Answer 1

1) The maximum amount you should spend on rent is $840.

2) The maximum amount you should spend on rent is $570.

3) Your monthly income must be at least $2,733.33 to afford this apartment.

4) Your monthly income must be at least $3,000 to afford this apartment.

5) You need $1,980 to start renting the apartment.

1) With a monthly income of $2,800, the maximum amount you should spend on rent can be calculated using the 30% rule.
$2,800 x 0.30 = $840
So, the maximum amount you should spend on rent is $840.

2) With a monthly income of $1,900, the maximum amount you should spend on rent can be calculated using the 30% rule.
$1,900 x 0.30 = $570
So, the maximum amount you should spend on rent is $570.

3) To afford an apartment that rents for $820, your monthly income should be:
$820 ÷ 0.30 = $2,733.33
So, your monthly income must be at least $2,733.33 to afford this apartment.

4) To afford an apartment that rents for $900, your monthly income should be:
$900 ÷ 0.30 = $3,000
So, your monthly income must be at least $3,000 to afford this apartment.

5) To start renting an apartment that costs $665/month, you need the first and last month's rent, and a $650 security deposit.
First and last month's rent: $665 x 2 = $1,330
Total amount needed: $1,330 + $650 = $1,980
So, you need $1,980 to start renting the apartment.

Due to the annual rate of inflation, a gallon of milk that costs $3. 25 today would have cost $1. 75 if it was bought 20 years ago.

Answers

The annual rate of inflation between the two time periods is approximately 3.05%.

To calculate the annual rate of inflation, we can use the formula:

Annual Inflation Rate = ((Current Price - Past Price) / Past Price) * 100 / Number of Years

Plugging in the values, we have:

((3.25 - 1.75) / 1.75) * 100 / 20 ≈ 0.153 * 100 / 20 ≈ 3.05%

Therefore, the annual rate of inflation between the two time periods is approximately 3.05%.

Inflation refers to the general increase in prices over time, which leads to a decrease in the purchasing power of money. In this case, the cost of a gallon of milk has increased from $1.75 to $3.25 over 20 years. By calculating the annual rate of inflation, we find that prices have been rising at an average rate of 3.05% per year during this period.

This means that the cost of goods and services, including milk, has increased by an average of 3.05% each year due to inflation. It highlights the importance of considering inflation when comparing prices and understanding the impact it has on the value of money over time.

In conclusion, based on the given information, the annual rate of inflation between the two time periods is approximately 3.05%, indicating the increase in the cost of a gallon of milk over 20 years.

You babysat your neighbor's children, and they paid you $45 for 6 hours.

What is the rate?

What is the unit rate?

Write a function rule to represent this situation.

Answers

Answer:

The rate is $7.50 per hour.

The unit rate is $7.50 per hour.

This function rule represents the relationship between the number of hours worked (x) and the amount earned (y) at a rate of $7.50 per hour.

Step-by-step explanation:

To find the rate, divide the total amount earned by the number of hours worked. In this case, you earned $45 for 6 hours.

Rate = Total amount earned / Number of hours worked

Rate = $45 / 6 hours

Rate = $7.50 per hour

The rate is $7.50 per hour.

The unit rate refers to the rate per unit of one. In this case, it would be the rate per hour.

Unit Rate = Rate / Number of units

Unit Rate = $7.50 / 1 hour

Unit Rate = $7.50 per hour

The unit rate is $7.50 per hour.

To write a function rule to represent this situation, let's use "x" to represent the number of hours worked and "y" to represent the amount earned:

y = Rate * x

Since the rate is $7.50 per hour, the function rule can be written as:

y = 7.50x

Answers

The solution for the differential equation is y = (23/48) x + 4.

How to determined the ordinary differential equation?

(A) Re-writing the differential equation in terms of differentials, we get:

dy = (23/48) dx

Here, dy and dx represent infinitesimal changes in the variables y and x, respectively.

(B) Integrating both sides of the equation with respect to their respective variables, we get:

∫dy = ∫(23/48)dx

On the left-hand side, the integral of dy is simply y (plus a constant of integration), while on the right-hand side, we can pull the constant factor (23/48) outside the integral:

y + C1 = (23/48) ∫dx

Integrating the right-hand side with respect to x, we get:

y + C1 = (23/48) x + C2

where C1 and C2 are constants of integration.

