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 1
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.

7a+b-9c+17d

Step-by-step explanation:

-5 ( a-2b+3c -4d) - (-3) (4a -3b+2c-d)

Distribute

-5a+10b-15c+20d+12a-9b+6c-3d

Combine like terms

7a+b-9c+17d

7a + b - 9c + 17d

step-by-step explanation

(- 5)( a - 2b +3c - 4d ) - (-3)( 4a - 3b+2c - d )

- 5( a - 2b + 3c - 4d ) - (-3)( 4a - 3b + 2c - d)

Using Distributive property

- 5a + 10b - 15c + 20d + 12 a - 9b + 6c - 3d

Arranging like terms together

- 5a + 12a + 10b - 9b -15c + 6c + 20d -3d

7a + b - 9c + 17d

A circle has a diameter of 36 cm. Which expression could represent the area of this circle in square cm?

Answers

Answer:

Step-by-step explanation:

You haven't given the choices but I believe the equation below could represent the area of the circle:

(pi ~ 3.14) * (18)^2

The area for a circle is pi * radius squared, so to find the radius divide the diameter by 2.

3.14(18^2) basically do that

Answer:

B

Step-by-step explanation:

y = -2x

The negative slope means it goes down from left to right ( we eliminate Choice a)

Y = mx+b  b is the y intercept

The b in the above equation is 0, so it must go through zero

That means the graph of the line is B

Answer:

B

Step-by-step explanation:

Because the equation is put in y = kx form the y intercept will be at the origin (0,0)

All graphs except B do not go through the origin

So b likely graphs y = -2x

Answers

Hi, sorry for a late response, but here are the answers if they are still helpful?

The volume would be about 4,188.79

(if rounded and if not the answer is below and so is the work.)

Volume = 4

—— πr3

3

= 4

—— ✖️ π ✖️ 103

3

= 4188.7902047864 centimeters^3

The surface area would be about 1,256.64

(if rounded and if not the answer is below and so is the work.)

Surface Area = 4πr2

= 4 × π × 102

= 400π

= 1256.6370614359 centimeters^2

I believe it’s 4,188.79. I’m not sure

The theoretical probability of selecting a consonant at random from a list of letters in the alphabet is 21/26. Wayne opens a book, randomly selects a letter on the page and records the letter. He repeats the experiment 200 times. He finds p(consonant) = 60%. How does the theoretical probability differ from the experimental probability? What are some possible sources for this discrepancy. I will mark brainlest

Answers

Answer:

The theoretical probability in this case is calculated by taking the number of consonants in the alphabet and dividing it by total number of letters in the alphabet and the distribution of letters in the written language is different than the distribution of letters in the alphabet.

connor found out that 60% of 40 is the same as 25% of the number n. what is the value of n?

Answers

Answer:

96

Step-by-step explanation:

Step 1: Multiply 60% by 40

40 x .60 = 24

24 is 60 percent of 40

Step 2: If 24 was 25% of n, then we have to divide 100 by 25 to see how much we have to multiply 24 by.

100 ÷ 25 = 4

Step 3: Multiply 4 by 24

4 x 24 = 96

The answer is 96 :)
