Determine whether AB and CD are parallel, perpendicular, or neither. A(-3, 2), B(5, 1), C(2, 7), D(1, -1)

Answers

Answer 1

Answer:

perpendicular

Step-by-step explanation:

We'll find the slope of both lines and see what it tells us.

If the slopes are the same, the lines are parallel. If the slopes are opposite sign and flipped (negative reciprocals) then they are perpendicular.

The slope is y-Y on top of a fraction and x-X on the bottom.

Slope of AB:

m = 2-1 / -3 -5

= 1/-8 = -1/8

Slope of CD:

m = 7- -1 / 2-1

= 8/1 = 8

Since the slopes are -1/8 and 8, the lines are perpendicular, because they are opposite sign and flipped (negative reciprocals)

A manager drew this box-and-whisker plot to represent the number of minutes each of his 27 employees took on their break. Each employee took a different amount of time.

How many employees took a break longer than 49 minutes?

Help please!
Note: Put the correct answer! I don't want to get this wrong!

Thank you <3

Answers

Approximately 7 employees took a break longer than 49 minutes.

We have,

In a box-and-whisker plot, the box represents the interquartile range (IQR), which includes the middle 50% of the data.

The line within the box represents the median.

The "whiskers" extend to the minimum and maximum values, excluding any outliers.

Given the information provided:

Median = 41

Q1 = 37

Q3 = 49

Largest = 55

Smallest = 35

Since Q3 represents the upper quartile and corresponds to the boundary for the upper 25% of the data, we can conclude that 25% of the employees took a break longer than 49 minutes.

Now,

The number of employees who took a break longer than 49 minutes can be estimated by calculating 25% of the total number of employees:

25% of 27 employees

= (25/100) x 27

= 6.75

Since we cannot have a fractional number of employees, we round up to the nearest whole number.

Therefore,

Approximately 7 employees took a break longer than 49 minutes.

The value of c in the polynomial is - 7.

How to solve polynomials?

The polynomial is given as follows:

p(x) = 2x³ - x² +  cx + 2 . The value of c if x - 2 is a factor of p(x) can be computed as follows:

Therefore,

p(x) = 2x³ - x² +  cx + 2

when x - 2 is a factor, p(x) = 0

Therefore,

0 = 2x³ - x² +  cx + 2

Hence,

2(2)³ - (2)² +  2c + 2 = 0

16 - 4 + 2c + 2 = 0

A survey of 800 nurses yielded the following information. 555 were health club members, 430 were smokers, and 320 of the health club members were smokers. How many of the 800 surveyed nurses were health club members or were smokers

Answers

Step-by-step explanation:

800 in total.

555 health club members.

430 smokers.

320 health club members (that means out of the total of 555) were smokers.

that means that

555 - 320 = 235 health club members were not smokers.

and out of the 430 smokers 320 were also health club members.

that means that

430 - 320 = 110 smokers were not health club members.

the question how many were health club members or smokers means how many people were either health club members or smokers.

so, we need to combine the sets of health club members and smokers.

the number of elements in the resulting set is not just the sum of elements of both sets, because some elements are in both sets and would be counted twice.

therefore, we have a few alternatives :

1. add both sets and then subtract the common part (people being in both sets), as this removes the double counting :

555 + 430 - 320 = 665

2. start with the common part (people that are in both sets) and add the extra people in both sets (health club members that do not smoke, and smokers that are not health club members) :

320 + 235 + 110 = 665

3. start with one of the full sets (e.g. all health club members) and add the extra people of the other set (all smokers that are not also health club members) :

555 + 110 = 665

or all smokers plus all health club members that were not smokers :

430 + 235 = 665

as you can see, as expected, the answer is always the same :

out of the 800 nurses 665 were health club members or smokers.

We have,

Based on the given transactions, we can prepare the accounting equation as follows:

a. Started business with Cash Rs. 250,000.

Assets: Cash = Rs. 250,000

b. Purchased goods amounting to Rs. 45,000 on credit from Harish.

Assets: Cash = Rs. 250,000, Inventory = Rs. 45,000

Liabilities: Accounts Payable = Rs. 45,000

c. Goods costing to Rs. 80,000 was sold for Rs. 1,25,000 on credit.

Assets: Cash = Rs. 250,000, Accounts Receivable = Rs. 1,25,000

Inventory: Rs. 45,000 - Rs. 80,000 = Rs. -35,000 (Assuming no additional purchases or returns)

Liabilities: Accounts Payable = Rs. 45,000

Capital: Retained Earnings = Rs. 1,25,000 - Rs. 80,000 = Rs. 45,000

d. Salaries outstanding Rs. 5,000.

Liabilities: Salaries Payable = Rs. 5,000

e. Rent paid Rs. 50,000.