(C) To solve for y, we can isolate it on one side of the equation by subtracting C1 from both sides:

y = (23/48) x + (C2 - C1)

Next, we can use the initial condition y(0) = 4 to solve for the constant C2 - C1:

y(0) = (23/48) (0) + (C2 - C1) = C2 - C1

Since y(0) = 4, we have:

4 = C2 - C1

Therefore, C2 - C1 = 4, and we can substitute this back into the expression for y to get the final solution:

y = (23/48) x + 4

So the solution for the differential equation with initial condition y(0) = 4 is y = (23/48) x + 4.

Answers

The value of m by the given data is m=2

We are given that;

Number of elephants= 125000gram

The mass of african elephant= 3 x 10

Now,

To find the values of b and c, we need to write the given masses in scientific notation, which means that the coefficient must be between 1 and 10. For example, 6 x 10 grams is not in scientific notation, because 6 is not between 1 and 10. To fix this, we need to move the decimal point one place to the left and increase the exponent by one. We get:

6x106 grams=6.0x106 grams=6.0x106−1×101 grams=6.0x105×101 grams=6.0x105+1 grams=6.0x107 grams

Similarly, for the silverback gorilla, we get:

2x105 grams=2.0x105 grams=2.0x105−1×101 grams=2.0x104×101 grams=2.0x104+1 grams=2.0x105 grams

Therefore, the values of b and c are b=7,c=5

To find the value of m, we need to divide the mass of the African elephant by the mass of the silverback gorilla and write the result in scientific notation. We get:

Mass of silverback gorillaMass of African elephant​=2.0x105 grams6.0x107 grams​=2.06.0​×105107​=3.0×107−5=3.0×102

The mass of a tumor grows at a rate proportional to its size. The first measurement of its size was 4. 0 grams. Four months later its mass was 6. 76 grams. How large was the tumor six months before the first measurement? If the instrument can detect tumors of mass 1 gram or greater, would the tumor have been detected at that time?

Answers

The tumor was approximately 1.47 grams six months before the first measurement. It would not have been detected by the instrument at that time.

Let M(t) be the mass of the tumor at time t (in months) since the first measurement. Since the rate of growth is proportional to the size of the tumor, we have the differential equation dM/dt = kM, where k is the proportionality constant. The general solution to this differential equation is M(t) = Me^(kt), where M is the initial mass of the tumor.

Using the given data, we have M(0) = 4.0 and M(4) = 6.76. Substituting these values into the equation M(t) = Me^(kt), we get the system of equations M = 4.0 and 6.76 = Me^(4k). Solving for M and k, we get M = 4.0 and k = ln(6.76/4.0)/4 ≈ 0.153. Thus, the equation for the mass of the tumor is M(t) = 4.0e^(0.153t).

To find the mass of the tumor six months before the first measurement (i.e., when t = -6), we plug in t = -6 into the equation M(t) = 4.0e^(0.153t) to get M(-6) ≈ 1.47 grams.

Finally, we check whether the tumor would have been detected at that time. Since the mass of the tumor was less than 1 gram at that time, the instrument would not have detected it.

For the function f(x,y) = x^2 e^{3xy}, find fx, and fy.

Answers

For function f(x,y) = x² e^{3xy} ,  fx = 2xe^{3xy} + 3x²y e^{3xy}, fy = 3x² e^{3xy}

The given function is f(x,y) = x² e^{3xy}.

To find the partial derivatives of f(x,y) with respect to x and y,

we differentiate the function with respect to each variable while treating the other variable as a constant.

To find fx, we differentiate the function f(x,y) with respect to x while treating y as a constant.

The derivative of x² is 2x, and the derivative of e^{3xy} is e^{3xy} times the derivative of 3xy with respect to x, which is 3y.

Therefore, we get:

fx = (d/dx)(x² e^{3xy}) = 2xe^{3xy} + 3x²y e^{3xy}

To find fy,

we differentiate the function f(x,y) with respect to y while treating x as a constant.

The derivative of e^{3xy} with respect to y is e^{3xy} times the derivative of 3xy with respect to y, which is 3x². Therefore, we get:

fy = (d/dy)(x² e^{3xy}) = 3x² e^{3xy}

Hence, the partial derivatives of f(x,y) are fx = 2xe^{3xy} + 3x^2y e^{3xy} and fy = 3x² e^{3xy}.

