Answer:
Option B: (½•16)⅓
Step-by-step explanation:
The associative property states that we can add or multiply numbers in a group regardless of how those numbers are grouped. And that we will get the same answer.
For example;
x(y•z) = (x•y)z = (x•z)y
Now in our question, we want o evaluate; ½(16•⅓)
Using the associative property, the best expression will be: (½•16)⅓
It's the best expression because the terms in the bracket are easy to multiply out without remainder.
Thus, option B is correct
The comparison may be done by the dimensional analysis and the proper conversion factor. That is,
(7.8 x 10^5 m/h) x (1 km / 1000 m) x (24 h / 1 day) = 18720 km / day
The scientific notation of the answer is 1.872 x 10^4 km/day. Thus, the answer is letter D.
Any even number, becasue an odd + an odd equals an even
Answer:
a) and b) satisfied the condition of the given equation.
Step-by-step explanation:
Given: 
≠ 
+ 
Then,
≠ 
a) For a = 21, b = 4 and c = -2, then we have;
≠ 
≠ 
≠
