) = 5(2) + 12
f(2) = 22
d = 22 - 17
d = 5
Therefore, a = an+1 + 5 is the recursive formula that expresses the same function.

A statement which best describes the function represented by the graph include the following: B) The function is decreasing on the interval (-∞, ∞).
What is a decreasing function?For any given function, y = f(x), if the output value (range or y-value) is decreasing when the input value (domain or x-value) is increased, then, the function is generally referred to as a decreasing function.
On the other hand (conversely), if the output value (range or y-value) is increasing when the input value (domain or x-value) is increased, then, the function is generally referred to as an increasing function.
By critically observing the graph above, we can reasonably infer and logically deduce that this function is decreasing over the interval -∞ < x < ∞, from left to right.

find the number of routers in the path at each of the two hours. did the paths change during any of the hours?
Answers
A test using traceroute command is performed to a destination site. The number of routers in this test is 8. The second test is performed after two hours and the paths does not change. In general case, the paths might change if there are network problems and it needs to do re-routing.
Traceroute is a command like ping command used for isolating problems in the network. Unlike ping command, traceroute does not need to know the IP address of the destination site.
The TTL (Time to Live) field in the IP packet header is used by Traceroute. TTL is typically used to prevent packets from being sent indefinitely when there is a routing loop. When a router forwards an IP packet, the TTL is reduced by one. When the TTL reaches zero, the IP packet is dropped.

the mean annual salary for environmental compliance specialists is about $66,000. a random sample of 35 specialists is selected from this population. what is the probability that the mean salary of the sample is less than $60,000? assume s
Answers
The probability that the mean salary of the sample is less than $60,000 is approximately 0.3576.
To calculate the probability that the mean salary of a random sample of 35 specialists is less than $60,000, we can use the central limit theorem which states that the mean of a large enough sample size from a population with a finite mean and finite standard deviation will be approximately normally distributed.
Given that the mean annual salary for environmental compliance specialists is $66,000 and we are taking a random sample of 35 specialists, we can assume that the sample mean will be approximately normally distributed with a mean of $66,000 and a standard deviation of [tex]$\frac{66,000}{\sqrt{35}}$[/tex]
To find the probability that the mean salary of the sample is less than $60,000, we need to standardize the value of $60,000 by subtracting the population mean and dividing by the standard deviation of the sample mean:
[tex]$z = \frac{60,000 - 66,000}{\frac{66,000}{\sqrt{35}}} = -0.537$\\[/tex]
Using a standard normal table or calculator, we can find the probability that a standard normal variable is less than -0.537. This probability is approximately 0.3576 or 35.76%.
So, the probability that the mean salary of a random sample of 35 specialists is less than $60,000 is approximately 35.76%.
It's important to note that this is an approximation and actual probability would be determined through experimental measurements.

Answers
The number of gallons to cover 4 walls will be 1.28 gallons
How to calculate the number of gallons?The walls are four in number. Each wall is rectangular in shape. The length of each wall is 14 feet and the height is 8 feet. A gallon of paint will cover an area of 350 square feet. For each wall, the area can be computed since the height and the length is known.
Area of each wall(rectangle) = Length × height
length = 14 feet
height = 8 feet
Area of each wall(rectangle) = 14 × 8
Area of each wall = 112 square feet
The total square feet is 112 × 4 walls
The total square feet of the 4 walls = 448 square feet
Since, 1 gallon will cover 350 square feet, the number of gallons will be:
= 448/350
= 1.28 gallons
