Which ordered pairs are in the solution set of the system of linear inequalities y > -1/3x +2 y < 2x + 3
Answers
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).
What is the system of inequalities?One or more linear inequalities in each of the same two variables make up a system of linear inequalities in two variables. A linear inequality solution is an ordered pair that resolves all of the system's inequalities, and the inequality's graph is a representation of all of the system's solutions.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.

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.

Estimate the answer to 783 + 329 by rounding each number to the nearest hundred
Answers
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.
What is Rounding off?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

B y−4=−23(x+2)
C y+1=−23(x−3)
D y−3=32(x+1)
Answers
The equation of the line that passes through the graph is y + 2 = -3/2(x - 2)
How to determine the equation of the line?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)

A landscape architect accrued $7,834.54 in credit card debt. If the architect makes a monthly payment of $500 (and makes no additional charges on the account), how many months will it take to repay the debt if the annual interest rate on the credit card is 18.6%? (Round your answer up to the nearest month.)
Answers
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
What is a monthly payment?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

All lines add up to 180 degrees so you subtract the exterior angle, 132 degrees, by 180 to get the difference of 48 degrees in the interior angle. Also since the triangle is a right angle, you know the sum of the other two angles add up to 90 degrees. So 48 plus angle E would have to add up to 90 degrees. Therefore 48 degrees plus angle E, 42 degrees, adds up to 90 degrees.

Answers
The smallest drawing will be the one that has the smallest drawing unit with respect to the the actual unit.
We have:
A. 1 in to 1 ft
B. 1 in to 1 m
C. 1 in to 1 yd
If we put them all in meters, we have:
A. 1 in to 0.3048 m
B. 1 in to 1 m
C. 1 in to 1/1.1 = 0.90... meters
Then, the small drawing will be B, as 1 meter is the largest actual unit.
Second, will be B, that has 1 in by approximately 0.9 meters.
Third and last, option A, which drawing has an scale of 1 in in 0.3048 meters.
We can calculate the scale as a ratio between the drawing units and actual units, expressed in the same units.
For example, for A, we have:
[tex]\frac{1\text{ in}}{1\text{ ft}}\cdot(\frac{1\text{ ft}}{12\text{ in}})=\frac{1}{12}[/tex]So the scale is 1:12.
NOTE: look that we have cancelled all the units with this operation.
For B, we have:
[tex]\frac{1\text{ in}}{1\text{ m}}\cdot(\frac{2.54\text{ cm}}{1\text{ in}})\cdot(\frac{1\text{ m}}{100\text{ cm}})=\frac{2.54}{100}=\frac{254}{10000}[/tex]For C, we have:
[tex]\frac{1\text{ in}}{1\text{ yd}}\cdot(\frac{1\text{ yd}}{3\text{ ft}})\cdot(\frac{1\text{ ft}}{12\text{ in}})=\frac{1}{36}[/tex]You can verify that B has the smallest scale (0.0254)

Answers
The value for the volume of the room is 31. 84 cubic centimeters(cm³)
The mass of the air in the room is 41. 39 kg
How to determine the volume of the roomThe formula for calculating the volume of the room is expressed as;
Volume = l × w × h
Where;
l is the length of the roomw is the width of the roomh is the height of the roomFrom the information given, we have to substitute the values of the measurements of the room into the formula.
We have;
Volume, v = 4. 02 × 3. 37 × 2. 35
Volume, v = 31. 84 cubic centimeters(cm³)
To determine the mass of the air in the room, we use the formula for mass which is expressed as;
Mass = Density × volume
Given that;
Density of air = 1. 3kg/m³Volume of the room = 31. 84 cubic centimeters(cm³)Substitute the values
