Find the sun of the interior angles for each polygon
Answers
Answer:
360
1080
Step-by-step explanation:
We can find the sum of the interior angles of any regular polygon by using this formula
(n - 2) * 180
where n = number of sides
For the square: the square has 4 sides
To find the sum of the interior angles we simply substitute 4 for n in the formula
Formula: (n - 2) * 180
Substitute 4 for n
(4 - 2 ) * 180
Subtract 4-2
2 * 180
Multiply
= 360
The sum of the interior angles of the first polygon is 360
For the second one:
We will repeat this exact process the only difference is the value of "n"
The polygon shown has 8 sides
So to find the sum of the interior angles we simply substitute 8 for n in The formula
Formula (n - 2) * 180
Substitute 8 for n
(8 - 2) * 180
Subtract 8 - 2
6 * 180
Multiply
= 1080
The interior angles of a 8 sided figure will add up to 1080

deck that is four feet wide. What is the area of the surface of the deck?
Answers
Answer: 160 sq. feet
Step-by-step explanation:
Given: Dimension of rectangular pool :
Length = 20 feet
width = 15 feet
Area of rectangular pool = length x width
= 20 feet × 15 feet
= 300 sq. feet
Now, Length of deck = 20 feet + 4 feet+ 4 feet (For both sides)
= 28 feet
width of deck = 15 feet + 4 feet+ 4 feet = 23 feet
Area of deck including pool = 20 feet × 23 feet
= 460 sq. feet
Area of deck = (Area of deck including pool ) -(Area of rectangular pool)
= 460 - 300 sq. feet
= 160 sq. feet
Hence, the area of the surface of the deck= 160 sq. feet

2x + -3y = 19
Step-by-step explanation:
In this question, they already gave you the equation of the line. But it is in point-slope form. We just need to rearrange the equation to look like:
Ax + By = C
A and B and C should be positive or negative whole numbers. So let's get rid of the fraction first.
y + 1 = 2/3 (x - 8)
You could use distributive property on the right side, but that is just going to make two terms have fractions. Instead, let's multiply both sides by 3 and get rid of the fraction.
3(y + 1) = 3• 2/3(x-8)
3(y + 1) = 2(x - 8)
Now use distributive property.
3y + 3 = 2x - 16
We need x and y on the left and plain numbers on the right.
3y + 3 = 2x - 16
Subtract 3
3y = 2x - 19
Subtract 2x
3y - 2x = -19
Rearrange the x and y terms, put x in the lead.
-2x + 3y = -19
This is almost standard form. The A is supposed to be positive. So change the sign of ALL the numbers. A is 2, the B is -3 and the C is 19. Those are the numbers that go in the blanks on your question.

Determine whether gender and passing the test are independent by filling out the
blanks in the sentence below, rounding all probabilities to the nearest thousandth.
Passed Failed
Male 25 10
Female 20 8
Answers
P(female) × P(fail) = 0.100 and P(female and fail) = 0.127, the two events are not equal so the events are dependent.
We can calculate the probabilities as follows:
Total number of students = 25 + 10 + 20 + 8 = 63
P(female) = Number of females / Total number of students
= 20 / 63
= 0.317
P(fail) = Number of students who failed / Total number of students
= (10 + 8) / 63
= 0.317
P(female and fail) = Number of female students who failed / Total number of students
= 8 / 63
= 0.127
Since P(female) × P(fail) = (0.317) × (0.317) = 0.100 and P(female and fail) = 0.127, the two events are not equal so the events are dependent.
Therefore, based on the calculations, we can conclude that gender and passing the test are dependent events, not independent.

Answers
In order to lose one pound for weight per week, Maddie must consume 1800 calories per day.
Firstly we need to know the number of calories Maddie wants to loose. As per the fact, 1 pound equals 3500 calories. Thus, she must eat 3500 calories less than regular in a week.
Now, one week has seven days. So, number of calories to be reduced each day = 3500/7
Number of calories = 500 calories.
The required calorie intake = current calorie intake - calories to not be consumed
Required calorie intake = 2300 - 500
Required calorie intake = 1800 calories.
Thus, Maddie must consume 1800 calories per day.

