Answer:

36290.4$

Step-by-step explanation:

First of all we should find out how much farmer spent on 240 acres

240 × 188.99 = 45357.6

Then, let's find out the price for whole bushels he gets

240 × 60 × 5.67$ = 81648

Therefore his profit is,

81648 - 45357.6 = 36,290.4$//

Answer: We can write an inequality to show how many more inches Bobby needs to grow to reach his desired height by using the following information:

Bobby hopes that he will someday be more than 72 inches tall.

He is currently 59 inches tall.

We can use the inequality x + 59 > 72, where x is the number of inches Bobby needs to grow to reach his desired height.

This inequality represents the total height (x + 59) being greater than the desired height (72).

To solve this inequality, we can subtract 59 from both sides:

x > 72 - 59

x > 13

So, Bobby needs to grow 13 inches or more to reach his desired height.

Answer: (6,2) (0,-2) (-3,-4)

Step-by-step explanation:

If you find the other coordinate pair groups on the graph, there is at least one that doesn't land on the line on the graph.

In the top left, (-6,-5) is not on the graph. If it had been (-6,-6) then it would've been correct, but it isn't.

In the bottom left, (0,-3) isn't on the graph. Instead, (0,-2) is.

In the bottom right, (3,-4) isn't on the graph, but (-3,-4) is.

The exponent x in the equation must be equal to 0.

Here we have the following equation:

16^x^2=8^0

First, notice that any number to the power of zero (except for the number 0) is equal to 1.

a^0 = 1

16^x^2=8^0

16^x^2 = 1

Now, trivially, if we use x = 0 we will get:

c

Particularly, 0^2 = 0

So we can rewrite:

16^0^2 = 1

16^0 = 1

1 = 1

So the solution is x = 1.

In addition to the rectangular form, a complex number can also be represented in polar form. Typically, we write complex numbers as z = x + iy, where I is an imaginary integer. However, in polar form, complex numbers are modelled as a union of argument and modulus.

Given, Some numbers that we need to write in polar form

General formula of polar form = r * [tex]e^{ia}[/tex]

For polar/rectangular conversion we use the following transformations

r² = x² + y²

x = r cosa

y = r sina

Where a is angle

For (a) 1/5

r = 1/5

a = 0

Since angle is 0

Polar form = 1/5

Answer:

The faster cyclist is traveling at 72 miles per hour.

Step-by-step explanation:

We know that the two cyclists are 72 miles apart and meet 3 hours later. We also know that the faster cyclist is 3 times as fast as the slower cyclist.

Let's call the speed of the slower cyclist x miles per hour.

If the faster cyclist is 3 times as fast as the slower cyclist, then their speed is 3x miles per hour.

We can use the formula: distance = speed x time

The distance covered by the slower cyclist is:

x * 3 = 72 miles

The distance covered by the faster cyclist is:

3x * 3 = 72 miles

We can use the formula: distance = speed x time again

x * 3 = 72

x = 24 miles/h

So the slower cyclist is traveling at 24 miles per hour.

To find the speed of the faster cyclist, we know that the faster cyclist is 3 times as fast as the slower cyclist.

The speed of the faster cyclist is:

3 * 24 = 72 miles/h

Answer:

length = 6 cm , breadth = 4 cm

Step-by-step explanation:

the area (A) of the large rectangle = length × breadth

here length = 12 cm and breadth = 4 + x , then

A = 12(4 + x) cm²

the area (A) of the smaller rectangle = x(x + 2)

given area of larger is 4 times area of smaller then

12(x + 4) = 4x(x + 2) ← distribute parenthesis on both sides

12x + 48 = 4x² + 8x , that is

4x² + 8x = 12x + 48 ( subtract 12x + 48 from both sides )

4x² - 4x - 48 = 0 ( divide through by 4 )

x² - x - 12 = 0 ← in standard form

(x - 4)(x + 3) = 0 ← in factored form

equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x + 3 = 0 ⇒ x = - 3

but x must be greater than zero, so x = 4

dimensions of smaller rectangle are

length = x + 2 = 4 + 2 = 6 cm

breadth = x = 4 cm

Answer: Here it is

Step-by-step explanation:

a) The perimeter of a shape is the sum of the lengths of all its sides. In this case, the shape has sides with lengths of 4, 5h, 7, and 2h. Therefore, the expression for the perimeter of the shape can be written as:

Perimeter = 4 + 5h + 7 + 2h

To simplify this expression, we can combine like terms:

Perimeter = 4 + 7 + (5h + 2h)

Perimeter = 11 + 7h

So, the simplified expression for the perimeter of the shape is 11 + 7h

b) The perimeter of the shape is 42.

