The answer would be negative 6 or -6.
Hope this helps!
The values for N can be any number between and including -6 and 6, because the phrase 'N is less than 6 units from 0' signifies absolute distance from zero on the number line.
Explanation:In mathematics, when we say 'N is less than 6 units from 0', we are referring to absolute distance from zero on the number line. That means, N could be any number that falls within the range of -6 to 6, inclusive. This is because the less than 6 units from zero is referring to both directions on the number line. For example, -4 is less than 6 units away from 0, also 5 is less than 6 units away from 0. Thus, the possible values for N are any numbers between and including -6 and 6.

Solve for r.
K = 8r-s
To solve for r in the equation K = 8r - s, add s to both sides of the equation and divide both sides by 8, resulting in r = (K + s)/8.
Explanation:To solve for r in the equation K = 8r - s, we need to isolate r.
We can start by adding s to both sides of the equation to get K + s = 8r.
Then, we divide both sides by 8 to solve for r.
The final equation is r = (K + s)/8.

(1, 9)
(−1, 7)
Answer: Second option.
Step-by-step explanation:
Given the function f(x):
[tex]f(x) = x^2 - 2x + 8[/tex]
Find [tex]f(x -2)[/tex]:
[tex]f(x -2)=(x-2)^2 - 2(x-2) + 8[/tex]
Remember that:
[tex](a\±b)^2=a^2\±2ab+b^2[/tex]
Then, simplifying:
[tex]f(x -2)=x^2-2(x)(2)+2^2 - 2x+4+ 8\\\\f(x-2)=x^2-6x+16[/tex]
So the function g(x) is:
[tex]g(x)=x^2-6x+16[/tex]
Use the following formula to find the x-coordinate of the vertex of g(x):
[tex]x=\frac{-b}{2a}[/tex]
In this case:
[tex]a=1\\b=-6[/tex]
Then:
[tex]x=-\frac{-(-6)}{2(1)}=3[/tex]
Substitute this value into the function g(x) in order to find the y-coordinate of the vertex. Since [tex]g(x)=y[/tex], you get:
[tex]y=3^2-6(3)+16=7[/tex]
Therefore, the vertex of g(x) is:

-2.5 + (-3.5)
Which number line shows the sum?
Final answer:
The sum of -2.5 and (-3.5) is -6.0, which is found by adding the absolute values of the numbers and giving the result a negative sign. The correct number line representation for this sum would show a leftward movement from -2.5 by 3.5 units to end at -6.0.
Explanation:
When calculating the sum of -2.5 and (-3.5), we follow the rule that when two negative numbers are added, the answer has a negative sign. Both numbers in the sum are negative, therefore, we add their absolute values and then give the result a negative sign. The calculation is as follows:
-2.5 + (-3.5) = -(2.5 + 3.5) = -6.0
The number line that shows this sum would start at -2.5 and move left (which indicates adding a negative number) 3.5 units, landing on -6.0.

Max scored 6 marks more than what he did in the previous
examination in which he scored 30. Maria scored 30 marks more
than she did in the previous examination in which she scored 60.
Who showed less improvement?
♡
Answer:
max showed less improvement!
Step-by-step explanation:
Max percentage improvement in the first exam = (6/30 × 100) %
= (600/30) %
= 20 %
Maria percentage improvement in the first exam = (30/60 × 100) %
= (3000/60) %
= 50 %
Hence, 20 % < 50 %
Final answer:
Max improved by 6 marks from his previous score, while Maria improved by 30 marks. Therefore, Max showed less improvement than Maria.
Explanation:
Max scored 6 marks higher than his previous score of 30, making his new score 36. Maria scored 30 marks more than her previous score of 60, taking her new score to 90. To determine who showed less improvement, we compare the amount of increase in their scores.
Max's improvement: 30 + 6 = 36
Maria's improvement: 60 + 30 = 90
Max improved by 6 marks, and Maria improved by 30 marks. Therefore, Max showed less improvement.
When comparing improvement, it's useful to look at the actual increase in marks gained, not necessarily the percentage improvement unless specifically asked. Here, the simple comparison of the additional marks scored determines who improved less. Though both students improved their scores, the difference in their points increased is a clear indicator of whose improvement was less significant.

The horizontal line through (3,7) in point-slope form
In mathematics, a horizontal line has a slope of 0, and its equation is always 'y = b', where 'b' is the y-coordinate of any point on the line. In this situation, since our line passes through the point (3,7), the equation of the horizontal line is 'y = 7'.
Explanation:In the context of mathematics, a horizontal line is a line whose equation is in the form y = b where 'b' represents the y-intercept, or the y-coordinate of a certain point on the line. In this question, you are asked to find the point-slope form of a horizontal line passing through the point (3,7).
However, for a horizontal line, the point-slope form y = mx + b becomes y = b because m, the slope of a horizontal line, is 0. And the y-coordinate of any point on a horizontal line is the same.
So, since the line is passing through the point (3,7), the y-coordinate 7 is constant throughout the horizontal line. Therefore, the equation of the horizontal line through (3,7) would be y = 7.

