Answer:
c) {(1,3), (2, 4), (1, 4), (2,3)}
Step-by-step explanation:
Since, the cartesian product of two sets A and B is defined as,
A × B = {(a, b) : a ∈ A and b ∈ B},
Here, the given sets,
A = {1, 2},
B = {3, 4}
Thus, by the above definition,
A × B = { (1, 3), (1, 4), (2, 3), (2, 4) }
Hence, option 'c' is correct.
Follow along with the pattern, for example if it is going by 2's then you would write a 4
1.0892*10²

2 x 4 = 8
2 x 3 = 6

Answer:a) $5.64 b) 21 ounces of tea leaves
Step 1
5 ounces of tea leaves can be bought with $2.35
1 ounce of tea can be bought with =$2.35/5 =$0.47
12 ounces at the same rate can be bought with
=12 x $0.47 = $5.64
b) 5 ounces of tea leaves can be bought with $2.35
? Ounces of tea leaves can be bought with $10
$2.35 =5 ounces of tea
$10 = ? ounces of tea
= (10 x 5)/2.35
=50/2.35
=21.27 rrounded to 21 ounces of tea leaves
