a) calculate the length of the arc.

b) calculate the area of the sector.

c) calculate the area of the segment in the sector with the angle of 3π/10 rad and a radius of 5cm.​

Answers

Answer 1

Step-by-step explanation:

3pi / 10 * 180 / pi = 54 degrees.

The circumference of the circle would be 10 pi. Multiply this by 54/360 to get 1.5pi or 3 pi /2

Area of the circle would be 25 pi. Multiply this by 54/360 to get 3.75 pi or 15pi /4

I'm confused on part (c), is it not just the same question as part (b)?

All these answers are assuming that 3pi/10 is the central angle. If it is an inscribed angle, then the central angle would be 6pi/10 or 3pi/5.

Edit: if part (c) is talking about inscribed angle, then the degrees would be 108. Then you just multiply 25pi by 108/360 for your answer

A box of tissues is 13cm in height and 11 cm in length. Its volume is 1501.5 cm cubed. What is the width, of the box of tissues?

Answers

The width of the box of tissues is approximately 10.49 cm.

How to find the width of the box of tissues

We can use the formula for the volume of a rectangular prism:

Volume = Length × Width × Height

We may rearrange the formula to find the breadth if we know the volume is 1501.5 cm3 and the length is 11 cm:

Width = Volume / (Length × Height)

Substituting the given values:

Width = 1501.5 cm³ / (11 cm × 13 cm)

Width = 1501.5 cm³ / 143 cm²

Calculating the result:

Width ≈ 10.49 cm

So, the width of the box of tissues is approximately 10.49 cm.

The population of a town has been growing, following the equation p= 200t+4500
, where t is years after 2010. The number of restaurants in the town has been growing according to the equation R=6t+35
.

Complete an equation for the number of restaurants per capita (per person)

Restaurants per capita:


How many restaurants per capita does this model predict for the year 2016?

Answers

The model predicts that there are approximately 0.012456 (71/5700) restaurants per capita in the year 2016

To determine the number of restaurants per capita, we need to divide the number of restaurants (R) by the population (p). Given that R = 6t + 35 and p = 200t + 4500, we can substitute these values into the equation for restaurants per capita.

Restaurants per capita = R / p

Substituting the given equations, we get:

Restaurants per capita = [tex](6t + 35) / (200t + 4500)[/tex]

To find the number of restaurants per capita for the year 2016, we need to calculate the value of t for that year. Since t represents years after 2010, in 2016, t would be 6 (2016 - 2010 = 6).

Restaurants per capita (2016) = [tex](6 * 6 + 35) / (200 * 6 + 4500)[/tex]

= [tex](36 + 35) / (1200 + 4500)[/tex]

= 71 / 5700

This means that, on average, there is roughly one restaurant for every 80 people in the town. Please note that this prediction is based on the given growth equations and assumes a linear relationship between population and the number of restaurants.

Pearl writes down seven consecutive integers, and adds them up. The sum of the integers is equal to $\frac{21}{4}$ times the largest of the seven integers. What is the smallest integer that Pearl wrote down?

Answers

The smallest integer that Pearl wrote down is -12.Let's assume the smallest integer that Pearl wrote down is represented by the variable "x."

According to the given information, the sum of the seven consecutive integers is equal to $\frac{21}{4}$ times the largest integer.

The sum of consecutive integers can be expressed as the sum of an arithmetic series. The sum of an arithmetic series can be calculated using the formula:

Sum = (n/2)(first term + last term)

In this case, the first term is x and the last term is x + 6 (since there are seven consecutive integers). Therefore, the sum of the integers can be written as:

Sum = (7/2)(x + (x + 6))

Simplifying the equation:

(7/2)(2x + 6) = (21/4)(x + 6)

Multiplying both sides by 4 to eliminate the fractions:

14x + 42 = 21x + 126

Subtracting 14x from both sides:

42 = 7x + 126

Subtracting 126 from both sides:

-84 = 7x

Dividing both sides by 7:

-12 = x.

