Answer:

a = Negative one-fifth

Step-by-step explanation:

The given equation is :

\(\dfrac{2}{5}+a=\dfrac{1}{5}\)

We need to find the value of a.

Subtract 2/5 from both sides.

\(\dfrac{2}{5}+a-\dfrac{2}{5}=\dfrac{1}{5}-\dfrac{2}{5}\\\\a=\frac{1}{5}-\frac{2}{5}\\\\a=\dfrac{-1}{5}\)

So, the correct answer is Negative one-fifth. Hence, the correct option is (b).

Answer: x= -1

Step-by-step explanation:

In mathematics when you have bases that are the same while multiplying you add the powers. In this case we do not have the same bases so we are going to make it look like 8 is 2. So we sort of simplify it. So we get 8 and put into like 2^4. We do not eliminate the power x that was already there though. So we will have 2^4x × 2^4-x. So like I said earlier we add the powers. Soo we will have

The equation that can be used to solve for c in the given right triangle is the sine function: c = (3 meters) / sin(50°).

In the given right triangle ABC, we are given that angle ACB is a right angle (90°) and angle CBA is 50°. We also know the length of side AC, which is 3 meters. The length of side CB is denoted by "a," and the length of the hypotenuse AB is denoted by "c." To solve for c, we can use the trigonometric function sine (sin). In a right triangle, the sine of an acute angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse. In this case, we can use the sine of angle CBA (50°) to find the ratio between side CB (a) and the hypotenuse AB (c).

The equation c = (3 meters) / sin(50°) represents this relationship. By dividing the length of side AC (3 meters) by the sine of angle CBA (50°), we can find the length of the hypotenuse AB (c) in meters. Using the given equation, we can calculate the value of c by evaluating the sine of 50° (approximately 0.766) and dividing 3 meters by this value. The resulting value will give us the length of the hypotenuse AB, completing the solution for the right triangle.

70 members of the school band play a brass instrument.

Let's start by using variables to represent the number of percussion, woodwind, and brass players. We can call the number of percussion players "P," the number of woodwind players "W," and the number of brass players "B." We are given that the total number of players is 130, so:

P + W + B = 130

We are also given that there are twice as many woodwind players as percussion players, so:

W = 2P

And we are given that there are twice as many brass players as percussion players, so:

B = 2P

We can use substitution to solve for P:

P + 2P + 2P = 130

5P = 130

P = 26

Therefore, there are 26 percussion players, 52 woodwind players (2P), and 52 brass players (2P). So, 70 members of the school band play a brass instrument.

We have,

To determine the common ratio in a geometric sequence, we can divide any term by its preceding term.

Let's apply this to the given sequence: 500, 100, 20, 4.

First, let's divide each term by its preceding term:

100 / 500 = 0.2

20 / 100 = 0.2

4 / 20 = 0.2

We observe that each term divided by its preceding term gives us the same value, which is 0.2.

Therefore, the common ratio in this sequence is 0.2.

To find the 7th term, we can use the formula for the nth term of a geometric sequence:

\(a_n = a_1 \times r^{n-1},\)

where \(a_n\) is the nth term, \(a_1\) is the first term, r is the common ratio, and n is the position of the term.

In this case, the first term \(a_1\) is 500, the common ratio r is 0.2, and we want to find the 7th term \(a_7\).

Plugging these values into the formula, we have:

\(a_7 = 500 \times 0.2^{7-1}\)

= 500 x \(0.2^6\)

= 500 x 0.0064

= 3.2

The sets of transformations that result in the same image when performed in any order are:

Translation, dilation with center (0,0)

Two translations

In mathematics, a transformation refers to a process that changes the size, shape, position, or orientation of a geometric figure or an object in a coordinate plane or space. There are several types of transformations, such as translation, rotation, reflection, and dilation, which are used to alter the original figure to create a new one that is similar or congruent to the original. Transformations are used in geometry, algebra, and other branches of mathematics to study and understand various properties of geometric shapes and objects.

Here,

For the first set, if we perform a translation followed by a dilation with center (0,0), the result will be the same as if we perform the dilation first followed by the translation. This is because the dilation does not change the direction of the translation, and the center of dilation is at the origin, so the translation is unaffected.

For the second set, any two translations can be combined to form a single translation, so the order in which they are performed does not matter.

The dimensions of the pen that minimize the total cost of fencing are approximately 21.21 feet by 42.43 feet.

To determine the dimensions that minimize the total cost, we need to apply a different approach. In this case, we can solve for one variable in terms of the other using the equation for the area:

900 = L × W

Rearranging the equation, we have:

W = 900 / L

Substituting this expression for W into the cost function C, we get:

C = 40L + 20(900 / L)

Simplifying further, we have:

C = 40L + 18000 / L

To minimize C, we can take the derivative of C with respect to L and set it equal to zero:

∂C/∂L = 40 - 18000 / L² = 0

Multiplying through by L², we have:

40L² - 18000 = 0

Dividing through by 40, we get:

L² - 450 = 0

Solving this quadratic equation, we find:

L = ±√450

Since L represents a length, we consider the positive value:

L ≈ 21.21 feet

Substituting this value of L back into the equation for W, we have:

W = 900 / 21.21 ≈ 42.43 feet

To find dz/dt using the chain rule, we need to calculate the derivatives of z with respect to x and y separately, and then multiply them by the derivatives of x and y with respect to t.

