The _____ ratio is the ratio of the length of one side of a polygon with the length of a corresponding side of a similar polygon.
The scale ratio is the ratio of the length of one side of a polygon with the length of a corresponding side of a similar polygon.
The ratio you're referring to is called the scale factor. The scale factor is the ratio of the length of one side of a polygon to the length of the corresponding side of a similar polygon. Let's denote this scale factor as ( k ).
To calculate the scale factor, you need to choose corresponding sides from the two similar polygons. Once you've chosen a pair of corresponding sides, divide the length of one side by the length of the corresponding side from the other polygon.
Let's say we have two similar polygons, Polygon A and Polygon B, and we want to find the scale factor between them. Let's denote the length of a side of Polygon A as [tex]\( L_A \)[/tex] and the length of the corresponding side of Polygon B as [tex]\( L_B \)[/tex]. Then, the scale factor, ( k ), is given by:
[tex]\[ k = \frac{L_A}{L_B} \][/tex]
This ratio will give you the scale factor between the two polygons.

Find the square root of the fraction 64/100
Assembly Line A produces 45 units in the same time that it takes Assembly Line B to produce 37 units. If Line B produces 555 units, how many units does Line A produce during the same time?
Assembly Line A will produce 24975 units during the same time that Line B produces 555 units.
Explanation:Let's assume that the time it takes for Assembly Line A to produce 45 units is equal to the time it takes for Assembly Line B to produce 37 units. This means that the time it takes for Line A to produce 1 unit is equal to the time it takes for Line B to produce 1 unit.
Now, we can set up a proportion to find how many units Line A will produce during the same time that Line B produces 555 units:
45 units / 1 unit = x units / 555 units
Cross-multiplying, we get:
45 * 555 = x units * 1
x units = 24975 units
Therefore, Line A will produce 24975 units during the same time that Line B produces 555 units.

Which set represents the range of the function shown?
{(-1,5),(2,8),(5,3),(13,-4)}
A- {-1,2,5,13}
B-{-4,3,5,8}
C- {(5,-1),(8,2),(3,5),(-4,13)}
D-{-4,-1,2,3,5,5,8,13}
Answer:
B. {-4,3,5,8}
Step-by-step explanation:
We are given,
The set representing the function is {(-1,5),(2,8),(5,3),(13,-4)}.
It is required to find the range set of the function.
Now, as we know,
In the ordered pair [tex](x,y)[/tex], the y co-ordinate 'y' represents the range values of a function.
So, we see that,
The range values of the given function are 5, 8, 3 and -4.
Thus, the set representing the range of the function is {-4,3,5,8}.
There are 5,280 feet in 1 mile. If Riley ran 26,400 feet, how many miles did she run? [Type your answer as a number.]
Answer:
She ran 5 miles
Step-by-step explanation:
To solve this, we can easily use proportion.
The question state that there are 5,280 feet in a mile, We are ask to find the number of miles Rily run, if she ran 26,400 feet.
Using proportion;
Let x = the number of miles Rily can run
5,280 feet = 1 mile
26,400 feet = x
Cross-multiply
5280x = 26,400
To get the value of x, we will divide both-side of the equation by 5280
5280x/5280 = 26400/5280
(On the left-hand side of the equation, 5280 will cancel-out 5280 leaving us with x and on the right-hand side of the equation 26400 will divide 5280)
x = 26400 / 5280
x=5 mile
Therefore, If Rily ran 26400 feet, then she has ran 5 miles.
How many watches must he repair to have the lowest cost?
ruby is visiting San Francisco. From her hotel she walks 1 block west ans 4 blocks south to a coffee shop. Then she walks 5 blocks east and 6 blocks south to a museum. Where is the museum in relation to her hotel
Answer:
The museum is 4 blocks east and 10 blocks south from her hotel.
Step-by-step explanation:
It is given that ruby is visiting San Francisco. From her hotel she walks:
(a) 1 block west and 4 blocks south to a coffee shop.
(b) Then she walks 5 blocks east and 6 blocks south to a museum.
First she moves 1 block west and 4 blocks south and reached at point B. After that she walks 5 blocks east and 6 blocks south and reached at point D.
From the below figure it is noticed that point D is 4 blocks east and 10 blocks south from the origin because
[tex]South=4+6=10[/tex]
[tex]East=5-1=4[/tex]
Therefore the museum is 4 blocks east and 10 blocks south from her hotel.

