According to the given time card the pay for the day is $96.25.

To calculate the pay for a day, we need to determine the total number of hours worked for that day. We can do this by subtracting the start time from the end time for each shift.

In the morning, the start time is 8:00 and the end time is 12:00, so the number of hours worked is 12:00 - 8:00 = 4 hours.

In the afternoon, the start time is 12:45 and the end time is 17:30, so the number of hours worked is 17:30 - 12:45 = 4 hours and 45 minutes, which we can convert to decimal form by dividing 45 by 60 to get 0.75 hours.

The total number of hours worked is 4 + 4.75 = 8.75 hours.

Since the wage is $11/hr, the pay for the day is 8.75 hours * $11/hr = $96.25.

Rounding to the nearest hundredth, the pay for the day is $96.25.

Answer:

No.C 5 is the correct answer

Answer:

c is the correct answer..

During Week 0, the number of specialty items that were produced at the old factory than at the new factory is 46 specialty items.

The growth rate for the old factory is 0.08 or 8%.

The weekly number of specialty items produced at the new factory would exceed the weekly number of specialty items produced at the old factory from the 5th week.

Mathematically, an equation which can be used to model an exponential growth rate is given by this mathematical expression:

A(t) = P(1 + r)^{t}    ......equation 1.

Where:

Based on the information provided, an exponential function that represents the number of specialty items that are produced at the old factory is given by:

P(w) = 236(1.08)^w     .......equation 2.

When week, w = 0, the number of specialty items that were produced at the old factory is:

P(0) = 236(1.08)^0

P(0) = 236 specialty items.

For the new factory, the number of specialty items is equal to the y-intercept of the given graph, which is equal to 190 specialty items.

Therefore, the difference = 236 - 190 = 46 specialty items.

For the growth rate for the old factory, we would compare equation 1 and equation 2 as follows:

1 + r = 1.08

Growth rate, r = 1.08 - 1

Growth rate, r = 0.08 or 8%.

Next, we would determine the exponential function that represents the new factory:

505 = 190(1 + r)^7

505/190 = (1 + r)^7

Growth rate, r = (505/190)^{1/7} - 1

Growth rate, r = 1.1499 - 1,

Growth rate, r = 0.1499 ≈ 0.15 or 15%.

Therefore, the function is given by q(w) = 190(1.15)^w.

When the weekly number of specialty items produced at the new factory exceed the weekly number of specialty items produced at the old factory, we have:

190(1.15)^w > 236(1.08)^w

(1.15)^w/(1.08)^w > 236/190

1.0648^w > 1.2421

Taking the ln of both sides, we have:

w > ln(1.2421)/ln(1.0648)

w > 4.3

This fraction can be simplified to its lowest terms, which is 8/15.

In mathematics, a fraction is in its lowest terms when its numerator and denominator cannot be divided by any other number than one. This means that the numerator and denominator of the fraction do not share any common factors, except one. To convert a fraction to its lowest terms, divide the numerator and denominator by any common factors they may have.

To solve this problem, we need to first convert both fractions to have the same denominator. To do this,

we can multiply the denominator of 4/9 by 5/5,

which is equal to 20/45.

Then, we can multiply the denominator of 6/15 by 3/3,

which is equal to 18/45.

Now that both denominators are the same,

we can add the numerators together to get a sum of 8/15.

This fraction can be simplified to its lowest terms,

which is 8/15.

Answer:
it took Sean 3 hours to write the essay.

Step-by-step explanation:

We know that the ratio of time Sean spent writing the essay to the time he spent revising the essay was 4:1, which means that for every 4 units of time he spent writing the essay, he spent 1 unit of time revising it.

Let's call the time he spent writing the essay "x" and the time he spent revising the essay "y". We know that x + y = 15 (because he spent a total time of 15 hours writing and revising the essay) and that the ratio of x to y is 4:1, so 4x = y.

We can substitute the second equation into the first equation:

x + 4x = 15

5x = 15

x = 3

So it took Sean 3 hours to write the essay.

Answer:

Step-by-step explanation:

Labor rate: $60/hr

Labor time: 0.3hr

Labor cost= 60*0.3=$18

Battery cost= $69.95

Tax=5%

Total battery cost is 69.95*1.05= 73.4475≈$73.45

Total cost= $73.45+$18= $91.45

The total bill with 6 percent of tax is $36.87, for which the server must be paid one $20 bill, one $10 bill, one $5 bill, one $1 bill and 0.87 pennies.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred.

The amount for total bill is $34.78.

The sales tax percentage added is 6%.

