we are told that JK and KL sides are the same (b/c of the marks) so set them equal and solve for x
8x = 13x-15
8x - 8x + 15 = 13x - 8x -15 + 15
15 = 5x
divide by 5
3 = x
Use the fact that it's 180° around the interior angles of the triangle to solve for y
180 = 5y -3 + 52 + 76
52 = 5y - 3
55 = 5y
11 = y

Answer: 2.88/1
Step-by-step explanation:
an irregular hexagon has interior angles measuring 2x 3x 4x 2x 3x and 97 degrees what's x
The value of x in this case is going to be 24.61 degrees.
How can we prove it ?To find the value of x, we can use the fact that the sum of the interior angles of a hexagon is equal to 180(n-2) degrees, where n is the number of sides of the polygon.
So, the sum of the interior angles of the hexagon = 180(6-2) = 540 degrees
Given that the interior angles measure 2x 3x 4x 2x 3x and 97 degrees.
2x + 3x + 4x + 2x + 3x + 97 = 540
18x + 97 = 540
18x = 443
x = 443/18
x = 24.61 degrees
So, the value of x is 24.61 degrees
What is an hexagon?An hexagon is a polygon with six sides and six angles. It is a two-dimensional shape that can be classified as both a regular or an irregular hexagon. A regular hexagon has all sides and angles congruent, while an irregular hexagon has sides and angles of different lengths and measures. Hexagons can be found in many natural forms such as in honeycomb, crystals and also in man-made structures like in tiles, flooring, and in some parts of the machinery.

Answer:
19 and 29/32 or 19.90625
Step-by-step explanation:
So the 1st Way: We could simplify it and make them into improper fraction in a way like this:
13/4 * 49/8
We can then just multiply the top row and the bottom row:
13 * 49 = 637
4 * 8 = 32
637/32 = 19 and 29/32
The 2nd Way: We could literally add 6 and 1/8, 3.25 times
(I'm so sorry this is a way lol but I couldn't think of another)
6.125 + 6.125 + 6.125 + 6.125(0.25) = 18.375 + 1.53125 = 19.90625 :P

What is the length of the line segment AB is point A is (12, -2) and B is (-4, -8)? Round to the nearest tenth.
Answer:
The length of the line segment AB is 17.1
Step-by-step explanation:
Distance Between two Points in the Plane
Given two points A(x1,y1) and B(x2,y2), the distance between them is:
\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)
We are given the points A(12,-2) and B(-4,-8). Applying the formula:
\(d=\sqrt{(-4-12)^2+(-8+2)^2}\)
\(d=\sqrt{(-16)^2+(6)^2}\)
\(d=\sqrt{256+36}=\sqrt{292}\)
d = 17.1
The length of the line segment AB is 17.1

The graph of f is translated a whole number of units horizontally and vertically to obtain the graph of h
The function f is defined by f(x) = square root of x
Write down the expression for h(x).
The expression for h(x) is,
⇒ h (x) = √(x - 2) + 4
Now, Given that;
Initially the graph f (x) is shifted horizontally to the right.
When the graph shifts to right the function then becomes
f (x) → f (x-b)
Where b is the units by which it is shifted towards right .
So, in the figure we can see that it is shifted 2 units to the right .
So, f(x) → f(x-2)
Since f(x) is,
⇒ f (x) = √x
So, f (x-2) = √x - 2
Now, the new obtained graph is again shifted vertically upward
When the graphs shifts upward;
⇒ f(x) → f(x) + b
where b is the units by which it is shifted upward
So, our obtained f(x-2) when shifted upward by 4 units so using the above given transformation of upward shift
i.e. f(x) → f(x) + b
So, Our new graph h(x) = f(x-2) + 4
⇒ h (x) = √(x - 2) + 4

3 6 9 12 15 18 21 24 27 30 is odd or even numbers?
Answer: Half of them are even and half of them are odd.
Step-by-step explanation:
The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.
The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.
Therefore, out of the given numbers, half of them are even and half of them are odd.

