If there are 14 people sitting evenly spaced around a circle which person is directly across from the 2nd person?
Answer:
The 9th
Equation:
14/2=7 so 7 and 14 facing each other
Draw a circle with that
Draw 6 dots on each blank side
2 rom 14 is 2 so 7+2=9
So the answer is 9th
To determine which person is directly across from the 2nd person in a circle with 14 people, person 9 is directly across from the 2nd person.
Explanation:To determine which person is directly across from the 2nd person in a circle with 14 people, we need to use modular arithmetic. If we number the people in the circle from 1 to 14, the person directly across from the 2nd person would be 9th. This can be found by adding 7 (the total number of people in the circle divided by 2) to 2, and then taking the remainder when divided by 14. Therefore, person 9 is directly across from the 2nd person.

Julie works for 48 hours per week for 12 weeks during the summer, making $5000. If she works for 48 weeks during the school year at the same rate of pay and needs to make another $5000, how many hours per week must she work?
Since she only needs to make the same amount of money, if she works for 4 times as many weeks, she can work 4 times fewer hours per week, meaning she can work 1/4*48= 12 hours per week.
During the academic year, Julie needs to put in about 12 hours per week of work to earn an additional $5,000 at the same rate of compensation.
To find out how many hours per week Julie must work during the school year to make another $5000,
set up a proportion using the information we already have.
Let's use the ratio of her earnings to the number of hours worked to create the proportion.
During the summer:
Earnings = $5000
Hours worked = 48 hours/week
Weeks worked = 12 weeks
Summer rate of pay = Earnings / (Hours worked × Weeks worked)
Summer rate of pay = $5000 / (48 hours/week × 12 weeks)
Summer rate of pay = $5000 / 576 hours
Summer rate of pay ≈ $8.68 per hour (rounded to two decimal places)
Now, during the school year, she needs to make another $5000.
So, set up the proportion:
School year earnings = $5000
School year rate of pay = $8.68 per hour (same as the summer rate)
School year rate of pay = School year earnings / (Hours worked × Weeks worked)
$8.68 per hour = $5000 / (Hours worked × 48 weeks)
Now, solve for the number of hours worked per week during the school year:
Hours worked × 48 weeks = $5000 / $8.68 per hour
Hours worked × 48 weeks = 576.036
Hours worked ≈ 12 hours per week (rounded to the nearest whole number)
Therefore, Julie must work approximately 12 hours per week during the school year to make another $5000 at the same rate of pay.

A Gardener has 560 feet of fencing to fence in a rectangular garden. One side of the garden is bordered by a river so it does not need any fencing. What dimensions would guarantee that The Gardener has the greatest possible area
Answer:
Each side of the garden should be 186.67 feet
Step-by-step explanation:
We know that the biggest area of a rectangular prism is when it closer to a square, and we know that a square is a special kind of rectangle with all equal sides, so we want all the sides to be equal.
To do this we know that the Gardener has 560 feet of fencing and he is only going to fence 3 sides because the other side is bordered by a river.
So we have to divide the fencing by the sides to have equal sides:
560 feet / 3 sides = 186.67 feet per side.
So the garden will be a square with each side of 186.67 feet, and the area will be:
186.67 * 186.67 = 34,845.70 square feet.

Courtney has $4.95 in nickels, quarters, and dimes. She has12 quarters and 9 nickels. How many more dimes than nickels does she have?
A. 15
B. 10
C. 6
D. 4
Final answer:
Calculate the difference in the number of dimes and nickels to find out how many more dimes Courtney has. The solution involves determining the total value of quarters and nickels, finding the number of dimes, and subtracting to get the difference. There are 6 more dimes than nickels.
Explanation:
To find how many more dimes Courtney has than nickels:
Calculate the value of quarters: 12 quarters * $0.25 = $3.00
Calculate the value of nickels: 9 nickels * $0.05 = $0.45
Subtract the total value of quarters and nickels from the total amount: $4.95 - $3.00 - $0.45 = $1.50
Since each dime is $0.10, divide $1.50 by $0.10 to find the number of dimes Courtney has: $1.50 / $0.10 = 15 dimes
Calculate the difference between the number of dimes and nickels: 15 dimes - 9 nickels = 6 more dimes than nickels
Therefore, Courtney has 6 more dimes than nickels.