Determine the domain
Answer:
see explanation
Step-by-step explanation:
Given the range of f(x), find the domain by equating f(x) to each of the values in the range, that is
5x + 4 = 5 ( subtract 4 from both sides )
5x = 1 ( divide both sides by 5 )
x = [tex]\frac{1}{5}[/tex]
5x + 4 = 6 ( subtract 4 from both sides )
5x = 2 ( divide both sides by 5 )
x = [tex]\frac{2}{5}[/tex]
5x + 4 = 7 ( subtract 4 from both sides )
5x = 3 ( divide both sides by 5 )
x = [tex]\frac{3}{5}[/tex]
5x + 4 = 8 ( subtract 4 from both sides )
5x = 4 ( divide both sides by 5 )
x = [tex]\frac{4}{5}[/tex]

A book has 500 pages numbered 1,2,3 and so on. How many times does the digit 1 appear in the page numbers?
Answer:
[tex]200[/tex]
Step-by-step explanation:
This book has 500 pages in total.
We should split up the place values.
1 - 9
One only appears once.
1
10 - 19
One appears 11 times.
1 + 11
20 - 99
One only appears 8 times.
1 + 11 + 8
Add:
1 + 11 + 8
=> 20
Since the same is for 200-299, and so on. Let us add twenty four times.
20 * 4
=> 80
Looking back to 100-199, there are 120 ones.
Add:
120 + 80
=> 200
The total number of times that the digit 1 appears in the page numbers is: 200
How to find the number of pages of the book?In the first 99 pages there are:
1 one in the first 9 pages,
11 ones in pages 10-19 (one each for 10 and 12-19, and two for 11)
8 ones in pages 20-99 (21, 31, 41, 51, 61, 71, 81, and 91)
So we have 20 ones in the first 99 pages.
Likewise we have 20 ones in pages 200-299, 20 ones in pages 300-399, and 20 ones in pages 400-499. There are 0 ones on page 500.
For pages 100-199, there are 100 ones for the hundreds digits in addition to the 20 ones found in the tens and ones digits.
So we have a total of 20 + 120 + 20 + 20 + 20 = 200 ones on the page numbers.

four 3 megawatt wind turbines can supply enough electricity to power 3000 homes. How many turbines would be required to power 55,000 homes?
Answer:
The number of turbines is 74
Step-by-step explanation:
* Lets explain how to solve the problem
- Four 3 megawatt wind turbines can supply enough electricity
to power 3000 homes
∴ The number of turbines is 4
∵ Each turbine give 3 megawatt
∴ The four turbines give ⇒ 4 × 3 = 12 megawatt
- This quantity give enough electricity to power 3000 homes
∴ The number of homes for the 12 megawatt is 3000
- We need to find how many turbines can cover enough electricity
to power 55,000 homes, so we must to know the quantity of
electricity that be enough to power 55,000 homes
* Lets use the cross multiplication to solve the problem
∵ megawatt : number of homes
12 : 3,000
? : 55,000
- By using cross multiplication
∴ [tex]?=\frac{(55,000)(12)}{3,000}=\frac{660,000}{3000}=220[/tex]
∴ The enough electricity to power 3000 homes = 220 megawatt
∵ Each turbine gives 3 megawatt
- Find the number of turbines divides the total megawatt by the the
megawatt of one turbine
∴ The number of turbines = 220 ÷ 3 = 73.3
- If we take 73 only the electricity will not be enough to cover all
homes, so we must to take 74 turbines
∴ The number of turbines is 74
To power 55,000 homes, approximately 74 wind turbines are required. Each turbine can power 750 homes, derived from the initial data where 4 turbines power 3,000 homes.
To determine how many 3 megawatt wind turbines are required to power 55,000 homes, we can use a simple proportion based on the given data.
We know that:
4 turbines can power 3,000 homes.Therefore, 1 turbine can power 750 homes (since 3000 / 4 = 750).Now, we need to find out how many turbines are needed to power 55,000 homes:
Number of turbines needed = 55,000 homes / 750 homes per turbine.This calculation gives us approximately 73.33 turbines.Since we can't have a fraction of a turbine in practical terms, we would need 74 turbines to ensure all 55,000 homes are powered.