A gardener has 800 feet of fencing to fence in a rectangular garden. One side of the garden is bordered by a river and so it does not need any fencing.

garden bordered by a river

What dimensions would guarantee that the garden has the greatest possible area?

shorter side:
ft (feet)

longer side:
ft (feet)

greatest possible area:
ft2 (square-feet)

Answers

The garden will have the greatest possible area of 80,000 square feet when the shorter side is 400 feet, the longer side is 200 feet, and the garden is bordered by a river on one side.

To find the dimensions that guarantee the garden has the greatest possible area, we can use the concept of optimization.

Let's assume the shorter side of the rectangular garden is x feet.

Since one side of the garden is bordered by a river and doesn't require fencing, we only need to fence three sides of the garden.

The perimeter of the garden is given by the sum of the lengths of the three sides, which is equal to 800 feet.

Thus, we have:

x + 2L = 800

Solving for L (the longer side of the garden) in terms of x:

L = (800 - x)/2

The area of the rectangular garden is given by the product of its length and width, which is:

Area = x [tex]\times[/tex] L

Substituting the expression for L in terms of x:

Area = x [tex]\times[/tex] [(800 - x)/2]

To find the dimensions that guarantee the greatest possible area, we need to find the maximum value of this area.

We can do this by differentiating the area function with respect to x, setting it equal to zero, and solving for x:

d(Area)/dx = (800 - 2x)/2 = 0

800 - 2x = 0

2x = 800

x = 400

So, the shorter side of the garden should be 400 feet.

Substituting this value back into the expression for L:

L = (800 - 400)/2 = 200

Therefore, the longer side of the garden should be 200 feet.

Finally, to find the greatest possible area, we can substitute the values of x and L into the area formula:

Area = 400 [tex]\times[/tex] 200 = 80,000 square feet.

To solve the equation (24/32) = (RV/16), we can cross-multiply and solve for RV.

Cross-multiplying gives us

4x+2y=24,3x-4y=7.To find the elimination method

Answers

Answer:

  (x, y) = (5, 2)

Step-by-step explanation:

You want to use the elimination method to solve these equations:

4x +2y = 243x -4y = 7

Elimination method

To solve the equations by the elimination method you want to combine them in such a way that the coefficient of one of the variables is zero.

The coefficients of x are 4 and 3, so we can eliminate the x variable by multiplying the first equation by 3 and the second equation by -4 before we combine (add) them.

The coefficients of y are 2 and -4, so we can eliminate the y variable by multiplying the first equation by 2 before we combine (add) them. This seems simpler.

  2(4x +2y) +(3x -4y) = 2(24) +(7)

  11x = 55 . . . . . . . . simplify

  x = 5 . . . . . . . . divide by 11

  4(5) +2y = 24 . . . . . . substitute for x in the first equation

  2y = 24 -20 . . . . . subtract 20

There will be a filled-in hole at -4.

Step-by-step explanation:

We can solve an inequality the same way we do for equations. The only thing to keep in mind, is that multiplying by a negative number will result in flipping the inequality sign (< to > and vice versa)

[tex]-7x + 13 \geq 41 \text{ //}-13\\-7x \geq 28 \text{ //}:-7 \text{ (Notice we multiply by a negative number.)}\\x \leq -4[/tex]

The difference between a filled-in and an empty hole in terms of inequality graphs, is whether or not the number limiting the inequality is included in it.

For example, in x > 3, 3 is limiting the inequality, however, it is not included in it, therefore, x would always be greater than 3.

In another example, [tex]x \leq -4[/tex], -4 is limiting inequality and is included in it. Therefore, x would always be less than or equal to -4.

A filled-in hole means the number is included in the inequality, while an empty one means it isn't.

In our cases, -4 is included in the inequality (notice the line under the inequality sign that resembles "less than or equal to"), therefore there will be a filled-in hole at -4.

Answers

None of the provided options (A, B, C, D) matches the correct surface area of the prism, which is 210 square inches.

To find the surface area of the prism, we need to calculate the area of each face and then sum them up.

Let's calculate the areas of each face:

Rectangle 1: Area = base × height = 13 × 5 = 65 square inches

Rectangle 2: Area = base × height = 12 × 5 = 60 square inches

Rectangle 3: Area = base × height = 5 × 5 = 25 square inches

Triangle 1: Area = (base × height) / 2 = (12 × 5) / 2 = 30 square inches

Triangle 2: Area = (base × height) / 2 = (12 × 5) / 2 = 30 square inches

Step 2: Sum up the areas of all the faces.

