The measures of the remaining three angles of the decagon are 40, 50 and 130 degrees.
How to find angles of a decagon?A decagon simony means a polygon with 10 sides. In a regular decagon, the interior angles add up to 1440 degrees, and the exterior angles add up to 360 degrees.
Complementary angles sum up to 90 degrees while supplementary angles sum up to 180 degrees.
Therefore,
1440 - 1220 = 220
Let the angles be a, b and c.
Therefore,
a + b + c =220
a + b = 90
b + c = 180
Hence,
a = 220 - 180
a = 40°
b = 90 - 40
b = 50°
c = 180 - 50
c = 130°
The angles are 40°, 50° and 130°.

A teacher bought markers at a cost of $3 per set. The teacher had a $2-off coupon to use
toward the total cost of the markers bought.
Which table shows the relationship between , the number of sets of markers bought by the
teacher, and y, the total cost of the markers?
The first table A shows the relationship between the number of sets of markers bought by the teacher and the total cost of the markers.
From given question, the cost per set of markers = $3
The teacher had a $2-off coupon to use toward the total cost of the markers bought.
It is given that the number of sets of markers bought by the teacher is x, and y is the total cost of the markers.
so, we get a linear equation as:
3x - 2 = y
From table A we can see that the data satisfied the given equation,
3x - 2 = y
when x = 3, y = 3(3) - 2 = $7
when x = 9, y = 3(9) - 2 = $25
when x = 12, y = 3(12) - 2 = $34
when x = 24, y = 3(24) - 2 = $70
Therefore, the first table A shows the relationship between the number of sets of markers bought by the teacher and the total cost of the markers.

What is the name for a straight angle?An angle with something like a vertex point at 180 degrees is considered to be a straight angle in geometry. Basically, it produces a straight line with sides that are turned away from the vertex. "Flat angles" is another term for it.
How do you see a straight angle?A straight line appears to have a straight angle. Here's an illustration of a straight angle. a straight line that has a half circle in the middle and at the top to symbolize a straight angle.
According to the given data:The sum of all angles in triangle = 180.
Angle A = 56
Angle B = 68
Angle C =
A + B + C = 180
56 + 68 + C = 180
124 + C = 180
C = 180 - 124
C = 56
if Angle C = 56
so we know the property of straight angle:
= Angle m + 56 = 180
Angle m = 180 - 56
Angle m = 124
According to the solving the Angle m = 124

determine the interval(s) for which the function shown below is decreasing
Answer:
(∞,-3) and (1,-∞)
Step-by-step explanation:
Decreasing means going down or in math terms, going toward the negatives.
When you are talking intervals in math, you only want to use the x-axis for the interval points. We write the interval as if it was a coordinate point though.
Looking at the graph it looks like it is going from infinity to -3 or written as (∞,3) and from 1 to negative infinity or written as (1, -∞)
The interval(s) for which the function shown below is decreasing are (∞,-3) and (1,-∞).
What is a function?A function is a relationship between two sets of values in mathematics where each input value (or "argument") corresponds to a certain output value.
In most cases, the input values come from a set referred to as the function's domain, while the output values come from a set referred to as the function's range.
Declining is the mathematical phrase for decreasing or moving towards the negatives.
Mathematicians only use the x-axis to represent interval points when discussing intervals. Yet, we express the interval as if it were a coordinate point.
If you look at the graph, it appears to be traveling from infinity to -3, which is written as (,3), and from one to negative infinity, which is written as (1, -).

2 medium boxes, and paid $33. How much does it cost to ship these two sizes of boxes?
Step-by-step explanation:
9)=
By the question:-
x + y = 130-i
x - y = 34-ii
Now,
Add i and ii,
x + y + x -y = 164
or, 2x = 164
so, x = 82
Now,
x -y = 34
or, 82 - y = 34
so, y = 48
The numbers are 82 and 48.

Let adults ticket be x and childs ticket be y.
x + y = 800
x = 800 - y - eqn i
4.5x + 6y = 4500
Substituting x's value from eqn i,
4.5(800-y) + 6y = 4500
or, 3600 - 4.5y + 6y = 4500
or, 1.5y = 900
so, y = 600
Now,
x + y = 800
or, x + 600 = 800
so, x = 200
Hence, 600 adult tickets were sold and 200 child tickets were sold.
11)=
Let cost of one small box be x and one medium box be y.
So,
4x + 2y = 54-eqn i
x + 2y = 33-eqn ii
subtracting eqn i from ii,
x + 2y - 4x - 2y = - 21
or, -3x = - 21
so, x = 7
Now,
x + 2y = 33
or, 2y = 33 - 7
or, y = 26/2
so, y = 13
So, cost of one small box is $7 and medium box is $13.

O d. p=0.04x-68.97
Check Answer
An equation modeling the population, p, of Ohio given the year, t is,
p = 0.04t + 10.98.
What is population?
The term "population" refers to all citizens who are either permanently residing in a country or who are just passing through. This indicator reveals how many people typically reside in a certain area. Growth rates are the population changes that occur each year as a result of births, deaths, and net migration.
Given: In the year 2000, the population of Ohio was 11.03 million people. By the year 2017 the population of Ohio was 11.66 million people.
From this we get, two points (0, 11.03) and (17, 11.66).
First to find the slope using the above two points.
[tex]m=\frac{11.66 - 11.03}{17-0} = \frac{0.63}{17} = 0.04[/tex]
Now to find the equation,
Consider,
p - 11.66 = 0.04(t - 17)
p - 11.66 = 0.04t - 0.68
p = 0.04t - 0.68 + 11.66
p = 0.04t + 10.98
Therefore, the equation modeling the population, p, of Ohio given the year, t is, p = 0.04t + 10.98

The revenue function is given by R(x)=x⋅p(x) dollars where x is the number of units sold and p(x) is the unit price. If p(x)=26(4)−x5, find the revenue if 15 units are sold. Round to two decimal places.
If price p(x) =26(4)^{-x/5}, the revenue when 15 units are sold is equal to $6.09.
How to calculate the amount of revenue at p(15)?From the information provided, the amount of revenue with respect to price that's being generated in this scenario can be calculated by using the following function (expression):
R(x) = x × P(x)
Where:
x represents the number of units sold.p(x) represents the unit price.Since the revenue function, we would simply substitute the value of the unit price and evaluate as follows:
Revenue, R(x) = x × 26(4)^{-x/5}
Substituting the given parameters into the formula, we have;
Revenue, R(x) = 15 × 26(4)^{-15/5}
Revenue, R(x) = 15 × 26(4)^{-3} or (15 × 26)/4³
Revenue, R(x) = 15 × 26(0.015625) or 390/64
Revenue, R(x) = 6.09375 ≈ $6.09.