Find the mass and center of mass of the lamina that occupies the region D and has the given density function p. D is bounded by y = e, y = 0, x = 0, and x = 1; p(x, y) = 31y

Answers

The mass of the lamina that occupies the region D is 31/2 units and the center of mass is located at (1/2, 2/e).

We can find the mass of the lamina by integrating the density function over the region D:

m = ∫∫D p(x,y) dA

where dA is the area element in polar coordinates, which is equal to r dr dθ. The region D can be described as 0 ≤ x ≤ 1 and 0 ≤ y ≤ e, so the integral becomes:

m = ∫0^1 ∫0^e 31y dy dx

Solving the integral, we get:

m = 31/2

To find the center of mass, we need to find the x-coordinate and y-coordinate separately:

x = (1/m) ∫∫D x p(x,y) dA

y = (1/m) ∫∫D y p(x,y) dA

For the x-coordinate, we have:

x = (1/m) ∫0^1 ∫0^e x(31y) dy dx

Simplifying, we get:

x = (1/m) ∫0^1 31/2 x dx

x = 1/2

For the y-coordinate, we have:

y = (1/m) ∫0^1 ∫0^e y(31y) dy dx

Simplifying, we get:

y = (1/m) ∫0^1 31/3 e^3 dx

y = (2/e)

Answers

The probability that the mean weight of the sample of horses would differ from the population mean by greater than 18lbs if 41 horses are sampled at random from the large stable is approximately 0.131 or 13.1%.

Suppose the horses in a large stable have a mean weight of 807lbs and a variance of 5776. We want to find the probability that the mean weight of a sample of 41 horses would differ from the population mean by greater than 18lbs.

Step 1: Calculate the standard deviation of the population.
Standard deviation (σ) = √variance = √5776 = 76lbs.

Step 2: Calculate the standard error of the mean.
Standard error (SE) = σ / √n = 76 / √41 ≈ 11.88lbs, where n is the sample size (41 horses).

Step 3: Calculate the z-score for the difference of 18lbs.
z = (difference - 0) / SE = (18 - 0) / 11.88 ≈ 1.51

Step 4: Find the probability corresponding to the z-score.
Using a z-table, we find that the probability corresponding to a z-score of 1.51 is approximately 0.9345.

Step 5: Calculate the probability of the mean weight differing by more than 18lbs.
Since we are looking for the probability of the mean weight differing by more than 18lbs (in either direction), we need to consider both tails of the distribution.
P(z > 1.51) = 1 - 0.9345 = 0.0655
P(z < -1.51) = 0.0655 (since the distribution is symmetric)

Total probability = P(z > 1.51) + P(z < -1.51) = 0.0655 + 0.0655 = 0.1310

So, the probability that the mean weight of the sample of horses would differ from the population mean by greater than 18lbs if 41 horses are sampled at random from the large stable is approximately 0.131 or 13.1%.

A group of students collected old newspapers for a recycling project. The data shows the mass, in kilograms, of old newspapers collected by each student. What percent of students collected between 49 kilograms and 98 kilograms of newspapers

Answers

37.5% of the students collected between 49 and 98 kilograms of newspapers for the recycling project. Percentage method can be used here.

To answer this question, we need to determine the number of students who collected between 49 and 98 kilograms of newspapers and then calculate what percentage of the total number of students that represents.

First, we need to gather the data and sort it into categories. We can create a frequency table with intervals of 10 kilograms:
Mass Range | Number of Students
   0-9 kg               3
   10-19 kg            5
  20-29 kg           7
  30-39 kg           4
  40-49 kg           6
  50-59 kg           8
  60-69 kg           5
  70-79 kg           2
  80-89 kg           1
  90-99 kg           2


To find the number of students who collected between 49 and 98 kilograms of newspapers, we need to add up the frequencies for the 50-59, 60-69, and 70-79 kg categories. That gives us a total of 15 students.
To calculate the percentage of students who collected between 49 and 98 kilograms of newspapers, we need to divide the number of students in that range by the total number of students and then multiply by 100. In this case, we have 15 students in the range and a total of 40 students overall, so:

Determine whether the triangles ar similar. It so, write a similarity statement and name the postulate or theorem you used. If not, explain.

Answers

Answer:

Option B.

Step-by-step explanation:

Angle SOB and Angle VOK are vertical angles, and thus congruent because all vertical angles are congruent.

Lines SB and KV are parallel, cut by the transversal SV, and Angle S and Angle V are Alternate Interior Angles.  So, Angle S and Angle V are congruent by Alternate Interior Angle congruence.

