Answer:
Step-by-step explanation:
Juice squeezed from first orange = = 0.235
Juice squeezed from second orange = = 0.3
Juice squeezed from third orange = = 0.45
Juice squeezed from fourth orange = = 0.27
Juice squeezed from fifth orange = = 0.47
Total juice squeezed from all the five oranges = 0.235 + 0.3 + 0.45 + 0.27 + 0.47 = 1.725
Total juice to be squeezed = 2 cups
More juice required = 2 - 1.725 = 0.275
Therefore, to make it 2 cups of orange juice for the family, about cups of more juice is required.
Answer:
Step-by-step explanation:
Let A = R−{0}, the set of all nonzero real numbers, and consider the following relations on A × A.
Given that (a,b) R (c,d) if
Or (a,b) R (c,d) if determinant
a) Reflexive:
We have (a,b) R (a,b) because ab-ab =0 Hence reflexive
b) Symmetric
(a,b) R (c,d) gives ad-bc =0
Or da-cb =0 or cb-da =0 Hence (c,d) R(a,b). Hence symmetric
