Every five years in march, the population of a certain town is recorded. In 1995,the town had a population of 4,500 people. From 1995 to 200, the population increased by 15%. From 2000 to 2005,the population decrease d by 4%. What was the town's population in 2005?

Answers

Answer 1
Hello!

So, the town had a population on 4,500 people in 1995. Then from 1995 to 2000, the population increased by 15%.

Convert 15% to a decimal by dividing it by 100. Then, the population in 1995 by this decimal.

15% ÷ 100 = 0.15

4,500 × 0.15 = 675

Now, add this to the population in 1995.

4,500 + 675 = 5,175

This means that the town had a population of 5,175 people in 2000.

To calculate the town's population in 2005, repeat the same steps we took to find the population in 2000, except this time we will subtract instead of add since the population DECREASED.


4% ÷ 100 = 0.4

5,175 × 0.4 = 207

5,175 - 207 = 4,968

FINAL ANSWER:

The town had a population of 4,968 in 2005.

EXPLANATION

The given system of equations is

[tex]y = - 3x + 7...(1)[/tex]

and

[tex]x = - 2y - 16...(2)[/tex]

We substitute equation (1) into equation (2) to get;

[tex]x = - 2( - 3x + 7) - 16[/tex]

[tex]x = 6x - 14- 16[/tex]

We group similar terms

[tex]x - 6x = - 14 - 16[/tex]

[tex] - 5x = - 30[/tex]

Divide both sides by -5.

[tex]x =6[/tex]

Put x=6 into equation (1).

[tex]y = - 3(6) + 7[/tex]

[tex]y = - 18 + 7[/tex]

[tex]y = - 11[/tex]

Answer:

x = 6 and y = -11  

Step-by-step explanation:

Given : System of linear equation

y=−3x+7

x=−2y−16

We have to solve the system of equations using the substitution method.

In substitution method, we substitute the value of one variable in term of other and solve for it.

Consider the given system of linear equation

y = −3x + 7  ...(1)

x = −2y − 16 .....(2)

Substitute, (2) in (1), we get,

y = -3(-2y - 16) + 7

Simplify , we get,

y = 6y + 48 + 7

6y - y = - 55

5y = -55

y = -11

Substitute y = -11 in (2), we get,

x = −2(-11) − 16 = 22 - 16 =  6

thus, x = 6

Thus , x = 6 and y = -11

[tex]4x + 8 \geqslant 32[/tex]
[tex]4x \geqslant 24[/tex]
[tex]x \geqslant 6[/tex]
Sally was paid at least 6 dollars /hour.
Final answer:

A real-world situation for the inequality 4x + 8 ≥ 32 could involve calculating the minimum hours required at a part-time job to earn $32. Subtracting 8 and dividing by 4, we find that at least 6 hours of work are needed.

Explanation:

A real-world example that could be solved by using the inequality 4x + 8 ≥ 32 might involve a situation where you need to determine how many hours you must work at a part-time job to earn at least a certain amount of money. Suppose you earn $4 per hour and you have already earned $8. You want to know the minimum number of hours you must work to have at least $32 in total.

To solve the inequality 4x + 8 ≥ 32, you would first subtract 8 from both sides, which gives you 4x ≥ 24. Then, you would divide both sides by 4 to find the number of hours (x) you need to work. Therefore, x ≥ 6. This means you must work at least 6 hours to earn $32 or more.

You're solving this equation for the variable 'v', so the main goal is to isolate it on one side of the equation.

     7 + 11v = 9v - 9            Subtract 7 from both sides
7 - 7 + 11v = 9v - 9 - 7       Simplify
           11v = 9v - 16           Subtract 9v from both sides
    11v - 9v = 9v - 9v - 16   Simplify
            2v = -16                 Divide both sides by 2

One number is 33 more than another number. The quotient of the larger number and smaller number is 5 and the remainder is 1. Find the numbers.

Answers

The two numbers are 41 and 8. You can set up the problem as two equations. First, x = 33 + y for "one number (x) is (=) 33 more (33 +) than another number (y)." You can set up the other equation as (x-1)/5y or (x-1) = 5y. You can substitute 33 + y for every x in the second equation and solve for y. You would get y = 8, then you can use the y value in the first equation to solve for x to get x = 41. 

Final answer:

The two numbers in question are 8 and 41.

Explanation:

Step-by-Step Solution to Find the Two Numbers

Let the smaller number be x. Thus, the larger number would be x + 33. According to the problem, the larger number divided by the smaller number gives a quotient of 5 and a remainder of 1. We can represent this information using the following equation:

(x + 33) = 5x + 1

This equation states that when the larger number is divided by the smaller number, we obtain a quotient of 5 and a remainder of 1.

Now, let's solve the equation for x:

Subtract 5x from both sides of the equation: (x + 33) - 5x = 1Simplify the equation: -4x + 33 = 1Subtract 33 from both sides: -4x = -32Divide both sides by -4: x = 8

Since we have found the smaller number to be 8, the larger number is:

8 + 33 = 41

Therefore, the two numbers are 8 and 41.

The modulus operator would confirm our solution since 41 % 8 does indeed yield a remainder of 1, as stated in the problem.

if the circumference of a circle measures 3π cm, what is the area of the circle in terms of π?