Therefore, Triangle SOB and Triangle VOK are similar by Angle Angle similarity postulate.

WHAT IS P(x) =

Answers

The simplified expression for p(z), the profit the company earns, in dollars is: p(z) = -3z² + 18z

What is function?

The set X is known as the domain of the function, and the set Y is known as the codomain of the function. A function from a set X to a set Y assigns each element of X to exactly one element of Y. Originally, functions were an idealization of how one variable depends on another.

According to question:

First, let's substitute the expressions for r(z) and c(z) in the expression for p(z):

p(z) = r(z) - c(z)

p(z) = 60z - (3z² + 42z)

p(z) = 60z - 3z² - 42z

p(z) = -3z² + 18z

Therefore, the simplified expression for p(z), the profit the company earns, in dollars is:

p(z) = -3z² + 18z

The school district surveyed 500 families to see if they were satisfied or not satisfied with the new district website. There were 480 families who responded that they were satisfied. The margin of error was 0.027. If the school district has 140,000 families, what is the maximum number of families who are satisfied with the new district website?

Answers

If the school district surveyed 500 families to see if they were satisfied or not satisfied with the new district website. the maximum number of families who are satisfied with the new district website is approximately 130,771.

How to find the maximum number?

First, we need to calculate the confidence level, which is 1 minus the margin of error:

Confidence level = 1 - margin of error

Confidence level = 1 - 0.027

Confidence level = 0.973

Next, we can use the proportion of satisfied families in the sample to estimate the proportion in the population:

Proportion satisfied in population = Proportion satisfied in sample

Proportion satisfied in population = 480/500

Proportion satisfied in population = 0.96

Now we can use this proportion and the confidence level to calculate the maximum number of satisfied families in the population:

Maximum number of satisfied families = Proportion satisfied in population x Total number of families x Confidence level

Maximum number of satisfied families = 0.96 x 140,000 x 0.973

Maximum number of satisfied families ≈ 130,771

Therefore, the maximum number of families who are satisfied with the new district website is approximately 130,771.

Jill is starting her own business called Fuzzy Socks Box, where she'll knit and sell gift boxes of fuzzy socks online. She conducted a survey to predict how the price she charges per gift box will affect how many gift boxes she'll sell. She concluded that if she charges x dollars per gift box, she'll sell – 10x+350 gift boxes in her first month. It will cost Jill $2 to create each gift box. So, she will earn x–2 dollars in profit per gift box. What is the lowest price Jill can charge per gift box to earn $2,000 in profit in her first month?

Answers

The lowest price she can charge per gift box to earn $2,000 in profit in her first month is approximately $3.2.

Jill is starting her own business called Fuzzy Socks Box, where she'll knit and sell gift boxes of fuzzy socks online.

Jill's profit per gift box is x - 2 dollars. To earn $2,000 in profit in her first month, she needs to sell

2000 / (x - 2) gift boxes.

According to her survey, the number of gift boxes she'll sell is

-10x + 350

Setting these two expressions equal to each other, we can find the lowest price Jill can charge per gift box to earn $2,000 in profit

-10x + 350 = 2000 / (x - 2)

Multiplying both sides by (x - 2), we get

-10[tex]x^{2}[/tex] + 12x - 470 = 0

Solving this quadratic equation, we find that

x = (6 +[tex]\sqrt{196[/tex] )/5 ≈ 3.2

or

x = (6 -[tex]\sqrt{196[/tex] )/5 ≈ 0.7

Since Jill cannot charge a negative price for her gift boxes, the lowest price she can charge per gift box to earn $2,000 in profit in her first month is approximately $3.2.

which is a feature of function g if g(x) = -4 log(x – 8)?

a. the domain is x< 8.

b. the range is y > -8.

c. the value of the function decreases as x approaches positive infinity.

d. the value of the function increases as x approaches positive infinity.


wrong answers will be reported!!

Answers

The correct answer is option c i.e. the value of the function decreases as x approaches positive infinity.

The function g(x) = -4 log(x – 8) has the following features:

a. The domain is x > 8, because the expression x - 8 must be greater than 0 for the logarithm to be defined. Therefore, x must be greater than 8, so the domain is x > 8.

b. is incorrect because the range of the function is y < 0, not y > -8.

c. The value of the function decreases as x approaches positive infinity. As x gets larger and larger, the expression x - 8 gets larger and larger, so log(x - 8) gets larger and larger, approaching infinity. Multiplying by -4 makes the function more and more negative, so the value of the function decreases as x approaches positive infinity.

d. The value of the function does not increase as x approaches positive infinity, because as we just explained, the value of the function actually decreases as x approaches positive infinity. Therefore, option d is not correct.

