Each of the other three clerks have to complete 3 reports each.
The top employee finishes 40% of the reports, or: 0.40 x 15 = 6 reports.
Therefore, the other three clerks must finish the remaining 60% of the reports.
Total reports to be completed by the other clerks = 0.60 x 15 = 9 reports
We may distribute the remaining reports evenly among the other clerks since they all have an equal number of reports to complete:
Number of reports each of the other clerks have to complete = 9 reports ÷ 3 clerks = 3 reports
Therefore, each of the other three clerks have to complete 3 reports each.

Graph the solution set
The graph of the inequality is on the image at the end.
How to graph the solution set of the inequality?To graph this, we need to do a solid graph of the linear equation:
y = -(7/2)x + 4
And because the symbol ≥ (and that is why we will use a solid line instead of a dashed line) is used, we need to shade all the region above that line graph.

Answer:

1.154701
Step-by-step explanation:
12x sqaured - 2 = 14
so first add 2 to make it 16 in the other side.
12x sqaured =16 then divide the sqaured and get 4 on the other side
so 12x = 4 then the answer is 4/12 or 1/3
Answer:
Step-by-step explanation:
12x²-2=14 add 2 to both sides
12x²=16 divide both sides by 12
x² = 16/12 reduce by dividing top and bottom by 4
x²=4/3 take square root of both sides to cancel square
when you take sq root you also get ±
x=±[tex]\sqrt{\frac{4}{3} }[/tex] you can take square root of 4
= ± [tex]\frac{2}{\sqrt{3} }[/tex] you can never leave root on bottom so multiply by

Identify the mean, median, mode, and range of the data set. 7, 6, 8, 12, 9, 13, 8
The mean is approximately 9, the median is 9, the mode is 8, and the range is 7.
To find the mean, we add up all the numbers in the data set and divide by the total number of numbers:
Mean = (7 + 6 + 8 + 12 + 9 + 13 + 8) / 7 = 63 / 7 ≈ 9
So the mean is approximately 9.
To find the median, we need to arrange the numbers in order from smallest to largest:
6, 7, 8, 8, 9, 12, 13
Since there are an odd number of values in the data set, the median is the middle value, which is 9.
To find the mode, we need to look for the value that occurs most frequently in the data set. In this case, 8 occurs twice, which is more than any other value, so the mode is 8.
To find the range, we need to subtract the smallest value from the largest value:
Range = largest value - smallest value = 13 - 6 = 7

Jenny has $1200 in her savings account. If the bank pays 3% interest per year on savings, how much interest does she earn in one year?
Jenny earns $36 in interest in one year in her savings account.
To calculate the interest that Jenny earns in one year on her savings account, we can use the formula for simple interest:
I = P x r x t
where I is the interest earned, P is the principal amount (in this case, $1200), r is the interest rate (in decimal form), and t is the time period (in years).
In this case, the interest rate is 3% per year, which can be written as 0.03 in decimal form. The time period is one year. So we have:
I = 1200 x 0.03 x 1
I = $36
Therefore, Jenny earns $36 in interest in one year in her savings account.

In the equation c + a = d + r, a = d + r - c
How to determine the subject of a formula?An equation is simply a mathematical formula that expresses the equality of two expressions, using the equals sign as a connection between them.
Given the equation in the question:
c + a = d + r
To solve for a in the equation c + a = d + r, we need to isolate a on one side of the equation by performing the same operation on both sides of the equation.
c + a = d + r
First, we can simplify the right side of the equation by subtracting c from both sides of the equation:
c + a = d + r
c + a - c = d + r - c
Simplify
a + c - c = d + r - c
a = d + r - c

OA. $1,500.80
OB. $9.92

OD. $150.08
Assuming the Social Security contribution rate is 6.2% of the wage, Ted's contribution to Social Security can be calculated as follows:
Ted's total wage for the month = 160 hours * $10/hour = $1600
Social Security contribution = 6.2% * $1600 = $99.20

Step-by-step explanation:Note that the point is on the circle whose radius is labeled 1, so r=1 or r=−1. Of the choices available, only an angle of −4π3, drawn from the negative x axis plots at the point Q. So θ=−4π3, and r must be negative, as the angle is measured from the negative x axis.

