Which describes all decimals that are rational numbers?
A. the decimal terminates or repeats.
B. the decimal terminates and does not repeat.
C. the decimal neither terminates nor repeats.
D. the decimal repeats and does not terminate.

Answers

Answer: A. the decimal terminates or repeats.

===========================================================

Explanation:

A terminating decimal example would be something like 0.2 which converts to the rational number, aka fraction, 1/5. The word "terminate" means "stop", so it's any decimal that doesn't go on forever.

A repeating decimal is something like 0.33333 where the 3s go on forever, and that converts to 1/3.

If any of these conditions happen, then the number is rational.

--------

For something like pi = 3.14159... where there isn't a pattern and it goes on forever, then we consider this number irrational. The term "irrational" literally means "not rational". So this allows us to rule out choice C.

Choices B and D are partially true, but they only paint half the picture needed to form all rational numbers. Choice A is the most complete statement.

In other words, while choice B is technically true, it leaves out repeating decimals. Choice D is the same way but it leaves out terminating decimals. So we can rule out choices B and D.

The answer is aaaaaaaaaaaaaaaaaaaa

Answers

Answer:

Step-by-step explanation:

I conclude that you need to find the value of x

6(5 - 3x) - 5(3x + 2)

30 - 18x -15x -10 = 0

-33x +20 = 0

33x = -20

x = -20/33

The answer is

find surface area of the prism pls!!!!! explain too. I really need help!!!

Answers

i believe you have to multiply meaning 6x5x2 it’s 60.

Answer: 104 square inches

Step-by-step explanation:

The surface area of a prism is the sum of the surface are of all of it's faces.

We can turn that into this equation SA = 2(w x l) + 2(l x h) + 2(w x h) where w is width, l is length, h is height, and 2(w x l) is the top and the bottom surface areas, 2(l x h) is the left and right sides, and 2(w x h) is the front and back.

Substitute to get this: SA = 2(6 x 2) + 2(2 x 5) + 2(6 x 5)

Simplify with multiplication to get this: SA = 24 + 20 + 60

Simplify with addition to get this: SA = 104

Add the unit label and you get 104 square inches.

There are many cones with a height of 12 inches. Let r represent the radius and V
represent the volume of these cones.

Plot points that show the volume when r=1, r=2, r=3, and .r=4.

HELP!

Answers

Answer:

If R = 1, ~12.57 is the y. (r is the x.)

If R = 2, ~50.27

If r = 3, ~113.1

If r = 4, ~201.06

Step-by-step explanation:

The formula of a cone is pi * r^2 * h/3

If r = 1, we have pi * 1^2 * 12/3

12/3 = 4

and 1^2 = 1

pi * 1 * 4

4 * pi = ~12.57

if r = 2, we have an imrpoved formula,

pi*2^2 * 4 (h/3 became 4 since 12/3 = 4)

2^2 = 4

4*4 = 16

pi * 16 = ~50.27

If r = 3

our formula is pi*3^2*4

3^2 = 9

pi*9*4

9*4 = 36

36* pi = ~113.1

If r = 4,

our formula is

pi*4^2*4

4^2 = 16 and 16*4 = 64

pi*64 = ~201.06.

Answer:

If R = 1, ~12.57 is the y. (r is the x.)

If R = 2, ~50.27

If r = 3, ~113.1

If r = 4, ~201.06
