Answer: 20.87/21 minutes

Step-by-step explanation: 1858/2 = 20.8764044944

                                             2 x 20.8764044944 = 1858

It takes approximately 21 minutes for the copier to print 1,858 copies, given that the copier prints at a rate of 89 copies per minute.

To determine how long it takes for the copier to print 1,858 copies, we can set up a proportion since we know the rate at which the copier prints is 89 copies per minute. We calculate the time it would take by dividing the total number of copies needed by the number of copies the machine can print per minute:

Time (in minutes) = Total Copies ÷ Rate

Time (in minutes) = 1,858 copies ÷ 89 copies per minute

After performing the division, we find that:

Time (in minutes) = 20.8764 minutes

Since we generally measure time in whole minutes when it comes to using office equipment, we can round this to the nearest whole number, thus giving us approximately 21 minutes to complete the printing task.

The new formula for B6 cell will be B6=A6*2

Answer:

B6 =A6*2

Step-by-step explanation:

In Excel, the rectangular box where the rows and column intersect is called cell. The raws are represented by  1, 2, 3, 4, ................, the columns are represented by A, B, C, D,........,The notation of a cell is 'column row',

When we fill a formula in a cell then it can be proceed in below cells.

Here, the given formula,

B5=A5*2

Since, B6 is the below cell of the cell B5,

And, A6 is the below cell of the cell A5,

Thus, the new formula would be,

B6 =A6*2

Hi the answer is d 40 i hope this helps,

4+4 is 8

8+8 is 16

12+16 is 24

So 16+24 is 40

The answer is C. 32. As you can see, the first variable is multiplied by the second variable of the table. Thus, you would have to multiply 8 and 4. Which would give you the answer of 32.

So that would be the same thing as 5 4/5 - 3 2/7

Put them in mixed fractions to become 29/5 - 23/7

Multiply one side by 7 and one side by 5 to get the same denominator  

203/35 - 115/35

Now subtract the numerators to get

88/35

Or if they want it inixed numbers then 2 18/35

54/5 - 32/ 7

=(378 -160)/ 35

=218/35

answer: $94.12

work:

let's start by finding the tax.

step one: convert the percentage into a decimal by dividing it by 100.

4 / 100 = 0.04

next, multiply your total by the tax

$90.5 x 0.04 = 3.62.

next, add the tax to the original price to see your new total.

$90.5 + $3.62 = $94.12

so, your total with tax would be $94.12.

50-500=450

450/15=30

30 weeks

Albert needs 30 weeks to save $500, starting with an initial $50 and depositing $15 each week after.

The subject of this problem is saving money over time. Albert starts with an initial amount of $50. Each week afterward, he adds an additional $15 to his savings. If he wants to save a total of $500, we need to figure out how many weeks that will take.

Since Albert already starts with $50, we first subtract that from $500, the total he wants to save, which leaves $450.

Then, we divide 450 by the amount Albert saves each week, $15. This equals 30, meaning it will take Albert 30 weeks to save $500.

The values of data that may affect the statistical measures of center and spread are the outliers and extreme values in the female dataset.

Statistical measures of center include the mean, median, and mode, while measures of spread include the range, interquartile range (IQR), variance, and standard deviation.

 From the given box plots:

 For males:

- The minimum number of hours worked per week is approximately 15.

- The first quartile (Q1) is approximately 20.

- The median (Q2) is approximately 22.

- The third quartile (Q3) is approximately 25.

- The maximum number of hours worked per week is approximately 35.

 For females:

- The minimum number of hours worked per week is 0.

- The first quartile (Q1) is approximately 0.

- The median (Q2) is approximately 20.

- The third quartile (Q3) is approximately 25.

- The maximum number of hours worked per week is approximately 50.

In the male dataset, there are no apparent outliers or extreme values since the data is relatively compact with a narrow IQR and no data points far from the quartiles.

However, in the female dataset, there are potential outliers or extreme values:

- The minimum value of 0 hours worked per week is an outlier because it is far below the first quartile.

- The maximum value of approximately 50 hours worked per week is an extreme value because it is far above the third quartile.

These outliers and extreme values in the female dataset can significantly affect the measures of center and spread:

- The mean will be pulled down by the minimum value of 0 and up by the maximum value of 50, potentially making it less representative of the central tendency of the data.

- The range will be much larger due to the extreme maximum value.

- The IQR will not be affected by these outliers since it is based on the middle 50% of the data, but the overall spread of the data will be larger due to the presence of outliers.

- The variance and standard deviation will be increased by the presence of these outliers, indicating a larger spread in the data.

 In summary, the outliers and extreme values in the female dataset are the values that may affect the statistical measures of center and spread. These values can skew the mean, increase the variance and standard deviation, and extend the range, making these measures less indicative of the typical work hours for female students.

Answer:

False

Step-by-step explanation:

y=0.5(x−1)

Hope i helped

y=2x+1, replace x by y and vice versa

x=2y+1 now solve for y

y=0.5(x-1)

Lets set up an equation to easier understand this.

