The length of the arc AD is approximately 5.24 cm.

What is the length of an arc in circle?

Length of arc = (angle of arc / 360°) x (circumference of circle)

Here, the angle of arc is given as 60° and the radius of the circle is given as 5 cm.

So, the circumference of the circle can be found as:

circumference of circle

[tex]= 2 \times π \times radius \\ = 2 \times π \times 5 \\ = 10π cm[/tex]

Using the formula for length of arc, we can find the length of AD as

length of AD = (angle of arc / 360°) x (circumference of circle)

= (60° / 360°) x (10π cm)

= (1/6) x (10π cm)

= (5/3)π cm

≈ 5.24 cm

Therefore, the length of the arc AD is approximately 5.24 cm.

What is inequalities?

In mathematics, an inequality is a mathematical statement that indicates that two expressions are not equal. It is a statement that compares two values, usually using one of the following symbols: "<" (less than), ">" (greater than), "≤" (less than or equal to), or "≥" (greater than or equal to).

To find the area of this quadrilateral, we can use the formula:

Area = 1/2 * |(x₁y₂ + x₂y₃ + x₃y₄ + x₄y₁) - (y₁x₂ + y₂x₃ + y₃x₄ + y₄x₁)|

where (x₁,y₁), (x₂,y₂), (x₃,y₃), and (x₄,y₄) are the coordinates of the vertices of the quadrilateral in order.

Substituting the values, we get:

Area = 1/2 * |(04 + 13 + 4*(-2) + 3*(-1)) - (-11 - 44 - 3*3 - (-2)*0)|

Area = 1/2 * |(-8 - 26)|

We can estimate that apprοximately 41 teachers vοlunteer at an animal shelter.

The given infοrmatiοn tells us that 40% οf the teachers vοlunteer as hοmewοrk tutοrs. We dο nοt knοw hοw many teachers there are in tοtal, sο we cannοt directly determine the number οf teachers whο vοlunteer at an animal shelter.

If 15% οf the teachers vοlunteer at a seniοr centre, 25% οf the teachers vοlunteer as spοrts cοaches, and 20% οf the teachers vοlunteer at an animal shelter, then the tοtal percentage οf teachers whο vοlunteer is:

15% + 25% + 20% + 40% = 100%

This means that all οf the teachers at the Blue Pacific Schοοl District vοlunteer in οne οr mοre οf these categοries.

Tο estimate the number οf teachers whο vοlunteer at an animal shelter, we can assume that the percentage οf teachers whο vοlunteer in each categοry is prοpοrtiοnal tο the number οf teachers whο vοlunteer in that categοry. If we let x be the tοtal number οf teachers at the schοοl district, then we can write:

0.15x = number οf teachers whο vοlunteer at a seniοr center

0.25x = number οf teachers whο vοlunteer as spοrts cοaches

0.20x = number οf teachers whο vοlunteer at an animal shelter

0.40x = number οf teachers whο vοlunteer as hοmewοrk tutοrs

Since we knοw that 82 teachers vοlunteer as hοmewοrk tutοrs, we can sοlve fοr x:

0.40x = 82

x = 205

Therefοre, there are 205 teachers in the Blue Pacific Schοοl District. Tο estimate the number οf teachers whο vοlunteer at an animal shelter, we can plug in x and 0.20x intο the equatiοn fοr the number οf teachers whο vοlunteer at an animal shelter:

The value of x for the given rectangle in which the perimeter of both the rectangle are equal is x = 15.

What about rectangle?

A rectangle is a four-sided plane figure with four right angles (90-degree angles) and opposite sides that are parallel and equal in length. In other words, it is a parallelogram with all angles being right angles. The two pairs of parallel sides of a rectangle are called the length and width (or height) respectively. The area of a rectangle is found by multiplying its length by its width, while its perimeter is found by adding up the lengths of all four sides. Rectangles are commonly used in mathematics, geometry, engineering, and architecture, among other fields.

Define perimeter of rectangle:

The perimeter of a rectangle is the total distance around the outside of the rectangle. It is the sum of the lengths of all four sides of the rectangle. If the length of the rectangle is denoted by "l" and the width (or height) is denoted by "w", then the formula for the perimeter of a rectangle is:

⇒ Perimeter = 2(l + w)

According to the given information:

As, we know that the perimeter of the rectangle is sum of all side of the rectangle in which,

The perimeter of first rectangle is =   [tex]2(1.4x + 5x + 5.25)[/tex]

The perimeter of second rectangle is = [tex]2(4.25x + 3x - 7.5)[/tex]

It is given that perimeter of both the rectangle are equal so,

2(1.4x + 5x + 5.25) = 2(4.25x + 3x - 7.5)

2.8x + 10x + 10.5  = 8.5x + 6x - 15

Answer:

Step-by-step explanation:

Answer:

Step 1: Find the previous balance.

