. At a given water/cement ratio, a change in the cement content or aggregate grading can be made to
increase the consistency of concrete. Why is it not desirable to produce concrete mixtures of a higher
consistency than necessary?

Answers

Answer 1

Answer:

It reduces strength.

Explanation:

It not desirable to produce concrete mixtures of a higher  consistency than normal because the strength of the concrete decreases. Consistency plays an important role in the determination of strength of concrete. Less water than normal quantity in concrete increases the consistency but decreases strength due to incomplete chemical reaction while on the other hand, adding more water would increase water-cement ratio and reduces consistency as well as  strength of the concrete so that's why necessary amount of water and cement should be added to get higher strength.

Swapping is a programming technique for changing the positions of two elements, letters, or objects. This is possible to use it on a list, a string, or an object. So, after swapping the value its calculated value is "200, 100", which is "Option A".

Swapping Program:

first=100#defining the variable first that holds an integer value

second=200#defining the variable first that holds an integer value

print("Before swapping the value: ")#print message

print(first)#print first value Before swapping

print(second)#print second value Before swapping

#performing the swapping operation

temp = first;#holdinig the first variable value in temp

first = second;#holdinig second variable value in first

second = temp;#holdinig temp value in second variable

print("After swapping the value: ")#print message

print(first)#print first value After swapping

print(second)#print second value After swapping

Output:

Please find the attached file.

Program Explanation:

Defining a variable first and second that holds an integer value that is "100 and 200".In the next step, a temp variable is used that performs the swapping into the given values and prints its values.

B. A limited liability company is subject to fewer regulations,
C. A limited liability company has an unlimited life span.
D. A limited liability company has access to more resources.
SUBMIT

Answers

Answer:B. A limited liability company is subject to fewer regulations.

Explanation:

A. P. E. X

One benefit of a limited liability company over a corporation is a limited liability company offers less risk to its owners. Therefore, the correct option is option A.

One advantage of a limited liability company (LLC) over a corporation is that it exposes its owners to less risk. The owners, known as members, of an LLC have limited liability protection. This means that the members' personal assets are normally safeguarded from the LLC's obligations and liabilities. If the LLC encounters financial difficulties or legal claims, the members' personal assets are protected, and their risk is limited to the amount invested in the firm.

In contrast, stockholders in a corporation might be held personally accountable for the company's debts and legal obligations, especially if there is no clear separation of personal and corporate assets. This increases the danger to the shareholders' personal assets.

Answers

I'm guessing you're writing an SAQ.  I can't write it for you, but here are some ideas.

A) You can write about how industrialization had led to mass immigration to cities to fill factory positions, which directly led to the creation of a large working class population and the development of the wealthy middle class.  You can also talk about how Karl Marx called these classes the proletariat and the bourgeoisie.

B) You can perhaps say that lack of union representation made it very difficult for workers to voice their issues and concerns on multiple topics like low wages and working conditions.  This made it difficult to get their voices heard, so they were not able to get the resources or pay they needed to move about society.

C) Communism/Marxism is the easiest one to go with.  It should be very easy to talk about how Marx saw the industrial revolution as reinforcing the idea of class struggles throughout history and how he believed the bourgeoisie were oppressing the working-class proletariat with the only solution being a violent revolution and "dictatorship of the proletariat".  Mention the Communist Manifesto.

Kaitlyn is walking on a treadmill at a constant pace for 28 minutes. She has programmed the treadmill for a 2-mile walk. The display counts backward to show the distance remaining. Enter and graph the equation that gives the distance f(x) left in miles as a function of the number x of minutes she has been walking. Then, find and compete the interpretation of the x- and y-intercepts.

Answers

Answer:

Explanation:

slope is constant at 2/28 = -1/14; negative cuz' its counting down

x-intercept is at x=28 when walk ends

y-intercept is at y=2 when walk starts

so f(x) is y=2-x/14

see graph attached

Answer:

Explanation:

Kaitlyn walked at a constant pace for 28 minutes and finished a 2-mile walk.  She has programmed the treadmill for a 2-mile walk.

Let  the distance left in miles as function f(x) and x as the number of minutes she has been walking.

At x=0, the y-intercept, f(x) is 2 miles as it is at the very beginning of walk.

At y=0, the x-intercept, x is 28 minutes as it is at the very end of walk.

Her pace is constant at 14 minutes per mile.

Using the above info, f(x) can be set up as a linear x-y function of:

y =  -x/14 + 2