The total bill including tax will be -

Final Bill = Total Bill + (Total Bill × tax)

Substitute the values into the equation -

Final Bill = 34.78 + (34.78 × 6%)

Final Bill = 34.78 + (34.78 × 0.06)

Final Bill = 34.78 + 2.0868

Final Bill = 36.8668 ≈ 36.87

Therefore, the final bill is $36.87.

The amount of $20 bill = 1

The amount of $10 bills = 2

The amount of $5 bills = 1

The amount of $1 bills = 5

The amount of pennies = x

So, the amount of bill given to server to make a total of $36.87 is -

1 × ($20) + 1 × ($10) + 1 × ($5) + 1 × ($1) + x = $36.87

20 + 10 + 5 + 1 + x = 36.87

36 + x = 36.87

x = 36.87 - 36

x = 0.87

Therefore, along with 1 bill each 0.87 pennies should be given to the server.

The answer to the query is that $14.28 is left on your credit throughout 44 minutes of calls.

When any term's greatest degree is two or higher, an equation is said to be nonlinear. This is a sample of a numerical solution since formula has the highest degree of 2, whereas equation 2 includes the variables x and y. 3x + 4y = 5, etc., where + 2x + 1 = 0.

Let y be the remaining credit (in dollars) and x be the calling time (in minutes). Based on the information given, we have two points on the line: (24, 16.88) and (38, 15.06).

Using these two points, we can find the equation of the line using the point-slope form:

y - 16.88 = m(x - 24)

where m is the slope of the line. Substitute one of the points to find m:

15.06 - 16.88 = m(38 - 24)

-1.82 = m(14)

m = -1.82/14 = -0.13

Now we have the slope of the line, we can write the equation of the line using the point-slope form:

y - 16.88 = -0.13(x - 24)

To find the remaining credit after 44 minutes, substitute x = 44 into the equation:

y = -0.13(44 - 24) + 16.88

y = -0.13(20) + 16.88

y = 16.88 - 2.6

y = 14.28

So the remaining credit after 44 minutes of calls is $14.28.

To fit the mascot's digital image on the school's Web page, it needs to be resized. To determine the largest image that will fit, we need to find the aspect ratio of the Web page and the aspect ratio of the digital image and keep the aspect ratio the same after resizing.

How is the ratio defined?

A ratio depicts the quantity of one object in relation to another. Ordinarily, ratios are expressed in the format a:b. If you're preparing orange squash, the ratio of orange to water will be one part orange to four parts water (1 to 4).

The aspect ratio of the Web page is 176 pixels wide / 110 pixels high = 1.6.

The aspect ratio of the digital image is 600 pixels wide / 375 pixels high = 1.6.

Since both aspect ratios are the same, we can simply choose the smaller dimension from the Web page (110 pixels) to determine the size of the resized image.

So, the resized image will be 110 pixels high and the width will be 110 pixels * 1.6 aspect ratio = 176 pixels.

Therefore, the largest image of the mascot that will fit on the Web page is 176 pixels wide by 110 pixels high.

Random sampling is a method of selecting a sample of items from a population in which the probabilities of selecting each item are the same.

Random sampling is used to ensure that each item in the population has an equal opportunity to be selected in the sample.

In this scenario, a random sample of size 40 is needed from a population of 200 items. The random start of 4 will be used to begin the sample selection process.

To begin, a list of all the items in the population should be created. Then, a random number generator can be used to select the first item in the sample, based on the random start of 4.

The next item in the sample should be selected at random from the remaining items in the population, and so on until the desired sample of 40 items is obtained.

Random sampling is an important method for ensuring that a sample is representative of the population it is drawn from.

This method helps to eliminate bias from the sample selection process and ensures that the sample accurately reflects the characteristics of the population.

Random sampling is used in many areas of research, including surveys, data collection, and experiments.

A security is a financial instrument, generally any financial asset that can be traded. The nature of what is and is not considered a security generally depends on the jurisdiction in which the asset is traded. Securities are transferable financial instruments issued by companies or governments that convey ownership, debt obligations, or the right to buy, sell, or trade options.

It may represent a company represented by an ownership interest in the company in the form of shares, a creditor relationship with a government agency, or an ownership interest in the bonds of that agency or property rights represented by options.

Debt or fixed income securities represent loans that must be repaid on terms that indicate the amount borrowed, interest rate, and maturity date. In other words, a debenture is an instrument of debt such as a bond or a certificate of deposit (CD) that can be traded between parties. Debt securities, such as bonds and certificates of deposit, typically require the owner to make periodic interest payments, repay principal, and other contractual rights. Such securities are typically issued for a period of time and eventually repaid by the issuer.
