What in mathematics is a linear equation?

An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation. The above is occasionally referred to as a "linear equation with two variables," where y and x are the variables.

x=√2+√3+√6

x - √6 = √2+√3

Squaring both sides

x² - 2x √6 + 6  = 2 + 3 + 2√6  ⇒ x² + 1 = 2√6(1 + x )

Squaring both sides

 x⁴ + 2x² + 1 = 24(  x⁴ + 2x² + 1 )

     ⇒  x⁴  - 22x² - 48x  - 23 = 0

10000-4.75%=find the ratio of a given word

Answer:

(A)24 units

Step-by-step explanation:

Therefore, the perimeter of a rhombus having a side length of 6 centimeters is 24 centimeters.

Solution

P=4a=4·6=24

The perimeter of a rhombus is equal to the sum of all its side lengths. Since all sides of a rhombus are equal to each other, its perimeter is defined as four times one of its side lengths.

A rhombus is a 2-D shape with four sides hence termed as a quadrilateral. It has two diagonals that bisect each other at right angles. It also has opposite sides parallel and the sum of all the four interior angles is 360 degrees.

The perimeter of a shape is always calculated by adding up the length of each of the sides.

The perimeter of a hexagon is the sum of the length of all 6 sides. In regular hexagons, all sides are equal in length. So, the perimeter of a regular hexagon is six times the length of one side.

The perimeter of a hexagon is the sum of the length of all 6 sides. In regular hexagons, all sides are equal in length. So, the perimeter of a regular hexagon is six times the length of one side.

Perimeter of given square =4×6=24cm.

How to find the area of a rhombus if one of its sides and an included angle are given? If “a” be its sides and “θ” is an included angle, then the formula is: Area of a Rhombus = a2 sin θ square units.So, length of side of the rhombus is 5cm.

Hint:A rhombus is a quadrilateral with all sides equal, so the perimeter is 4a and the area of a rhombus is given by, Area = base * height. Area of the rhombus is 30cm2. Perimeter of the rhombus is 0.24m=24cm

The perimeter is the distance around the object. For example, your house has a fenced yard. The perimeter is the length of the fence. If the yard is 50 ft × 50 ft your fence is 200 ft long.

Answer: 22 inches

Step-by-step explanation:

The original dimensions of the index card are 3 inches by 5 inches, so its perimeter is:

P = 2(3 in) + 2(5 in) = 6 in + 10 in = 16 in

and its area is:

A = 3 in x 5 in = 15 in^2

When the map is enlarged to be 8 inches long, the new dimensions are 3 inches by 8 inches, so the perimeter is:

P' = 2(3 in) + 2(8 in) = 6 in + 16 in = 22 in

and the area is:

A' = 3 in x 8 in = 24 in^2

Therefore, the perimeter of the enlarged map is 22 inches and the area is 24 square inches.

Answer:

The new width of the map after enlargement would be (8/5) * 3 = 4.8 inches (assuming the aspect ratio is maintained).

So, the perimeter would be (4.8 + 8) * 2 = 25.6 inches.

The area would be 4.8 * 8 = 38.4 square inches.

Explanation:

Here's an explanation of how to approach problems like these, along with some examples of easy and hard math problems:

When enlarging a map, you need to consider how the scale of the map changes. In this case, the map is being enlarged from 5 inches to 8 inches in length, which is a scale factor of 8/5. This means that every distance on the original map will be scaled up by a factor of 8/5 on the enlarged map.

To find the perimeter and area of the enlarged map, you'll need to use this scale factor to determine the new dimensions of the map. The new width of the map will be the same as the original width, which is 3 inches. The new length of the map will be 8 inches, since that is the length to which the map is being enlarged. So the new dimensions of the map are 3 inches by 8 inches.

To find the new perimeter, you just need to add up the lengths of the four sides of the map: P = 2w + 2l. Using the new dimensions of the map, we get:

P = 2(3) + 2(8) = 6 + 16 = 22 inches

To find the new area, you just need to multiply the new length and width of the map: A = wl. Using the new dimensions of the map, we get:

A = 3(8) = 24 square inches

Examples:

Easy:

The index card is 3 inches wide and 5 inches long, so the perimeter is:

P = 2(3 in) + 2(5 in) = 6 in + 10 in = 16 in

To find the area, we use the formula:

A = L x W

A = 3 in x 5 in = 15 square inches

Now we want to enlarge the map to 8 inches long, but we're not told how wide it will be after enlargement. Let's assume that the width also increases by the same proportion as the length. That means the new dimensions will be:

Length = 8 in

Width = (8/5) x 3 in = 4.8 in

The perimeter will now be:

P = 2(8 in) + 2(4.8 in) = 16 in + 9.6 in = 25.6 in

The area will be:

A = 8 in x 4.8 in = 38.4 square inches

Hard:

A rectangular garden has an area of 320 square feet. If the width of the garden is 10 feet less than the length, find the dimensions of the garden and the length of the diagonal.

Let's use the formula for the area of a rectangle:

A = L x W

We know that the area is 320 square feet, so we can write:

320 = L x (L - 10)

Expanding the right side gives:

320 = L^2 - 10L

Moving all the terms to one side gives:

L^2 - 10L - 320 = 0

We can solve for L using the quadratic formula:

L = (-b ± sqrt(b^2 - 4ac)) / 2a

In this case, a = 1, b = -10, and c = -320, so:

L = (10 ± sqrt(10^2 - 4(1)(-320))) / 2(1)

L = (10 ± sqrt(1440)) / 2

L = (10 ± 12√10) / 2

We can simplify this to:

L = 5 + 6√10 or L = 5 - 6√10

The dimensions of the garden are either:

Length = 5 + 6√10 feet

Width = 5 - 6√10 feet

or

Length = 5 - 6√10 feet

Width = 5 + 6√10 feet

We can check that the area is 320 square feet for either set of dimensions.

