B. has a decimal form that cannot be rounded
C. has a decimal form that is terminating or repeating
D. has a decimal form that is nonterminating and nonrepeating

A for sure because it can be

Rational numbers are terminating or repeating numbers. Therefore, option C is the correct answer.

We need to check from the options which expression best defines a rational number.

What are rational numbers?

Rational numbers: Rational numbers are in the form of p/q, where p and q can be any integer and q ≠ 0. This means that rational numbers include natural numbers, whole numbers, integers, fractions of integers, and decimals (terminating decimals and recurring decimals).

Rational numbers can be easily identified with the help of the following characteristics.

All integers, whole numbers, natural numbers, and fractions with integers are rational numbers.If the decimal form of the number is terminating or recurring as in the case of 5.6 or 2.141414, we know that they are rational numbers.In case, the decimals seem to be never-ending or non-recurring, then these are called irrational numbers.

So, from the definition, we understood that rational numbers are terminating or repeating numbers.

Therefore, option C is the correct answer.

whats the surface area?

Answers

Answer:

1108 in²

Step-by-step explanation:

You want the total surface area of the pentagonal prism shown.

Base area

The area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...

A = LW +1/2bh

A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches

Lateral area

The lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.

LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches

Total area

The total surface area of the figure is the sum of the two base areas and the lateral area:

SA = 2(114 in²) +880 in² = 1108 in²

The surface area of the composite figure is 1108 in².

Bella is baking 34 cookies for the holiday party tonight. She baked 18 before leaving for school and will bake the rest when she returns home.
Which equation shows how many cookies Bella will bake when she returns home?

a: 18 = x − 34
b: 34 = 18x
c: 34 = x − 18
d: 34 = x + 18

Answers

Answer: d: 34= x + 18

Step-by-step explanation: 34 is the total, and she already made 18. So this means that it would be 34-18=x. OR 18+x=34 which can also be written as 34=18+x

D.12.66
pls help me

Answers

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Which sign makes the statement true?
5.7 x $10^{2}$ 5,700,000,000,000

Please help me quickly!!

Answers

Answer:

Step-by-step explanation:

the exponent will tell you how many places u need to move the decimal. 5.7 × 10 to the 2nd power = 570. u moved the decimal 2 places to the right.

The sign that makes the statement true is "=".

If we interpret the statement correctly "5.7 x 5,700,000,000,000" means to multiply 5.7 with 5,700,000,000,000, which gives us the result of 32,490,000,000,000.

Therefore, we can write the statement as: 5.7 x 5,700,000,000,000 = 32,490,000,000,000.

1/6; 5/6

Brainlist for positive attitude and correct answer :D

Answers

Answer: The correct answer is:

Probability of rolling a number less than 3: 2/6 or 1/3

Step-by-step explanation:

Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.

Probability of not rolling a number less than 3: 4/6 or 2/3.

Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

Answer:

Step-by-step explanation:

For the first equation,

h-3=9, we need to put all the knowns (numbers) on one side and all the variables on the other side. because equations are like a scale, if we do the same thing to both sides of the equation, the equation will still be true. for this equation, if we add 3 to both sides, we will get:

h-3+3=9+3

this can be simplified to:

h=12

this is your answer.

For the second equation,

we can apply the same principle for the first equation to the second equation.

1/2 x h = 10

can also be written as:

1/2 of h = 10

we can multiply both sides by 2 to get:

1h=20

h=20
