In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

Given is a parallelogram as shown in the image.

Opposite angles of a parallelogram are equal. So, we can write -

x + 50 = y

y - x = 50                                                                  .... Eq { 1 }

Sum of the angles of a quadrilateral are 360°. We can write -

2(x - 30) + (x + 50) + y = 360                                          .... Eq { 2 }

2x - 60 + x + 50 + y = 360

3x + y = 370

3x + 50 + x = 370

4x = 320

x = 80

y = 130

Therefore, the measure of {x} and {y} are 80 and 130 respectively.

Answer:

$141.30

Step-by-step explanation:

180 - 38.70 = 141.30

Answer:

12 houses

Step-by-step explanation:

First you need to figure out how many were sold the first month. You need to figure out how much 1/3 of 48 is, so you need to divide 48 by 3, equaling 16. You then multiply 16 by two, because they didnt sell 1/3, but 2/3. 16 times 2 is 32, so 32 houses were sold in the first month, by doing 48-32, you can say that there were 16 houses left to sell. Then if 1/4 of those houses were sold the next month, then you need to figure out what 1/4 of 16 is. In the same way as before, you divide 16 by 4, which equals 4. If they sold 4 of 16 the next month, you then need to subtract 16 by 4, equaling 12. This means there are 12 houses remaining to be sold.

Answer:

735/420 + 2 = 735/420 + 420/420 = 1155/420

Step-by-step explanation:

To add the three fractions, we need to find a common denominator. A common denominator for all three fractions is 420:

30/15 = 2

25/40 = 25/40 * 3/3 = 75/120

30/35 = 30/35 * 12/12 = 360/420

Adding the three fractions with the common denominator:

2 + 75/120 + 360/420 = 2 + 375/420 + 360/420

Combining like terms:

2 + 735/420 = 2 + 735/420

The answer is 735/420 + 2 = 735/420 + 420/420 = 1155/420.

The sides n and s of the given similar triangles are 12 and 10 respectively.

What are similar triangles?

If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are similar. Similar figures are described as items with the same shape but varying sizes, such as two or more figures.

The polygon with three sides is a triangle. The prerequisites for a triangle's similarity are that the corresponding angles on both triangles must be equal, and the corresponding sides must be proportional to one another.

In the given figure both triangles are similar triangles.

So according to the properties of similar triangles,

[tex]\frac{15}{s} = \frac{9}{6}=\frac{n}{8}[/tex]

For the triangle ABC the interior angles measures ∠A = 80°, ∠B = 58°, and ∠C = 42°.

What are triangles?

Triangles are a particular sort of polygon in geometry that have three sides and three vertices. Three straight sides make up the two-dimensional figure shown here. An example of a 3-sided polygon is a triangle. The total of a triangle's three angles equals 180 degrees. One plane completely encloses the triangle.

According to the angles of a triangle theorem, the sum of angles of a triangle is 180°.

The measure of ∠A = 80°.

The measure of ∠B = 8x + 2.

The measure of ∠C = 6x.

The equation is -

∠A + ∠B + ∠C = 180°

Substitute the values into the equation -

80° + 8x + 2 + 6x = 180

Collect the like terms -

8x + 6x = 180 - 80 - 2

14x = 98

x = 98/14

x = 7°

So, the measure of ∠B = 8(7) + 2 = 58°

The measure of ∠C = 6(7) = 42°

The interior angles of the triangle are 80°, 58° and 42°.

Step-by-step explanation:

You want to know the operation that will give a binomial result from the expressions (3y^6 +4) and (9y^12 -12y^6 +16).

The like terms in the two expressions are 3y^6 and -12y^6, or +4 and +16. Combining these terms by addition or subtraction will not result in the elimination of either the y^6 term or the constant term. Hence addition or subtraction cannot result in a binomial.