Assets: Cash = Rs. 250,000 - Rs. 50,000 = Rs. 2,00,000

f. Withdrawn by owner for personal use Rs. 25,000.

Assets: Cash = Rs. 2,00,000 - Rs. 25,000 = Rs. 1,75,000

Capital: Retained Earnings = Rs. 45,000 - Rs. 25,000 = Rs. 20,000

Now, let's summarize the accounting equation:

Assets:

Cash = Rs. 1,75,000

Inventory = Rs. -35,000 (negative value indicates loss or returns)

Liabilities:

Accounts Payable = Rs. 45,000

Salaries Payable = Rs. 5,000

You have $400,000 saved for retirement. Your account earns 10% interest. How much will you be able to pull out each month, if you want to be able to take withdrawals for 20 years?

Answers

You will be able to withdraw $3,548.50 per month for 20 years if you have $400,000 saved for retirement and earn 10% interest.

To calculate the monthly withdrawals for a given time period, we can use the present value annuity formula. This formula allows us to calculate the fixed monthly withdrawal amount needed to deplete a given initial amount (in this case, $400,000) over a specified time period (20 years) at a given interest rate (10%).

The formula for present value annuity is:

PMT = PV * r / (1 - (1 + r)⁻ⁿ)

Where:

PMT = the fixed monthly withdrawal amount

PV = the present value of the initial investment ($400,000)

r = the interest rate per month (10%/12 = 0.00833)

n = the total number of monthly withdrawals (20 years * 12 months per year = 240)

Plugging in the values, we get:

PMT = 400,000 * 0.00833 / (1 - (1 + 0.00833)⁻²⁴⁰) = $3,548.50 (rounded to the nearest cent)

Find the surface area of the composite solid to the nearest hundredth.

A composite solid of a square prism with a square pyramid extending from the top and bottom face of the prism. The width, length, and height of the prism are all 5 inches. The slant height of the pyramid on the bottom of the prism is 7.5 inches. The height of the pyramid on top of the prisim is 3 inches.

Answers

The surface area of the composite solid is 255 square inches.

How to find the surface area of the composite solid?

We will compute the surface area of each component and then add them together to find the surface area of the composite solid.

First, the surface area of the square prism:

Given: The square prism has a width, length, and height of 5 inches each.

Formula for the surface area of a rectangular prism: 2lw + 2lh + 2wh

Surface area of the prism = 2(5 * 5) + 2(5 * 5) + 2(5 * 5)

= 2(25) + 2(25) + 2(25)

= 50 + 50 + 50

= 150 square inches

Next, the surface area of the square pyramid at the bottom:

Given: The slant height of the pyramid on the bottom of the prism = 7.5 inches.

The base of the pyramid is a square with a side length of 5 inches.

Formula to find the lateral surface area of a square pyramid: (perimeter of base) * slant height / 2.

The base is a square, the perimeter is 4 times the side length.

Lateral surface area of the bottom pyramid = (4 * 5) * 7.5 / 2

= 20 * 7.5 / 2

= 150 / 2

= 75 square inches

Then, the Surface area of the square pyramid at the top:

Given: The height of the pyramid on top of the prism = 3 inches.

The base of the pyramid is a square with a side length of 5 inches.

Lateral surface area of the top pyramid = (4 * 5) * 3 / 2

= 20 * 3 / 2

= 60 / 2

= 30 square inches

Finally, we shall find the total surface area by summing up the surface areas of each component in this way:

Total surface area = Surface area of the prism + Surface area of the bottom pyramid + Surface area of the top pyramid

= 150 + 75 + 30

= 255 square inches

Therefore, the surface area of the composite solid = 255 square inches.

John borrowed $4,300.00 for 8 days at an annual simple interest rate of 13.75%. What is the amount of interest will John have to pay at the end of the loan?

Answers

John will have to pay $12.24 in interest at the end of the loan.

To calculate the amount of interest John will have to pay at the end of the loan, we can use the formula for simple interest:

Interest = Principal * Rate * Time

Given:

Principal (P) = $4,300.00

Rate (R) = 13.75% per annum

Time (T) = 8 days

First, we need to convert the rate from an annual percentage to a daily rate. Since there are 365 days in a year:

Daily Rate = (Rate / 100) / 365 = (13.75 / 100) / 365 = 0.0003767

Now we can calculate the interest:

Interest = Principal * Rate * Time

= $4,300.00 * 0.0003767 * 8

= $12.24

Therefore, John will have to pay $12.24 in interest at the end of the loan.

Triangle ABC is the preimage of a transformation that consists of a reflection across x -axis followed by a reflection across the y -axis. Which of the triangles is the image of △ABC under this transformation? Select the triangle that corresponds to the image △A′B′C′ .

Answers

The image triangle △A'B'C' is formed by reflecting triangle ABC across the origin, resulting in each point's coordinates being negated.