After 8 payments, the remaining balance on the loan is $2,237.27. Therefore, the previous balance would be the balance before the 8th payment.

Total number of payments = 24

Number of payments already made = 8

Number of payments remaining = 24 - 8 = 16

Using the given monthly payment, we can find the balance before the 8th payment:

PV = PMT x [(1 - (1 + r/n)^-n*t)/(r/n)]

where PV is the present value or previous balance, PMT is the monthly payment, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the time period in years.

Plugging in the given values, we get:

PV = $147.37 x [(1 - (1 + 0.075/12)^(-12*2))/(0.075/12)]

PV = $3,090.60

Therefore, the previous balance was $3,090.60.

Step 2: Find the interest for the 9th month.

We know that the balance at the end of the 8th month was $2,237.27. We can use this and the given interest rate to find the interest for the 9th month.

Interest = Balance x (Annual interest rate/12)

Interest = $2,237.27 x (0.075/12)

Interest = $13.99

Step 3: Find the final payment.

To find the final payment, we need to add the interest for the 9th month to the monthly payment and subtract it from the remaining balance.

Final payment = Remaining balance + Interest for 9th month - Monthly payment

Final payment = $2,237.27 + $13.99 - $147.37

Final payment = $2,103.89

Therefore, the final payment is $2,103.89.

The Julia needs to sell at least 1,819 subs to break even each month with the new upscale repositioning of her sub shop.

1- To break even, Julia needs to cover all her costs which include labor costs, insurance, rent, and utilities along with the cost of ingredients and packaging.
Total fixed costs = Labor costs + Insurance + Rent + Utilities = $7,000 + $900 + $800 + $300 = $8,000
Total variable cost per sub = Average cost of ingredients/packaging = $1.15

To break even, Julia needs to sell enough subs to cover her fixed costs and variable costs.

Breakeven point = Fixed costs / (Price per sub - Variable cost per sub)
Breakeven point = $8,000 / ($6 - $1.15) = 1,778.26

Therefore, Julia needs to sell at least 1,779 subs to break even each month.

2- If Julia is able to lower the average cost of ingredients and packaging per sub to $0.95, then the new variable cost per sub becomes $0.95. All other costs remain the same.

Breakeven point = Fixed costs / (Price per sub - Variable cost per sub)
Breakeven point = $8,000 / ($6 - $0.95) = 1,723.68

Therefore, Julia needs to sell at least 1,724 subs to break even each month with the new lower cost of ingredients and packaging.

3- If Julia raises the price per sub to $10 and the variable cost per sub rises to $4.22, the new breakeven point becomes:

Breakeven point = Fixed costs / (Price per sub - Variable cost per sub)
Breakeven point = $8,000 / ($10 - $4.22) = 1,818.18

The formula to find the interquartile range (IQR) is:

IQR = Q3 - Q1

where Q1 and Q3 are the first and third quartiles, respectively. Since the distribution of weights of pumpkins is approximately normal, we can use the formula for the standard error of the mean to find the standard deviation of the sampling distribution of the mean:

SEM = σ / sqrt(n)

where σ is the population standard deviation, n is the sample size, and sqrt represents the square root function.

Plugging in the given values, we get:

SEM = 1.68 / sqrt(15)

≈ 0.4334

To find the first and third quartiles, we need to find the z-scores corresponding to the 25th and 75th percentiles of the standard normal distribution, respectively. These z-scores can be found using a standard normal distribution table or a calculator.

Using a standard normal distribution table, we find that:

Therefore, the first and third quartiles are:

Q1 = μ + z1 * SEM

= 8.3 - 0.6745 * 0.4334

≈ 7.998

Q3 = μ + z3 * SEM

= 8.3 + 0.6745 * 0.4334

≈ 8.602

Finally, we can calculate the interquartile range (IQR) as:

IQR = Q3 - Q1

≈ 8.602 - 7.998

≈ 0.604

Rounding to the nearest thousandth, we get:

IQR ≈ 0.604

Therefore, the value of the interquartile range (IQR) for the mean weight of 15 pumpkins is 0.604 pounds.

Answer:

rational function is:

f(x) = (x² - 4x - 5) / (x - 9)

To find f(5), we substitute x = 5:

f(5) = (5² - 4(5) - 5) / (5 - 9) = (-10) / (-4) = 5/2

To find f(9), we substitute x = 9:

f(9) = (9² - 4(9) - 5) / (9 - 9) = undefined

The function value f(9) is undefined because the denominator becomes zero, which makes the expression undefined.

To find f(7), we substitute x = 7:

f(7) = (7² - 4(7) - 5) / (7 - 9) = (-10) / (-2) = 5

Therefore, the function values are:

f(5) = 5/2

f(9) = undefined

f(7) = 5
