Given,
Side of the octagon = ( 2a + 1 ) units» Perimeter means total length of its boundary.
→ Octagon has 8 sides.
So,
→ Perimeter of Octagon = Length of 8 sides
→ Perimeter of Octagon = 8 ( 2a + 1 ) units
→ Perimeter of Octagon = 16a + 8 units
Therefore,
Perimeter of the octagon is [tex] \bf 16a + 8 [/tex] units.Step-by-step explanation:
Side of the octagon
An octagon has 8 sides. Each side is 2a + 1 units.
8(2a + 1)
= 16a + 8

The sixth grade art students are making a mosaic using tiles in shapes of right triangles. Each tiles has the leg measures of 5.2 cm and 6 cm. If there are 150 tiles in the mosaic, what is the area of the mosaic?
Given:
Each right triangular tiles has the leg measures of 5.2 cm and 6 cm.
There are 150 tiles in the mosaic.
To find:
The area of the mosaic.
Solution:
We know that, the area of a triangle is:
[tex]A=\dfrac{1}{2}\times Base\times height[/tex]
So, the area of Each right triangular tile is:
[tex]A=\dfrac{1}{2}\times 5.2\times 6[/tex]
[tex]A=\dfrac{1}{2}\times 31.2[/tex]
[tex]A=15.6[/tex]
There are 150 tiles in the mosaic. So, the area of the mosaic is:
[tex]Area=15.6\times 150[/tex]
[tex]Area=2340[/tex]
Therefore, the total area of the mosaic is 2340 cm ².

Ashley has X dollar. she spends $23.5 On a new top. She decides to keep 2/5 of what she has left, which is $13.80. how many dollars did Ashley have originally ?
Answer:
Total= X
Top= $23.5
Left= x-23.5
Saves= 2/5 * (x-23.5) = $13.80
0.4 * (x-23.5) = 13.80
X - 23.5 = 13.80/0.4
X - 23.5 =34.5
X= 34.5 + 23.5
=$58.00

The owners of the Syfy channel are interested in whether watching the Syfy channel causes people to become geeky, and whether any such effects depend on a person's gender. They hire a researcher to design and carry out the appropriate study. The researcher asks an equal number of men and women to watch 0, 3, 5, and 9 hours of the Syfy channel each week for 6 weeks. At the end of each week, the researcher measures the geekiness of the men and women on a scale from 1 to 10. How many cells are in this design
Answer:
The number of cells in this design = 4
Step-by-step explanation:
The number of cells in this design are four ( 4 ) and they are
The watchers can be equally geeky regardless of the hours watchedThe watchers can differ in geekiness level across the number of hours watched Women and Men may differ in geekiness levelsMen are geekier than women when watching few hours but less geekier than women when they watch more hours. and Vice versaGEOMETRY HELP PLEASE!!

Which graph represents a function with direct variation?
-5s=−13
solve for s .
Answer:
The answer is going to be 13/5 or 2.6
Step-by-step explanation:
You are going to need to divide both sides by the constant of -5 in order to get s by itsef. After you divide both sides by -5, you will get -13/-5 which two negatives divided by a positive so it would be 13/5 or if you turn it into an integer, it would be 2.6

Answer:
4y^3 + 4x^2 - 2
Step-by-step explanation:
Sort out these terms following powers of x and y:
First, y terms:
6y^3 - 2y^3 => 4y^3
Next, constants:
7 - 7 - 2 => -2
Next, x^2 terms:
6x^2 - 2x^2 => 4x^2
Now write out the modified expression, using the "combined terms" results given above:
4y^3 + 4x^2 - 2

Solve for p. −4.5 + p6= −18.9
Answer:
-2.4
Step-by-step explanation:
Given data
We have the expression before us as
−4.5 + p6= −18.9
Collect like terms
p6= −18.9+4.5
p6= -14.4
Divide both sides by 6
p= -14.4/6
p=-2.4
Hence the value of p= -2.4

On a coordinate plane, parallelogram R S T U has points (negative 4, 4), (2, 6), (6, 2), and (0, 0). What is the area of parallelogram RSTU? 24 square units 26 square units 32 square units 38 square units
Answer:
The area of the parallelogram is;
32 square units
Step-by-step explanation:
The given parameters are;
The coordinates of the parallelogram RSTU = R(-4, 4), S(2, 6), T(6, 2), and U(0, 0)
We note that the area of a parallelogram = Base length × Height
From the drawing of the parallelogram RSTU, we have;
The base length = The length of [tex]\overline {TU}[/tex] = The length of [tex]\overline {SR}[/tex] = √((2 - (-4))² + (6 - 4)²) = 2·√10
The height of a parallelogram is perpendicular to its base length = The line [tex]\overline {VT}[/tex]
∴ Where, the slope of the base length = m, the slope of the height = -1/m
The slope, 'm' of [tex]\overline {SR}[/tex] = (6 - 4)/(2 - (-4)) = 1/3
Therefore, the slope of the height = -1/(1/3) = -3
We note that a point on the height is the point 'T', therefore, the equation of the line in point and slope form is therefore;
y - 0 = -3·(x - 0)
∴ y = -3·x
Therefore, the coordinates of the point 'V' is given by the simultaneous solution of the equations of [tex]\overline {SR}[/tex] and [tex]\overline {VT}[/tex]
The equation of the line [tex]\overline {SR}[/tex] in point and slope form from the point 'R' and the slope 'm = 1/3' is given as follows;
y - 4 = (1/3) × (x - (-4)) = (1/3) × (x + 4)
y = x/3 + 4/3 + 4 = x/3 + 16/3
y = x/3 + 16/3
We then have the coordinate at the point 'V' (x, y) is given as follows;
-3·x = x/3 + 16/3
-9·x = x + 16
-10·x = 16
x = -16/10 = -1.6
x = -1.6
∴ y = -3·x = -3 × -1.6 = -4.8
y = 4.8
The coordinate at the point, V = (-1.6, 4.8)
The length of the line [tex]\overline {VT}[/tex] = The height of the parallelogram = √((-1.6 - 0)² + (4.8 - 0)²) = 8/5·√10
The height of the parallelogram = 8/5·√10
The area of the parallelogram, A = Base length × Height
∴ A = 2·√(10) × 8/5·√(10) = (16/5) × 10 = 32
The area of the parallelogram, A = 32 square units.
Answer:
Im pretty sure its 32
