Answer:
The perimeter of the given composite figure is:
106 ydStep-by-step explanation:
The perimeter is defined as the sum of the sides in a figure, therefore, what you should do in this exercise is to add all the yards of the sides of the compound figure, however, you should notice that there are two sides of which They do not give you the measurement and you must identify it based on the sides that do have it, which would be:
Vertical line measurement = (19 + 4-17) yards Vertical line measurement = 6 yardsIn the previous case, the two measures on the other side that are complete are used, which are 19 yards and 4 yards respectively, then the measurement that is on our same side (17 yards) is subtracted and thus we obtain the value of the vertical line that it did not have, now that of the horizontal line:
Horizontal line measurement = (30-12-15) yards Horizontal line measurement = 3 yardsIn this case, something similar was done, the total measurement of the base was taken and the measurements of the upper zone were subtracted, with which the measurement of the remaining zone was found.
All the measures are added together:
The perimeter of the figure = 30 yd + 17 yd + 12 yd + 6 yd + 15 yd + 4 yd + 3 yd + 19 yd = 106 ydAnswer:

Upon calculating the volume of the given cylinder and comparing it with each option, it is determined that none of the provided cylinders have the same volume as the cylinder with a height of 32 meters and a diameter of 20 meters.
Explanation:The question is asking which cylinders have the same volume as a cylinder with a height of 32 meters and a diameter of 20 meters. To find this out, we first calculate the volume of the given cylinder. The formula for the volume of a cylinder is[tex]V = \(\pi r^2h\)[/tex], where V is the volume, [tex]\(r\) i[/tex]s the radius of the base, and h is the height of the cylinder. In this case, the radius (half of the diameter) is 10 meters, so the volume is:
[tex]V = \(\pi (10)^2 \times 32\) = 320\(\pi\) cubic meters.[/tex]
Now, let's check each option:
A cylinder with height of 16 meters and diameter of 40 meters has a volume of 16[tex]\(\pi (20)^2\) = 6400\(\pi\)[/tex] cubic meters, which is not equal.A cylinder with height of 64 centimeters and diameter of 5 meters is not comparable without conversion and does not match.A cylinder with height of 8 meters and diameter of 40 meters has a volume of[tex]8\(\pi (20)^2\) = 3200\(\pi\)[/tex]cubic meters, which is not equal.A cylinder with height of 64 centimeters and diameter of 10 meters is not comparable without conversion and does not match.A cylinder with height of 20 meters and diameter of 32 meters has a volume of [tex]20\(\pi (16)^2\) = 5120\(\pi\)[/tex]cubic meters, which is not equal.A cylinder with height of 128 meters and diameter of 10 meters has a volume of [tex]128\(\pi (5)^2\) = 3200\(\pi\)[/tex] cubic meters, which is not equal.Therefore, none of the provided options have the same volume as the given cylinder.
The cylinders with heights and diameters of 16 meters and 40 meters, and 128 meters and 10 meters, respectively, have the same volume as the given cylinder.
To find cylinders with the same volume as the given cylinder (height = 32m, diameter = 20m), we calculate its volume and compare it with the volumes of the listed cylinders. Cylinders with heights and diameters of 16 meters and 40 meters, and 128 meters and 10 meters, have the same volume as the given cylinder.
The question involves finding which cylinders have the same volume as a cylinder with a height of 32 meters and a diameter of 20 meters. To solve this, we first calculate the volume of the given cylinder using the formula for the volume of a cylinder, V = πr²h, where r is the radius (half of the diameter) and h is the height.
The volume of the given cylinder is V = π(10²)(32) = 320π cubic meters. We then apply the same formula to each of the listed cylinders, converting dimensions to the same units where necessary, to identify which ones have the same volume.
A cylinder with height of 16 meters and diameter of 40 meters has a volume of 320π cubic meters, which matches.A cylinder with height of 8 meters and diameter of 40 meters does not match because its volume is 160π cubic meters.A cylinder with height of 128 meters and diameter of 10 meters also has a volume of 320π cubic meters, which matches.Therefore, the cylinders with heights and diameters of 16 meters and 40 meters, and 128 meters and 10 meters, respectively, have the same volume as the given cylinder.

