Answer:

No because Derek only has 4.8 pounds of soil and in the picture there is 5.8 pounds fill up.

Step-by-step explanation:

By solving a system of equations and a quadratic equation, we will see that x = 2.

We know that x and y are positive integers, that x < y and:

x*y = 56

We also know that "seven times the reciprocal of the smaller integer plus 14 times the reciprocal of the larger integer equals 4"

Then we can write the equation:

7*(1/x) + 14*(1/y) = 4

So we have a system of equations:

x*y = 56

7*(1/x) + 14*(1/y) = 4

We can rewrite the first equation to get:

x = 56/y

And the second equation as:

14/y = 4 - 7/x

Then the system becomes:

56/y = x

14/y = (4 - 7/x)

Taking the quotient between these, we can remove the variable y:

(56/y)/(14/y) = x/(4 - 7/x)

56/14 = x/(4 - 7/x)

4*(4 - 7/x) = x

4*(4x - 7)/x = x

4*(4x - 7) = x^2

So now we have a quadratic equation:

x^2 - 16x + 28 = 0

Using the quadratic formula, we will get:

[tex]x = \frac{16 \pm \sqrt{(-16)^2 -4*1*28} }{2*1} \\\\x = \frac{16 \pm 12 }{2}[/tex]

So the solutions are:

x = (16 - 12)/2 = 2

x = (16 + 12)/2 = 14

But notice that if x = 14, then:

14 = 56/y

y = 56/14

y = 4

And y is larger than x, then x = 14 can be discarded.

The solution is x = 2.

The contrapositive of the statement "If the lines are skew, then they are not coplanar" is "If the lines are coplanar, then they are not skew."

The contrapositive of a statement is formed by negating both the hypothesis and the conclusion and switching their positions. The contrapositive of "If P then Q" is "If not Q, then not P."

So, the contrapositive of the original statement "If the lines are skew, then they are not coplanar" is "If the lines are coplanar, then they are not skew" (c).

It is important to note that the contrapositive and the original statement are logically equivalent, meaning that if one statement is true, then the other is also true, and vice versa. This is a useful property in mathematical reasoning and proof writing.

Skew lines are lines that do not lie in the same plane and do not intersect. In other words, they are lines that are not parallel and not coincident. Skew lines have different directions and they can have a 3-dimensional relationship with each other.

In geometry, skew lines are important because they help define the concepts of parallel lines, coplanar lines, and intersecting lines. Skew lines are used to describe the relationship between lines in space, and they are also used in applications such as computer graphics, engineering, and architecture.

Skew lines can also be used to demonstrate the concept of non-Euclidean geometry, which is a type of geometry that does not follow the traditional rules of Euclidean geometry, where parallel lines are equidistant from each other and never meet. In non-Euclidean geometry, parallel lines can diverge from each other and can have a more complex relationship with each other in space.

a power boat takes 30 minutes to travel 10 miles downstream. the return trip takes 50 minutes then the speed of the current is 4mph

distance = speed × time

In this instance, the distance going downstream and upstream is equal. All we need to do is express speed to solve:

Find the speed going upstream and downstream:

10 / 30 = 1/3 mi / min * 60 min / 1 hour  = 20 mph

10 / 50 = 1/5 mi / min * 60 min / 1 hour = 12 mph

Find the speed of the current by expressing a downstream current as + c and upstream current as -c. The speed of the boat (s), without current, would be the same.

s + c = 20

s - c = 12

We can isolate s to solve for c:

s = 20 - c

s = 12 + c

Set the two equations equal to each other:

20 - c = 12 + c

Add c to both sides:

20 = 12+ 2c

Subtract 20 from both sides:

Answer:

A and D

Step-by-step explanation:

The Empirical Rule states that for a bell-shaped distribution, approximately 68% of the data falls within one standard deviation of the mean, approximately 95% falls within two standard deviations of the mean, and approximately 99.7% falls within three standard deviations of the mean.

Given that the mean value of land and buildings per acre from the sample of farms is $1800 and the standard deviation is $300, we can use this information to determine which farms are unusual (more than two standard deviations from the mean).

A. $615 is unusual, it is more than two standard deviations from the mean, which is $1800. $615 is $1185 less than the mean. Since it is more than $600 less than the mean, it is more than two standard deviations from the mean.

B. $1656 is not unusual, it is less than 2 standard deviations from the mean.

C. $1625 is not unusual, it is less than 2 standard deviations from the mean.

D. $2493 is unusual, it is more than two standard deviations from the mean, which is $1800. $2493 is $693 more than the mean. Since it is more than $600 more than the mean, it is more than two standard deviations from the mean.

E. $1521 is unusual, it is more than two standard deviations from the mean, which is $1800. $1521 is $279 less than the mean. Since it is more than $600 less than the mean, it is more than two standard deviations from the mean.

F. $1664 is not unusual, it is less than 2 standard deviations from the mean.

None of the data values are very unusual (more than three standard deviations from the mean).

So the farms that are unusual (more than two standard deviations from the mean) are A and D.

Answer: Using the empirical rule, if the distribution is bell-shaped, we know that about 68% of the data falls within one standard deviation of the mean, about 95% of the data falls within two standard deviations of the mean, and about 99.7% of the data falls within three standard deviations of the mean.

