Answer:

1 1/8 of a mile.

Step-by-step explanation:

The distance around the track is one quarter of a mile. Therefore, if you run around the track 4 times, you will have ran 1 mile, as 4 * 1/4 = 1. You would also run the other 1/2 of the lap, and to find that distance, you would multiply 1/2 * 1/4, because you only ran 1/2 of a lap and not one whole lap, which would come out to 1/8 of a mile. So, your final answer would be 1 + 1/8 of a mile, which comes out to 1 and 1/8 of a mile.

The profit percent made by the green grocer on the sale of the grapefruits is 50%.

To calculate the profit percent, we need to determine the profit made on the sale of the grapefruits.

The grocer buys a box of 150 grapefruits for $12, which means the cost of each grapefruit is $12/150 = $0.08.

The grocer sells each grapefruit for 12 cents, which is $0.12.

The profit made on each grapefruit is the selling price minus the cost price: $0.12 - $0.08 = $0.04.

Now, we can calculate the total profit by multiplying the profit per grapefruit by the number of grapefruits: $0.04 * 150 = $6.

To find the profit percent, we divide the profit by the cost price and multiply by 100: ($6 / $12) * 100 = 50%.

Therefore, the profit percent is 50%.

Answer:

If the tickets are priced at $20 each, the total amount of money taken in would be $88,000.

Step-by-step explanation:

To write the number of tickets sold, n, as a function of the ticket price, p, we can use the given information that for every $1 increase in price, 200 tickets go unsold.

Let's define the slope of the line as the decrease in tickets per dollar increase in price. Since 200 tickets go unsold for every $1 increase, the slope of the line is -200.

Now, let's find the equation of the line through the given points: (12, 6000), (13, 5800), (14, 5600), and so on.

Using the point-slope form of a linear equation, we have:

n - 6000 = -200(p - 12)

Simplifying the equation, we get:

n - 6000 = -200p + 2400

Rearranging the equation to solve for n, we have:

n = -200p + 8400

This equation represents the number of tickets sold, n, as a function of the ticket price, p.

To find how much money will be taken in if the tickets are $20 each, we substitute p = 20 into the equation:

n = -200(20) + 8400

n = -4000 + 8400

n = 4400

If the tickets are $20 each, the number of tickets sold would be 4400. To calculate the total amount of money taken in, we multiply the number of tickets sold by the ticket price:

Money taken in = Number of tickets sold * Ticket price

Money taken in = 4400 * $20

Money taken in = $88,000

The formulas for the piecewise function graphed below are:
f(x) =  x + 3  for -2 ≤ x < 0, 3 for 0 ≤ x < 2, -2x + 7 for  2 ≤ x ≤ 4.

The piecewise function graph provided consists of three distinct pieces.

To give the formulas for each piece, we can break it down as follows:
For the left piece:
The left piece of the graph starts at x = -2 and ends at x = 0. It appears to be a linear function with a positive slope. Let's call this function f₁(x).
The formula for the left piece, f₁(x), can be written as:
f₁(x) = mx + b
To find the slope (m) and y-intercept (b), we can use two points on the graph.

From the graph, we can see that when x = -2, y = 1. And when x = 0, y = 3.
Using the formula for slope (m):
m = (y₂ - y₁) / (x₂ - x₁)
m = (3 - 1) / (0 - (-2))
m = 2 / 2
m = 1
Substituting the values of m and one of the points (x, y) into the equation, we can solve for the y-intercept (b):
1 = 1(-2) + b
1 = -2 + b
b = 1 + 2
b = 3
Therefore, the formula for the left piece is:
f₁(x) = x + 3
For the middle piece:
The middle piece of the graph starts at x = 0 and ends at x = 2. It appears to be a horizontal line.

Let's call this function f₂(x).
The formula for the middle piece, f₂(x), can be written as:
f₂(x) = c
To find the value of c, we can observe that the y-values of this piece are all equal to 3.

Therefore, the formula for the middle piece is simply:
f₂(x) = 3

When x = 2, y = 3. And when x = 4, y = -1.
Using the formula for slope (m):
m = (y₂ - y₁) / (x₂ - x₁)
m = (-1 - 3) / (4 - 2)
m = -4 / 2
m = -2
Substituting the values of m and one of the points (x, y) into the equation, we can solve for the y-intercept (b):
3 = -2(2) + b
3 = -4 + b
b = 3 + 4
b = 7
Therefore, the formula for the right piece is:
f₃(x) = -2x + 7
To summarize, the formulas for the piecewise function graphed below are:
f(x) =
x + 3     for       -2 ≤ x < 0
3           for       0 ≤ x < 2
-2x + 7   for      2 ≤ x ≤ 4

Answer:

y = (-1/6)x represents a proportional relationship.

