It takes, 2, minutes to prepare one bag. If Ashley works alone, it will take her 900 bags× 2 minutes each =1800 minutes to prepare the bags.
Since there are 60 minutes in an hour, that's the same as 1800/60 which equals to 30 hours. If there are 6 people sharing Ashley's work Ashley + 5 friends the work will be finished 6 times as fast.
A team of 6 people can finish the job 30/6 which equals 5

Jeremy surveyed students in his class about their spending habits in the school cafeteria. He used the data to create a scatterplot.
How Students Spend Money in the Cafeteria
Which is the equation of his trend line?
y= 2.75x
y= 3.05x- 0.6
y= 3.25x- 1
y= 9.75x- 14
Answer:
[tex]y=3.25x-1[/tex]
Step-by-step explanation:
step 1
Find the slope
we have the points
(2,5.5) and (5,15.25)
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
substitute
[tex]m=\frac{15.25-5.5}{5-2}[/tex]
[tex]m=\frac{9.75}{3}=3.25[/tex]
step 2
Find the equation of the line in slope intercept form
y=mx+b
we have
[tex]m=3.25\\point\ (2,5.5)[/tex]
substitute
[tex]5.5=3.25(2)+b[/tex]
solve for b
[tex]b=-6.5+5.5=-1[/tex]
therefore
[tex]y=3.25x-1[/tex]

What is the slope of the line of best-fit in the scatterplot below?
9/27
3/7
7/3
27/9
Answer:
Option C is correct
7/3
Step-by-step explanation:
Formula for slope is given by':
[tex]\text{Slope} = \frac{y_2-y_1}{x_2-x_1}[/tex] ....[1]
As per the statement:
The graph shows the best fit line scatter-plot.
Consider two points i.e
(3,12) and (6, 19)
Substitute these points in [1] we have;
[tex]\text{Slope} = \frac{19-12}{6-3}[/tex]
⇒[tex]\text{Slope} = \frac{7}{3}[/tex]
Therefore, the slope of the line of best-fit in the scatter plot is, 7/3

Frank’s electric bill has a cycle day of the 3rd and a due date 8 days later with a one day grace period. What happens if Frank pays his electric bill on the 12th of the month?
Frank’s electric bill has a cycle day of the 3rd
And the due date of the bill is 8 days later
that is 3+8 = 11th of that month is the due date
The bill is to be paid by 11th
But 1 day grace period is given
So
11+1
=12
If one pays the bill by 12th of that month , then no penalty will be imposed.
And
Frank pays his electric bill on the 12th of the month
So no penalty will be imposed.

In 2010, Josh purchased a house for $110,000. In 2014, the house was valued at $105,000. What is the rate of change for the value per year?
Final answer:
To find the rate of change for the value of Josh's house per year, subtract the initial purchase price from the current value, then divide by the number of years that have passed. The result shows the house's value decreased by $1,250 per year.
Explanation:
To calculate the annual rate of change for the value of Josh's house, you would subtract the final value of the house from the initial value and then divide by the number of years that have elapsed. This calculation gives you the change in value per year. In this case, the initial value of the house in 2010 is $110,000 and the final value in 2014 is $105,000. There are 4 years between 2010 and 2014.
Rate of change per year = (Final Value - Initial Value) / Number of Years
Rate of change per year = ($105,000 - $110,000) / 4
Rate of change per year = (-$5,000) / 4
Rate of change per year = -$1,250
Therefore, the value of Josh's house decreased by $1,250 per year from 2010 to 2014.
Kenya has 2 hours to work a 100 problem math test.At what rate must she work in order to finish in 2 hours
Answer:
Kenya should solve the problems at the rate 0.83 questions per minute.
Step-by-step explanation:
Total number of hours Kenya has to work on 100 questions is 2 hours .
2 hours = 2x60=120 minutes.
Kenya has to work on 100 problems in 120 minutes .
In 1 minute Kenya can solve 100 ÷ 120= 0.83 questions per minute.
Kenya should solve the problems at the rate 0.83 questions per minute.

which number dose 5 represent a value 10 times the value represented by 5 in 35,187
In 35,187, the digit 5 represents 50,000. Ten times this value is 500,000. Therefore, in the new number, the digit 5 represents 500,000.
To find the value represented by the digit 5 in the number 35,187, we need to consider its place value. In the given number, 5 is in the ten-thousands place, which means it represents 5 * 10,000 or 50,000.
Now, we're asked to find a number where 5 represents a value ten times that of its representation in 35,187. So, we need to multiply 50,000 (the value represented by 5 in 35,187) by 10.
50,000× 10 = 500,000.
Therefore, in the new number, the digit 5 represents 500,000.
To summarize, the number where 5 represents a value ten times its representation in 35,187 is 500,000.

In recent years, 23.8% of all registered doctors were female. If there were 57,800 female registered doctors that year, what was the total number of registered doctors?
Final answer:
To determine the total number of registered doctors, one can use the percentage of female doctors and the number of female doctors to calculate the overall total. By dividing 57,800 by 0.238, you find there were approximately 242,857 registered doctors.
Explanation:
The question asks for the total number of registered doctors, given that 23.8% are female and there are 57,800 female registered doctors. To find this, we use the formula:
Percentage (%) = (Part/Total) × 100
First, we express the percentage as a decimal by dividing it by 100, so 23.8% becomes 0.238. Next, we will rearrange the formula to solve for the Total:
Total = Part / Decimal Percentage
So we have:
Total = 57,800 / 0.238
Doing the calculation:
Total = 242,857 (approx.)
Therefore, the total number of registered doctors is approximately 242,857.