To determine which of the farms are unusual (more than two standard deviations from the mean), we need to calculate the lower and upper bounds for two standard deviations from the mean:

Lower bound = Mean value - (2 * Standard deviation) = $1800 - (2 * $300) = $1200

Upper bound = Mean value + (2 * Standard deviation) = $1800 + (2 * $300) = $2400

So, any data value outside this range is considered unusual. Therefore, the farms that are unusual are:

$2493 (more than two standard deviation from the mean)

None of the data values are very unusual (more than three standard deviations from the mean)

Answer:

40 peaches.

Step-by-step explanation:

We can set up an equation using this information:

(x + 3) * 5 = x * 8

Expanding and simplifying the equation:

5x + 15 = 8x

Subtracting 5x from both sides:

15 = 3x

Dividing both sides by 3:

x = 5

So, if the peaches were shared among 8 people, each person would get 5 peaches. If each person got 3 more peaches if the peaches were shared among 5 people, each person would get 8 peaches.

So the box has 8 peaches per 5 people, 8*5 = 40 peaches

Answer:

There are 8 peaches in the box.

Step-by-step explanation:

It states that if the peaches were shared among 8 people, each person would get x/8 peaches, and if the peaches were shared among 5 people, each person would get x/5 + 3 peaches.

To find the total number of peaches in the box, we can use the equation to find the value of x.

We know that x/8 = x/5 + 3 , we can multiply both sides by 8*5 to get rid of the denominator

8(x/8) = 8(x/5 + 3)

x = 8(x/5 + 3)

5x = 8x + 24

Subtracting x from both sides

3x = 24

Dividing both sides by 4

x = 8

There are 8 peaches in the box.

The solution of the inequality is x < -15/2x.

What is the linear equation?

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. An example of a linear equation is y=mx + b.

We can start solving the inequality by first isolating x on one side of the inequality.

x(2x-1)>15

Divide both sides by x(2x-1)

1>15/(x(2x-1))

To get rid of the fraction, we can invert the inequality and multiply both sides by x(2x-1)

x(2x-1)<15

Now we can simplify the inequality by factoring the left side:

x(2x-1)<15

2x-1 < 15/x

2x < 15/x + 1

2x < (15 + x) / x

Now we can multiply both sides by x

2x*x < 15 + x

2x^2 < 15 + x

Now we can subtract x from both sides

2x^2 - x < 15

Now we can factor the left side

(x-5)(2x+3) < 0

Now we can find the solution of the inequality by finding the values of x that make the inequality true

x = 5, 2x +3 < 0

x < -15/2x

Hence, the solution of the inequality is x < -15/2x.

Answer:

The difference between constant and variable is that, while the first, as we have already said, remains fixed within a formula, the variable can assume different values.

Step-by-step explanation:

A constant term in an expression is a term that has a fixed value and does not change, while a variable term is a term that can take on different values. For example, in the expression 5x + 2, the 2 is a constant term because it is always 2, while x is a variable term that can take on different values.

In a real-world situation, a constant term represents a quantity that does not change. For example, if we were to write an expression to represent the cost of a product, the constant term would be the fixed cost of the product that does not change. On the other hand, a variable term represents a quantity that is subject to change. For example, in the same scenario, the variable term would represent the quantity of the product being bought, which can change.

In summary, a constant term represents a fixed value that does not change, while a variable term represents a value that is subject to change in a real-world situation.

The measures of the angles.

Generally, In a space defined by Euclidean geometry, the sum of the angles of a triangle is equal to the angle that is straight.

A triangle is characterized by the presence of three angles, one at each vertex, and is defined by a set of sides that are next to one another. For a very long time, it was not known for certain whether or not there are alternative geometries for which this sum is different.

The measures of the angles in a triangle add up to 180 degrees. So, to find the measure of each angle in the triangle, we can set up the equation:

14x + 5x + 11x = 180

where

x represents the number of degrees in each angle.

Simplifying this equation, we get:

30x = 180

Dividing both sides by 30, we get:

x = 6

So, each angle in the triangle measures 6 degrees. To find the measure of each angle, we can simply multiply the ratio by 6.

The linearization of the function at a is L(x) = 1/2 + √3/2(x - π/6).

Linearization is a method of taking the gradient of a nonlinear function with respect to all variables. It is used to approximate the output of a function based on the value and slope of the function, at a given point.

The Linearization of function f(x,y) at (a,b) is L(x,y) = f(a,b) + (x−a)fx(a,b) +(y−b)fy(a,b)

Now we take a look at the given function, and the value of point a:

f(x) = sin (x)

a = π/6

Then we differentiate the function, with respect to x:

f(x) = sin (x)

f’(x) = cos (x)

We input the value of a = π/6 into the function:

y = f(π/6)

  = sin (π/6)

  = 1/2

f’(π/6) = cos (π/6)

          = √3/2

Now we input the value of f(a) and f'(a) into the linearization formulas:

L(x) = f(a) + f'(a)(x - a)

      = 1/2 + √3/2 (x - π/6)

Thus the linearization of the function at a is L(x) = 1/2 + √3/2(x - π/6).