To find the sum of the rational expressions, we need to add the two expressions and simplify if possible:
(2x-1)/(7x+x+2) + (x-2)/(8x-2)
Simplifying the denominators, we get:
(2x-1)/(8x+2) + (x-2)/(8x-2)
Now, we need to find the LCD, which is (8x+2)(8x-2) = 64x²-4:
[(2x-1)(8x-2) + (x-2)(8x+2)] / (64x²-4)
Simplifying the numerator, we get:
[16x²-4x-16x+4+8x²-2x+16x-4] / (64x²-4)
Combining like terms, we get:
(24x²-2) / (64x²-4)
Factoring out a 2 from the numerator and denominator, we get:
2(12x²-1) / 2(32x²-2)
Simplifying further, we get:
(12x²-1) / (16x²-1)
Therefore, the sum of the rational expressions is:

weekend? Express your answer as an improper fraction.
Marcus jogged approximately 2 1/2 miles over the weekend.
How to find the how many miles did he jog over the weekendWe need to discover a common denominator to add the miles run on Saturday and Sunday. Because 10 is the least common multiple of 5 and 2,

In the square pyramid,
Using Pythagoras theorem,
Height of the square pyramid is equal to,
In a right angled triangle,
Base = 18m
Hypotenuse = 30m

A family of mice is collecting pieces of food that fall on the floor in a restaurant. If the mice collect 24 pieces of food every day for 4 days, we want to estimate the number of pieces of food they have collected. Which of the following is the closest estimate to 24?
The estimate the number of pieces of food collected by mice is 96 and closest estimate to 24 is given by option b. 20.
Number of pieces of food collected by mice every day = 24 pieces
Total number of days mice collects the food = 4 days
To estimate the total number of pieces of food collected,
Now, multiply the number of pieces collected each day by the number of days,
Total number of pieces
= 24 pieces/day × 4 days
= 96 pieces
To estimate the answer closest to 24, we can round 24 to the nearest tens.
The nearest tens to 24 is 20.
Therefore, the estimate of collection of food pieces in 4 days by mice is equal to 96 and the closest estimate to 24 is option b. 20.

A direct variation includes the points (2,18) and (n,9). Find n?
The value of the n is 1
In a direct variation, the relationship between two variables is of the form y = kx, where k is a constant of proportionality.
To find the constant of proportionality k in this problem, we can use the fact that the given points satisfy the equation for direct variation.
(2,18) is one of the given points, so we can substitute these values into the equation y = kx and solve for k:
18 = k(2)
k = 18/2
k = 9

Ronald will need 128π square feet to paint all the surfaces of the 8 Columns.
How calculate how much paint Ronald will need to paint all the surfaces of the 8 Columns?
The formula for the total surface area of a cylinder is given by:
A = 2πr(r + h)
Where r is the radius and h is the height
In this case, each wooden cylindrical columns is 7 feet tall and have a diameter of 2 feet. Thus:
r = 2/2 = 1 feet and h = 7 feet
Thus, the total surface area of each wooden cylindrical columns will be:
A = 2π * 1 * (1 + 7)
A = 2π * 1 * 8
A = 16π square feet

The coordinate grid shows points A through K. What point is a solution to the system of inequalities? (1 point) y < −2x + 10 y < 1 over 2x − 2
Answer: (B)
Step-by-step explanation:
To determine which point is a solution to the system of inequalities, we must test each point to see if it satisfies both inequalities. Starting from point A, we plug in its coordinates (2, 9) into both inequalities. However, it does not satisfy y < 1 over 2x − 2. We then move on to point B, which has coordinates (3, 0). Plugging this into both inequalities, we find that it satisfies both of them. Therefore, the point that is a solution to the system of inequalities is point B.