The table shows the number of minutes Jalen talks on his mobile phone and the cost of the phone calls. Jalen’s Mobile Phone Cost Number of minutes, x 150 220 250 275 Cost, y $7.50 $11.00 $12.50 $13.75 If the cost varies directly with the number of minutes Jalen talks on the phone, which equation represents the variation?
Answer:
[tex]y=0.05x[/tex]
Step-by-step explanation:
Given :
x Cost, y
150 $7.50
220 $11.00
250 $12.50
275 $13.75
To Find: If the cost varies directly with the number of minutes Jalen talks on the phone, which equation represents the variation?
Solution:
To find equation we will use two point slope form.
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex](x_1,y_1)=(150,7.50)[/tex]
[tex](x_2,y_2)=(220,11.00)[/tex]
Substitute the values in the formula.
[tex]y-7.50=\frac{11-7.5}{220-150}(x-150)[/tex]
[tex]y-7.50=0.05(x-150)[/tex]
[tex]y-7.50=0.05x-7.50[/tex]
[tex]y=0.05x[/tex]
Hence the equation which represents the variation is [tex]y=0.05x[/tex]

Answer:
[tex]10x^4+65x^3-25x^2[/tex]
Step-by-step explanation:
Multiply 5x^2(2x^2 + 13x − 5)
[tex]5x^2(2x^2 + 13x - 5)[/tex]
Multiply 5x^2 inside the parenthesis
[tex]5x^2 * 2x^2 = 10x^4[/tex]
[tex]5x^2 * 13x = 65x^3[/tex]
[tex]5x^2 * (-5) = -25x^2[/tex]
Collect all the terms together

What is the image of (5,-1) under same translation?
The image of point (5, -1) under the same translation that maps point P to P' is (1, -8). This translation vector is obtained by subtracting the coordinates of P from P'.
To find the image of point (5, -1) under the same translation T that maps point P to P', we can calculate the vector that represents the translation from P to P' and then apply the same translation to point (5, -1).
The translation vector is given by:
Translation vector = P' - P = (-6, -4) - (-2, 3) = (-4, -7)
Now, to find the image of point (5, -1) under the same translation, we simply add this translation vector to (5, -1):
Image of (5, -1) = (5, -1) + (-4, -7) = (5 - 4, -1 - 7) = (1, -8)
So, the image of point (5, -1) under the translation T is (1, -8). Therefore, the correct answer is B. (1, -8).

Find the value of m angle 3-m<1
Answer:
The value of [tex]m\angle 3-m\angle 1[/tex] = [tex]50^{\circ}[/tex]
Step-by-step explanation:
Vertical Angle theorem: It is about the angles that are opposite to each other.
Also, vertical angle are congruent that means vertical angles are equal.
In the given figure; [tex]m\angle 3[/tex] and [tex]70^{\circ}[/tex] are vertical angle
then, by vertical angle theorem, [tex]m\angle3 =70^{\circ}[/tex].
Supplementary angle: the sum of the angles whose measure on the straight line is 180 degree.
From the figure, [tex]70^{\circ}[/tex] , [tex]\angle 1[/tex] and [tex]m\angle 2 =90^{\circ}[/tex] forms a straight line.
then, by the definition of Supplementary angle;
[tex]70^{\circ}+m\angle 1 +m\angle 2=180^{\circ}[/tex]
Substituting the value of [tex]m\angle 2 =90^{\circ}[/tex] in above equation:
[tex]70^{\circ}+m\angle 1 + 90^{\circ} =180^{\circ}[/tex] or
[tex]160^{\circ}+m\angle 1=180^{\circ}[/tex]
Simplify:
[tex]m\angle 1=180^{\circ}-160^{\circ} =20^{\circ}[/tex]
therefore, [tex]m\angle 1= 20^{\circ}[/tex] and [tex]m\angle 3=70^{\circ}[/tex],
the value of [tex]m\angle3-m\angle1= 70^{\circ}-20^{\circ} =50^{\circ}[/tex].
