Answer:
<u>Rajeev walked at 3.5 miles per hour of speed</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Distance Rajeev walked = 7/8 of a mile = 0.875 miles
Time of walking = 1/4 of an hour = 15 minutes
2. What was the speed in miles per hour?
Let's use the Direct Rule of Three for answering this question, as follows:
Distance in miles Time in minutes
0.875 15
x 60
*************************************************
15x = 0.875 * 60
15x = 52.5
x = 52.5/15
x = 3.5
<u>Rajeev walked at 3.5 miles per hour of speed</u>
Adding the two equations will be adding similar terms to both equations. That is:
8x + (-8x) = 0
-10y + (-6y) = -16y
20 + (-4) = 16
Therefore, adding the two equations will look like -16y = 16. (Option 3)
The Volume is 4.5ft.

The <em>correct answer</em> is:
A∪B={}
Explanation:
Since A∩B = ∅, we know that A and B have no elements in common. This means they are disjoint.
Since the universal set is made up of A and B, and A and B have no elements in common, then A is equal to the complement of B, or A = B'.
Since A and B have no elements in common, A is not a subset of B.
Since we are told at the beginning that A and B are not the empty set, there is no way that their union would be empty. The union of A and B, or A∪B, would contain at least two distinct elements, one from A and one from B.
