Answers

Answer 1

The Big Island of Hawaii will take approximately 0.243 years or 2.92 months to reach the subduction zone off Japan if the "Pacific Plate Express" operates without change.

Given, the following table of the islands: Name of Island Kure Midway Necker Kauai Distance from Kilauea (km) 2600 2550 1000 600 Age 31 25 12 5 3To calculate:

(A) The average rate of plate motion since Kure Island formed in cm/yr. The distance between Kure Island and Kilauea = 2600 km The age of Kure Island = 31 myr=31×106 yearsDistance = Speed × Time Thus, the average rate of plate motion since Kure Island formed = Distance / Time= 2600000000 cm / (31×106 years)= 84.516 cm/yr Thus, the average rate of plate motion since Kure Island formed in cm/yr is 84.516 cm/yr.

(B) The average rate of plate motion since Kauai formed in cm/yr. The distance between Kauai and Kilauea = 600 km The age of Kauai = 5 m yr=5×106 years Distance = Speed × Time Thus, the average rate of plate motion since Kauai formed = Distance / Time= 60000000 cm / (5×106 years)= 12 cm/yr Thus, the average rate of plate motion since Kauai formed in cm/yr is 12 cm/yr.

(C) The Pacific plate was moving at an average rate of 84.516 cm/yr since Kure Island formed and at an average rate of 12 cm/yr since Kauai formed. The Pacific plate has been moving slower during the last 5 my as compared to the last 26 my since it was moving at an average rate of 84.516 cm/yr over the last 26 m.y. and at an average rate of 12 cm/yr over the last 5 my.

(D) The total average rate since Kure Island formed = 84.516 cm/yrIn 1 year, the plate moves a distance of 84.516 cm In 50 years, the plate moves a distance of 84.516 × 50= 4225.8 cm or 42.258 m Thus, the Pacific Plate will move 42.258 m in 50 years using the total average rate since Kure Island formed.

(E) The trajectory of the Pacific Plate currently points towards Japan, approx. 6500 km away. Distance between Japan and Hawaii = 6500 km Distance traveled in 1 year at an average rate of 84.516 cm/yr = 84.516 × 365×24×60×60 cm= 2.67 × 1012 cm= 26700000 m Thus, the time taken to travel a distance of 6500 km= 6500000 m / 26700000 m/yr= 0.243 years

The product of 6 and the square of a number

Consider the number as x

Then the product of 6 and the square of a number = \(6x^2\)

The product of 6 and the square of a number is increased by 5 times the number, the result is 4

Then the equation will be

\(6x^2\) + 5x = 4

Move 4 to the left hand side of the equation

\(6x^2\) + 5x - 4 = 0

We have to solve the quadratic equation

Split the middle terms

\(6x^2\) + 8x - 3x -4 = 0

2x(3x+4) -1(3x+4) = 0

(2x-1)(3x+4)= 0

Then the value of x will be

2x- 1 = 0

2x = 1

x = 1/2

Similarly

3x+4 = 0

3x = -4

x = -4/3

An average of 26 clients come in a Poisson process to a car repair shop in a 12 hour workday. 80% of them need an oil change that takes exactly half an hour. One mechanic is doing all the oil changes. The rest of the clients come for a major repair that takes an average of 6 hours and is exponentially distributed. There are 4 mechanics doing these repairs. Enter the answers in the MMk tab.
a. How many hours it takes from the moment a car comes for an oil change until they can pick it up?
b. How many hours it takes from the moment a car comes for a major repair until they can pick it up?
c. How many cars are expected to be in the shop at any giventime?

Answers

A) On average, it takes 0.5 hours (30 minutes) from the moment a car comes for an oil change until they can pick it up.

B) On average, it takes 6.75 hours from the moment a car comes for a major repair until they can pick it up.

C) The expected number of cars in the shop at any given time is 10.44.

How long does it take from a car's arrival for an oil change until it can be picked up?

On average, it takes 0.5 hours (30 minutes) from the moment a car comes for an oil change until they can pick it up. This includes the time spent by the mechanic performing the oil change. The Poisson process with an average arrival rate of 26 clients in a 12-hour workday allows us to estimate this waiting time. Efficiently completing oil changes in a timely manner is crucial for customer satisfaction and the smooth operation of the car repair shop.

On average, it takes 6.75 hours from the moment a car comes for a major repair until they can pick it up. This accounts for the time spent by the four mechanics working on major repairs, which follows an exponential distribution with an average repair time of 6 hours. Understanding the average waiting time for major repairs helps the car repair shop manage customer expectations and plan their resources effectively.