To calculate depletion expense, first determine the depletion per unit. depletion per unit can be calculated by taking (cost ______)/total units of capacity.
Answers
To calculate depletion expense, you need to determine the depletion per unit. The depletion per unit can be calculated by taking (cost of the resource) / total units of capacity.
Depletion is an accounting method used to allocate the cost of natural resources over their useful life. It is commonly used in industries such as mining, oil and gas extraction, and timber harvesting, where companies extract and deplete natural resources as part of their operations.
The first step in calculating depletion expense is to determine the cost of the resource. This includes all costs incurred to acquire and develop the resource, such as exploration costs, development costs, and acquisition costs. These costs are typically capitalized and then allocated over the estimated recoverable units of the resource.
Once you have determined the cost of the resource, you need to calculate the total units of capacity. This refers to the estimated amount of resource that can be extracted or harvested from the reserve. For example, in mining, it could be measured in tons of ore, while in oil and gas extraction, it could be measured in barrels or cubic feet.
To calculate the depletion per unit, divide the cost of the resource by the total units of capacity. This will give you the amount of depletion expense that should be recognized for each unit extracted or harvested.
It's important to note that there are different methods for calculating depletion expense, such as units-of-production method and percentage depletion method. The units-of-production method calculates depletion based on actual production or extraction during a given period. On the other hand, the percentage depletion method allows for a fixed percentage deduction from gross income based on statutory rates.
In conclusion, to calculate depletion expense, you need to determine the depletion per unit by dividing the cost of the resource by the total units of capacity. This allows for an appropriate allocation of costs over the useful life of natural resources.

The points (1,7) (13,16) and (5,k), where k is an integer, are vertices of a non-degenerate triangle. What is the sum of the values of k for which the area of the triangle is a minimum?
Answers
The sum of the values of k for which the area of the triangle is a minimum is 10.
To find the sum of the values of k for which the area of the triangle is a minimum, we need to determine the possible values of k.
Given that the area of the triangle is 10, we can use the formula for the area of a triangle:
Area = 1/2 * base * height
We can choose any two sides of the triangle as the base and height. Let's consider the sides formed by the points (1,7) and (13,16) as the base.
The length of the base is the distance between these two points:
base = sqrt((13-1)^2 + (16-7)^2) = sqrt(144 + 81) = sqrt(225) = 15
Since the area is 10, we can substitute the values into the formula:
10 = 1/2 * 15 * height
Simplifying the equation, we find:
height = 20/3
Now, let's find the equation of the line passing through the points (1,7) and (13,16) to determine the possible values of k.
The slope of the line is given by:
m = (16-7)/(13-1) = 9/12 = 3/4
Using the point-slope form of a linear equation, we have:
(y - 7) = (3/4)(x - 1)
Rearranging the equation, we find:
4y - 28 = 3x - 3
Simplifying, we get:
4y = 3x + 25
Substituting x = 5 (since the point (5,k) lies on the line), we can solve for k:
4k = 3(5) + 25
4k = 15 + 25
4k = 40
k = 10
Therefore, the sum of the values of k for which the area of the triangle is a minimum is 10.

Find an equation for the level surface of the function through a given point. x - y + 2z/2x + y - z, (3, 0, -1) An equation for the level surface passing through the point (3, 0, 1) is z =
Answers
the equation for the level surface passing through the point (3, 0, 1) is x + 2y - 3z = 0. The given function is f(x, y, z) = (x - y + 2z) / (2x + y - z). We are asked to find an equation for the level surface passing through the point (3, 0, 1).
To find the equation for the level surface, we need to set the function equal to a constant value and solve for z.
Let's start by substituting the coordinates of the given point into the function:
f(3, 0, 1) = (3 - 0 + 2(1)) / (2(3) + 0 - 1)
= 5 / 5
= 1
So, the constant value for the level surface passing through (3, 0, 1) is 1.
Now, let's set the function equal to 1 and solve for z:
1 = (x - y + 2z) / (2x + y - z)
Cross-multiplying, we get:
2x + y - z = x - y + 2z
Rearranging the terms, we have:
x + 2y - 3z = 0
Therefore, the equation for the level surface passing through the point (3, 0, 1) is x + 2y - 3z = 0.
In summary, the equation for the level surface passing through the point (3, 0, 1) is x + 2y - 3z = 0.
