Answer:

11

Step-by-step explanation:

Whole numbers are all those numbers that are zero or greater then zero, so:

{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, ......}

The list of the pairs is the following:

(0, 10)

(1, 9)

(2, 8)

(3, 7)

(4, 6)

(5, 5)

(6, 4)

(7, 3)

(8, 2)

(9, 1)

(10, 0)

Two pairs with the same numbers, but in different position are not the same thing. They are two different pairs.

For example, (2, 8) and (8, 2) are different. You can imagine them as points on a Cartesian coordinate system to understand why they are different. They are two different points.

What is the surface area of the right prism given below?
posledela

Answer: Option D.

Step-by-step explanation:

You can calculate the surface area of this right prism by adding the area of its faces.

You can observe that the faces of the right prism are:  Three different rectangles and two equal triangles.

The formula for calculate the  area of a rectangle is:

A=lw

 Where "l" is the lenght and "w" is the width.

The formula for calculate the  area of a triangle is:

A=\frac{bh}{2}

Where "b" is the base and "h" is the height.

You can observe that the hypotenuse of the each triangle is the width of one of the larger rectangle, then , you can find its value with the Pythagorean Theorem:

a=\sqrt{b^2+c^2}

Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.

Then, this is:

a=\sqrt{(8units)^2+(15units)^2}=17units

Therefore, you can add the areas of the faces to find the surface area of the right prism (Since the triangles are equal, you can multiply the area of one of them by 2). This is:

SA=(10units)(8units)+(15units)(10units)+(17units)(10units)+2(\frac{(15units)(8units)}{2})\\\\SA=520units^2
