The number of files sorted in the first one and a half hours of sorting is 945.

Here, we are given that a group of clerks must sort 1775 files.

Each clerk sorts at a constant rate of 30 files per hour.

Let the number of clerks who start working initially be x.

Thus, they will sort 30x files in the first hour.

After the first hour, let the number of clerks who stop working be a

Thus, the number of files sorted in the second hour will be 30(x - a)

Similarly, the number of files sorted in the third hour will be 30(x - 2a)x

In the last 10 minutes, the number of files sorted will be 5(x - 3a)

Thus, we can form the following equation-

30x + 30(x - a) + 30(x - 2a) + 5(x - 3a) = 1775

30x + 30x - 30a + 30x - 60a + 5x - 15a = 1775

95x - 105a = 1775

19x - 21a = 355

x = (355 + 21a)/ 19

since x and a both have to be integers, (355 + 21a) must be divisible by 19.

This is the case when a = 3

⇒ x = (355 + 21*3)/ 19

x = 418/ 9

x = 22

Now, the number of files sorted in first one and a half hours will be-

30x + 15(x - a)

= 30*22 + 15(22 - 3)

= 660 + 15*19

= 660 + 285

= 945

Thus, the number of files sorted in the first one and a half hours of sorting is 945.

The probability that you win the game is 50%.

The game is symmetrical for you and your opponent. Thus, your probability of winning is as good as your opponent's, so, you have a 50% of winning.

Symmetry goes into play in probability theory in this way: if different outcomes are equivalent, they would have the same probability.

A symmetrical distribution happens when the values of variables come at regular frequencies and usually the mean, median, and mode all happen at the same point.

In general, if there are N symmetrical outcomes, the probability of any given one of them happening is taken to be 1/N.

Emma would need to invest about $320 to increase her value by $480 over the course of 8 years.

We may use the compound interest formula to determine how much Emma would need to invest:

[tex]\mathrm{A = P(1 + r/n)^{(nt)}}[/tex]

Where:

A is equal to the final sum, in this case $480.

P is the principal sum, which represents the initial investment that we're looking for.

r = the yearly interest rate (0.055 in decimal form, or 5.5%)

n = the number of times the interest is compounded annually (in this case, n = 1 because it is compounded annually).

t = the number of years, in this instance 8 years.

Let's substitute the known values into the formula and solve for P:

[tex]\mathrm{480 = P(1 + 0.055/1)^{(1\times8)}}[/tex]

Simplifying:

[tex]480 = \mathrm P(1.055)^8[/tex]

Dividing both sides by (1.055)⁸:

[tex]\mathrm {P = \frac{480 }{ (1.055)^8}}[/tex]

P ≈ $480 / 1.50

P ≈ $320

Hence the amount to be invested is $320.

The company is deploying chargeback type of IT funding model where the IT department charges her department for actual usage of a SharePoint server, determining how often users log in and how much storage space her department consumes.

Traditional IT and project finance methods offer a key business risk and, if not modified, jeopardize the future of technology-based enterprises.

This excerpt from the whitepaper Changing the Finance Method by Keanen Wold, Levi Geinert, Shaun Norris, Charles Betz, Beth Dumke, Sam Guckenheimer, and Troy Magennis discusses that contradiction over how traditional financing methods handle ethical concerns and also what Agile and DevOps teams require to execute successfully.

Balancing the high-risk investment in innovation (research and development department) with regular business-as-usual responsibilities has always been difficult for organizations. Too much risk might, in the case of an unexpected failure, result in a business's dissolution; too little innovation could ultimately cause the company to be overtaken and lose market share to rivals and new upstarts.

Given that the pay was $44,000 last year and $53,000 this year, the compensation will have increased by 20.45%.

In essence, percentages are fractions with a 100 as the denominator. We place the percent sign (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). Percentage is defined as "out of 100." Similar to fractions and decimals, percentages are used in mathematics to represent subsets of a whole. When expressing a sum as a percentage, 100 equal parts are considered to make up the whole.