The preimage triangle ABC undergoes a reflection across the x-axis followed by a reflection across the y-axis.

To determine the image triangle △A'B'C', we need to understand the effects of these transformations.

Reflection across the x-axis flips the points of the preimage vertically, while reflection across the y-axis flips the points horizontally.

When both reflections are applied successively, the resulting image will be a reflection across the origin (0,0).

Given that, the image triangle △A'B'C' will be the reflection of triangle ABC across the origin.

In this case, the x-coordinate and y-coordinate of each point in triangle ABC will be negated to obtain the corresponding point in △A'B'C'.

Let's consider the points of triangle ABC:

A(x₁, y₁), B(x₂, y₂), C(x₃, y₃)

To obtain the corresponding points in △A'B'C', we negate the x and y coordinates:

A'(-x₁, -y₁), B'(-x₂, -y₂), C'(-x₃, -y₃)

Therefore, the image triangle △A'B'C' is formed by reflecting triangle ABC across the origin, resulting in each point's coordinates being negated.

Note: It's important to note that without the actual coordinates of triangle ABC, it's not possible to determine the specific shape or size of the image triangle △A'B'C'.

Vanessa makes 7 identical flower arrangements for the tables at a banquet. Each arrangement contains some roses and 9 tulips. Vanessa uses a total of 147 flowers to make the arrangements. How many roses are in each arrangement?​

Answers

Let's assume the number of roses in each arrangement is represented by "r".

Since Vanessa makes 7 identical flower arrangements, the total number of roses used in all the arrangements is 7r.

We know that each arrangement contains 9 tulips, so the total number of tulips used in all the arrangements is 7 * 9 = 63.

The total number of flowers used in all the arrangements is given as 147.

Therefore, we can write the equation:
7r + 63 = 147

To find the number of roses (r), we can solve this equation.

Subtracting 63 from both sides of the equation:
7r = 147 - 63
7r = 84

Dividing both sides of the equation by 7:
r = 84 / 7
r = 12

Hence, there are 12 roses in each flower arrangement.

Answer:

23.8

Step-by-step explanation:

In a right-angled triangle, x ² + b ² = c ²

30.5 is c, we can choose b to be 19.1.

x ² + b ² = c ²

x ² = c ² - b ²

= 30.5² - 19.1²

= 565.44

x = √565.44

= 23.8 (to 3 significant figures)

If the probability that an identified hurricane will make a direct hit on a certain stretch of beach is 1/4, what are the odds against a direct hit?

A)3 to 1
B)1 to 3
C)1 to 4

Answers

The odds against a direct hit is 3 to 1.

Given that the probability of a hurricane hitting at a coast is 1/4 = 0.25.

Therefore, the probability of not hitting = 1-0.25

= 0.75

we know that,

Odds against direct hit = [P(no direct hit)]/P[(direct hit)] = 0.75/0.25 = 3/1

= 3:1

Hence the odds against a direct hit is 3 to 1.

A cube has a depth of 9 dm. What is the volume of the cube?

Answers

The volume of the cube is 729 dm³

How to find the volume of the cube?

Remember that all the dimensions on a cube are the same ones, then we have:

Length = Width = Depth.

And for any prism, the volume is the product between the 3 dimensions, then for any cube the volume is:

V = Length*Width*Depth.

In this case we know that the depth is 9dm, then also is the length and the width, and thus, the volume of this cube is:

V = 9dm*9dm*9dm = 729 dm³

Answers

The volume of the quarter-sphere tank is approximately 1,387,244 cubic feet.

The volume of tank 1 is 353h cubic feet, and the volume of tank 2 is  31,416 cubic feet.

The main tank is in the shape of a quarter-sphere, which means it is a quarter of a full sphere.

The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius of the sphere.

Given that the radius of the main tank is 95 feet

we can substitute this value into the formula to calculate the volume:

V = (4/3)π(95³) = 1,387,244 cubic feet.

The holding tanks are in the shape of cylinders that have been cut in half vertically.

The volume of a cylinder is given by the formula V = πr²h, where r is the radius of the base and h is the height.

For tank 1, the radius is given as 15 feet. Since it is a half-cylinder, we divide the volume by 2:

V1 = (1/2)π(15²)h = 353h cubic feet.

For tank 2, the height is given as 120 feet.

V2 = (1/2)π(15²)(120) = 31,416 cubic feet.

The maximum density is 0.000021142 killer whales per cubic foot

we can calculate the maximum number of killer whales as follows:

Number of killer whales = (Volume of main show tank) / (Density of killer whales)

Number of killer whales = 1,387,244 / 0.000021142 ≈ 65,606,197.

Therefore, the maximum number of killer whales allowed in the main show tank at any given time is 65,606,197