Total Surface Area = Area of Rectangle 1 + Area of Rectangle 2 + Area of Rectangle 3 + Area of Triangle 1 + Area of Triangle 2

Total Surface Area = 65 + 60 + 25 + 30 + 30

Total Surface Area = 210 square inches

Therefore, the surface area of the prism is 210 square inches.

Now, let's sum up the areas of all the faces:

Total surface area = 65 + 60 + 25 + 30 + 30 = 210 square inches

If 25 people can do a task in 6 hours, how long would it take 15 people to do the same task?

Answers

It would take 15 people approximately 3.6 hours to complete the same task.

To solve this problem, we can use the concept of the work done. Work is defined as the product of the number of people and the time taken to complete a task.

Let's assume that the amount of work required to complete the task is represented by W. We know that 25 people can do the task in 6 hours, so the work done by 25 people in 6 hours is 25 * 6 = 150 person-hours.

Now, we need to find out how long it would take 15 people to do the same task. Let's represent the time taken by 15 people to complete the task as T.

Since the amount of work required to complete the task is the same, we can set up a proportion:

25 people / 6 hours = 15 people / T hours

Cross-multiplying, we get:

25 * T = 15 * 6

Simplifying, we find:

25T = 90

Dividing both sides by 25, we obtain:

T = 90 / 25 = 3.6 hours

at the end of July?
Raw material inventory balance
$ 257,250

Answers

The estimated raw material Inventory balance at the end of July is $27,750.

The estimated raw material inventory balance at the end of July, we need to follow the given information and calculations:

a. Each unit of finished goods requires 5 pounds of raw materials. Therefore, the total raw materials needed for production in August can be calculated as follows:

23,000 units (budgeted unit sales for September) × 5 pounds/unit = 115,000 pounds

b. The ending raw materials inventory equals 10% of the following month's raw materials production. Based on the information provided, the estimated raw materials needed to meet production in August is 111,000 pounds.

111,000 pounds × 0.10 (10%) = 11,100 pounds

This means that the ending raw materials inventory for July should be 11,100 pounds.

c. The cost of raw materials is $2.50 per pound. To find the value of the raw material inventory at the end of July, we multiply the pounds by the cost per pound:

11,100 pounds × $2.50/pound = $27,750

Therefore, the estimated raw material inventory balance at the end of July is $27,750.

Mr.
Morake's municipal bill showed R201,27, for water usage at the end of august 2018 , He stated that the basic charge was not included on the water . is the state true?

Answers

No, Mr. Morake's statement is not true.

The basic charge is included in the water usage bill. The basic charge is a fixed fee that is charged to all customers, regardless of their water usage. It helps to cover the costs of maintaining the water infrastructure, such as the water mains and pipes. The basic charge for Mr. Morake's property is R150.00. This means that the total amount of his water bill should be R216.27, not R201.27.

Here is a breakdown of Mr. Morake's water bill:

* Basic charge: R150.00

* Water usage: R51.27

* Total: R201.27

It is possible that Mr. Morake is confused about the difference between the basic charge and the water usage charge. The basic charge is always included in the water bill, while the water usage charge is only charged if you use more than a certain amount of water. In Mr. Morake's case, he used more than the amount of water that is exempt from the water usage charge, so he was charged the full water usage amount.

which of the following statement is not true about sin theta, where theta is 2π/3 radians.

a) it has the same value as sin(8π/3)
b) it has the same value as sin30°
c) it has a positive value
d) it has a negative value​

Answers

Step-by-step explanation:

2pi/3 is the same thing as 2pi/3 * 180/pi = 120 degrees

From your choices, we know that it is either c or d.

sin(120) is in the 2nd quadrant, so the x is negative and the y is positive. Remember that sin corresponds to the y value, so it is positive. Therefore option (d) is not true.

Answers

The solutions to the equation sin(θ) + 1 = cos(2θ) on the interval 0 ≤ θ ≤ 2π are θ = 0, θ = π, θ = 7π/6, and θ = 11π/6.

