Answer:
a.More than 3.4 million high school students (mostly juniors and sophomores) take this nationwide, multiple-choice test every year.
Answer: 13
Step-by-step explanation:
Let the number that in thinking of be represented by x.
I multiply by 11 and add 22 will give the same answer as multiplying by 4 and adding 113. This.csn be firmed into an equation as:
(11 × x) + 22 = (4 × x) + 113
11x + 22 = 4x + 113
Collect like terms
11x - 4x = 113 - 22
7x = 91
x = 91/7
x = 13.
The number is 13
7 1/5 - 2 3/5 =
36/5 - 13/5 =
23/5 or 4 3/5 <==
In geometry, the circumference (from Latin circumferences, meaning "carrying around") of a circle is the (linear) distance around it. That is, the circumference would be the length of the circle The area of a circle is pi (approximately 3.14) times the radius of the circle squared.
Answer:
a) Suppose that F is ordered in ascending order:
. Then, the complement of F can be written as

which is the union of a finite number of open intervals, then
is an open set. Thus, F is a closed subset of the real numbers.
b) Take an arbitrary element of F, let us say
. Now, choose a real number
such that
there are not other element of F, because
is less that the minimum distance between
and its neighbors.
In case that
we only consider
, and if
we only consider
.
Then, all points of F are isolated.