To find the length of the diagonal, we can use the Pythagorean theorem:

d^2 = L^2 + W^2

We already know the values of L and W for both cases, so we can calculate:

d = sqrt((5 + 6√10)^2 + (5 - 6√10)^2) = 10 sqrt(2)

or

d = sqrt((5 - 6√10)^2 + (5 + 6√10)^2) = 10 sqrt(2)

So the length of the diagonal is 10 times the square root of 2.

Step-by-step explanation:

We can use the normal distribution to estimate the number of times there would be less than 42 mm of rainfall during August in Claudona over 20 years.

To do this, we need to find the Z-score for 42 mm using the formula: Z = (X - μ) / σ where X is the value we're interested in (42 mm), μ is the mean (48 mm), and σ is the standard deviation (6 mm). Z = (42 - 48) / 6 = -1 Using a Z-score table or calculator, we can find the probability of getting a Z-score less than -1, which represents the probability of getting less than 42 mm of rainfall in August in Claudona: P(Z < -1) = 0.1587

This means that about 15.87% of the time, we would expect there to be less than 42 mm of rainfall during August in Claudona.

To estimate the number of times this would happen over 20 years, we can multiply this probability by the number of years: 0.1587 * 20 = 3.174 Rounding to the nearest integer, we would expect there to be about 3 years over 20 with less than 42 mm of rainfall during August in Claudona.

Answer:

One hot dog costs $1.50 and one hamburger costs $1.75

Step-by-step explanation:

Let x be the cost of one hot dog and y be the cost of one hamburger.

From the first statement, we can set up the following equation:

3x + 4y = 11.5

Similarly, from the second statement, we can set up another equation:

4x + 3y = 11.25

Now we have two equations with two variables. We can solve for x and y using algebraic methods.

One way to do this is to use elimination. We can multiply the first equation by 4 and the second equation by 3, so that we can eliminate one of the variables:

12x + 16y = 46

12x + 9y = 33.75

Subtracting the second equation from the first, we get:

7y = 12.25

Dividing both sides by 7, we get:

y = 1.75

Now we can substitute y = 1.75 into either of the original equations to solve for x. Let's use the first equation:

3x + 4(1.75) = 11.5

3x + 7 = 11.5

3x = 4.5

x = 1.5

Therefore, one hot dog costs $1.50 and one hamburger costs $1.75.

Answer:

D = -13, Dx = 13, and Dy = -78

Step-by-step explanation:

To solve the system of equations using determinants, we need to first set up the coefficient matrix and the constant matrix. The coefficient matrix is formed by the coefficients of the variables, and the constant matrix is formed by the constants on the right-hand side of the equations.

The coefficient matrix for this system is:

```

3 5

2 -1

```

The constant matrix is:

```

27

-8

```

We can now use these matrices to find the values of D, Dx, and Dy.

D is the determinant of the coefficient matrix:

```

| 3 5 |

| 2 -1 |

D = (3 * -1) - (5 * 2)

D = -3 - 10

D = -13

```

Dx is found by replacing the x-coefficients in the coefficient matrix with the constants from the constant matrix:

```

| 27 5 |

| -8 -1 |

Dx = (27 * -1) - (5 * -8)

Dx = -27 + 40

Dx = 13

```

Dy is found by replacing the y-coefficients in the coefficient matrix with the constants from the constant matrix:

```

| 3 27 |

| 2 -8 |

Dy = (3 * -8) - (27 * 2)

Dy = -24 - 54

Dy = -78

```

Therefore, D = -13, Dx = 13, and Dy = -78.

To find x and y, we can use Cramer's rule:

```

x = Dx / D

y = Dy / D

x = 13 / (-13)

x = -1

y = (-78) / (-13)

y = 6

```

So the solution to this system of equations is x = -1 and y = 6.

The median is the middle value. In this case, the middle value is the average of the two middle values (25 and 28). Therefore, the median is:

[tex]\text{Median} = (25 + 28) \div 2 = 26.5[/tex]

To find the mean of the data set, we add up all the values and divide by the number of values:

[tex]\text{Mean} = (14 + 31 + 17 + 28 + 25 + 44) \div 6 = 24.83[/tex] (rounded to two decimal places)

Therefore, the median of the data set is 26.5 and the mean is 24.83.

Answer:

1. x is 37.5

2. x is 20

3. x is approximately 14.2

1. 90 = x + x + 15

We get x by itself and find x is equal to 37.5.

2. 90 = x + 2x + 30

We get x by itself and find x is equal to 20.

3. 90 = 4x + 2x + 5

We get x by itself and find x is approximately around 14.2.

Since the coin has two sides, there are 2^5 = 32 possible outcomes in total. Out of these outcomes, there are only two ways to get the same side every time (either all heads or all tails). Therefore, the probability of getting the same side every time is:

P(E) = favorable outcomes / total outcomes

      =  2/32

      = 1/16 = 0.0625 or 6.25%

So, the theoretical probability of getting the same side every time in five coin tosses is 0.0625 or 6.25%.