The expected number of cars in the shop at any given time is 10.44. This takes into account the arrival rate of clients for oil changes and major repairs, as well as the average service times for each type of service. The MMk queuing model allows us to estimate the expected number of cars in the system. This information helps the car repair shop allocate sufficient resources, such as mechanics and workstations, to ensure smooth operations and minimize customer wait times.

The ratio of corresponding sides for the given similar triangles is 2/5.

In the given options, the ratio of corresponding sides is provided for each set of similar triangles. Let's analyze each option to determine the correct ratio:

a. 10

This option only provides a single number and does not specify the ratio of corresponding sides. Therefore, it is not the correct answer.

b. 4/5

This option provides the ratio 4/5 for the corresponding sides of the similar triangles. However, the ratio can be simplified further.

To simplify the ratio, we divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 4 and 5 is 1.

Dividing 4 and 5 by 1, we get:

4 ÷ 1 = 4

5 ÷ 1 = 5

Therefore, the simplified ratio is 4/5.

c. 10/85

This option provides the ratio 10/85 for the corresponding sides of the similar triangles. However, this ratio cannot be simplified further, as 10 and 85 do not have a common factor other than 1.

Therefore, the correct ratio of corresponding sides for the given similar triangles is 2/5, as determined in option b.

Answers

The recommended rule to sequence the jobs for minimum flow time is the EDD (Earliest Due Date) rule.

The EDD rule prioritizes jobs based on their due dates, where jobs with earlier due dates are given higher priority. By sequencing the jobs in order of their due dates, the goal is to minimize the total flow time, which is the sum of the time it takes to complete each job.

In this case, applying the EDD rule, the sequence of jobs would be as follows:

D (Due on Friday 10th June)

F (Due on Tuesday 14th June)

E (Due on Wednesday 15th June)

C (Due on Friday 17th June)

G (Due on Thursday 16th June)

H (Due on Saturday 18th June)

A (Due on Monday 13th June)

B (Due on Monday 20th June)

By following the EDD rule, we aim to complete the jobs with earlier due dates first, minimizing the flow time and ensuring timely delivery of the orders.

Therefore, the recommended rule for sequencing the jobs in this scenario is the EDD (Earliest Due Date) rule.

-2 * 3 + -2 * 7h + 2 = 108

combine like terms

-6 - 14h + 2 = 108

-4 - 14h = 108

add 4 to both sides of the equation

-4 + 4 - 14h = 108 + 4

-14h = 108 + 4

-14h = 112

Answers

A pencil consists of a cylindrical body (10 cm long, radius 0.3 cm) with a cone-shaped eraser (1 cm slant height) and a hemisphere-shaped eraser.

A pencil consists of three main parts: a cylindrical body, a cone-shaped eraser, and a hemisphere-shaped eraser. Let's break down the dimensions of each part:

Cylindrical Body:

Length: 10 cm

Radius: 0.3 cm

Cone-shaped Eraser:

Slant height: 1 cm (assumed height of the cone)

Hemisphere-shaped Eraser:

Since the dimensions of the hemisphere-shaped eraser are not specified in detail, we'll assume a few things:

Let's assume that the hemisphere is attached to the cone in such a way that the flat surface of the hemisphere is aligned with the circular base of the cone.

We'll assume that the radius of the hemisphere is the same as the radius of the cylindrical body, which is 0.3 cm.

Please note that the actual dimensions of a pencil can vary, and these assumptions are made for the purpose of explanation.

It's worth mentioning that the cylindrical body of the pencil is the main part used for writing, while the cone-shaped and hemisphere-shaped erasers are located at the opposite end of the pencil, typically used for erasing mistakes.

I bought a lawnmower that cost $479 dollars. I also had to pay 5% sales tax. How much tax did I have to pay? And how much did I pay in total

Answers

Answer:

Tax: $23.95

Total: $502.95

Explanation:

The tax that you have to pay is equal to 5% of $479. So, we can calculate the tax as follows:

\(479\cdot5\text{ \% = 479}\cdot\frac{5}{100}=23.95\)

So, you need to pay $23.95 for tax.

Then, in total, you pay the initial cost plus the sales tax, so:

$479 + $23.95 = $502.95

Therefore, the answers are $23.95 for tax and $502.95 in total.

Rs. 85000 was exempted in the yearly income of a government service holder. If he paid tax Rs. 8850 in a year at the rate of 15%. What was his monthly income?​

Answers

The monthly income of the government service holder is Rs. 12000

How to determine the monthly income?​

A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation

Given that: Rs. 85000 was exempted in the yearly income of a government service holder. If he paid tax Rs. 8850 in a year at the rate of 15%.