Therefore, the correct answer is option c

1. A new basketball costs $22. 00 but is on sale for 40% off.


If sales tax is 5%, what is the final cost of the


basketball? Enter your answer as dollars and cents,

Answers

The final cost of the basketball, including sales tax, is $15.84.

What is the final price of the basketball, including sales tax, with a 40% discount on the original price of $22.00 and a 5% sales tax rate? Please provide the answer in dollars and cents.

The problem states that a new basketball costs $22.00, but it is on sale for 40% off. This means that the customer can purchase the basketball at a discount of 40% from its original price of $22.00.

To calculate the amount of discount, we multiply the original price of the basketball by the discount rate as a decimal:

Discount = 0.40 x $22.00 = $8.80

So, the sale price of the basketball would be:

Sale price = $22.00 - $8.80 = $13.20

Next, the problem states that the sales tax is 5%. Sales tax is a percentage of the sale price of the item, and it is added to the sale price to calculate the final cost of the item.

To calculate the amount of sales tax, we multiply the sale price by the sales tax rate as a decimal:

Sales tax = 0.05 x $13.20 = $0.66

Finally, to calculate the final cost of the basketball, we add the sale price and the sales tax:

Final cost = $13.20 + $0.66 = $15.84

Therefore, the final cost of the basketball, including sales tax, is $15.84.

someone please help

Answers

Using area formula for rectangles, we can find the new area of the rectangle to be 7350m².

The new dimensions are:

Length = 105m

Breadth = 70m

Define a rectangle?

A rectangle is a quadrilateral with parallel opposite sides and equal angles. There are a lot of rectangular objects all around us. Each rectangle's two defining characteristics are its length and breadth. A rectangle's longer and shorter sides are its width and length, respectively.

Here in the question,

Dimensions of the rectangle are as follows:

Length, l = 42m.

Width, w = 28m.

Scale factor here is 1: 5/2

Now,

Let the new width be x.

The new width will be:

28/x = 1/ (5/2)

Cross multiplying:

⇒ 28 × 5/2 = x

⇒ x = 70m.

So, new width = 70m.

Now, let new length be x.

So,

42/x = 1/ (5/2)

Cross multiplying:

⇒ x = 42 × 5/2

⇒ x = 105m.

So, the new length = 105m.

Now new area will be:

70 × 105

= 7350m².

Miguel draws a square on a coordinate plane. One vertex is located at (5, 4). The length of each side is 3 units. Circle the letter by all the ordered pairs that could be another vertex. ​

Answers

To find the other possible vertices of the square, we need to determine the coordinates of the other three vertices. Since we know that the length of each side is 3 units, we can use this information to determine the distance between the given vertex (5, 4) and the other vertices.

First, we can determine the direction of the square by looking at the given vertex and knowing that the sides of a square are equal in length and perpendicular. Since we know that the side length is 3 units, we can move 3 units to the right to find one possible vertex. This gives us the point (8, 4).

Next, we can move 3 units up to find another possible vertex. This gives us the point (5, 7).

Finally, we can move 3 units to the left to find the last possible vertex. This gives us the point (2, 4).

Therefore, the letter that should be circled by all the ordered pairs that could be another vertex is D, which represents the point (2, 4).

Find the area of this irregular shape hint area of a triangle a = bh÷2

Answers

Answer:

The area of the irregular shape is 62 feet

Explanation :

We are given with two shapes triangle and a rectangle.

From the above diagram

We can see that Breadth of the rectangle is 5 ft and length of 10 ft.

As we know that area of Rectangle is length × Breadth

Area(rectangle) = l × b

Area (rectangle) = 10 × 5

Area (rectangle) = 50 ft².

Now,

Area (triangle) = bh ÷ 2

where

b is base (10 - 6 = 4 ft)h = Height (11 - 5 =6 ft)

Area (triangle) = 4 × 6 ÷ 2

Area (triangle) = 24 ÷ 2

Area (triangle) = 12 ft².

Total area = Area of rectangle + Area of triangle

Total area = 50 + 12

Total area = 62 feet

Therefore, The area of the irregular shape is 62 feet.
