There is a average of 50,000 spiders per acre in green areas, How many spiders would be in 1/4 of an acre?

Answer:

4x-3

Step-by-step explanation:

(7x-5) - (3x-2)

aka

(7x-5)  -1 (3x-2)

first distribute the -1 into (3x-2)

-3x+2

so

(7x-5)+ -3x+2

next combine like terms

7x-3x=4x

so

4x-5+2

then

-5+2=-3

so

4x-3 would be your simplified equation

Answer:

The question is written kinda bad, so i take the next two assumptions:

The original line is:

y = 5*x + 23

And we want to find a perpendicular line that passes through the point (-40, 2012)

Suppose that we have a linear equation:

y = a*x + b

A perpendicular line to this one, will have a slope equal to -(1/a)

Then a random perpendicular line to the one above, is:

y = -(1/a)*x + c

In this case, we start with the line:

y = 5*x + 23

Then the family of perpendicular lines to this one, will be like:

y = (-1/5)*x + c

Where c can be any real number.

Now, we also want this line to pass through (-40, 2012)

This means that when x = -40, the value of y must be 2012

We could replace these values in our equation above and solve it for c.

2012 = -(1/5)*(-40) + c

2012 = 40/5 + c

2012 = 8 + c

2012 - 8 = c = 2004

Then the equation is:

y = -(1/5)*x + 2004.

Answer:

c = 5

Step-by-step explanation:

13² - 12² = c²

169 - 144 = c²

√25 = c

5 = c

Answer:

180m

Step-by-step explanation:

Let L = length of field,

W = width of field,

A = field area = 2000 m^2

Lenght = Width + 10m

Let Lenght= x

Width=y

A = X ×Y = (Y + 10)Y= 2000

Y^2 + 10Y- 2000 = 0

Solving using Quadratic eqn with plot

Y= 40 or -50 but we go for the positive root

Width=40m

Length= 40m +10m

= 50m

Perimeter= 2(l+w)

=2(50+40)

180m

Hence, the perimeter is 180 m

Answer:

The unit rate for 65 miles in 2.7 gallons is 24.07 miles per gallon.

Step-by-step explanation:

Given that:  

65 miles in 2.7 gallons

We have to find the unit rate.

Unit rate is a rate to compare quantities in which one quantity is 1.

Unit rate = [tex]\frac{65}{2.7}[/tex]

Unit rate = 24.07 miles per gallon.

Hence,

The unit rate for 65 miles in 2.7 gallons is 24.07 miles per gallon.

Answer: 120 degrees

Step-by-step explanation: a circle always has a total of 360 degrees

Answer:

              y + 3= 3(x - 6)        ←    point-slope form

             y = 3x - 21           ←    slope-intercept form

             3x - y = 21         ←    standard form

Step-by-step explanation:

The point-slope form of the equation of line it's y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the point the line passing through.

y=m₁x+b₁   ║   y=m₂x+b₂   ⇔    m₁ = m₂

{Two lines are parallel if  their slopes are equal}

y = 3x + 1   ⇒    m₁ = 3    ⇒    m₂ = 3

(6, -3)    ⇒    x₁ = 6,  y₁ = -3

point-slope form:

y - (-3) = 3(x - 6)

y + 3 = 3(x - 6)

y + 3 = 3x - 18              {subtact 3 from both sides}

y = 3x - 21        ←    slope-intercept form

-3x + y = -21                 {multiply both sides by (-1)}

3x - y = 21         ←    standard form

Answer: Identity Property of Addition

Step-by-step explanation: The identity property holds true for addition.

The statement 20 + 0 = 20 represents the identity property of addition.

The identity property of addition says we add 0

to any number, the sum is equal to the original number.

In general terms, we can write the identity property of addition

as a + 0 = a where a is a variable that represents any number.

Answer: [tex]a_{10}[/tex] = -33

Step-by-step explanation:

-6, -9, -12, -15

The common difference is -3

d = common difference

Arithmetic sequence formula:

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n - 1) d

[tex]a_{10}[/tex] = -6 + (10 - 1) -3

[tex]a_{10}[/tex] = -6 + 9 × -3

[tex]a_{10}[/tex] = -6 - 27

[tex]a_{10}[/tex] = -33

Answer:

its -30

Step-by-step explanation:

because -15-15=-30

Answer:

Step-by-step explanation:

The total distance is 30.

According to MQ = 30 .

And the first distance is

MN which is 5

MN = 5

and NO is equal to MN

MN = NO

giving us MN + NO = 10 or 5 + 5 =10

so if we need 30 and have 2 points that equal to 10

we need 20 more to equal 30

leaving OP = PQ or 10 = 10

10+10+5+5= 30

MN + NO + OP + PQ = MQ

THE ANSWER IS 10

Answer:

B. r = A-p/pt

Step-by-step explanation:

We can rearrange the equation to make [tex]r[/tex] the subject of the equation:

[tex]A=p+prt[/tex]

[tex]A-p = p+prt-p[/tex]

[tex]A-p = prt[/tex]

[tex]\frac{A-p}{pt} = \frac{prt}{pt}[/tex]

[tex]r = \frac{A-p}{pt}[/tex]

∴ Option B is correct

Hope this helps :)

Answer:

D

Step-by-step explanation:

The unmarked angle of the triangle is also 40o. The triangle is marked with two equal sides (isosceles).

<2 + 40 + 40 = 180            Combine the left

<2 + 80 = 180                    Subtract 80 from both sides

<2 = 180 - 80

<2 = 100 degrees.

That's not the answer. We have to solve for x

<2 = x + 106

100 = x + 106       Subtract 106 from both sides

100 - 106 = x

x = - 6

Answer:

38

Step-by-step explanation:

All you have to do to find the perimeter of a 2D shape is to add the sides and put the unit of measurement at the end of your answer.

Perimeter of ABCD is 38 units.

From the picture attached,

Perimeter of the given parallelogram = AB + BC + CD + DA

                                                              = 9 + 10 + 9 + 10

                                                              = 38 units

     Therefore, perimeter of the given parallelogram will be 38 units.

Answer:

x = 20 degrees

Step-by-step explanation:

From the diagram shown, we are to find the value of

Since the adjacent side of the parallelogram on top are equal, hence their opposite angles are also equal

The third angle in the triangle below will be 180 - 60 = 120

Sum of angle in the triangle is 180 degrees, hence;

x + 2x + 120 = 180

3x = 180-120

3x = 60

x = 60/3

x = 20 degrees

Hence the value of x in the diagram is 20 degrees
