Answer:
Step-by-step explanation:
A larger set that a particular set can be a subset of is a Universal set. A universal set is parent where all other sets are derived from.
For example, given a universal set U = {1,2,3,4,5}, a set A = {1, 3, 5} is said to be a subset of the set U because the elements of set B are contained in the Universal set U.
Also, sets like {1, 4,5} and {3,4,5} can also be regarded as the subset of U since all the elements of the sets can be found in the Universal set U. Hence the correct name of the set is a UNIVERSAL SET
Answer:
Step-by-step explanation:
For any triangle, the Law of Sines is given by .
Using this, we can set up the following equation:
Solving, we get:
Since there are 180 degrees in a triangle:
*It is worth noting that there is more than one possible answer for the measure of angle B. Since , there may be up to two answers when using the Law of Sines to solve for an angle. In this case, there are two possible triangles given the information given, however, only one option is given in the answer choices.
Let the percentage be x%,

Answer:
9/10ths of a mile. Or 0.9 miles.
Step-by-step explanation:
To get the total it's helpful to look at it in decimals:
2/5 mile = 0.4 miles (1 mile divided by 5 = 0.2 miles, times that by 2)
1/2 mile = 0.5 miles
Add them together = 0.9 miles.
Which is 9/10ths of a mile.
