If two prisms have the same volume, do they always, sometimes, or never have the same surface area
Answer:
sometimes
Step-by-step explanation:
Two prisms with the same volume sometimes have the same surface area, but not always, because surface area depends on the dimensions of all prism faces. Different shapes with the same volume, such as a sphere, a cube, and a cylinder, can have significantly different surface areas, especially if their proportions change.
Explanation:If two prisms have the same volume, they do sometimes have the same surface area, but not always. The volume of a prism is determined by the area of the base multiplied by the height, but the surface area includes the areas of all the faces of the prism.
Therefore, two prisms can have the same volume, but if their dimensions—base areas and heights—are different, their surface areas can be very different as well. This holds true for other geometric shapes as well.
Example with Different ShapesFor instance, consider a sphere, a cube, and a cylinder that all have the same volume. According to the formula for a sphere, sphere: volume = 4/3 (pi) (r)³; surface area = 4 (pi) (r)², for a cube, cube: volume = (s)³; surface area = 6 (s)², and for a cylinder, cylinder: volume = height (pi) (r)²; surface area = 2 (pi) (r) (height) + 2 (pi) (r)². Even if all these shapes have a volume set at 1 unit cubed, their surface areas can vary significantly.
Furthermore, changing the shape's proportions while keeping the volume constant (such as elongating a cylinder or a cube) generally increases the surface area.
This is showcased in data where cylinders and cubes shapes elongated in length or width have different surface areas but maintain the same volume.

*What music genre is the 26 to 36 age group’s favorite?
*How many people from the 37 to 47 age group like ‘other’ music?
*Which three genres has the most fans?
Answer:
What music genre is the 26 to 36 age group’s favorite? It's pop
How many people from the 37 to 47 age group like ‘other’ music? 20 people
Which three genres has the most fans? "Pop", "Rock" and "Dance"
Step-by-step explanation:
What music genre is the 26 to 36 age group’s favorite?
The colors indicate the different age ranges. So first you must locate the color belonging to the range of 26 to 36 years, which is gray.
Now, you place that color in the graph and to determine which genre of music is the favorite in that age, you must place the genre with more people aged between 26 and 36. That reads on the “y” axis, which in the graph is seen as "the tallest gray rectangle". Once this is located, you read on the "x" axis the genre to which it belongs. This results in the music genre "pop"
How many people from the 37 to 47 age group like ‘other’ music?
For this case, as in the previous case, you first locate the color belonging to the age range of 37 to 47, which is the color yellow.
But now you must first place that color on the "x" axis, which is the one corresponding to the music genre. In this case you locate the genre "others". Then with the yellow color you read the number of people on the "y" axis.
Note that the numbers marked are every 100, but that between each number there are 5 divisions. This means that the scale is 20 people (obtained as 100 divided by 5)
The color belonging to the age range of 37 to 47 in the genus "others" reaches the first division. This means that the number of people who like this genre is 20.
Which three genres has the most fans?
In this case you should pay attention to which genders ("x" axis) have the greatest number of people ("y" axis), regardless of age. Observing "the longest colored rectangles", which indicate that more people like the genre, and reading the axis of music genres, you can see that the three genres that have more fans are "Pop", "Rock" and "Dance"

the initial vertical velocity of a rocket shot straight up is 42 meters per second. How long does it take for the rocket to return to earth? round your answer to the nearest tenth of a second. show all your work.
The rocket takes approximately 8.6 seconds to return to earth.
Explanation:To calculate the time it takes for the rocket to return to earth, we need to consider the projectile motion in the vertical direction. The initial vertical velocity of the rocket is 42 m/s. We can use the equation for vertical displacement to find the time:
Δy = v0yt + (1/2)gt²
Since the rocket returns to the same altitude, the displacement is 0. Therefore, we have:
0 = (42)t + (1/2)(-9.8)t²
Simplifying this equation and solving for t, we find that it takes approximately 8.6 seconds for the rocket to return to earth.

A Glass paperweight has the shape of a triangular prism. The bases are equilateral triangles with side lengths of 4 inches and a height of 3.5 inches. The height of the prism is 5 inches. find the lateral area and the total surface area of the paperwork.
The lateral area of the triangular prism is 21 square inches and the total surface area is 35 square inches.
Explanation:
To find the lateral area of the triangular prism, we need to calculate the area of all three sides excluding the bases. Since the bases are equilateral triangles with side lengths of 4 inches, the area of each base is ½ × base length × height = ½ × 4 × 3.5 = 7 square inches. The lateral area is the sum of the areas of the three sides, which is 3 × 7 = 21 square inches.
The total surface area of the prism includes the bases as well. So we need to calculate the area of the two triangular bases and add it to the lateral area. The total surface area is 2 (area of base) + lateral area = 2 × 7 + 21 = 35 square inches.

The lateral area of the triangular prism is 60 square inches, and the total surface area is 74 square inches.
To find the lateral area and total surface area of a triangular prism:
Step 1: Calculate the Area of One Triangular Base
The base is an equilateral triangle with sides of 4 inches and a height of 3.5 inches. The area of an equilateral triangle is calculated using the formula:[tex]Area = \frac{1}{2}*base*height[/tex]
So the area is:[tex]Area = \frac{1}{2} *4\ in*3.5\ in = 7\ square\ inches[/tex]
Step 2: Calculate the Perimeter of the Base
The perimeter of the base is:Perimeter = 3 * side length = 3 * 4 in = 12 inches
Step 3: Calculate the Lateral Area
The lateral area of a prism is given by:Lateral Area = Perimeter * height of the prism
Therefore, the lateral area is:Lateral Area = 12 in * 5 in = 60 square inches
Step 4: Calculate the Total Surface Area
The total surface area is the sum of the lateral area and the areas of the two triangular bases:Total Surface Area = Lateral Area + 2 * Area of one baseTotal Surface Area = 60 square inches + 2 * 7 square inches = 74 square inchesThus, the lateral area and total surface area are 60 square inches and 74 square inches.

Two sides of a right triangle measure 7 units and 3 units. What is the area of the square that shares a side with the third side of the triangle?
We can use the Pythagorean theorem to find the length of the third sides.
c²=a²+b²
Where c is the longest (unkwon ) side, a and b are the remaining sides. So,
c²=7²+3²
= 49+9
= 58
So, c=√58
So, the length of the third side or the side length of square is √58.
So, the area of the shaded region (square)= c²
=(√58)²
=58
So, the area of the square is 58 units².
Answer: 58 units squared