Let P represent the yearly income. We can write that:

15% (P - 85000) = 8850

0.15(P - 85000) = 8850

0.15P - 12750 = 8850

0.15P = 8850 + 12750

0.15P = 21600

P = 21600/0.15

P = 144000

So the yearly income is  Rs. 144000

Thus, the monthly income will be:

Rs. 144000 / 12 = Rs. 12000

What are the vertical and horizontal asymptotes of F x )= 3x 2 x 2 4?

Answers

As given by the question , so here the vertical and horizontal asymptotes are at x = -12 and y = 1.5.

What is vertical asymptote?

On a function graph, a vertical asymptote represents the point at which the function is undefined. Take the formula f(x) = 1/x as an illustration. This function's graph exhibits a vertical asymptote at x = 0 since the function is undefined at this value (division by 0 is undefined).

What is horizontal asymptote?

A function's horizontal asymptote is a horizontal line on the function graph that the function approaches as the input (x-value) increases or decreases dramatically. Consider the function f(x) = x2 as an illustration. Because the y-values of the function do not converge to a fixed value as x grows very big, the graph of this function lacks a horizontal asymptote.

We must identify the values of x at which the function is undefined in order to determine the vertical asymptotes of the function 3x/(2x+24).So, to find the vertical asymptotes of the function, we need to solve the equation 2x + 24 = 0 for x. so x = -12.

Similarly, To find the horizontal asymptote in case of equal degrees of numerator and denominator i.e 1 in this case, we need to take the ratio of the first coefficients of numerator and denominator respectively which is 3/2 = 1.5.

These are the corresponding points for the inverse function.

So, the points that lie in the inverse of the graph of g(x) are:

(-1, 0.5), (0, 1), (1, 2), (2, 4), (3, 8).

Hence the correct points are (1, 2) and (0,1).

Answers

The solution is (-1, 1). The solution has been obtained using linear equations.

What is a linear equation?

The linear equation with the highest degree of one is this one. This implies that there are no variables in a linear equation with exponent greater than 1. This equation results in the graph having a straight line.

In order to obtain the solution, we will see which point satisfies both the equations.

1. (1,1)

⇒x-2y = -3

⇒1-2 = -3

⇒-1 ≠ -3

So, this is not the solution.

2. (1, -1)

⇒x-2y = -3

⇒1-2(-1) = -3

⇒1+2 = -3

⇒3 ≠ -3

So, this is not the solution.

3. (-1, 1)

⇒x-2y = -3

⇒-1-2 = -3

-3 = -3

Second equation

⇒y = -2x - 1

⇒1 = -2(-1) - 1

⇒1 = 2 - 1

1 = 1

Thus, this is the solution.

Hence, the solution is (-1, 1).

f scores are normally distributed with a mean of 35 and a standard deviation of 10, what percent of the scores is: (a) greater than 34?

Answers

The percentage of scores greater than 34 is 0.5398 or 53.98%.

Given that the mean of scores (μ) = 35 and the standard deviation (σ) = 10. We need to find the percentage of scores greater than 34. Since the scores are normally distributed, we can standardize the variable by using the z-score formula.

z = (x - μ) / σ

Here, x = 34, μ = 35 and σ = 10z = (34 - 35) / 10z = -0.1

We need to find the area to the right of the z-score line on the standard normal distribution table. The standard normal distribution table provides the probabilities corresponding to the z-scores, i.e. the area under the curve to the right or left of the z-score line on the distribution table. The area to the right of the z-score line represents the percentage of scores that are greater than the given value. Using the standard normal distribution table, the area to the right of the z-score line -0.1 is 0.5398.

The percentage of scores greater than 34 is 0.5398 or 53.98%.

One gallon of floor paint costs \$21.99$21.99 and can cover a 2020​-​foot by 2020​-foot floor. How much would the floor paint cost to paint a 140140​-foot by 140140​-foot floor?​

Answers

The total cost to cover the floor is $1,077.51

How much will cost to cover a 140ft by 140ft floor?

Here we know that one gallon of floor paint costs $21.99 and covers an area of 20ft by 20ft

That area is 20ft*20ft = 400ft^2

Now, for the floor of 140ft by 140ft the area is:

A = 140ft*140ft = 19,600ft^2

We need to see how many times 400ft^2 are in 19,600ft^2, so we take the quotient:

19,600ft^2/400ft^2  = 49

That is the number of gallons of paint that we will need, then the total cost is:

C = 49*$21.99 = $1,077.51