We know that the sum of cubes is factored into the product of a binomial and a trinomial:

  a³ +b³ = (a +b)(a² -ab +b²)

Comparing this form to the given binomial and trinomial, we see that we can choose ...

  a = 3y^6

  b = 4

to make the given factors match exactly. That tells us their product will be a binomial sum:

  (3y^6 +4) × (9y^12 -12y^6 +16) = (3y^6)^3 +(4)^3 = 27y^18 +64

The operation "times" (·) will result in a binomial.

Only matrices of the same size can be added or subtracted.

A matrix is a rectangular array of numbers and is composed of rows and columns. In order to add or subtract matrices, the matrices must have the same number of rows and columns. If the matrices do not have the same size, they cannot be added or subtracted.

For example, if one matrix is a 2x3 matrix, the other matrix must also be a 2x3 matrix. Similarly, if one matrix is a 3x2 matrix, the other matrix must also be a 3x2 matrix. The numbers in each matrix may vary, but the size of the matrices must be the same for the operation to be valid.

When adding or subtracting matrices, the numbers in the same position (row and column) are added or subtracted. For example, if one matrix is [[1,2,3], [4,5,6], [7,8,9]] and the other matrix is [[2,4,6], [8,10,12], [14,16,18]], the resulting matrix would be [[3,6,9], [12,15,18], [21,24,27]].

It is important to check that the number of successes and number of failures in each sample is at least 10 because this helps ensure that the normal approximation of the binomial distribution is accurate.

When constructing a confidence interval for the difference between two population proportions, it is important to check that the number of successes and the number of failures in each sample is at least 10 because this helps ensure that the normal approximation of the binomial distribution is accurate. The normal approximation is often used in constructing confidence intervals for proportions because it simplifies the calculations, but it is only accurate if the sample size is large enough.

A common rule of thumb is that each sample should have at least 10 successes and 10 failures in order to ensure that the normal approximation is reasonable. This is because the Central Limit Theorem states that the sum of many independent and identically distributed random variables will approximately follow a normal distribution. When the sample size is large enough, the distribution of the sample proportions will be approximately normal, even if the individual observations are not.

The number of distinct 10-letter arrangements that can be formed from the letters in the word "statistics" is 40320, which can be calculated by finding the permutation of 8 objects taken 8 at a time

Permutation is a mathematical concept that deals with counting the number of ways to arrange a set of objects in a particular order.

The number of permutations of a set of n objects taken r at a time can be calculated using the formula:

=> n! / (n - r)!.

Where "n!" represents n factorial, which is the product of all positive integers less than or equal to n.

In this case, we are going to find out the number of distinct 10-letter arrangements that can be formed from the letters in the word "statistics".

In our case, the number of objects is 8 (the letters in the word "statistics") and we are taking 10 at a time, so the formula becomes:

=> 8! / (8 - 10)! = 8! / (-2)!.

The factorial of a negative number is undefined, so this case is not possible.

Since we cannot take more objects than the number of available objects, we have to find the number of permutations of 8 objects taken 8 at a time. The formula becomes:

=> 8! / (8 - 8)! = 8! / 0! = 8!.

Finally, 8! = 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 40320,

which means that there are 40320 distinct 10-letter arrangements that can be formed from the letters in the word "statistics".

Answer:

Step-by-step explanation:

Given, the sides of triangle ABC are 12, 16 and 20, which form a right triangle (as 20 is the hypotenuse).

Let us assume that the sides of triangle XYZ are x, y and 24 (XZ=24).

Since ABC ~ XYZ, we can use ratios of corresponding sides to find the lengths of the sides of triangle XYZ:

x/12 = y/16 = 24/20

Solving for x and y, we get:

x = 9 and y = 12

So, the perimeter of triangle AXYZ = 9 + 12 + 12 + 24 = 57.

Answer:

The general form of a quadratic equation is ax^2 + bx + c = y.  From the equation for c, our a is -2, our b is -7 and our c is 5.  

When a < 0, the function opens downward and has a maximum for its vertex.

When a quadratic function has maximum, its x values will always be increasing from negative infinity to the x-coordinate of the maximum (You can also simply write x < x coordinate of the maximum as you've already done).

We can find the x-coordinate of the maximum using the equation
