how would you change the sentence into a true statement? some irrational numbers are also rational numbers..... A. All irrationa
Fynjy0 [20]

Irrational numbers cannot be classified as rational numbers. - EXPLANATION - both are different completely, according to as I think, and thus they cannot be inter-related. Irrational like - root2, root3, and all those that cannot be further solved completely. Their decimal representation is neither recurring nor ending e.g. 1.101001000100001000001.... and so on while rational number are consisting of whole numbers, integers, natural numbers, and all the constants and their decimal representation can be non ending but recurring.

5. d. Irrational numbers cannot be classified as rational numbers. - EXPLANATION - out of the options this one's correct. As I above said, all numbers as far as I know can be categorized into unreal and real numbers out of which real numbers consist of irrational and rational numbers while unreal numbers, I don't know as I have not been taught about them yet and neither do you have been, as I think so. All I know is that, as far as I have been taught, unreal number are not connected to real numbers.

6. Every real number is a rational number. - EXPLANATION - As I told you above, real numbers can also be irrational so this is false.

Hope this helps!

STatiana [176]
I believe it might’ve made 2,400 books, because if you divide 70 from 1680 you get 24, meaning it’s pressing about 24 books per hour, if it’s printing twice that you would multiply 48 by 50 and get 2,400.

What is the perimeter and area of the photo below? And please show me how you did it. I need it for a school math group, and I’m
adoni [48]

Answer:

Assuming the area is made up of a square and a semicircle.

<u>Perimeter</u>

The side length of the square = 18 ft

We can see 3 full side lengths plus one side length from which we need to subtract 12 ft (see attached diagram).

⇒ perimeter of the square = (3 x 18) + (18 - 12)

                                                          = 54 + 6

                                                          = 60 ft

Circumference of a circle = \pid (where d is the diameter)

⇒ arc length of the semicircle = 1/2 circumference

                                                  = 1/2 · \pi · 12

                                                  = 6\pi ft

Total perimeter = 60 + 6\pi = 78.8 ft (nearest tenth)

<u>Area</u>

Area of a square = s² (where s is the side length)

⇒ area of square = 18²

                             = 324 ft²

Diameter = 2r  ⇒  r = 1/2 diameter

Area of a circle = \pir²  (where r is the radius)

⇒ area of the semicircle = 1/2 · \pi · 6²

                                         = 18\pi ft²

Total area = 324 + 18\pi = 380.5 ft² (nearest tenth)