Answer:
The strategy to evaluate these expressions is called PEMDAS.
Step-by-step explanation:
Problem #1[tex]15-[(3^2+6)\div5][/tex]
We're going to be following the rule of PEMDAS:
ParenthesesExponentsMultiplicationDivisionAdditionSubtractionKeep in mind that multiplication/division and addition/subtraction are done from left to right.
In the first expression (written above), we'll first evaluate everything inside the brackets first (brackets are used when there are parentheses inside of it - but they serve the same function). There are parentheses in these brackets, so that will be the absolute first step in evaluating.
Solve for [tex]3^2+6[/tex] then rewrite the expression.
[tex]15-[(15)\div5][/tex]Now finish evaluating inside the parentheses by dividing 15 by 5.
[tex]15-[3][/tex]The last step to evaluate the expression is to subtract 3 from 15.
12Problem #2[tex]4\times[50-3(1+3)^2][/tex]
Evaluate everything inside the the brackets. Start with the parentheses since that is first according to PEMDAS. Add 1 and 3 together then rewrite the expression.
[tex]4\times[50-3(4)^2][/tex]Exponents are solved next after parentheses in PEMDAS, so evaluate the exponent.
[tex]4\times[50-3(16)][/tex]Multiplication is done before subtraction, so multiply 3 and 16 together.
[tex]4\times[50-(48)][/tex]Finish evaluating inside the brackets by subtracting 48 from 50.
[tex]4\times[2][/tex]The last step in evaluating the second expression is to multiply 4 and 2 together, which gives us 8.
8Bobby wants to invest $100. His brother invested $2,000 for one year and earned $60 in simple interest.
If Bobby invests his money for one year at the same interest rate as his brother, how much interest will he earn?
O A. $3
OB. $6
OC. $12
OD. $30
OE. $33
Answer:
$3
Step-by-step explanation:
By investing $2,000 Bobby will earn $60 interest
∴By investing $1 Bobby will earn =$(60/2000) interest
so,
By investing $100,
He will earn =$ {(60/2000 ) .100}
=$3
If Bobby invests his money for one year at the same interest rate as his brother, then he will earn $3 amount.
Thus, option A $3 is correct.
Given that:Amount Bobby wants to invest = $100Time for which Bobby wants to invest = 1 year.Amount his brother invested = $2000Time interval for which his brother invested money = 1 year.Simple interest earn by his brother = $60To find:Interest that Bobby will earn at same interest rate as his brother after 1 year of investment of $100.
Calculations:If someone invests P amount for T years with simple interest rate R% per year, then the simple interest that that person will earn is given by:
[tex]SI = \dfrac{P \times R \times T}{100}[/tex]
Putting values of P, R and T of Bobby's brother's investment, we have:
[tex]60 = \dfrac{2000 \times 1 \times R}{100}\\\\6000 = 2000R\\\\R = \dfrac{6000}{2000} = 3\%[/tex]
At that rate, the SI for Bobby's $100 investment for 1 year is:
[tex]SI = \dfrac{100 \times 3 \times 1}{100} = \$3[/tex]
Thus, Bobby will get $3 as interest.

You have already 5 miles of an 18 -miles trail. If you walk the rest of the rest of the trail at a pace of 1 mile in 17 minutes, How many wile it take you to finish the trail?
To finish the remainder of the 18-mile trail, it will take 3 hours and 41 minutes at a pace of 1 mile in 17 minutes.
Explanation:To find out how many miles it will take to finish the trail, subtract the distance already covered from the total length of the trail. In this case, subtract 5 miles from 18 miles to get 13 miles remaining. Next, divide the remaining distance by the pace at which you walk, which is 1 mile in 17 minutes. So, if it takes 17 minutes to walk 1 mile, it will take 17 times 13 minutes to finish the rest of the trail. Finally, calculate the total time in minutes by multiplying: 17 times 13 equals 221 minutes, or 3 hours and 41 minutes to finish the trail.

(1) Write down the scale factor, and use this to find the percentage increase in the weight each week.
(2) Use the law of logs to find the age at which the puppy will weigh 4000 grams
Answer:
See explanation
Step-by-step explanation:
A dog owner observes that from birth to age 14 weeks, the puppy’s weight can be modelled by the equation
[tex]w = 365\cdot (1.23)^t \ (0\le t \le 14)[/tex]
In this equation,
number 365 represents the initial weight of puppy;number 1.23 can be rewritten as 1+0.23, where 0.23 (or 23%) is the rate of weight increase.When w=4,000, then
[tex]4,000=365\cdot (1.23)^t\\ \\(1.23)^t =\dfrac{4,000}{365}=\dfrac{800}{73}\\ \\t=\log_{1.23}\dfrac{800}{73}\approx 11.5651[/tex]
This means that puppy will weight 4,000 grams nearly at the middle between 11th week and 12th week.

Answer:
Area = 28800 cm².
Step-by-step explanation:
Given : If the perimeter of International Space Station Base, which is rectangular in shape, is 720 cm and its length is 120cm,
To find : find the area of the International Space Station Base.
Solution : We have given
Perimeter = 720 cm .
Length = 120 cm .
Perimeter = 2 ( length + width ) .
Plugging the values
720 = 2 ( 120 + width )
On dividing both sides by 2
360 = 120 + width .
On subtracting both sides by 120.
240 cm = width.
Area = length * width .
Area = 120 * 240 .
Area = 28800 cm².
Therefore, Area = 28800 cm².