We can use this information and the expression we found in part a) to find the value of h. We know that:

Perimeter = 11 + 7h = 42

We can subtract 11 from both sides to get:

7h = 42 - 11 = 31

Finally, we can divide both sides by 7 to find the value of h:

h = 31/7

h = 4.428 (approximately 4.43)

Answer: D) 7 3/4

Step-by-step explanation:

With averages, we add all the values and divide by the number of values. Here, we know three out of the four days, let's label the day we don't know x. There are four days, so we can divide by four. 7 1/4 is the average, so we can set the equation equal to 7 1/4.

7 1/4 = (7 1/2 + 7 3/8 + 6 3/8 + x) / 4

Let's multiply both sides by 4 to get rid of the fraction. Let's also add what is in the parentheses

29 = 21 1/4 + x

Now we can isolate x by subtracting 29-21 1/4

so

x = 7 3/4 thus the answer is D

Answer:

D) 7 3/4

Step-by-step explanation:

Let x = amount of last feeding.

7 1/4 = (7 1/2 + 7 3/8 + 6 3/8 + x)/4

4 × 7 1/4 = 7 1/2 + 7 3/8 + 6 3/8 + x

28 + 1 = 7 4/8 + 7 3/8 + 6 3/8 + x

29 = 20 10/8 + x

(20 10/8 is the same as 20 + 10/8 = 20 + 8/8 + 2/8 = 20 + 1 + 1/4 = 21 + 1/4 = 21 1/4)

29 = 21 2/8 + x

29 = 21 1/4 + x

x = 29 - 21 1/4

x = 28 4/4 - 21 1/4

x = 7 3/4

The missing vertices of the square are B(x, y) = (- 2, 1) and D(x, y) = (6, - 7), respectively.

Squares are quadrilaterals with four sides of equal length and four internal right angles. This kind of quadrilaterals have two diagonals perpendicular to each other. In this case, we know the coordinates of the endpoints of diagonal AC and we need to determine the location of points B and D.

This can be done by means of the following definition: A(x, y) = (a, b), C(x, y) = (c, d), B(x, y) = (a, d), D(x, y) = (c, b). If we know that a = - 2, b = - 7, c = 6 and d = 1, then the location of points B and D are, respectively:

B(x, y) = (- 2, 1), D(x, y) = (6, - 7)

F'(7,8)

Step-by-step explanation:

The coordinates of triangle DEF will be D(9,10), E(12,-1), and F(7,8) after the translation.

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

The given triangle DEF has vertices D (3,5), E(6,-6), and F(1,3).

Triangle DEF has translated 5 units up and 6 units right.

This means that the x-coordinates of the vertices D, E, and F will each be increased by 6, and the y-coordinates of the vertices will each be increased by 5.

After the translation, the coordinates of vertex D will be (3 + 6, 5 + 5) = (9, 10)

After the translation, the coordinates of vertex E will be (6 + 6, -6 + 5) = (12, -1)

After the translation, the coordinates of vertex F will be (1 + 6, 3 + 5) = (7, 8)

Answer:

Step-by-step explanation:

Assuming that the area is a rectangle with no obstructions or furniture, and that the people are standing shoulder-to-shoulder, then the area can fit approximately 200,000 people. This is calculated by multiplying 250 feet by 250 feet to get the total square feet of the area, which is 62,500 (250 x 250 = 62,500). Then divide the total square feet by the amount of space taken up by one person, which is 2.5 square feet, to get the approximate number of people that can fit in the area. 62,500 / 2.5 = 25,000, so 25,000 x 8 = 200,000 people.

Answer:

An area that is 20 feet wide and 25 feet long will be 20*25 = 500 square feet large. Division tells us how many times one number is contained within a number, so to find how many 2.5 square feet large people fit in a 500 square feet large space, we do 500/2.5 = 200 people.

Area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.

In these given figure for calculating the area of them we need to divide them into two or more shape like rectangle, triangle or square. For example, I will take Figure 1 and 2

For figure 1

Length of base = 16 + 14 =  30 cm

Length of right rectangle whose side is 14 and 14(smaller one)

Thus, its area = 14 * 14 = 196

Area of left rectangle whose side is 16 and 17 = 16 * 17 = 272

Total area of the figure = 272 + 196 = 468 square cm

For figure 2

If we split them into two shape they will become a square and a triangle

Area of triangle = 1/2 base * height = 1/2 * 6 *3 = 9

Area of square = side * side = 6*6 = 36

Thus, total area = 9 + 36 = 45 square cm
