HELP FAST A vertical slice through a three-dimensional solid produces a two-dimensional shape. (shape is a triangle)
Answers
Answer:
the surface of "C" would be a triangle if sliced vertically
Step-by-step explanation:
If vertical slice through a three-dimensional solid produces a two-dimensional shape is triangular prism, option C is correct.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
If a vertical slice through a three-dimensional solid produces a two-dimensional shape which is a triangle, it means that the solid has a triangular cross-section.
In other words, the cross-section of the solid that is perpendicular to its base is in the shape of a triangle.
A triangular prism is a solid shape that has a triangular cross-section. If you were to take a vertical slice through the prism, the resulting two-dimensional shape would be a triangle.
Hence, if vertical slice through a three-dimensional solid produces a two-dimensional shape is triangular prism

Reasoning The midpoint of AB is on the
y-axis, and AB is parallel to the x-axis. Point A
is located in Quadrant III. Which quadrant
contains point B? Explain.
Answers
Answer:
B is in 4th quadrant.
Step-by-step explanation:
If mid point of AB is on x-axis then and A is in 3rd quadrant then B must be on the opposite side of A.Therefore it is in 4th
B is in fourth quadrant when AB is the midpoint on y axis
What is a quadrant with an example?An area enclosed by the x and y axes is known as a quadrant, and a graph has four of them.To clarify, the x and y axes divide the two-dimensional Cartesian plane into four quadrants.Quadrant I is in the upper right corner, while Quadrants II through IV are arranged from counterclockwise to clockwise.The x-axis (the horizontal number line) and the y-axis connect to divide the coordinate plane into four equal pieces in the cartesian system (the vertical number line).Due to the fact that each of these four areas takes up one-fourth of the entire coordinate plane, they are referred to as quadrants.If the center of AB is on the x-axis
A is in the third quadrant,
let two points ( -2, -2 ) in third quadrant .
then B must be on the side of A that is opposite from A.
B thus comes in fourth.
then points ( 2,-2 ) are in fourth quadrant .

If hexagon ABCDEF is similar to hexagon KLMNOP, which of the following must be true?
Answers
Step-by-step explanation: Similar figures have the same shape, but not necessarily the size. If two figures are similar, then their corresponding angles are congruent so <E ≅ <O because these are the corresponding angles in the similarity statement.
Answer: <E ≅ <O
Step-by-step explanation:
O (3x - 5) + 2x = 90
5x - 5 = 90
5x = 85
x = 17
The angle measures are 34 degrees and 56 degrees.
O (3x - 5) + 2x = 90
5x - 5 = 90
5x = 85
x = 17
The angle measures are 34 degrees and 46 degrees.
O (3x - 5) + 2x = 90
5x - 5 = 90
5x = 95
x = 19
The angle measures are 52 degrees and 38 degrees.
O (3x - 5) + 2x = 90
5x - 5 = 90
5x = 95
x = 19
The angle measures are 19 degrees and 71 degrees.
Answers
Answer:
Equation: [tex]3x-5+2x=90[/tex]
Angle measures: 52 degrees and 38 degrees
Step-by-step explanation:
Hi there!
We're given that the two angles form a right angle, which means they add up to 90 degrees.
Knowing this, we can construct the following equation:
[tex]3x-5+2x=90[/tex]
Now, we must solve for x:
[tex]5x-5=90\\5x=95\\x=19[/tex]
Therefore, x=19. Plug this into the expression for each angle to find their measures:
[tex]3x-5\\= 3(19)-5\\= 57-5\\=52[/tex]
[tex]2x\\=2(19)\\=38[/tex]
Therefore, the two angles measure 52 degrees and 38 degrees.

Answer:
d = 28.6 m
Step-by-step explanation:
Given:
vi = 22.4 m/s
vf = 0 m/s
t = 2.55 s
Find:
d = ??
d = (vi + vf)/2 *t
d = (22.4 m/s + 0 m/s)/2 *2.55 s
d = (11.2 m/s)*2.55 s

What is the percentage change from 305 to 395
Answers
Answer:
29.51%
Step-by-step explanation:
The change from 305 to 395 is the difference between the two numbers. So, it would be 395 - 305 or 90. Now, to find the percentage of change, we need to find what part of the original amount is the change. In other words, we would have to divide 90 by 305. By putting this in a calculator you get about 0.2951. To convert this decimal into a percent, we would multiply by 100 giving us 29.51%.
If using the method of completing the square to solve the quadratic equation x^2+8x+37=0, which number would have to be added to "complete the square"?

Help with the length of the third side?
Answers
Answer:
C. c = 10
Step-by-step explanation:
You have to use the Pythagorean theorem:
c² = 6² + 8²
c² = 36 + 64
c² = 100
c = √100
c = 10
Answer:
c = 10
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2 + 8^2 = c^2
36+64= c^2
100 = c^2
Take the square root of each side
sqrt(100) = sqrt(c^2)
10 -c
