The volume of the prism is determined as  1,416 m³ and the surface area of the prism is 664.8 m².

The volume of the prism is determined from the product of base area and slant height of the prism.

Base of the prism, A = ¹/₂bh = ¹/₂ x 12 x 20 = 120 m²

Volume = AL

where;

L² = (12/2)² + (20.3/2)²

L² = 6² + 10.15²

L² = 139.0225

L = 11.8 m

V = AL

V = 120 x 11.8 = 1,416 m³

A = bh + pL

A = (12 x 20) + 11.8(12 + 12 + 12)

A = 664.8 m²

The system of equation x − y = 2 and −2x+2y = −4 is dependent becasue the they have same coefficient of x and y option second is correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

As we know, if the two linear equations have the same coefficient of x and y they are dependent or if the graph of two linear equations is the same then the equations are dependent.

From the given options, we can see the system of equations:

x − y = 2 and −2x + 2y = −4 are the same equation.

Take the equation −2x + 2y = −4 and divide by -2 on both sides, we get:

x - y = 2

This is the same equation as x − y = 2

Thus, the system of equation x − y = 2 and −2x+2y = −4 is dependent becasue the they have same coefficient of x and y option second is correct.

Answer:

1197/2

598 R 1

598½

Step-by-step explanation:

use division method

Answer:

2 divided by 1197 equals 598 with a remainder of 1.

Step-by-step explanation:

There is also another way to do divison if it is confusing for others.

If you multiply 598 and 2 that equals 1196. That is the closest number that can go into 2 598 times. So what i am trying to say is that since the problem is 2 divided by 1197 you have to figure out what number you need to multiply that can go into two. So 2 divided by what equals 1197 OR 2 divided by what number can equal 1197 or any number that is close to 1197. So 598 times 2 equals 1196. With a remainder of 1

I hope this helps because this strategy worked for me when i first learned division so i hope this helps as well :)

Answer:

The area is 27m.

Step-by-step explanation:

We can first seperate this shape into two shapes. I seperated the 3x6 rectangle and the 3x3 square. Now we can find the area of these individual shapes. 3x3=9 and 3x6=18. We can now add these two numbers together to get the area of this shape. 9+18=27m. Therefore, the area of this shape is 27m.

Answer:

In order for the shapes to be in the same category, we need the following: 2 triangles and 1 quadrilateral with 2 sets of parallel lines.  

Step-by-step explanation:

Remember Generalization is like an inference.

You need to write a statement that is based on the given information about Anna's shapes.

_______________________________________________________

If we look at Anna's shapes we have 2 quadrilaterals and 1 triangle.

Then, the "following" shapes have the same properties meaning 2 quads and 1 triangle.

We can go straightforwardly by saying the shapes that Anna chose are 2 quadrilaterals and 1 triangle.

Parallel sides are only shown on 2 of the shapes (the square and the parallelogram).

There are 3 triangles: 1 right, 1 obtuse, and 1 equilateral or acute.

______________________________________________________
Here's my generalization:

If we look at the shapes that Anna chose, we can identify 2 quadrilaterals and 1 triangle. The following shapes don't belong with the ones she chose because there are 2 triangles (equilateral and one right triangle). Then, we have a square with 2 sets of parallel lines which the parallelogram has. The other quadrilateral doesn't have any parallel lines which can't be a trapezoid either. In order for the shapes to be in the same category, we need the following: 2 triangles and 1 quadrilateral with 2 sets of parallel lines.

area of S = 10×10 = 100

The sum of the exterior angles of a decagon is 360 degree if each exterior angle measure is 36 degree.

A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.

We have:

Decagon, in which the number of sides is 10

The formula for the sum of the interior angles in n number of polygon:

Sum = 180(n - 2)

Plug n = 10

Sum = 180(10-2)

Sum = 1440

Each interior angle = 1440/10 = 144 degree

Each exterior angle = 180 – 144 = 36 degree

The sum of the exterior angles = 36×10 = 360 degree

Similarly, we can find any angle measure for interior or exterior by using the formula:

Sum = 180(n—2)

Where n is the number of sides.

Thus, the sum of the exterior angles of a decagon is 360 degree if each exterior angle measure is 36 degree.

3. 540 cm^3

4. 1476 cm^3

Step-by-step explanation:

1. rectangular prism volume equation is: V = lwh, where l = length, w = width, h = height. Substitute known values into this equation: V = 5 x 8 x 15 and we get V = 600 cubic cm.

2. V = (1/2)bhl, where the base and height are dimensions of the triangle. V = (1/2)6 x 2 x 4 and we get V = 24 cubic cm

3. V = Bh, where B is the base area and h is the perpendicular height. V = 45(12). So, V = 540 cm^3

4. Same thing with this one: V = Bh. Substitute known values into this equation: V = 82(18), which means V = 1476 cm^3
