How do I find x and y

My calculator said the answer was -6

Answer:

40

Step-by-step explanation:

The number of sides also represents the number of angles.

Now, to find the measure of one angle we will need to find the sum of angles first and to do that, we use this very simple formula:

(n-2)*180 (n is the count of interior angles)

7*180 = 1260 and to find the measure of one angle we divide the sum with the number of angles:

1260/9 = 140

now, since the sum of an interior angle and an exterior angle is 180:

180-140 = 40 is the size of one exterior angle

There's an easier way too, just divide the sum of exterior angles by the number of angles

360/9 = 40

Here is how to solve these!

if u want me to solve them too, tell me in the comments.

Step-by-step explanation:

So, u start off by putting in ur mind that u want to solve for x (or the variable) and u start working on that by that following:

-Step one: Isolate the variable, u should remove anything that is at the same side of the equal sign along with the variable to the other side, you do that by flipping the operation in front of it (flip + to -, flip x to /, and vice versa too) for example, you have 3x=6, u isolate x by dividing 3 by both sides, removing it from the side of x and taking it to the other side.

-Step two: After moving the numbers to the other side, make the operation u should be doing, example is now that u have x= 6/3 u won’t leave it standing there, so u solve, and the answer would be 2

-Step three: Piece everything together, now that u have a side with only one number and a side with only a variable, you know what x really is, which is x=2 and this is how u find x

-Additional step: if ur teacher told u to check if ur answer is correct, u check by substituting the variable (x) with the answer u got (2) and solve the equation u had in the first place normally, if the two sides are equal, ur answer was correct, if they are not, u have to solve it again with more focus

ur welcome :)

The congruency statements that are true if triangles JMN and KQR are congruent are:

A. ∠M ≅ ∠Q

E. QK ≅ MJ

F. MN ≅ QR

Two triangles that are congruent to each other will have their corresponding angles and corresponding sides congruent to each other.

Thus, since we assume that △JMN ≅ △KQR, all corresponding angles and sides of both triangles must be congruent.

Therefore, the true congruency statements are:

A. ∠M ≅ ∠Q

E. QK ≅ MJ

F. MN ≅ QR

The two-way table with 5 columns and 3 rows, where the first column is labeled Boys, girls, total, and the entries in the columns match the ones in the second option.

Option B is the correct answer.

A two-way table is a table used to display the frequency distribution of two categorical variables.

It is also called a contingency table because it helps to examine the relationship between two variables, to see if they are dependent or independent.

We have,

A 5-column table has 3 rows.

The first column has entries Boys, girls, total.

The second column is labeled A with entries 12, 16, 28.

The third column is labeled B with entries 24, 30, 54.

The fourth column is labeled C with entries 12, 12, 24.

The fifth column is labeled Total with entries 48, 58, 106, represents the given information.

To understand why this is the correct two-way table, let's go through each row and column of the table:

The first row of the table shows the number of boys and girls who took the test, as well as the total number of students.

We are told that there are 106 total sophomores, so the entry in the "total" column is 106.

We are also told that there are 48 boys who received an A, B, or C on the test, so the entry in the "total" column for boys is 48.

Subtracting this from the total number of students gives us the number of girls:

106 - 48 = 58.

The second row of the table shows the number of students who received an A on the test.

We are told that there are 28 total A's, and out of those, 16 were received by girls.

This means that 28 - 16 = 12 A's were received by boys.

Therefore, the entries in the "A" column are 12 for boys and 16 for girls, which matches the table.

The third row of the table shows the number of students who received a B on the test.

We are told that there are 54 total B's, and out of those, 30 were received by girls.

This means that 54 - 30 = 24 B's were received by boys.

Therefore, the entries in the "B" column are 24 for boys and 30 for girls, which matches the table.

The fourth row of the table shows the number of students who received a C on the test.

We are told that there are 24 total C's, and out of those, 12 were received by boys.

This means that 24 - 12 = 12 C's were received by girls.

Therefore, the entries in the "C" column are 12 for boys and 12 for girls, which matches the table.

Thus,

The two-way table with 5 columns and 3 rows, where the first column is labeled Boys, girls, total, and the entries in the columns match the ones in the second option.

The maximum height is 20 yards and the total horizontal distance is 36 yards, which is the distance between the point (2, 0) and (38, 0).

It is defined as the graph of a quadratic function that has something bowl-shaped.

We have:

The blackbird starts his flight path from (2, 0). His flight path reaches a maximum height of 20 yards and lands at point (38, 0).

Here the bird path will be a parabola with a maximum height of 20 yards.

The total horizontal distance traveled by the bird = The distance between the points (2, 0) and (38, 0)

= √(38-2)²

= 36 yards

Thus, the maximum height is 20 yards and the total horizontal distance is 36 yards, which is the distance between the point (2, 0) and (38, 0).

Step-by-step explanation:

By the Empirical Rule, 99.7% of data in a normal distribution spread across ±3σ standard deviations from the mean μ.

Hence, the range maximum is μ+3σ = 65+3(3) = 65+9 = 74 inches, and the range minimum is μ-3σ = 65-3(3) = 65-9 = 56 inches

Thus, 99.7% of the population will have a height within the range of 56 inches to 74 inches

Step-by-step explanation:

Formula:

[tex]\text{Volume of rectangular prism = Length} \times \text{Width} \times \text{Height}[/tex]

Substitute the length, width, and the volume of the prism in the formula

[tex]\implies \text{2500 = 25} \times 10 \times \text{Height}[/tex]

Divide 25 × 10 to both sides of the equation to isolate "Height"

[tex]\implies \dfrac{\text{2500}}{25 \times 10} = \text{Height}[/tex]

Simplify the left hand side of the equation

Answer: No, the volume is eight times as large

Step-by-step explanation:

      We will test this. Let the radius equal 4, then we will double it to 8.

4 * 2 = 8

    With a radius of 4, the volume is about 268 units³. With a radius of 8, the volume is about 2,145 units³.

        2,145 / 268 = 8

The volume is not twice as large, it is eight times as large.

Why is this? In the formula, r is cubed. WIth an example of 2, 2 * 2 * 2 = 8.

The expression of the solution of the given quadratic equation is gotten as; x = 5 ± 2√3

We want to find the solution to the quadratic equation given as;

x² - 10x + 13 = 0

We will use the quadratic formula to get;

x = [-b ± √b² - 4ac]/2a

x = [-(-10) ± √(-10)² - 4(1 × 13)]/2(1)

x = 5 ± (√48)/2

x = 5 ± (4√3)/2

Approximately 7.81 miles apart.

Step-by-step explanation:

If you were to draw lines between the three points, you would see that it makes a triangle, with leg lengths 6 and 5, like in the attached file.

To find the distance between Hillsboro and Middletown, or the hypotenuse of the triangle, use the Pythagorean Theorem:

6² + 5² = c²

c² = 61

c = √61 = 7.81 miles

The formula for the surface area of a rectangular prism (the storage box) is given by: A=2(wl+hl+hw). In this instance, w = width, h = height, and l = length.

We will calculate the surface area of the box and lid by first determining the height with the storage box lid included.

The height is now 40 cm (= 30 + 10). The width is still 45 cm. The length is still 60 cm.

You can fill in these values: A = 2(wl+hl+hw) = 2((45 * 60) + (40 * 60) + (40 * 45)) = 13,800.