To solve the equation sin(θ) + 1 = cos(2θ) on the interval 0 ≤ θ ≤ 2π, we can use trigonometric identities and algebraic manipulations to simplify and find the solutions.

Let's start by using the double-angle identity for cosine:

cos(2θ) [tex]= 1 - 2sin^2(\theta)[/tex]

Substituting this into the equation, we have:

[tex]sin(\theta) + 1 = 1 - 2sin^2(\theta)[/tex]

Rearranging the equation, we get:

[tex]2sin^2(\theta) + sin(\theta) = 0[/tex]

Factoring out sin(θ), we have:

sin(θ)(2sin(θ) + 1) = 0

Now we can set each factor equal to zero and solve for θ:

sin(θ) = 0 or 2sin(θ) + 1 = 0

For sin(θ) = 0, the solutions are θ = 0 and θ = π (since sin(θ) = 0 at these values on the interval 0 ≤ θ ≤ 2π).

For 2sin(θ) + 1 = 0, we can solve for sin(θ):

2sin(θ) + 1 = 0

2sin(θ) = -1

sin(θ) = -1/2

The solutions for sin(θ) = -1/2 on the interval 0 ≤ θ ≤ 2π are θ = 7π/6 and θ = 11π/6.

1) The area of a circle circumscribed about a square is 307.7 cm².

2.a.) The angle ACB is 39 degrees.°.

2b.) The value of x is 5.42.

How to determine the area of a circle?

We shall find the radius to determine the area of a circle.

First,  find the side length of the square:

Since the perimeter of the square = 56 cm, then, each side of the square is 56 cm / 4 = 14 cm.

Next, find the diagonal of the square, using the Pythagorean theorem:

Diagonal = the diameter of the circumscribed circle.

Diagonal² = side length² + side length²

= 14 cm² + 14 cm²

= 196 cm² + 196 cm²

= 392 cm²

Take the square root of both sides:

Diagonal = √392 cm ≈ 19.80 cm (rounded to two decimal places)

Then, the radius of the circle which is half the diagonal:

Radius = Diagonal / 2 ≈ 19.80 cm / 2 ≈ 9.90 cm (rounded to two decimal places)

Finally, compute the area of the circle using the formula:

Area = π * Radius²

Area = 3.14 * (9.90 cm)²

Area ≈ 307.7 cm² (rounded to two decimal places)

Therefore, the area of the circle that is circumscribed about a square with a perimeter of 56 cm is 307.7 cm².

2. a) We use the property of angles in a circle to solve for angle ACB: an angle inscribed in a circle is half the measure of its intercepted arc.

Given that arc AB has a measure of 78°, we can find angle ACB as follows:

Angle ACB = 1/2 * arc AB

= 1/2 * 78°

= 39°

Therefore, the angle ACB is 39 degrees.

2b.) To solve for the value of x, we use the information that the angle ADB =  (3x - 12)⁴.

Given that angle ADB is (3x - 12)⁴, we can equate it to the measure of the intercepted arc AB, which is 78°:

(3x - 12)⁴ = 78

Solve the equation for x, by taking the fourth root of both sides:

∛∛((3x - 12)⁴) = ∛∛78

Simplify,

3x - 12 = ∛(78)

Isolate x by adding 12 to both sides:

3x - 12 + 12 = ∛(78) + 12

3x = ∛(78) + 12

Finally, divide both sides by 3:

x = (∛(78) + 12) / 3

x = (4.27 +12) / 3

x = 5.42

So, x is 5.42

Therefore,

1) The area of the circle is 154 cm².

2a.) Angle ACB is equal to 102°.

2b.) The value of x is 5.42

Understanding Linear Equation

Linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a single variable raised to the power of 1. In other words, it represents a straight line when graphed on a coordinate plane.

The general form of a linear equation is:

ax + by + c = 0

Here, "x" and "y" are variables, and "a," "b," and "c" are constants.

For example, the equation y = 2x + 3 is a linear equation with one variable (x) and represents a straight line on a graph. The coefficients 2 and 3 determine the slope and y-intercept of the line, respectively.