Given:

z =  \(cosh^{2} (xy)\)

x = (1/2)t

y = \(e^{t}\)

Let's start by finding the partial derivatives of z with respect to x and y:

∂z/∂x = \(2cosh(xy) * sinh(xy) * y\)  (using the chain rule)

∂z/∂y = \(2cosh(xy) *sinh(xy)*x\)    (using the chain rule)

Next, let's find the derivatives of x and y with respect to t:

dx/dt = 1/2

dy/dt = \(e^{t}\)

Finally, we can use the chain rule to find dz/dt:

dz/dt = (∂z/∂x)(dx/dt) + (∂z/∂y)(dy/dt)

      = \(2cosh(xy) *sinh(xy)*y*(1/2) + 2cosh(xy)*sinh(xy)*x*e^{t}\)

Now, substitute the given expressions for x and y:

\(dz/dt = 2cosh((1/2)t*e^{t} * sinh((1/2)t*e^{t} *(1/2)* + 2cosh((1/2)t*e^{t} *sinh((1/2)t*e^{t} *((1/2)t)\)

Simplifying further, we have:

\(dz/dt = cosh((1/2)t*e^{t} *sinh((1/2)t*e^{t})* e^{t} + cosh((1/2)t* e^{t}*sinh((1/2)t*e^{t}* ((1/2)t)\)

Answer: 5x4=20

And 5+4=9

Step-by-step explanation:

The required two numbers are 4 and 5.

"It is a statement which consists of equal symbol between two mathematical expressions."

For given example,

We need to find two number such that if multiply then we get 20 and add to get 9.

Let 'a' and 'b' be two numbers.

According to given conditions,

a × b = 20                .........................(i)

a + b =9                    .......................(ii)

So, from given conditions we have two equations (i) and (ii).

From equation (ii) we have,

a = 9 - b                    ...............(iii)

Substitute above value of 'a' in equation (i),

⇒ (9 - b) × b = 20

⇒ 9b - b² = 20

⇒ b² - 9b + 20 = 0

Now we solve this quadratic equation to find b.

⇒ b² - 9b + 20 = 0

⇒ b² - 5b - 4b + 20 = 0

⇒ (b - 5) (b - 4) = 0

⇒ b = 5 or   b = 4

Find the value of 'a' from equation (iii)

When b = 5

⇒ a = 9 - 5

⇒ a = 4

When b = 4

⇒ a = 9 - 4

⇒ a = 5

Therefore, the required two numbers are 4 and 5.

Answer:

distance = 11.1803 units

midpoint :  (-1.5, 6).

Step-by-step explanation:

To plot the points A(4, 5) and B(-7, 7) on the grid, we locate the points at the coordinates (4, 5) and (-7, 7) respectively.

The distance between two points (x1, y1) and (x2, y2) can be calculated using the distance formula:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Plugging in the values for A and B, we get:

d = √((-7 - 4)^2 + (7 - 5)^2)

d = √(11^2 + 2^2)

d = √(121 + 4)

d = √125

d = 11.1803 (rounded to hundredths place)

The midpoint of two points (x1, y1) and (x2, y2) can be calculated as follows:

x = (x1 + x2) / 2

y = (y1 + y2) / 2

The midpoint of A and B is:

x = (4 - 7) / 2 = -1.5

y = (5 + 7) / 2 = 6

So the midpoint of A and B is approximately (-1.5, 6).

Let's use "x" to represent the length of a side of the smaller polygon, and let's use "y" to represent the corresponding length of a side of the larger polygon. We're told that the ratio of the side lengths is 3/5, so we can set up the equation:

y/x = 5/3

We're also told that the perimeter of the smaller polygon is 60 inches, so we can set up another equation using the fact that the smaller polygon has "n" sides:

nx = 60

Now, we want to find the perimeter of the larger polygon, which also has "n" sides. We can use the equation we set up earlier to write "y" in terms of "x":

y/x = 5/3

y = (5/3)x

Now we can substitute this expression for "y" into the formula for the perimeter of the larger polygon:

Perimeter of larger polygon = nx = n(5/3)x = (5/3)(nx) = (5/3)(60) = 100

So the perimeter of the larger polygon is 100 inches.

A standard bowling lane is approximately 60 feet long from the foul line to the head pin.

The metric system uses the terms kilometres (km), metres (m), decimeters (dm), centimetres (cm), and millimetres (mm) to describe length or distance.

A standard bowling lane is designed to be 60 feet in length from the foul line to the head pin. This distance is consistent across most bowling alleys and is a key measurement in the sport of bowling.

The 60-foot length is divided into specific sections that contribute to the overall structure of the lane. These sections include the approach area, the foul line, the lane itself, and the pin deck where the pins are set.

The approach area is the section where the bowler stands and prepares to release the ball. It usually spans around 15 feet, providing enough space for the bowler to take a few steps and build momentum before releasing the ball.

The foul line marks the boundary between the approach area and the actual lane. It is important for bowlers to release the ball before crossing the foul line; otherwise, it is considered a foul, and the resulting throw does not count towards the score.

Beyond the foul line is the lane, which is where the ball rolls towards the pins. The lane is typically around 41 to 42 inches wide, made of a specially coated wooden or synthetic surface that allows the ball to roll smoothly.

At the end of the lane is the pin deck, where the pins are arranged in a triangular pattern. The head pin, also known as the 1-pin, is positioned at the front of the triangle. When the ball reaches this area, it interacts with the pins, causing them to scatter or fall, resulting in a score.

Overall, the 60-foot length of a standard bowling lane provides enough distance for bowlers to exhibit skill and strategy in their throws while ensuring a fair and consistent playing field.