Answers

the circumference equation is 2pi r and the circumference for this problem is 3pi so that would mean that the radius is 1.5

with that info, we can find out the area of the circle which is pi r squared.
1.5*1.5=2.25
 
AREA=2.25pi

The area of the given circle, in terms of pi, is:

A = (9/4)pi cm^2

How to find the area of the circle?

We know that for a circle of radius R, the circumference is:

C = 2*pi*R

And the area is:

A = pi*R^2

In this case, we know that:

C = 3pi cm = 2pi*R

Then we must have:

3cm = 2R

(3/2)cm = R

Now we can replace this on the area equation:

A = pi*((3/2)cm)^2 = pi*(9/4) cm^2

Alice has 1/5 as many miniature cars as Sylvester has Sylvester has 35 miniature cars how many miniature cars does alic have?

Answers

The answer is 7. Since Alice has 1/5 as many cars as Sylvester. You multiply 1/5 by how many cars Sylvester has. Sylvester has 35 cars, so you would do 35 times 1/5 or 35 divided by 5 (multiply by 1/5 and divided by 5 are the same thing) and you would get your answer of 7.

Final answer:

Alice has 1/5 as many miniature cars as Sylvester, who owns 35. By multiplying 35 cars by 1/5, we find that Alice has 7 miniature cars.

Explanation:

The student's question is about finding the number of miniature cars Alice has if she has 1/5 as many as Sylvester, who has 35 miniature cars. To solve this, we use the following mathematical operation:

Alice's miniature cars = 1/5 of Sylvester's miniature cars

Sylvester's miniature cars = 35 cars

To find out how many miniature cars Alice has, multiply the number of Sylvester's miniature cars by 1/5:

35 cars x 1/5 = 7 cars

Therefore, Alice has 7 miniature cars.

a sheep breeding farm counted a total of 40 sheep on their grounds after one year the number of sheep doubled then in the next year the number of sheep doubled again if this trend continues which of the following options represents the number of sheep on the farm by then end of each year

Answers

Answer:
graph (b)

Explanation:
The farm started with 40 sheep and the number doubled each year.
So, the equation modeling this situation would be:
N(x) = 40*(2)^2
By getting the equation, we can notice that we already excluded the third and fourth choices as they have the wrong equations.

Now, we will need to select the right graph which is either graph a or graph b.
To do this, we will get the value of N(x) for different values of x as follows:
At x = 0: N(0) = 40*(2)^0 = 40
At x = 1: N(1) = 40*(2)^1 = 80
At x = 1: N(2) = 40*(2)^2 = 160

Now, taking a look at graph a, we will find that:
N(1) = 120
N(2) = 360
These numbers are not the same as the numbers we calculated, therefore, this graph is wrong

Taking a look at graph b, we will find that:
N(1) = 80
N(2) = 160
These numbers are exactly the same as the ones calculated, therefore, this graph is the correct one.

Is the quotient of 5 and 1 / 2 greater than or less than 5? Explain your answer.

Answers

the qoutient of 5 and 1/2 is 2.5 so it is less than

The quotient of 5 divided by 1/2 is greater than 5 because dividing by a number less than 1 results in a larger number. In this case, it is equivalent to multiplying 5 by 2, yielding 10.

To determine if the quotient of 5 and 1/2 is greater than or less than 5, we consider the operation of division. Dividing by a number less than 1 will result in a larger number, while dividing by a number greater than 1 will result in a smaller number. The number 1/2 is less than 1, so when 5 is divided by 1/2, the quotient is greater than 5. It is equivalent to multiplying 5 by 2 (since dividing by a fraction is the same as multiplying by its reciprocal), which is 10. Therefore, 5 divided by 1/2 equals 10, which is greater than 5.

The total employment compensation of the employee is b. $70,970.

What are Arithmetic operations?

Arithmetic operations are the basic part of mathematics which combines the basic operations like addition, subtraction, multiplication and division.

Given that,

Annual salary of the employee = $51,300

Health insurance per year = $2,830

Paid time off per year = $4,600

Monthly expense for personal vehicle = $600

Yearly expense = 12 × $600 = $7200

Reimbursement for the vehicle = $0.54 per work mile

Reimbursement for vehicle for 36,000 miles for work for the year = $0.54 × 36,000 miles = $19,440

Total employment compensation = ($51,300 + $2,830 + $4,600 + $19,440) - $7200

= $70,970

Hence the employment compensation is $70,970.

Final answer:

Residual plots can indicate the appropriateness of a linear model by examining patterns and deviations of the residuals.

Explanation:

A residual plot is a graph that shows the difference between the observed and predicted values in a linear regression model. It helps to assess the appropriateness of the linear model by examining the patterns and deviations of the residuals. In the first graph, there seems to be a systematic pattern and non-randomness in the residuals, indicating that the linear model may not be appropriate. However, in the second graph, the residuals are randomly scattered around zero with no evident pattern, suggesting that the linear model is more appropriate.

The cotton gin is credited to the brilliant and creative American inventor Eli Whitney. Because Whitney's invention made cotton harvesting easier, it allowed farmers in the South to increase production. The cotton gin simplified the process of removing the cotton from the seeds, a process formerly done by hand.As a result, Southern plantations increased their production of cotton from 750,000 bales in 1830 to 2.85 million bales just 20 years later. Because of the increase in production, the farmers in South became even more dependent on cotton for revenue. This new reliance on cotton increased the need for slavery. More slaves were needed to farm the ever expanding cotton plantations. If Whitney had known the effects his invention would have on slavery, he never would have created it.Read the passage.