1/1.5 = 3.7/x   (x represents the unknown km)

We know that whatever you do to the top you do to the bottom.

And we can see that 1 x 1.5 = 1.5

So we can multiply the same thing by 3.7

1.5 x 3.7 = 5.55

So in this case you would travel 5.55 km in 3.7 seconds.

Answer:

Option D

the weights would be the best deal is [tex]2\frac{7}{8}[/tex]

Step-by-step explanation:

The price of all meat packages are marked $12.99.

To find the best deal we have to show that the weight of which  package will be greatest.

The weight of each packages are written as a mixed fraction as follows;

[tex]2\frac{2}{3} , 2\frac{9}{11} , 2\frac{4}{5} , 2\frac{7}{8}[/tex]

Now, convert these improper fraction into proper fraction.

[tex]2\frac{2}{3}=\frac{8}{3}[/tex]

[tex]2\frac{9}{11}=\frac{31}{11}[/tex]

[tex]2\frac{4}{5}=\frac{24}{5}[/tex]

[tex]2\frac{7}{8}=\frac{23}{8}[/tex]

To make their denominators same,

the LCM(Least common multiples) of the denominators(11, 3, 5, 8) is 1320.

So,

[tex]\frac{8}{3}= \frac{8\cdot 440}{3\cdot 440} =\frac{3520}{1320}[/tex]

[tex]\frac{31}{11}= \frac{31\cdot 120}{11\cdot 120} =\frac{3720}{1320}[/tex]

[tex]\frac{14}{5} =\frac{14\cdot 264}{5\cdot 264}= \frac{3696}{1320}[/tex]

[tex]\frac{23}{8}=\frac{23\cdot 165}{8\cdot 165} =\frac{3795}{1320}[/tex]

As, you can see that the only fraction is greatest is [tex]\frac{3795}{1320}[/tex]

therefore, the weight [tex]2\frac{7}{8}[/tex] would be the best deal.

Cold Farms:

Small box

1 pint = $2.50

1 quart = $4.50

Large Box

1 quart = 2 pints .

2 pints  = $4.50

1 pint = $4.50 / 2 = $2.25

Cone Dreams:

Small box

1 quart = $4.25 and

1 pint = $4.25/2 =  $ 2.125

Large Box

1 gallon = $9.50.

1 gallon = 8 pints

8 pints = $9.50.

1 pint = $9.50 / 8 = $ 1.1875.

Answer:

The larger size of the cold farm ice cream is the better deal . To get the equivalent volume of the small size to the large size , one needs to spend $2.5 + $2.5 = $5.0 where as for the larger size you will only spend $ 4.5.

Step-by-step explanation:

The price for cold farm ice cream for the small size is $2.5 for 1 pint and for the larger size it is $4.5 for 1 quarts. Sheldon wants to know the better deal for the size container of cold farm ice cream.

Firstly, the prices are in different volume unit we need to convert them to the same units.

1 pints = 0.5 quarts

That means small size of cold farm ice cream is $ 2.5 for 0.5 quart and larger size is $ 4.5 for 1 quart.

Small size  

$2.5 for 0.5 quart

$5.0 for 1 quart

Larger size  

$ 4.5 for 1 quart

The larger size of the cold farm ice cream is the better deal . To get the equivalent volume of larger size , one needs to spend $2.5 + $2.5 = $5.0 where as for the larger size you will only spend $ 4.5.

Be very careful that you leave the open end of the less than symbol pointing towards the x It means that x is greater than 8.

You could write it the other way x > 8 but the pointy end must always be closest to the 7 which is another way of saying what the answer means.

Answer:

Angie will need to save $2.50 for 8 more weeks to get $50

Step-by-step explanation:

Angie has already saved $30

12(2.5)=30

So since she needs $20 more you divide 20 by 2.5 and you get your answer.

20/2.5=8 weeks

Angie has saved $2.50 per week for the past 12 weeks, so she has saved a total of 2.50*12 = $30.00. To reach her goal of $50.00, she needs to save another 50-30 = $20.00. At her current rate of saving, it will take her 20/2.5 = 8 more weeks to reach her goal.

To calculate the total amount of money Angie has saved so far, we simply multiply the amount of money she saves each week by the number of weeks she has been saving.

In this case, Angie saves $2.50 per week and she has been saving for 12 weeks, so she has saved a total of $2.50 per week x 12 weeks = $30.

To calculate the amount of money Angie still needs to save, we simply subtract the amount of money she has saved so far from her goal amount.

In this case, Angie's goal amount is $50 and she has saved $30 so far, so she still needs to save $50 - $30 = $20.

To find out how many more weeks it will take Angie to reach her goal, we simply divide the amount of money she still needs to save by the amount of money she saves each week.

In this case, Angie still needs to save $20 and she saves $2.50 per week, so it will take her $20 / $2.50 per week = 8 weeks to reach her goal.

Therefore, it will take Angie 8 more weeks to save a total of $50.
