Answer:
.
Step-by-step explanation:
Since repetition isn't allowed, there would be
choices for the first donut,
choices for the second donut, and
choices for the third donut. If the order in which donuts are placed in the bag matters, there would be
unique ways to choose a bag of these donuts.
In practice, donuts in the bag are mixed, and the ordering of donuts doesn't matter. The same way of counting would then count every possible mix of three donuts type
times.
For example, if a bag includes donut of type
,
, and
, the count
would include the following
arrangements:
Thus, when the order of donuts in the bag doesn't matter, it would be necessary to divide the count
by
to find the actual number of donut combinations:
.
Using combinatorics notations, the answer to this question is the same as the number of ways to choose an unordered set of
objects from a set of
distinct objects:
.
Constants are numbers alone with no variables.
The constants are: 12, -3.7, 1/3
The Area of a Square is the square of the measure of one side of the square.
Hence, given the expression for the area of a square, express the given area as the square of an expression to get the measure of one side.
The given expression is:

Rewrite the expression as:

Recall the binomial expansion:

Substituting a=10x and b=8, it follows that the expression becomes:

Since the area of a square is the square of the measure of one side, it follows that the measure of one side from the given expression is 10x-8.
Answer:
$2.21
Step-by-step explanation:
Given data
Cost = $13.00
Tip= 17%
Let us find the amount of the tip
=17/100*13
=0.17*13
=$2.21
Hence the tip is $2.21
