A = {multiples of 3 between 20 and 32} B = {odd numbers between 20 and 32}
C = {even numbers between 20 and 32}
a) List the members of A U B​

A={21,24,27,30}

B={21,27}

C={24,30}

Step-by-step explanation:

a)A U B={21,24,27,30}

b)A n C ={24,30}

9514 1404 393

  A ∪ B = {21, 23, 24, 25, 27, 29, 30, 31}

  A ∩ C = {24, 30}

Step-by-step explanation:

  A = {21, 24, 27, 30} . . . . . . . . . . . . . multiples of 3

  B = {21, 23, 25, 27, 29, 31} . . . . . . . odd numbers

  C = {20, 22, 24, 26, 28, 30, 32} . . . even numbers

The union is the list of numbers in either set.

  A ∪ B = {21, 23, 24, 25, 27, 29, 30, 31}

The intersection is the list of numbers in both sets.

  A ∩ C = {24, 30}

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
