We are asked to find out how much wood is needed to make the circular bottom of a birdhouse if the diameter of the bottom is 12 inches​.

Recall that the circumference of a circular shape is given by

Where π is a constant and r is the radius.

The radius and diameter of a circle are related as

So, the circumference of the circle becomes

Therefore, 36.7 inches of wood is needed to make the circular bottom of a birdhouse.

Monthly payments and total loan costs on a 30-year loan at an APR of ​9% are 1027.27 and for a 15-year loan at an APR of ​8.5% are 1297.82.

Formula to computer the periodic payment for a loan with principal P, periodic interest rate R, and several payments T:

(P × R)([tex](1-(1+r)) ^{-T}[/tex])

Option 1, there are 30×12=360 monthly payments, and the monthly interest rate is 8%÷12.

By applying all the given values P=140000, R= 8%÷12 and T = 360 in P÷([tex](1-(1+r)) ^{-T}[/tex]),

(140000 × (9% ÷ 12))÷(1 - [tex](1 + \frac{9}{12} )^{-360}[/tex] ) = 1027.27

In option 2, there are 12 × 15 = 180 monthly payments, and the monthly interest rate is 7.5% ÷ 12. Applying the formula (P × R)([tex](1-(1+r)) ^{-T}[/tex]), the monthly payment is:

(140000 × (8.5% ÷ 12))÷(1 - [tex](1 + \frac{8.5}{12} )^{-180}[/tex] ) = 1297.82

A note with a face value of $8200 was discounted If the discount was $200, the length of the loan in days will be 178 Days.

A loan is when money is lent to another person with the understanding that it would be repaid, along with interest. Before agreeing to provide a borrower with a loan, lenders will take into account the borrower's income, credit score, and degree of debt.

Let us consider the number of days to be 'D'

8200 * 5% * (D / 365) = $200

D = (200 * 365) / (8200 * 0.05)

D = 7300 / 41

D = 178 Days.

Therefore, the loan's duration in days will be 178 Days.

Based on the time it takes to patrol one neighborhood, the number of neighborhoods that the sheriff can patrol in 5/8 of an hour is 3.125 neighborhoods

The number of neighborhoods that the sheriff can patrol in 5/8 hours depends on the number of hours that it takes the sheriff to patrol one neighborhood.

The number of neighborhoods she can patrol can therefore be found by the formula:

= Number of hours sheriff has / Number of hours required to patrol one neighborhood

= 5/8 ÷ 3/15

= 5/8 x 15/ 3

= 75 / 24

Explanation:

Let's identify the coordinates of the initial and final triangle.

R = (-4, 5)

S = (-2, 5)

T = (-4, 1)

In the same way,

R' = (3, 2)

S' = (5, 2)

T' = (3, -2)

So, we can say that the translation was 7 units to the right and 3 units down, so the rule will be:

(x, y) ---> (x + 7, y - 3)

If we apply this rule to the points R, S, and T, we get:

R(-4, 5) ---> (-4 + 7, 5 - 3) = R'(3, 2)

R(-4, 5) ---> (-4 + 7, 5 - 3) = R'(3, 2)

R(-4, 5) ---> (-4 + 7, 5 - 3) = R'(3, 2)

1.The value of the expression after simplify will be,

''negative 43 over 24 times j plus negative 1 over 12.''

Option D is true.

2. The equivalent expression will be;

⇒ - 19.5b - 6.9

What is mathematical expression?

Expression in math is defined as the collection of the numbers, variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is;

''The expression negative one eighth j plus two thirds minus the expression five thirds j plus nine twelfths.''

Now, We can write the expression in mathematical form as;

⇒ (- 1/8  j + 2/3) - (5/3 j + 9/12)

Solve the expression as;

⇒ - 1/8 j + 2/3 - 5/3 j - 9/12

⇒ - 1/8 j - 5/3 j + 2/3 - 9/12

⇒ j (-1/8 - 5/3) + 2/3 - 3/4

⇒ j (- 3 - 40)/24 + (8 - 9)/12

⇒ j (-43/24) + (- 1/12 )

This can be written as;

''negative 43 over 24 times j plus negative 1 over 12''

Therefore, The value of the expression after simplify will be,

''negative 43 over 24 times j plus negative 1 over 12.''

Option D is true.

Solution

- The question asks us for the leading coefficient of the following polynomial

Explanation

Leading Coefficient:

- The Leading Coefficient is defined as the number multiplying the variable with the highest degree or exponent.

- In the case of this question, the variable is "y".

- The y-variable with the highest power is "y⁵", thus, the Leading coefficient is the number multiplying "y⁵". In this case, that number is 12.

- Thus, the Leading Coefficient is 12

Degree of the Polynomial:

- The degree of a polynomial is the highest power of the variable in the polynomial.

- This variable with the highest number is usually multiplying the Leading Coefficient.

- Thus, the Degree of the Polynomial is 5.

Final Answer

- The Leading Coefficient is 12.

- The Degree of the Polynomial is 5.

To demonstrate that the diagonal slopes are opposing reciprocals, use the slope formula from coordinate geometry.

What is coordinate geometry?

The science of geometry using coordinate points is known as coordinate geometry (also known as analytical geometry).

Finding the difference between two points, breaking lines into m:n segments, locating a line's midpoint, computing a triangle's area in the Cartesian plane, and other operations are all feasible using coordinate geometry.

m=(rise/run) = (y2-y1)/(x2-x1)

(x1,y1) =  coordinates of the line's first point

The distance between the points (−3, −5) and (−3, −7) is 2 units.

The distance formula gives the shortest distance between two points in a two-dimensional plane.

The distance formula is a useful tool for calculating the distance between two points.

Therefore,

d = √(x₂ - x₁)²+(y₂ - y₁)²

Let's find the distance between the points (−3, −5) and (−3, −7).

Hence,

x₁ = -3

x₂ = -3

y₁ = -5

y₂ = -7

d = √(-3 + 3)² + (-7 + 5)²

d = √(-2)²

d = √4

d = 2

The total cost of a Jacket is $124.75 and the cost of pair of sneaker is $74.75.

Let us say that the cost of the pair of sneakers is X dollars.

According to the given situation,

Cost of One jacket is 50 dollars more than the cost of a pair of sneakers.

Cost of one jacket = $(50 + X).

Total cost of one jacket and one pair of sneakers is $200.

Total cost of jacket and sneakers = $200

We get,

X + (X+50.5) = 200

2X + 50.5 = 200

The above equation that we have got is linear equation in one variable because it has degree 1 and one 1 variable.

Further solving the equation,

2X + 50.5 = 200

2X = 149.5

X = 74.75

So, the cost of one pair of sneakers is $74.75

Cost of One jacket is $(X + 50.5).

Cost of one jacket = $124.75.

So, one jacket costs $124.75 and sneakers cost $74.75.

The probability that the customer came for lunch or did not order dessert is 93/113

It is the chance of an event to occur from a number of possible outcomes.

The angles that form a linear pair involving point F are:

a. ∠DFC and ∠CFG

d. ∠HFD and ∠CFD

A linear pair can be defined as the set of two angles that are adjacent to each other and share a common vertex and a common side, and also lie on a straight line.

Given the image in the question above, we see that:

Angle DFC and angle CFG share a common side FC and a common vertex point F, hence, they are adjacent angles that lie on a straight line, thus, they are a linear pair.

Angle HFD and angle CFD also share a common side FD and a common vertex point F. This makes them adjacent to each other. Also they are on a straight line. Therefore, angle HFD and angle CFD are a linear pair.

Thus, we can conclude that the angles that form a pair of angles that are classified as a linear pair are:
