The first skater has a 40 meter d and is traveling at a rate of 12 meters second, second skater is traveling rate of 14 meters per second. it will take 20 seconds for second skater to pass the first skater.

Time is continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. It is component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in conscious experience. Time is often referred to as fourth dimension, along with three spatial dimensions.

Time has long been an important subject of study in religion, philosophy, and science, but defining it in manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and performing arts all incorporate some notion of time into their respective measuring systems.

The $7,834.54 borrowed at 18.6% annual interest rate with the landscape architect's monthly payment of $500, gives the number of months it will take to repay the debt as approximately 19 months

Monthly payment on a loan, is the amount the person who takes the loan, pays each month in order to settle the loan in a given time period.

The monthly payment formula is presented as follows;

[tex] \displaystyle{M = \frac{P \cdot \left( \frac{r}{12} \right) \cdot \left( 1 + \frac{r}{12} \right)^{n} }{\left( 1 + \frac{r}{12} \right)^{n} - 1} }[/tex]

Where;

M = The amount the landscape architect paid monthly = $500

P = The amount loaned or borrowed = $7,834.54

r = The interest per annum = 18.6%

n = The number of monthly payment made

Therefore;

[tex] \displaystyle{500 = \frac{7834.54 \cdot \left( \frac{0.186}{12} \right) \cdot \left( 1 + \frac{0.186}{12} \right)^{n} }{\left( 1 + \frac{0.186}{12} \right)^{n} - 1} }[/tex]

Evaluating the above equation gives;

[tex] \displaystyle{500 = \frac{121.43537.1 \cdot 1.0155^{n} }{1.0155^{n} - 1} }[/tex]

[tex] \displaystyle{500 \times (1.0155^{n} - 1) = 121.43537.1 \cdot 1.0155^{n} }[/tex]

[tex] \displaystyle{500 \times 1.0155^{n} - 121.43537.1 \cdot 1.0155^{n} ) = 500 }[/tex]

Which by taking natural logarithms of both sides gives;

n•ln(1.0155) = ln(1.32077843609)

n = ln(1.32077843609) ÷ ln(1.0155) ≈ 18.09

Rounding up to the nearest month gives;

The number of months it will take the architect to pay the debt is approximately 19 months

The maximum amount Cedar should pay for monthly rent is 13,500.

We need to know the maximum amount of monthly rent cost to solve this problem. In this country, the department of housing and urban development has ruled that the maximum monthly rent cost is 30% of gross profit.

Max cost = 30% Gross

From the question above, the given parameter is

Gross profit = 45,000

By substituting the given parameter, the maximum monthly rent cost is

Max cost = 30% Gross

Max cost = 30% x 45,000

Max cost = 13,500

Hence, the monthly rent cost should have a maximum amount of 13,500.

The equation of the line that passes through the graph is y + 2 = -3/2(x - 2)

The graph represents the given parameter

From the graph, the points are given as

(0, 1) and (2, -2)

Calculate the slope of the points using

Slope = (y₂ - y₁)/(x₂ - x₁)

Rewrite as

m = (y₂ - y₁)/(x₂ - x₁)

This means that

Slope = m

So, we have the following representation

m = (-2 - 1)/(2 - 0)

Evaluate

m = -3/2

The equation of the line is then calculated as

y = m(x - x₁) + y₁

Where

(x₁, y₁) = (2, -2)

m = -3/2

So, we have

y = -3/2(x - 2) - 2

Add 2 to both sides

y + 2 = -3/2(x - 2)

Hence, the equation of the line is y + 2 = -3/2(x - 2)

Answer:

1100

Step-by-step explanation:

783 rounded to the nearest hundred is 800

329 rounded to the nearest hundred is 300

800+300=1100

The estimation of 783 + 329 = 1100.

Although the term "rounding" is a general one, we typically use the terms "round up" or "round down" to indicate whether the number has gone up or down after being rounded. The supplied number is said to be rounded up when the rounded number is increased, and it is said to be rounded down when the rounded number is dropped.

Given:

783 + 329

Now rounding off nearest hundred

783 rounded off to 800

and, 329 rounded off to 300.

So, 800+ 300 = 1100

Hence, the estimation is 1100.

The ordered pairs in the solution set of the system of linear inequalities y ≥ -1/3x +2 and y < 2x + 3 are (2, 2), (3, 1), and (4, 2).

Given linear inequalities represented in the graph are:

y ≥ -1/3x +2

y < 2x + 3

In the graph, the shaded region above the solid line denotes the inequality,

y ≥ -1/3x +2

The shaded area on the right side of the dotted line denotes the inequality's solution set,

y < 2x + 3

And the common area of these inequalities will denote the solution set of the system of linear inequalities.

Ordered pairs are (2, 2), (3, 1), and (4, 2) and will therefore be located in the shared shaded area.

The condition for the figure to be similar is that; DE = FD

Similar figure are zoomed in or zoomed out (or just no zoom) version of each other. They are scaled version of each other, and by scale, we mean that each of their dimension(like height, width etc linear quantities) are constant multiple of their similar figure.

In the problem, the ratio should be CD/DE = GD/DF

We can also write the ratios of the corresponding sides as:

CD/DE = GD/DF

If area of sector = area of circle

r^2-4r-8 =0

A sector is a cut out section of a circle. It is of two radii and an arc .

The area of a sector is angle substended/ 360 x area of a circle

area of a circle is πr^2

if area of circle is equal to the area of sector

120/360×π(r+4)^2=πr^2

divide both side by π

1/3(r+4)^2=r^2

From SOH CAH TOA, we have that

sin (angle) = opposite / hypotenuse

cos (angle) = adjacent / hypotenuse

tan (angle) = opposite / adjacent

Considering angle A,

Opposite = 16

Adjacent = 12

Hypotenuse = 20
