Given:
Point F,G,H are midpoints of the sides of the triangle CDE.
[tex]FG=9,GH=7,CD=24[/tex]
To find:
The perimeter of the triangle CDE.
Solution:
According to the triangle mid-segment theorem, the length of the mid-segment of a triangle is always half of the base of the triangle.
FG is mid-segment and DE is base. So, by using triangle mid-segment theorem, we get
[tex]\dfrac{1}{2}DE=FG[/tex]
[tex]DE=2(FG)[/tex]
[tex]DE=2(9)[/tex]
[tex]DE=18[/tex]
GH is mid-segment and CE is base. So, by using triangle mid-segment theorem, we get
[tex]\dfrac{1}{2}CE=GH[/tex]
[tex]CE=2(GH)[/tex]
[tex]CE=2(7)[/tex]
[tex]CE=14[/tex]
Now, the perimeter of the triangle CDE is:
[tex]Perimeter=CD+DE+CE[/tex]
[tex]Perimeter=24+18+14[/tex]
[tex]Perimeter=56[/tex]
Therefore, the perimeter of the triangle CDE is 56 units.

Isabel has ridden 16 miles of a bike course. The course is 80 miles long. What percentage of the course has Isabel ridden so far?
Answer:
20%
Step-by-step explanation:
Divide 16 by 80 and you get 0.2 as an answer and to get a percent you move the decimal 2 places to the right to fet 20%
Isabel has completed 20 percent of the race of 80 miles.
What is the percentage?A percentage is a quantity or ratio that, in mathematics, represents a portion of one hundred. It is one method for illustrating a relationship between two integers that has no dimensions.
Given, Isabel has ridden 16 miles of a bike course. The course is 80 miles long. From the general formula of percentage:
For the percentage, we have to divide the value by the total value and then multiply the result by 100.
percentage of the course has Isabel ridden so far = (16/80) * 100
percentage of the course has Isabel ridden so far = 1/5*100
percentage of the course has Isabel ridden so far = 20%
Therefore, Isabel has ridden 20 percent of the course which is 80 miles.

did i do this right “what % of 369 is 26” i got 7.04 so is that the rounded answer (hundredths place) or just 7.0=7?
Answer:
26 is 7.05% or 7.04% of 369.
Step-by-step explanation:
Now 7.04% of 369 is actually 25.9776.
and 7.04% is 26.01452.
But if you round both 25.9776 and 26.01452 you get 26
So, technically you are correct.

my day was okay. Had school, played some games, did hw, normal stuff. :D
Anywho im going to do my tutor hw and maybe help some other people. Bye!
Answer:
14 cm^2
Step-by-step explanation:
First of all we have to find the total area
total area = lenght x width = 8 x 2 = 16 cm^2
the shaded area is a right triangle
the area of a right triangle is
A = (leg 1 x leg2)/2 = (2 x 2)/2 = 2 cm^2
now we have to subtract it from the total area
16-2 = 14 cm^2

Answer:
7,13,37,55,103
Step-by-step explanation:
y = 5 + 2x^2
if x =1
y = 5 + 2(1)^2
1^2 = 1
2 x 1 = 2
y=5 + 2 or y = 7
you substatute each one in for x to solve for y
For the function a(-5) = -2, and a(-2) = -5. If y = a(x), what is the value of y when x = -2?
A resposta é -5, como diz na pergunta.

The floor tiles In the Jackson family kitchen are squares that measure 8 and 3/4 to a side. Each grid Square in the drawing measures 1/4 in to a side which is the scale of the drawing.
Answer:
Step-by-step explanation:
The aware iz 1 in 35 in
The scale of drawing is 1 inch : 27 inch
What is scale factor?The scale factor is a measure for similar figures, who look the same but have different scales or measures. The scale factor states the scale by which a figure is bigger or smaller than the original figure.
Given that, the measurement of the tile = 27/4 inches
Side of the drawing = 1/4 inches
The scale of the drawing =
1/4 inch of drawing = 27/4 inch of tile
That means, 1 inch of the drawing = 27 inch of the tile
Therefore,
The scale of the drawing is 1 inch : 27 inch
Hence, option D is correct

The diagram shows the dimensions of a solid concrete patio in the shape of a right rectangular prism.
How much concrete was used to make the patio?
O A 1.44 m3
OB. 7.80 m
O c. 14.50 m
OD. 30.34 m
Answer: A
Step-by-step explanation: i multiplied all the sides
The quantity of concrete used to make the patio is 1.44 m³
Since the solid concrete patio is a right rectangular prism, to find the amount of concrete used in making the patio, we find its volume.
So, the volume of the patio, V = lbh where l = length of patio = 4.5 m, b = width of patio = 3.2 m and h = thickness of patio = 0.1 m
So, V = 4.5 m × 3.2 m × 0.1 m = 1.44 m³
The quantity of concrete used to make the patio equals the volume of the patio.
So, the quantity of concrete used to make the patio is 1.44 m³
