The average rent of a one-bedroom apartment in Brooklyn is estimated to be $2,836.69 in 2023 after the 2.5% increase in both 2022 and 2023

What is the percentage increase?

Percentage increase is a measure of how much a value or quantity has increased relative to its original value, expressed as a percentage.

To calculate the percentage increase, you can use the following formula:

Percentage increase = (New value - Old value) / Old value x 100%

If the average rent of a one-bedroom apartment in Brooklyn is $2,700 in 2021, and it increases by 2.5% in both 2022 and 2023, we can calculate the average rent in 2023 as follows:

Calculate the increase in rent due to the 2.5% increase in 2022:

2.5% of $2,700 = 0.025 x $2,700 = $67.50

The new rent in 2022 will be $2,700 + $67.50 = $2,767.50

Calculate the increase in rent due to the 2.5% increase in 2023:

2.5% of $2,767.50 = 0.025 x $2,767.50 = $69.19

The new rent in 2023 will be $2,767.50 + $69.19 = $2,836.69

Therefore, the average rent of a one-bedroom apartment in Brooklyn is estimated to be $2,836.69 in 2023 after the 2.5% increase in both 2022 and 2023.

piecewise function defines the function graphed between y=2x+3 and y=-1/3x+3.

How to compare linear equations?

The comparison method, a procedure for solving systems of independent equations, starts by rewriting each equation with the same variable as the subject.

If 60 dogs are registered in Castroville, we can find the number of Golden Retrievers and Boxers by using the given percentages.

Number of Golden Retrievers = 0.45 x 60 = 27

Number of Boxers = 0.55 x 60 = 33

To find how many more Boxers there are than Golden Retrievers, we can subtract the number of Golden Retrievers from the number of Boxers:

Boxers - Golden Retrievers = 33 - 27 = 6.

Therefore, there are 6 more Boxers than Golden Retrievers in the group of 60 registered dogs in Castroville.

The given information only provides the percentages of Golden Retrievers and Boxers among registered dogs in Castroville, so we don't have enough information to directly calculate the percentage of all other dog breeds. However, we know that the total percentage of all dog breeds must add up to 100%. Since Golden Retrievers and Boxers make up 45% and 55% of the registered dogs, respectively, the percentage of all other dog breeds must be 100% - 45% - 55% = 0%. This means that there are no other registered dog breeds in Castroville, and all registered dogs belong to either the Golden Retriever or Boxer breed.

Answer:

  0.255 or 25.5%

Step-by-step explanation:

You want the scale factor that reduces 5.1 inches to 1.3 inches.

The scale factor is the ratio of the image size to the original size:

  1.3/5.1 ≈ 0.254902 ≈ 0.255 = 25.5%

__

Additional comment

A scale factor of 0.255 would give an image of 1.3005 inches. That's probably close enough. Rounding to the nearest percent, it would be 25%, which would give an image size of 1.275 inches.

since we know the number is doubling, so if say it was "x" right now so 30 minutes later will be "x" + 100 of "x", namely 2x, so that simply means the rate of growth is 100%.

45 and 27.6 degrees are the two complementary angles.

When the right angle is split into two equal parts, each angle is 45°. A 45-degree angle is considered sharp. It is a right angle of half, or a 90-degree angle.

Angles that are complementary are those whose sum is 90 degrees. If the smaller angle has a measure of x, then the complementary angle's measure is 90 - x.

The issue shows that the greater angle (x + 17.4) is 17.4 degrees larger than the corresponding angle's measurement (90 - x). To find x, we can construct the following equation:

x + 17.4 = 90 - x + 17.4

When we simplify and find x, we obtain:

2x = 55.2

x = 27.6

The greater angle's measure is x + 17.4 = 45 degrees, while the smaller angle's measure is x = 27.6 degrees.

The two complementary angles are 27.6 and 45 degrees as a result.

The minimum cost after assigning the jobs to different machines is 48. The solution has been obtained by using the cost function.

What is a cost function?

For some fixed factor prices, the cost function calculates the lowest cost of generating a specified level of output. The economic potential of a corporation is described by the cost function.

According to the cost function, the optimal assignment in order to minimise the total cost is by assigning:

Job J1 to machine M2 having a cost of 11

Job J2 to machine M3 having a cost of 12

Job J3 to machine M1 having a cost of 14

Job J4 to machine M4 having a cost of 11

From this, we get the total minimum cost as:

11 + 12 + 14 + 11 = 48

a. The composite function is N(T(t)) = 290t² - 380t + 386.44

b. the number of bacteria after 5.3 hours is 6519 bacteria.

