Answer:

\large\boxed{\{4,\ 7,\ 10\}}

Step-by-step explanation:

X\ \cup\ Y\\\text{The union of a collection of sets is the set of all elements in the collection.}\\\\X\ \cap\ Y\\\text{The intersection}\ X\cap Y\ \text{of two sets X and Y is the set that contains}\\\text{all elements of X that also belong to Y, but no other elements.}\\\\A'\\\text{When A is a subset of a given set U, the absolute complement A}\\\text{is the set of elements in U, but not in A.}

U=\{3,\ 4,\ 5,\ 6,\ 7,\ 8,\ 9,\ 10\}\\A=\{4,\ 6,\ 8\}\\B=\{3,\ 4,\ 7,\ 10\}\\C=\{3,\ 5,\ 9\}\\\\A\ \cup\ B=\{4,\ 6,\ 8\}\ \cup\ \{3,\ 4,\ 7,\ 10\}=\{3,\ 4,\ 6,\ 7,\ 8,\ 10\}\\C'=\{3,\ 4,\ 5,\ 6,\ 7,\ 8,\ 9,\ 10\}-\{3,\ 5,\ 9\}=\{4,\ 6,\ 7,\ 8,\ 10\}\\B\ \cap\ C'=\{3,\ \b4,\ \b7,\ \b1\b0\}\ \cap\ \{\b4,\ 6,\ \b7,\ 8,\ \b1\b0\}=\{\b4,\ \b7,\ \b1\b0\}\\\\(A\ \cup\ B)\ \cap\ (B\ \cap\ C')=\{3,\ \b4,\ 6,\ \b7,\ 8,\ \b1\b0\}\ \cap\ \{\b4,\ \b7,\ \b1\b0\}=\{\b4,\ \b7,\ \b1\b0\}

Carson uses cubes to make a pattern of shapes. The first shape has a height of
KIM [24]

Answer:

The length of each shape will alternate  between even numbers and odd

numbers.​

Step-by-step explanation:

A cube is a 3 dimensional object that has equal length, width and height. It is has area of a cube.

Carson uses 2 cubes for the height and length for a start. He adds 1 cube to the length and height with respect to each stage. Since the length of each cube is the same, then consistent addition increases the length by same factor.

The length of each cube equals 1 unit, then he starts with 2 (length equals 2 units), next stage add 1 to make up 3(length equals 3 units). He add another 1 more for another stage to make up 4 (length equals 4 units)... This addition continues depending on the number of stages required.

Therefore, it can be deduced that the length of each shape will alternate

between even numbers and odd  numbers.

I need help with a logic puzzle. It's called popular new secretary
LenKa [72]
The puzzle goes like this:
A popular new secretary at the law firm of Farnsworth, Newman, O’Malley, Price, and Reynolds, is taken to lunch by a different one of those five men on each of her first week on the job. Each man took her to eat at a different one of these five types of food: Chinese, French, Greek, Indian, and Mexican.

From the information given, determine whom she went to lunch with on each day and the type of food that they had.

1. Neither Mr. Newman nor Mr. Reynolds took her to lunch on Thursday or Friday but one took her for Chinese food and the one who took her lunch earlier than the other her for Greek food.
2. She went for a Mexican food lunch before her Indian food lunch but after her lunch with Mr. Price.
3. She had lunch with Mr. Farnsworth before her lunch with Mr. O’ Malley but after the lunch when she French food, which was not on Monday.
4. She has lunch with Mr. Newman later in the week than than the lunch when she had French food.

To solve the puzzle, we list the possible entries for each day.

For the person she went ot with:
Monday: Reynolds, Newman, Price
Tuesday: Reynolds, Newman, Price
Wednesday: Reynolds, Newman, Price, Farnsworth
Thursday: Farnsworth, O'Malley
Friday: O'Malley

For the food she ate:
Monday: Greek,
Tuesday: Greek, Chinese, Mexican, French
Wednesday: Chinese, Indian, Mexican, French
Thursday: Indian, Mexican,
<span>Friday: Indian

</span>From information (1): Reynolds and Newman can either be on Monday, Tuesday or Wednesday. Greek food can either be on Monday or Tuesday while Chinese food can either be on Tuesday of Wednesday (since Greek food came before Chinese food).
From information (2): Indian food can either be on Wednesday, Thursday or Friday while Mexican food can either be on Tuesday, Wednesday or Thusday. She went out with Price either on Monday, Tuesday or Wednesday.
From information (3): She ate French food either on Tuesday or Wednesday. Farnsworth took her out either on Wednesday or Thursday while O'Malley took her out either on Thursday or Friday.
From information (4): She has lunch with Mr. Newman later in the week than than the lunch when she had French food. This means that she ate French food on Tuesday and went out with Newman on Wednesday.

Thus the solution is:
   Day             Person                   |        Food
 Monday:       Reynolds                 |        Greek
Tuesday:          Price                     |        French
Wednesday:  Newman                  |       Chinese
Thursday:    Farnsworth                |       Mexican
<span>Friday:           O'Malley                  |         Indian</span>