Answer: The possible length of the third side is probably 23cm.
All I did was add 9cm and 15cm which equaled 24cm and you could give that answer or any other number below 24.
Answer:
7 ≤ s ≤ 23; any number of centimeters between 7 and 23 cm.
Step-by-step explanation:
You want to know possible lengths of the third side of a triangle with side lengths 9 cm and 15 cm.
Triangle inequalityThe triangle inequality requires the sum of the two shorter side exceed the longest side. When two sides are given, this means the length of the third side lies between their difference and their sum.
The third side s must satisfy ...
15 -9 < s < 15 +9
6 < s < 24
The third side can have any whole number value between 7 cm and 23 cm, inclusive. For example, it might be 7 cm or it might be 20 cm.

BASEBALL The table below shows the number of stolen bases (B) and times caught stealing (CS) for a few major league baseball teams during the 2013 season. Use linear interpolation to estimate the number of times caught stealing by a team that had 35 stolen bases.
The number of times caught stealing by a team that had 35 stolen bases, using linear interpolation, is of:
37.
What is linear interpolation?Linear interpolation is a method to build a linear function given two points, then we use the function to find a third pair of points of the function.
The two points from the given table are given as follows:
(23, 13) and (28,23).
(any pair of points can be chosen).
Given two points, the slope is obtained as the change in the output divided by the change in the input, hence:
m = (23 - 13)/(28 - 23) = 10/5 = 2.
Hence the function is:
y = 2x + b.
When x = 23, y = 13, hence the intercept b is obtained as follows:
13 = 2(23) + b
b = 13 - 46
b = -33.
Hence the equation is:
y = 2x - 33.
Hence, the number of times caught stealing by a team that had 35 stolen bases is calculated as follows:
n = 2(35) - 33 = 70 - 33 = 37.

You have $1000 to invest in two different accounts. To save the money you need for college, you need to average 6.1 percent interest. If the two accounts pay 3 percent and 7 percent interest, how much should you invest in each account?
$625 in 3%, $375 in 7%
$850 in 3%, $150 in 7%
$450 in 3%, $550 in 7%
$225 in 3%, $775 in 7%
The amount deposited in an account that pays 3% and 7% of interest will be $225 and $775, respectively. Then the correct option is D.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
You have $1000 to put resources into two distinct records. To set aside the cash you really want for school, you really want to average a 6.1 percent premium. Assuming the two records pay a 3% and 7 % premium.
Let 'x' be the amount deposited in an account that pays 3% of interest. Then the amount deposited in another account that pays 7% of interest is (1000 - x). Then the equation is given as,
0.03x + 0.07(1000 - x) = 0.061 × 1000
Simplify the equation, then we have
0.03x + 0.07(1000 - x) = 0.061 × 1000
0.03x + 70 - 0.07x = 61
-0.04x + 70 = 61
0.04x = 70 - 61
0.04x = 9
x = 9 / 0.04
x = $225
Then the amount in the second account will be given as,
⇒ $1000 - $225
⇒ $775
The amount deposited in an account that pays 3% and 7% of interest will be $225 and $775, respectively. Then the correct option is D.

There will always be 12 months in a year. 3 wheels on a tricycle and the amount of stripes in the flag will not change. If the question ask something that can change or vary it is a Statistical question. Like for example "How many minutes do 6th grade students typically spend on homework each week?" and “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question.

There are 24 boys, 30 girls and 10 counselors. Write the ratio of counselors to girls. After you right ratio write it in ratio languages.
Answer:
1:3
Step-by-step explanation:
First, of all, keep in mind that you don't need the number of boys, because it is not in the question. Now we can look at the basic equation, which is "What is the ratio of counselors to girls." That would be Counselor: Girls. There are 10 counselors and 30 girls. Now we need to simplify the ratio. Much like simplifying a fraction, you need to simplify it with the same number. In this case, the best number to simplify with is 10, because it works with both numbers. 30 divided by 3 is 10. 10 divided by 10 is one. Now, lets put this in an easier way to understand:
Counselor = 1
Girls = 3
So, the ratio would be 1:3.
