Based on the given parameters about a carpenter cutting the top section of a window frame, the side pieces of the frame are not parallel.

Parallel lines are lines which are equally distant from one another at all points.

To show that the side pieces of the frame are parallel:

The interior angles are equal in measure and the sum of the interior angles must be equal to 180°

The two given side pieces of the window frame are also equal in measure.

If the sum of both side angles is equal to 180∘, then, the sides are parallel.

37∘ + 50∘ = 87∘

2(37∘ + 50∘)

= 2(87∘)

= 174∘

Hence,

174∘ < 180∘

So therefore, the sides pieces of the window frame cut by the carpenter are not parallel.

The inequality of the scenario is 10000 ≤ l² - 16l < 16000 and the length is 1672 feet

The statements from the question are given as:

Shape = Rectangular park

Minimum perimeter = 5000 square ft

Maximum perimeter = Less than 8000 square ft

Also, we have

Width = 8 less than half the length

This means that

w = 1/2l - 8

The perimeter of a rectangle is

perimeter = 2 * (l + w)

So, we have

P = lw

This gives

P = 2 * (l + 1/2l - 8)

P = 2 * (1.5l - 8)

Open the brackets

P = 3l - 16

Substitute the known values in the above equation So, we have the following equation

5000 ≤ 3l - 16 < 8000

The above represents the inequality

See attachment for the graph

From the graph, we have the solution to be

l = 1672 (approximately)

Recall that:

w = 1/2l - 8

So, we have

w = 1/2 * 1672 - 8

Evaluate

w = 828

Hence, the possible length is 1672 ft

The polynomial of p(x) is  -24 (x² + 15x + 54) with the satisfying's conditions degree 3.

Given,

An nth degree polynomial p meets the requirements listed below:

p is of degree 3.

-9 is a zero, with multiplicity 2, of p.

-6 is a zero, with multiplicity 1, of p.

p(-1) = -960

We have to determine an nth degree polynomial that satisfier the conditions.

Let the polynomial be p(x) whose zero are -9 and -6

a be the coefficient.

p(x) = a (x+9) (x+6)

p(x) = a(x² + 6x + 9x + 54)

p(x) = a(x² + 15x + 54)

Now, take x = -1

p(-1) = a (-1² + 15 x -1 + 54)

-960 = a ( 1 - 15 + 54)

-960 = a x 40

a = -960/40

a = -24

We get,

p(x) = -24 (x+9) (x+6)

p(x)= -24 (x² + 15x + 54)

Therefore, the polynomial of p(x) is  -24 (x² + 15x + 54) with the satisfying's conditions degree 3.

The amount of the monthly payments is $368.34, and the total interest on the loan is $5,100.

The initial amount of money that we borrow is $17,000. We borrow this amount for a total of five years. The interest charged is 6%. We borrowed the money for the purchase of a car. We need to find the monthly payments and the total interest for the loan.

Let the total amount to be paid and the interest be denoted by the variables "A" and "I", respectively.

I = P*R*T

I = $17,000*0.06*5

I = $5,100

The total amount of money to be paid is the sum of the initial amount and the interest charged.

A = P + I

A = $17,000 + $5,100

A = $22,100

The total number of months in five years is 12*5 = 60.

The amount of the monthly payment is the ratio of the total amount to be paid to the total number of months.

The cost of the sweater is $ 30 and

1 dollar = 17 pesos, $ 25 = 425 pesos and $ 3 dollar = 51 pesos.

Mathematical Operations are activities or mathematical processes used to solve given problems. The most used mathematical activities are adding, subtracting, multiplying, and dividing.

The basic operations and their symbols are given below
Addition (+); Subtraction (-); Division (÷);  and Multiplication (x).  

Here we have

Priya exchanged 250 dollars for 4250 pesos  

[Here we used division and multiplication to solve the problem ]

Then the value of 1 dollar in pesos = [tex]\frac{4250}{250}[/tex] = 17 pesos

⇒ 1 dollar = 17 pesos

⇒ 25 dollars = 25 × 17 = 425 pesos

⇒ 3 dollar = 3 × 17 = 51 pesos

Given the cost of the sweater = 510 pesos  

The cost of the sweater in pesos = [tex]\frac{250}{4250} \times510[/tex] = 30

The gallons of water and premium antifreeze solution that must be mixed are equal to 60 gallons and 120 gallons respectively.

In order to calculate the gallons of water and premium antifreeze solution, we would assign variables to the gallons of water and premium 60% antifreeze that is required, and then translate the word problem into algebraic equation as follows:

Since the premium antifreeze solution contains 60% premium antifreeze, we have the following mathematical expression:

x + y = 180      ....equation 1.

0.60y = 0.40(180)    ....equation 2.

From equation 2, we have:

0.60y = 0.40(180)

0.60y = 72

y = 72/0.60

y = 120 gallons of premium antifreeze.

For the gallons of water, we have the following:

x + y = 180

x = 180 - y

x = 180 - 120

x = 60 gallons of water.

Kinetic energy is defined as the work required to accelerate a body of a given mass from rest to its stated speed. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Mass - (Measured in Kilogram) - Mass is the amount of matter in a body, regardless of its volume or the forces acting on it.

Velocity - (Measured in Meters per Second) - Velocity is a vector quantity (has both magnitude and direction) and is the rate of change of an object's position with respect to time.

We have that the data is:

The formula to calculate kinetic energy is:

             Ec = m * v²/2

Since it only asks us to calculate the kinetic energy, it is not necessary to clear the formula.

[tex]\boldsymbol{\sf{Ec=\dfrac{158 \ kg*\left(0.42 \ \frac{m}{s}\right)^2 }{2} }}[/tex]

The probability that Rebecca's first flight was delayed is 75%.

Probability is the ratio or odds of an expected outcome occurring when there are many possible outcomes.

Probability is always a fractional value lying between 0 and 1.  When the expected outcome is certain, the probability is said to be one.  When it is uncertain, the probability is zero.

Like ratios, probability is depicted as decimals, fractions, or percentages when there is no 100% certainty or uncertainty.

The probability of Rebecca's first flight leaving on time = 0.25

The probability of Rebecca's first flight being delayed = 0.75 (1 - 0.25)
