The roster method to write the set A' as {13, 16, 17}.
- "Set" is a collection of distinct objects, which can be numbers or other elements.
- "Roster method" is a way of listing all the elements in a set by separating them with commas and enclosing them within braces { }.
Now, let's find set A', which is the complement of set A with respect to set U. This means that A' contains all the elements in U that are not in A.
U = {12, 13, 14, 15, 16, 17, 18}
A = {12, 14, 15, 18}
To find A', we will list the elements from set U that are not in set A:
A' = {13, 16, 17}
So, using the roster method, the complement of set A (A') is written as:
A' = {13, 16, 17}
In summary, the roster method is useful for listing all the elements in a set. By finding the complement of set A with respect to set U, we can use the roster method to write the set A' as {13, 16, 17}.

The triangle below is equilateral. Find the length of side x to the nearest tenth.
x
12
Answer:
6.9
Step-by-step explanation:
You want half the side length of an equilateral triangle with an altitude of 12.
Pythagorean theoremThe altitude shown divides the base into equal parts. If one of those parts is x, then the full side length is 2x. The Pythagorean theorem relates the side lengths of the right triangle:
(2x)² = x² +12²
3x² = 144 . . . . . . . . subtract x²
x² = 48 . . . . . . . . divide by 3
x = √48 = 4√3 . . . take the square root
x ≈ 6.9
__
Additional comment
You should be familiar with the fact that a 30°-60°-90° triangle has side lengths in the ratio 1 : √3 : 2. This means the shortest side (x) will have a length of 12/√3 ≈ 6.9, since the middle-length side is shown as having a length of 12.

Six familie went to the food fetival. Each family ha 2 adult and 4 childern. The entry fee for each child ticket cot $4, and an adult ticket cot $8. What would be the total cot of the fetival ticket?
The total cost of the festival tickets for 6 families with 2 adults and 4 children would be $192.
We can start by using the following equation to find the total cost of the child tickets:
Child tickets cost = Number of child tickets x Cost per child ticket
In this case, the number of child tickets is 4 children/family x 6 families = 24 children
The cost per child ticket is $4.
So, the total cost of the child tickets would be:
24 children x $4/child = $96
Similarly, we can find the total cost of the adult tickets:
Adult tickets cost = Number of adult tickets x Cost per adult ticket
In this case, the number of adult tickets is 2 adults/family x 6 families = 12 adults
The cost per adult ticket is $8.
So, the total cost of the adult tickets would be:
12 adults x $8/adult = $96
To find the total cost of the festival tickets, we can add the cost of the child tickets and the cost of the adult tickets:
Total cost = Child tickets cost + Adult tickets cost
$96 + $96 = $192
So, the total cost of the festival tickets for 6 families with 2 adults and 4 children would be $192.

A box with a square base and no top is to be made from a square piece of carboard by cutting 7 in squares from each corner and folding up the sides. The box is to hold 7623 in How big a piece of cardboard is needed?
The size of the cardboard piece required is 7627.0 in.
The formula for finding the size of a box is
2(L + W) + 8L + 8W = Perimeter of the cardboard piece
Where L = Length, W = Width
We need to find L and W to find the size of the cardboard piece.
7623 = 2(L + W) + 8L + 8W
7623 = 2L + 2W + 8L + 8W
7623 = 10L + 10W
7623/10 = L + W
762.3 = L + W
Let's take L = 500 and W = 262.3 (762.3 - 500 = 262.3)
Now we plug in the values of L and W in the original formula
2(500 + 262.3) + 8(500) + 8(262.3) = 7623
2(762.3) + 4000 + 2102.4 = 7623
1524.6 + 4000 + 2102.4 = 7623
7627.0 = 7623
Therefore, the size of the cardboard piece required is 7627.0 in.

What is word problem?
A math word problem is a question that is written as one or more sentences and asks students to use their mathematical understanding to solve an issue from "real world." In order to understand the word problem, they must be familiar with the terminology that goes along with the mathematical symbols that they are used to.
Here , Let us take Number of card Alan has as A and Number of card bill has as B and Number of cards does Calvin has as C.
Now Alan has 11 less than 2 times the number of cards Bill has then,
=> A = 2B-11 ------------->1
And Calvin has 1 more than 1 times the number of cards Bill has then,
=> C = B+1 ----------> 2
Here Alan and Calvin has same number of cards then
=> 1 = 2
=> 2B - 11 = B +1
=> 2B-B = 11+1
=> B = 12
Now put B= 12 into 1 then
=> A = 2(12)-11= 24-11 = 13
Now put B= 12 into 2 then
=> C = 12+1 = 13
Hence the number of cards Alan has is 13 and Number of cards Calvin has is 13.

4/5 and 6/10 form a proportion.
Which ratios form a proportion iready ?A proportion is a statement that two ratios are equal. In order for two ratios to be considered a proportion, the two ratios must be multiplied by the same number to yield the same result.Doing so is called cross-multiplying. In this case, 4/5 can be cross-multiplied to get 8/10, which is equal to 6/10.Since 4/5 and 6/10 are both equal when cross-multiplied, they are considered a proportion.In addition to cross-multiplying to confirm that two ratios form a proportion, the two ratios can also be written as a fraction and simplified.In this case, the two ratios can be written as 4/5 = 6/10.The fraction can then be simplified to 2/3 = 3/5.This method of simplifying the fraction is another way to confirm that the two ratios are a proportion. In conclusion, 4/5 and 6/10 form a proportion because they are equal when cross-multiplied, and they simplify to 2/3 and 3/5, respectively.To learn more about ratios form a proportion iready refer to:
