The perimeter of a shape is the sum of all visible side lengths of the shape. The perimeter of polygon qrst is 16 units.

Given that:

[tex]q = (-3,2)[/tex]

[tex]r = (1,2)[/tex]

[tex]s = (1,-2)[/tex]

[tex]t = (-3,-2)[/tex]

First, we calculate the distance between the vertices using distance formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

So, we have:

[tex]qr = \sqrt{(-3- 1)^2 + (2 - 2)^2} = \sqrt{16} = 4[/tex]

[tex]rs = \sqrt{(1- 1)^2 + (2 - -2)^2} = \sqrt{16} = 4[/tex]

[tex]st = \sqrt{(1--3)^2 + (-2 - -2)^2} = \sqrt{16} = 4[/tex]

[tex]tq = \sqrt{(-3--3)^2 + (-2 -2)^2} = \sqrt{16} = 4[/tex]

The perimeter (P) is the sum of all sides:

[tex]P = qr + rs + st + tq[/tex]

[tex]P = 4 + 4 + 4 + 4[/tex]

[tex]P = 16[/tex]

Hence, the perimeter is 16 units.

The question requires matching verbal descriptions of numbers with their corresponding numeric representations using decimal notation. The place value of each digit is used to determine the correct numeric form of the verbal description.

When matching the verbal descriptions to the correct number sentences, you will use the value of each place within a number to write it in decimal notation. For example, in the number 1837, the digit 7 is in the ones place (10⁰ = 1), the digit 3 is in the tens place (10¹ = 10), the digit 8 is in the hundreds place (10² = 100), and the digit 1 is in the thousands place (10³ = 1000). This helps us correctly identify the number sentences.

Number of units purchased = 117

Amount paid to purchase 117 units = $ 1250

Selling price of 117 units = $ 1601

Here, let us assume that all the units were sold at the same price.

So, profit on 117 units = [tex]1601-1250= 351[/tex]

Now, profit per unit will be,

[tex]\frac{351}{117} =3[/tex]

Hence, the profit earned per unit is $3.

The fourth graph represents the function.

We have to rewrite the given function into the standard form of a parabola.

A parabola is a U-shaped plane curve that is symmetrical about its vertex.

The standard form of a parabola is given by:

y = (x-h)²+k

Where (h,k) is the vertex of the parabola.

f(x) = x²+2x-1

We can rewrite this as:

f(x) = x²+2x+1-2

f(x) =( x+1)²-2

Now compare this with the given graphs. The only graph that has its vertex at (-1,-2) is the fourth graph.

We have found the graph that represents the function f(x) = x²+2x-1 to be the fourth graph.

If the two equations intersect at [tex](50,60)[/tex] then this point must satisfy the two equations.

[tex]3x+2y=270---(1)[/tex]

We substitute  [tex](50,60)[/tex]  in to erquation (1)

[tex]3(50)+2(60)=270[/tex]

[tex]150+120=270[/tex]

[tex]270=270[/tex]

[tex]y=\frac{4}{5}x+20 ---(2)[/tex]

We now substitute  [tex](50,60)[/tex]  in to erquation (2) also

[tex]60=\frac{4}{5}(50)+20[/tex]

[tex]60=40+20[/tex]

[tex]60=60[/tex]

Since the point satisfy all the two equations, it is true that they intersect at [tex](60,50)[/tex]

divide 3,326 by 3 and if she gets 842 it should be reasonable

Answer:

No her answer is not reasonable.  If you round 842 to 850 and multiplied that by 3 you would get 2,550.  

Step-by-step explanation:

Problem 1

Plug in x = 0 and solve for y to get the y intercept

6x+12y = 60

6(0)+12y = 60

12y = 60

12y/12 = 60/12 ... divide both sides by 12

y = 5

Answer: A) 5

======================================

Problem 2

Use the slope formula.

The two points are (x,1, y1) = (1, -1) and (x2, y2) = (-2, 8)

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

m = (8-(-1))/(-2-1)

m = (8+1)/(-2-1)

m = 9/(-3)

m = -3

Answer: A) -3

Answer:

Measure of ∠P = 60°

Step-by-step explanation:

Consider triangle PMO.

Since PM is perpendicular to MO , hence m∠PMO = 90°

Also given that m∠MOP = m∠2 = 30°

And since sum of three angles of a triangle is 180°

⇒ m∠PMO + m∠MOP + m∠MPO = 180°

⇒m∠MPO = 180° - (m∠PMO + m∠MOP) = 180° - ( 90 + 30 ) = 60°

Hence m∠MPO that is m∠P is 60°

Answer:

m 2 = 30°, m P = 60

The correct choice is 60

Whole numbers are a subset of integers, which in turn are a subset of rational numbers.

So, every whole number is an integer, and every integer is a rational number.

So, it is possible for a rational number not to be an integer. Think of any decimal number: 1.356 is a rational number, but it's not an integer.

On the other hand, if a number is not an integer, it can't be a whole number, because all whole numbers are integers.

First, combine like terms

-7x - 3x = -10x

-10x + 2 = -8x - 8

Isolate the x. Add 8x to both sides, and subtract 2 from both sides

-10x (+8x) + 2 (-2) = -8x (+8x) - 8 (-2)

-10x + 8x = -8 - 2

Simplify. Combine like terms

-2x = -10

Isolate the x. Divide 2 from both sides

(-2x)/-2 = (-10)/-2

x = -10/-2

x = 5

Answer:

Value of house in 2017  = 231525$

Explanation:

 At the start of 2014 worth of Lucy's house = 200000$

 Rate of increase of the value of the house = 5% = 0.05

 Value of house in 2015 = 200000+0.05*200000 = 210000$

 Value of house in 2016 = 210000+0.05*210000 = 220500$

 Value of house in 2017 = 220500+0.05*220500 = 231525$

 Number of years in between 2014 and 2017 = 2017 - 2014 = 3 years.

 Value of house in 2017 [tex]=200000*1.05^3=231525$[/tex]

13,501 rounded to the nearest ten thousand is 14,000. This is because if you look at the 3, the number next to it is 5, causing it to round up. Numbers 0-4 are rounded down, and numbers 5-9 are rounded up.

Answer:

10,000

Step-by-step explanation:

When we round a number to the nearest ten thousand we check the digit at the thousand place,

If the digit ≥ 5,

The number is rounded to next ten thousand,

If the digit < 5,

The number is rounded to previous ten thousand.

Here, the given number,

13,501,

Digit at thousand place = 3 ( < 5 )

Thus, 13,501 ≈ 10,000 ( nearest ten thousand )

Answer:

Average change in temperature is - 2.8 Fahrenheit per hour.

Step-by-step explanation:

Average change in temperature is the change in temperature divided by the time taken for the change.

Change in temperature = (-11.2) F- 0 F

                                       = -11.2 F

Time taken for the change in temperature = 10 pm - 6 pm

                                                                       = 4 hours

Average change in temperature = Change in temperature / time taken for the change

                                                      = [tex]\frac{-11.2}{4}[/tex]

                                                      = - 2.8 Fahrenheit per hour

Final answer:

The average change in temperature per hour from 6 pm to 10 pm is calculated by dividing the total change in temperature by the number of hours. The result is a drop of -2.8°F per hour.

Explanation:

To find the average change in temperature per hour between 6 pm and 10 pm, you can use the following expression:

(Final Temperature - Initial Temperature) / Number of Hours = Average Change per Hour

Applying the given temperatures:

(-11.2°F - 0°F) / (10 pm - 6 pm) = Average Change per Hour

Since 10 pm is 4 hours after 6 pm, the expression simplifies to:

(-11.2°F - 0°F) / 4 hours = Average Change per Hour

Which evaluates to:

(-11.2°F / 4) = -2.8°F per hour

So the temperature dropped on average by -2.8°F each hour between 6 pm and 10 pm.
