When a coordinate grid is superimposed on a map of lanesville the middle school is located at (15,13) and the librart is located at (27,9). If each unit represents 1 mile how many miles apart are the middle school in the liebrary round your answer to the nearest 10th
Answer:
4.5 miles
Step-by-step explanation:
Given
[tex]Middle\ School = (15,13)[/tex]
[tex]Library = (27,9)[/tex]
To solve this, we simply solve for the distance (D) between both points.
[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Where:
[tex](x_1,y_1) = (15,13)[/tex]
[tex](x_2,y_2) = (27,9)[/tex]
[tex]D = \sqrt{(27 - 25)^2 + (9 - 13)^2}[/tex]
[tex]D = \sqrt{(2)^2 + (-4)^2}[/tex]
[tex]D = \sqrt{4 + 16}[/tex]
[tex]D = \sqrt{20}[/tex]
[tex]D=4.472135955[/tex]
[tex]D=4.5[/tex] --- approximated
Since each unit is 1 mile. The distance is 4.5 miles
Given AABC ADEF, AB = 4x-1, FD = 7, and DE = 8x-33.

Compare 2 4/5 ? 2.325
Answer:
>
Step-by-step explanation:
2.8>2.325
answer: > p l e a s e m a r k b r a i n l e s t .
this is because 2 4/5 = 2.800 and 2.800 is bigger than 2.325 because in the tenths place column (the column closest to the decimal without going over it), 8 is bigger than 3 so 2.800 is bigger than 2.325. So the answer is 2 4/5 > 2.325.

Which of the following regular polygons circumscribed about a circle provides the best estimate for the area of that circle?
dodecagon
decagon
20-gon
11-gon
Answer:
The correct option is;
20-gon
Step-by-step explanation:
The area, A, of a regular polygon is given as follows;
[tex]A = \dfrac{n \times s \times a}{2} = \dfrac{P_p \times a}{2}[/tex]
Where;
n = The number of sides
s = The length of one side of the polygon
a = The apothem
[tex]P_p[/tex] = The perimeter of the polygon
Where
The area of a circle, A[tex]_c[/tex] = π×r² = π × r × r = 2× π × r × r/2 = P/2 × r
Given that the apothem, a, of a 20-gon circumscribed about a circle is approximately the length of the radius of the circle, and the perimeter of the 20-gon is approximately the perimeter (circumference) of the circle, the area of the 20-gon circumscribed about a circle provides the best estimate for the area of the circle.

An apartment has 1026 square feet of carpeting.how much is this in square meters? Use the following conversion:1 square meters is 10.8 square feet
Answer:
95
because what is 95 times 10.8 if you multiply that you will get 1026
Also you get 95 by dividing 1026 by 10.8

Step-by-step explanation:
Since f(x) = 4[tex]x^{2}[/tex] + [tex]x^{4}[/tex] and g(x) = [tex]\sqrt (x^{2}+4)[/tex],
(f g) (x) = f( x ) * g( x ) = ( 4[tex]x^{2}[/tex] + [tex]x^{4}[/tex]) ( [tex]x^{2}[/tex] +4 )^(1/2)

1. a Classmate wrote the solution to the inequality |-4x+1|>3.
2. a classmate wrote the evolution to the equation |x-2|=4x+4.
Answer:
x>1 negative
x<(-1/2) positive
Step-by-step explanation:
Rearrange this Absolute Value Inequality
Absolute value inequalitiy entered
|-4x+1| > 3
Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |-4x+1|
For the Negative case we'll use -(-4x+1)
Solve the Negative Case
-(-4x+1) > 3
Multiply
4x-1 > 3
Rearrange and Add up
4x > 4
Divide both sides by 4
x > 1 for the negative
For the Positive case we'll use (-4x+1)
(-4x+1) > 3
Rearrange and Add up
-4x > 2
Divide both sides by 4
-x > (1/2)
Multiply both sides by (-1)
Remember to flip the inequality sign
x < -(1/2)
Which is the solution for the Positive Case
Answer for Q.2:
x=-2/5 negative
x=-2 poisitive
Explanation:
Rearrange this Absolute Value Equation
Absolute value equalitiy entered
|x-2| = 4x+4
STEP
2
:
Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |x-2|
For the Negative case we'll use -(x-2)
For the Positive case we'll use (x-2)
STEP
3
:
Solve the Negative Case
-(x-2) = 4x+4
Multiply
-x+2 = 4x+4
Rearrange and Add up
-5x = 2
Divide both sides by 5
-x = (2/5)
Multiply both sides by (-1)
x = -(2/5)
Which is the solution for the Negative Case
(x-2) = 4x+4
Rearrange and Add up
-3x = 6
Divide both sides by 3
-x = 2
Multiply both sides by (-1)
x = -2
Which is the solution for the Positive Case