A function is a mathematical equation that shows the relationship between two variables.

A composite function is a function which contains another function.

Since the number of bacteria in a refrtgerated food product is given by N(T) = 29T² - 76T + 30 , 3 < T < 33 where T is the temperature of the food.

Also, when the food is removed from the refrigerator, the temperature is given by T(t) = 5t + 1.4 where t where t is the time in hours.

So, to find the composite function N(T(t)), we substitute T(t) into N(T).

So,

N(T) = 29T² - 76T + 30

N(T(t)) = 29(5t + 1.4)² - 76(5t + 1.4) + 30

Expanding the brackets, we have that

N(T(t)) = 29(10t² + 14 + 1.96) - 76(5t + 1.4) + 30

N(T(t)) = 290t² + 406 + 56.84 - 380t - 106.4 + 30

N(T(t)) = 290t² - 380t + 406 + 56.84 - 106.4 + 30

N(T(t)) = 290t² - 380t + 386.44

So, the function is N(T(t)) = 290t² - 380t + 386.44

Since N(T(t)) = 290t² - 380t + 386.44 is the number of bacteria after t hours.

To find the number of bacteria after 5.3 hours, we substitute t = 5.3 into the equation.

So,

N(T(t)) = 290t² - 380t + 386.44

N(T(5.3)) = 290(5.3)² - 380(5.3) + 386.44

N(T(5.3)) = 290(28.09) - 380(5.3) + 386.44

N(T(5.3)) = 8146.1 - 2014 + 386.44

N(T(5.3)) = 6518.54

N(T(5.3)) ≅ 6519 bacteria

Answer: Around 9,284 books.

Step-by-step explanation:

   First, we will find how large this sample is by using addition.

753 + 74 + 30 = 857

   Next, since we are looking for the expected minor or major damage, we will find the number of books from this sample that meet the requirements.

74 + 30 = 104

   Now, we will find the percentage of this sample that meets the criteria.

(104 / 857) * 100 ≈ 12.13536%

   Lastly, we will use this value to determine how many books in the collection are likely to have minor or major damage.

76,500 * 12.13536% = 9,283.55 ≈ 9,284 books

Answer:

Mrs. Parker should expect around 9284 books in the library's collection to have minor damage or major damage.

Step-by-step explanation:

To calculate the expected number of books with minor or major damage in the entire collection, we can scale up the sample proportion to the size of the full collection.

First, let's find the proportion of books with minor or major damage in the sample:

Proportion = (74 + 30) / (753 + 74 + 30) = 104 / 857 = 0.1214

Next, we'll scale up this proportion to the size of the full collection:

expected number of books with minor or major damage = proportion * 76,500 = 0.1214 * 76,500 = 9283.5472578763

Finally, we round the result to the nearest whole number:

expected number of books with minor or major damage = round(9283.5472578763 ) = 9284

So, Mrs. Parker should expect around 9284 books in the library's collection to have minor damage or major damage.

Answer:

The measure of angle ∠T found using the law of sines is about 72°

The law of sines states that the ratio of the of the sine of an angle in a triangle to the length of the opposite side, is the same for the three angles in a triangle.

Mathematically, where the side lengths of the triangle are; a, b, c, and the corresponding opposite angles are ∠A, ∠B, and ∠C, we get;

[tex]\frac{sin(A)}{a} = \frac{sin(B)}{b} = \frac{sin(C)}{c}[/tex]

The parameters in the question are;

AT = 28

AD = 37

m∠D = 46°

DT = a

Therefore, according to the law of sines, we get;

37/(sin∠T) = 28/(sin(46°))

Inverting both sides, we get;

(sin∠T)/37 = (sin(46°))/28

An algebraic expression is a combination of variables, numbers, and mathematical operations, such as addition, subtraction, multiplication, and division. It can be used to represent a mathematical relationship or formula and can be simplified or evaluated using algebraic rules.

If Victoria signed up for a gym membership 21 weeks after Monica and we let a represent the number of weeks Victoria has been a member and b represent the number of weeks Monica has been a member, then we have a = b + 21.

Substituting a = 9, we get:

b = 9 - 21
