Sudoku is a number puzzle game that involves filling in a 9x9 grid with digits from 1-9, with the objective being to ensure that each row, column, and 3x3 sub-grid contains all of the digits from 1 to 9.

To solve a sudoku puzzle, it is best to start with the easiest cells first, usually those with the fewest possibilities. Look for cells that only have one possible answer and fill them in. Then, move on to more difficult cells and use logic and deduction to fill in the remaining numbers. It is also helpful to use pencil marks to keep track of possible numbers for each cell. The key to solving sudoku is to be patient, persistent, and to use logic and deduction to work through the puzzle.

Answer: 9 laps in 1 day = 18 laps in 2 days

Step-by-step explanation:

To complete the proportion, we can use the fact that the number of laps is directly proportional to the number of days:

9 laps in 1 day = 18 laps in x days

To solve for x, we can use the property of proportions that the product of the means equals the product of the extremes:

9 laps × x days = 1 day × 18 laps

Simplifying, we get:

9x = 18

Dividing both sides by 9, we get:

x = 2

Therefore, the missing number to complete the proportion is 2. The complete proportion is:

9 laps in 1 day = 18 laps in 2 days

Answer: 2 days

Step-by-step explanation: 9 + 2 equals 18 therefor 18 laps in 2 days

The area of the purple ring is 10,843.079 ft²

Remember that for a circle of radius R the circumfernce is:

C = 2*3.14*R

Here we know that the circumference of the inner circle is C = 221.056 ft

Then the radius will be:

221.056 ft = 2*3.14*R

221.056 ft/(2*3.14) = R

35.2 ft = R

Then the radius of the outer circle is:

R' = 35.2ft + 33.3ft = 68.5 ft

The area of the ring is the diffence between the areas of the larger circle and the smaller circle, then:

area = 3.14*( (68.5 ft)² - (35.2 ft)²) = 10,843.079 ft²

The angle of polygons is an important concept in geometry and can be calculated using the formula (n-2) x 180. Quadrilaterals are a specific type of polygon with four sides and four angles, and their interior angles can be found by dividing the sum of the interior angles by the number of sides.

The angle of polygons is an important concept in geometry. A polygon is a closed shape with three or more sides, and the angles of a polygon are the interior angles formed by the sides. Quadrilaterals are a specific type of polygon with four sides and four angles.

To find the sum of the interior angles of a polygon, you can use the formula (n-2) x 180, where n is the number of sides. For example, a quadrilateral has four sides, so the sum of its interior angles would be (4-2) x 180 = 360 degrees.

Each individual angle of a quadrilateral can be found by dividing the sum of the interior angles by the number of sides. So for a quadrilateral, each angle would be 360/4 = 90 degrees.

Answer:

Step-by-step explanation:

The strength of a linear relationship between two variables is typically measured by the correlation coefficient (r) or the coefficient of determination (r^2). A value of r or r^2 closer to 1 indicates a stronger positive linear relationship, whereas a value closer to -1 indicates a stronger negative linear relationship. A value of r or r^2 closer to 0 indicates a weaker or no linear relationship.

Looking at the given regression equations and their correlation coefficients, the regression with the weakest linear relationship between x and y is Regression 3:

Regression 1: y = -5.8x - 6.5, r = -0.7621

Regression 2: y = 2.4x - 14.7, r = 0.809

Regression 3: y = -7.4x - 17.4, r = -0.233

Regression 4: y = -3.4x - 8.5, r = -0.6121

Regression 3 has the lowest absolute value of r (0.233), indicating the weakest or no linear relationship between x and y. Therefore, Regression 3 represents the weakest linear relationship between x and y among the given options.

C is the correct answer. If there is a total of 399 pages, adding the pages she has left to the pages she has already read (266 pages) it would equal the total, that she has to read 133 pages still.

Answer: c = 54

Step-by-step explanation:

c/6 = 9

c/6*(6) = 9*6

c = 54

Answer: c = 54

Step-by-step explanation:

c/6 = 9

you then multiply c/6 by it's denominator, which in this case 6. What you do on one side, you have to do to the other.

6 · c/6 = 9 · 6

Then you multiply everything, 6 cancels out denominator 6 which leaves C and 9 turns into 54. Meaning c equals 54.

c = 54

To check, you can replace c with 54 in your original equation.

The number of ways two names can be chosen from 76 in a raffle where only one entry is allowed is 3,025.

This can be calculated by using the combination formula: nCr = n!/(r!(n-r)!), where n is the total number of names (76) and r is the number of names to be chosen (2). The calculation for the same is written out below:

nCr = 76!/(2!(76-2)!)

= 76!/(2!*74!)

= 3,025.

This means that there are 3,025 possible combinations of two names that can be chosen from the 76 names if only one entry is allowed per person.

Answer:

It is called a solution.

There is no general rule that says a system of linear equations cannot have exact solutions that are integers greater than 1. The existence of such solutions depends on the specific coefficients and constraints of the system

It is not true that a system of linear equations cannot have exact solutions that are integers greater than 1. In fact, there are many systems of linear equations that have such solutions.

However, there are certain types of systems of linear equations that do not have integer solutions, or may not have any solutions at all. For example, if the coefficients of the variables in the equations are irrational numbers, then it is possible that the system has no integer solutions.

Furthermore, some systems of linear equations may have solutions that are not integers, but are instead fractions or irrational numbers. This is because the solutions to a system of linear equations are determined by the intersection points of the lines or planes that represent the equations, and these intersection points may not always fall on integer coordinates.

The capital letter H has 2 reflectional symmetry and 2 rotational symmetry.

A figure has reflectional symmetry if it can be reflected across a line and still look the same. For the capital letter H, there is two lines of symmetry, which is the vertical line and horizontal line that divides the letter into two equal halves. Reflecting the letter across this line produces the same letter. So, the H has only 2 reflectional symmetries.

A figure has rotational symmetry if it can be rotated by some angle and still look the same. For the capital letter H, if we rotate it 180 degrees and 360 degrees about the center point of the letter, it will look the same. There is no other angle of rotation that produces the same letter.

To prove that two triangles △ABC and △DEF are similar, we can use the following theorem:

The Angle-Angle (AA) Similarity Theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

Or else, if ∠A ≅ ∠D and ∠B ≅ ∠E, then △ABC ~ △DEF. This theorem relies on the fact that when two angles of one triangle are congruent to two angles of another triangle, the third angle must also be congruent due to the fact that the sum of the angles in a triangle is always 180 degrees. Thus, the triangles must have the same shape and are therefore similar.

Step-by-step explanation:

To find what the ratio would be, we need to know what to multiply 5 & 3 by so that when we add them, we get 80. Let's assume the number we multiply by is x:

5x + 3x = 80

8x = 80

x = 80 / 8

x = 10

Now, we multiply 5 by 10 and 3 by 10

= 50:30

Your ratio would be 50:30

Double check: 50 + 30 = 80

The ratio of roses to daisies is 2:5. If there are 40 roses, then there are 100 daisies.

In the garden, the ratio of roses to daisies is 2:5. This means that for every 2 roses, there are 5 daisies. We can use this information to find the number of daisies when there are 40 roses.

Set up a proportion using the given ratio and the number of roses.
   2/5 = 40/x

Cross multiply to solve for x, we get:
   2 * x = 5 * 40

Then, simplify the expression:
2x = 200

Divide both sides by 2 to isolate x.
x = 100

Therefore, there are 100 daisies in the garden when there are 40 roses.