___,___,___
The three values that make this inequality true 3n ≤ 18 are 6, 5, and 4.
We have,
To find three values that make the inequality 3n ≤ 18 true, we can simply substitute different values of n and check if the resulting statement is true or false.
Here are three values that satisfy the inequality:
n = 6:
3n = 3(6) = 18, which is equal to the upper bound of the inequality. Therefore, 3n ≤ 18 is true for n = 6.
n = 5:
3n = 3(5) = 15, which is less than 18. Therefore, 3n ≤ 18 is true for n = 5.
n = 4:
3n = 3(4) = 12, which is less than 18. Therefore, 3n ≤ 18 is true for n = 4.
Note that there are infinitely many values of n that satisfy this inequality, but these three values are enough to demonstrate that the inequality is true for at least three specific values of n.
Thus,
The three values that make this inequality true 3n ≤ 18 are 6, 5, and 4.

B) 1.7 inches
C) 3 inches
D) 3.4 inches
The answer is A) .85 inches
Step-by-step explanation:
A =
1 /2 πr2 4.5 = 1 2 πr2 1.6926 = r
thus, 0.50 in
1 ft = x in 1.6926 ft x = 0.8463
Final answer:
To find the radius of the bay window on the floor plan, calculate the radius of the actual bay window first, apply the scale factor, resulting in a radius of 3.4 inches that is option D is correct.
Explanation:
To find the radius of the bay window on the floor plan, you need to calculate the radius of the actual bay window first. Given the area of the bay window as 4.5 square feet in a semicircle shape, you can use the formula for the area of a semicircle, A = 1/2 * π * r².
Once you find the actual radius, you can then convert it to the scale of 0.5 inch = 1 ft to determine the radius on the floor plan. Remember, the scale factor is the ratio of a length on the drawing to the actual length it represents.
After the calculation, the radius of the bay window on the floor plan is 3.4 inches (Option D).

here is a sketch of y=x^2 + bx + c. the curve intersects the x-axis at (2,0) and point P. the y-axis at (0,14) work out the x-coordinate of the turning point of the graph
Finding the x-coordinate of the turning point of a quadratic equation requires knowledge of its coefficients. Given a function y = x^2 + bx + c, and points (2,0) and (0,14), we need further calculations or information to precisely identify b to use the vertex formula -b/2a effectively.
Explanation:To find the x-coordinate of the turning point of the graph of the quadratic equation y = x^2 + bx + c, we can use the fact that the vertex of a parabola given by the general form ax^2 + bx + c is at x = -b/2a. Since the quadratic intersects the x-axis at (2,0), we can plug x = 2 into the equation to find one relation between b and c.
Another given point is (0,14), which when plugged in gives c = 14. To find b, we need more information from the question or an understanding of quadratic functions more deeply. However, without b, we can use the vertex formula derivatively, knowing that a in our equation is 1 (since the coefficient of x^2 is 1).
We also know that for any quadratic function, the x-coordinate of the vertex (turning point) can be found using -b/2a. Without the exact value of b, we cannot find the exact x-coordinate directly from the information given.
However, the general methodology would involve using the known points to first find equation coefficients and then apply the vertex formula. This highlights the importance of understanding quadratic functions and their graphical representations, such as vertices and intercepts, to solve these types of problems efficiently.
The x-coordinate of the turning point of the graph is 4.5
How to determine the x-coordinate of the turning point of the graph
From the question, we have the following parameters that can be used in our computation:
[tex]y = x^2 + bx + c[/tex]
It intersects the y-axis at (0, 14)
This means that
[tex]0^2 + b(0) + c = 14[/tex]
c = 14
So, we have
[tex]y = x^2 + bx + 14[/tex]
It intersects the x-axis at (2, 0)
So, we have
[tex]2^2 + 2b + 14 = 0[/tex]
4 + 2b + 14 = 0
2b = -18
b = -9
So, we have
[tex]y = x^2 - 9x + 14[/tex]
The x-coordinate of the turning point of the graph is then calculated as
x = -b/2a
So, we have
x = 9/2
x = 4.5
Hence, the x-coordinate of the turning point of the graph is 4.5