Answer:

Therefore, the amount (future value) of the ordinary annuity is approximately $19,446.27.

Step-by-step explanation:

We can use the formula:

FV = P * [(1 + r/n)^(n*t) - 1] / (r/n)

where we will consider :

FV is the future value,

P is the periodic payment,

r is the interest rate per period,

n is the number of compounding periods per year, and

t is the number of years.

Now given :

P = $1300 (payment per semiannual period)

r = 4.5% per year (or 0.045 as a decimal)

n = 2 (compounded semiannually)

t = 8 years

Plugging in these values into the formula, we will be getting:

FV = 1300 * [(1 + 0.045/2)^(2*8) - 1] / (0.045/2)

Calculating this expression will give us the future value (amount) of the ordinary annuity:

FV = 1300 * [(1 + 0.0225)^(16) - 1] / 0.0225

FV ≈ $19,446.27 (rounded to the nearest cent)

Answer:

The area of the complex figure is approximately 210.92 square units.

Step-by-step explanation:

Let's calculate the area of the complex figure with the given information.

We can break the figure down into three components: an equilateral triangle, a right triangle, and a rectangle.

1. Equilateral Triangle:

The height of the equilateral triangle is given as 4.33 units. We can calculate the area using the formula:

Area of Equilateral Triangle = (base^2 * √3) / 4

In this case, the base of the equilateral triangle is also the length of side d, which is given as 13 units.

Area of Equilateral Triangle = (13^2 * √3) / 4

Area of Equilateral Triangle ≈ 42.42 square units

2. Right Triangle:

The right triangle has two sides with lengths a (5 units) and b (5 units), and its hypotenuse has a length of side c (also 5 units).

Area of Right Triangle = (base * height) / 2

In this case, both the base and height of the right triangle are the same and equal to a or b (5 units).

Area of Right Triangle = (5 * 5) / 2

Area of Right Triangle = 12.5 square units

3. Rectangle:

The rectangle has a length equal to side d (13 units) and a width equal to side e (12 units).

Area of Rectangle = length * width

Area of Rectangle = 13 * 12

Area of Rectangle = 156 square units

Now, to get the total area of the complex figure, we add the areas of each component:

Total Area = Area of Equilateral Triangle + Area of Right Triangle + Area of Rectangle

Total Area = 42.42 + 12.5 + 156

Total Area ≈ 210.92 square units

Therefore, the area of the complex figure is approximately 210.92 square units.

The vertices of the image triangle N'M'O' are N'(5, 2), M'(2, 1), and O'(3, 3).

To determine the vertices of the image N'M'O' after reflecting triangle NMO over the line x = -1, we need to apply the reflection transformation to each vertex.

For a reflection over the line x = -1, we can find the image of a point (x, y) by finding its reflection as (2(-1) - x, y).

Applying this transformation to each vertex of triangle NMO, we get:

N' = (2(-1) - (-5), 2) = (5, 2)

M' = (2(-1) - (-2), 1) = (2, 1)

O' = (2(-1) - (-3), 3) = (3, 3)

To graph the function g(x) = 7x + 10, we shift the graph of f(x) = 7x vertically by adding a constant term of +10. This means every y-coordinate on the graph increases by 10 units. The slope of the line remains the same at 7. The resulting graph is a straight line passing through (0, 10) with a slope of 7.

To graph the function g(x) = 7x + 10, you need to make the following change to the graph of f(x) = 7x:
1. Translation: The graph of f(x) = 7x can be shifted vertically by adding a constant term to the equation. In this case, the constant term is +10.
Here's how you can do it step by step:
1. Start with the graph of f(x) = 7x, which is a straight line passing through the origin (0,0) with a slope of 7.
2. To shift the graph vertically, add the constant term +10 to the equation. Now, the equation becomes g(x) = 7x + 10.
3. The constant term of +10 means that every y-coordinate of the points on the graph will increase by 10 units. For example, the point (0,0) on the original graph will shift to (0,10) on the new graph.
4. Similarly, if you take any other point on the original graph, such as (1,7), the corresponding point on the new graph will be (1,17) since you add 10 to the y-coordinate.
5. Keep in mind that the slope of the line remains the same, as only the y-values are affected. So, the new graph will still have a slope of 7.
By making this change, you will have successfully graphed the function g(x) = 7x + 10.
