If two sets are same let a and bthen we can say a= b
according to definition of intersection it is function that contains common enements from both setsas a=b so all elemnts are commonso a= a n bor b = a n b
in union the function has all elements of both sets and in set no element repeats so 
a u b = aor a u b = b
as a u b  = a or b and a n b = a or b so we can conclude here that
a u b = a n b as a = b // defined above

You are buying fruit to make fruit baskets apples come in bags of 20. Ornages come in bags of 16. And bananas come in bags of 32
QveST [7]

Answer:

160 basket of each fruit baskets we can make using all fruit.

Step-by-step explanation:

Given:

Oranges comes in bags = 16

Apples comes in bags = 20

bananas come in bags = 32

We need to find the greatest number of fruit baskets that you can make using all fruit.

Also Given:

You have one bag of each fruit basket must be identical.

So we will first find the least common multiple of all the numbers we get;

20 = 20,40,60,80,100,120,140,160

16 = 16,32,48,64,80,96,112,128,144,160

32 = 32,64,96,128,160

The least common multiple is 160.

Hence we can say that, 160 basket of each fruit baskets we can make using all fruit.

Starting at 6am a bus makes a stop on 1st ave every 8 mins another bus that also starts at 6am makes a stop on 1st ave every 12
Wewaii [24]

9514 1404 393

Answer:

  2.5 times per hour, on average

  {0:00, 0:24, 0:48, 1:12, 1:36} then repeating at 2:00

Step-by-step explanation:

The least common multiple of the intervals is ...

  LCM(8, 12) = 8·12/GCD(8, 12) = 8·12/4 = 24

The two buses will stop at the same time every 24 minutes. That is 60/24 = 2.5 times per hour.

Starting with the 6:00 am stop, the next joint stop is at 6:24, then 6:48. In the next hour, the stops are at 7:12 and 7:36. This sequence of times repeats, starting at 8:00 am. That is, the cycle repeats every 2 hours.