What is the solution of the system of equations 2x - 5y = 11 and -2x + 3y = -9?
Answers
Answer:
x= 3, y= -1
Step-by-step explanation:
Let's solve your system by substitution.
2x−5y=11 and −2x+3y=−9
Solve x in 2x-5y=11
2x-5y=11 (add 5y to both sides)
2x = 5y + 11 (divide 2 by both sides)
x=5/2y + 11/2
substitute 5/2y+11/2 for x in -2x+3y=-9
-2x+3y=9
-2 (5/2y+11/2)+3y=-9
-2y-11=-9 (simplify both sides)
-2y-11=-9 (add 11 to both sides)
-2y=2 (divide both sides by -2)
y=-1
substitute your y (-1) in x = 5/2y + 11/2
x = 5/2y + 11/2
x=5/2(-1)+11/2
x=3
therefore, y= -1 and x = 3
The ratio of side lengths for two similar cubes is į.
Determine the ratios for each of the following. Show your work or explain how you got your answers.
a. the perimeter of one face of the smaller cube compared to the perimeter of one face of the larger
cube
b. the total surface area of the smaller cube compared to the total surface area of the larger cube
c. the volume of the smaller cube compared to the volume of the larger cube
Answers
The ratio of the perimeter of one face for the two cubes is 1/2, the ratio for the total surface area is 1/4, and the ratio for the volume is 1/8.
Explanation:The student wants to find the ratios of the perimeter of one face, the total surface area, and the volume of two similar cubes having side length ratio of 1/2.
Perimeter of one face: Since each face of a cube is a square, the perimeter is 4 times the side length. As the ratio of side lengths is 1/2, the ratio of the perimeters would also be 1/2. This is because perimeter is a one-dimensional measure, therefore the ratio stays proportional to the side length.Total Surface Area: The total surface area of a cube is 6 times the area of one face (a square). Since the area is a two-dimensional measure, it's proportional to the square of the side length ratio, hence the ratio of the surface areas of two similar cubes would be (1/2)² = 1/4.Volume: The volume of a cube is the cube of the side length. Since the volume is a three-dimensional measure, it is proportional to the cube of the side length ratio, so the ratio of the volumes of two similar cubes would be (1/2)³ = 1/8.Learn more about Ratio of Similar Cubes here:

A bee flaps its wings about 82,800 times an hour, and a hummingbird flaps its wings about 28,800 times an hour.
About how many times faster does a bee flap its wings than a hummingbird?
Estimate using a single digit times a power of 10.
Answers
Answer: About 2.875 times more than a hummingbird
Step-by-step explanation: The way you can solve this problem is just by dividing 82,800 by 28,800. If you want to check your work multiply 28,800 and 2.875.
A bee flaps its wings approximately 3 times faster than a hummingbird.
Explanation:Bee: 82,800 times/hour ≈ 8.3 × 10^4 times/hour
Hummingbird: 28,800 times/hour ≈ 2.9 × 10^4 times/hour
Now, let's compare the two estimates:
8.3 × 10^4 (bee) is approximately 3 times faster than 2.9 × 10^4 (hummingbird).
So, a bee flaps its wings about 3 times faster than a hummingbird.

3x + 4y = -23
x = 3y + 1
y =
X=
Answers
Answer:
(-5, -2)
Step-by-step explanation:
3x+4y=-23
x=3y+1
since we have what x is, we need to subsitute
3( 3y+1) + 4y= -23
no we need to multiply the number inside the parenthesis by 3
9y + 3 + 4y= -23
combine like terms ( add the numbers or variables that look alike)
9y+4y is 13y
13y+3= -23
since we need to get the y alone we need to subtract 3 on both sides since its the opposite of adding
13y+3-3=-23-3
13y= -26
now we divide 13 on both sides to get Y alone
13y/13= -26/13
y= -2
now since we have y we need to substitute it to find x
x= 3y+1
x= 3( -2) +1
now we mutliply 3 with -2
x= -6 +1

4.Is it sometimes, always, or never true that, if A and B both have dimensions n x n , AB=BA ? Explain.
Answers
Answer: Is true sometimes.
Step-by-step explanation:
I guess that here we have two matrices, A and B, that are nxn.
We can see that if those matrices can conmutate, then we can try it with some simple matrices.
[tex]A = \left[\begin{array}{ccc}1&0\\0&-1\end{array}\right] . B = \left[\begin{array}{ccc}2&0\\1&1\end{array}\right][/tex]
Here, we would have that:
[tex]AB = \left[\begin{array}{ccc}2&0\\-1&-1\end{array}\right][/tex]
[tex]BA = \left[\begin{array}{ccc}2&0\\1&-1\end{array}\right][/tex]
You can see that AB and BA are different, then the statement is not always true.
But it is true sometimes, if A or B are the identiti, then I*A = A*I, in this case would be true.
It is also true if A and B are diagonal matrices, let's prove it:
[tex]A = \left[\begin{array}{ccc}a&0\\0&b\end{array}\right] , B = \left[\begin{array}{ccc}c&0\\0&d\end{array}\right][/tex]
[tex]AB = \left[\begin{array}{ccc}ac&0\\0&bd\end{array}\right] = BA[/tex]