Here,

Salary of staff last year=$44,000

Salary of staff this year=$53,000

The percent increase,

=(53000-44000)/44000*100

Hence, the value of y is 8.

Each of the three angles of the triangles whose sum of angles is 180 degree measures 75°, 65°, and 40°

An easy geometric instrument like a protractor is used to measure angles. A protractor is employed more frequently than a compass. Angle measurement is important for determining the precise angle. In geometry, there are several sorts of angles that we face in our daily lives, and we may measure angles using these tools.

Basic geometric instruments like a protractor and a compass are used to measure angles. These instruments aid in determining an angle's precise measurement. A protractor aids in producing an accurate angle measurement, while a compass aids in creating the angle. Angles can be measured in three different ways: in degrees, radians, and revolutions.

Here, we have

Let the largest angle be x degrees, the median y, and the smallest z.

x = 2y - 55

z = y - 25

x + y + z = 180

Substituting for x in the last equation:

2y - 55 + y + z = 180

3y + z = 235  

From the second equation:

- y + z = -25     Subtract this from the last equation:

4y = 260

y = 65 degrees

z = 65 - 25 = 40 degrees.

and x = 180 - 65 - 40 = 75 degrees.

The dimensions of the rectangle that will maximize the area of the window are length, L = 3.41 feet and width, w = 3.41 feet

Given: Perimeter (P) = 19 feet

Perimeter of window = Perimeter of rectangle + Perimeter of semicircle

P = 2(2r + L) + πr

where r = radius of the semicircle and   L = length of the rectangle

width(w) of the rectangle = 2r

Note: the diameter of the semicircle is the width of the rectangle

19 =  2(2r + L) + πr

19 = 4r + 2L + πr

2L = 19-4r-πr

L = 19/2 -2r- πr/2

Find the area (A) of the window:

A = Area of Rectangle + Area of Semicircle

A = 2rL + 1/2πr²

Put L into A = 2rL + 1/2πr²:

A = 2r(19/2 -2r- πr/2) + 1/2πr²

A = 19r - 4r² - πr² + 1/2πr²

A = 19r - 4r² - 1/2πr²

To maximize the area, differentiate both sides and set A' = 0

A = 19r - 4r² - 1/2πr²

A'  = 19 - 8r - πr

0  = 19 - 8r - πr

8r + πr = 19

r(8 + π) = 19

r = 25/(8 + π)

width(w) = 2r

w = 2[19/(8 + π)]

w = 38/(8 + π)

w = 3.41 feet

put r = 19/(8 + π) into L = 25/2 -2r- πr/2:

L = 19/2 -2(19/(8 + π))- π(19/(8 + π))/2

L = 19/2 - 38/(8 + π) - 19π/2(8 + π)

L = [19(8 + π) - 19(2)- 19π] / [2(8 + π)]

L = 38/(8 + π)

L =  3.41 feet

Therefore, the dimensions of the rectangle are length of 3.41 feet and width of 3.41 feet

Assuming the person's weight and magnitude, we can estimate their weight to be 491N.

A mathematical object's magnitude or size defines whether it is greater or smaller than other items of its kind.

In formal terms, an object's size can be thought of as the outward manifestation of an ordering—of the class of objects to which it belongs.

So, the person's weight will be:

The scale calculates the floor's usual upward force on the passenger.

The most force is produced when going up (when starting an upward trip or ending a downward trip).

The normal force is lowest when there is a downward acceleration.

Regarding any such situation

∑F y​ =ma y changes to +391Nmg = ma for halting and +591Nmg=+ma for starting. (Where a represents the size of the acceleration.)

Add these two simultaneous equations to eliminate a and determine mg:

+591N−mg+391N−mg=0

OR

982N–2mg=0

Fg​ = mg = 982N/2​ = 491N
