Answer:

A ∩ B = {1, 3, 5}

A - B = {2, 4}

Step-by-step explanation:

The given problem regards sets and set notation, a set can simply be defined as a collection of values. One is given the following information:

A = {1, 2, 3, 4, 5}

B = {1, 3, 5, 6, 9}

One is asked to find the following:

A ∩ B,

A - B

1. Solving problem 1

A ∩ B,

The symbol (∩) in set notation refers to the intersection between the two sets. It essentially asks one to find all of the terms that two sets have in common. The given sets (A) and (B) have the values ({1, 3, 5}) in common thus, the following statement can be made,

A ∩ B = {1, 3, 5}

2. Solving problem 2

A - B

Subtracting two sets is essentially taking one set, and removing the values that are shared in common with the other set. Sets (A) and (B) have the following values in common ({1, 3, 5}). Thus, when doing (A - B), one will omit the values ({1, 3, 5}) from set (A).

A - B = {2, 4}

mina [271]

Answer:

Total space needed is 3136 square feet.

Step-by-step explanation:

We are given the following in the question:

Space required for eight manufacturing processes and six stockpiles.

Each takes 160 square feet.

Space required for 8 process =

=8\times 160\\=1280\text{ square feet}

Space required for 6 stockpiles =

=6\times 160\\=960\text{ square feet}

Total space =

=1280 + 960\\=2240\text{ square feet}

Open space required = 40%

=\dfrac{40}{100}\times 2240\\\\=896\text{ square feet}

Total space required =

=2240 + 896\\=3136\text{ square feet}

Thus, total space needed is 3136 square feet.
