Which expression best defines a rational number?

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

Answers

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.

⚠️(Long Math Question!)⚠️ PLEASE HELP! THIS IS A TEST! "Jack compared the number of pink rose buses to the number of yellow rose bushes as part of a school project. Jack counted 3 pink rose bushes to every 8 yellow rose bushes. Later in the year, there was a drought and many rose bushes died. New rose bushes were planted to make sure there were the same number of rose bushes before the drought. The new ratio of the number of pink rose bushes to the number of yellow rose bushes is 5:6. After planting new yellow rose bushes there were 180 yellow rose bushes. How many pink and yellow rose bushes were there before the drought? Explain your answer using a tape diagram."

Answers

67.5 pink 180 yellow

The ratio at the beginning of the year was 3:8 then it became 5:6 it says that they planted the rose bushes so there would be the same number as before so that means the ratio was 3:8 with 180 yellow rose bushes, to start solving you have to find out how many yellow rose bushes were represented by a 1 in the ratio, to get that divide 180 by 8 to get 22.5, now you know that a 1 in the ratio is equal to 22.5 bushes, multiply 22.5 by 8 to get the total number of yellow bushes and multiply it by 3 to get the total number of pink bushes so then you get (obviously) 180 total yellow rose bushes and 67.5 total pink rose bushes before the drought, you can check that by simplifying the ratio of 67.5:180 which simplifies into 3:8 which means the numbers check out!

In which scenario does Seth start closer to school?


In which scenario does Seth travel at a greater speed, and what was the rate?

Answers

Answer:

In which scenario does Seth start closer to school?  

bus stop, 5 miles from home

In which scenario does Seth travel at a greater speed, and what was the rate?  

friend’s house, 2 miles every 3 minutes

The speed of Seth when he travels from the Bus stop will be faster. Because the speed is greater.

What is an average speed?

The distance covered by the particle or the body in an hour is called the average speed. It is a scalar quantity. It is the ratio of the total distance to the total time.

We know that the average speed formula is given as,

Average speed = Total distance / Total time

The speed of Seth when he travels from the Bus stop will be

Average speed = (8 - 5) / (6 - 0)

Average speed = 3 / 6

Average speed = 0.5 miles per hour

The speed at Seth when he travels from the Friend's house will be

Average speed = (8 - 4) / (9 - 3)

Average speed = 4 / 6

Average speed = 0.33 miles per hour

The speed of Seth when he travels from the Bus stop will be faster. Because the speed is greater.

Answer: Lower left corner  [tex]\frac{29}{18+29} \times 100[/tex]

We have 29 people who chose fishing out of 18+29 people who filled out the survey. We don't use 60 because not everyone filled out the survey, and we're only focusing on survey participants. The "times 100" at the end will move the decimal point 2 spots to the right, and convert it to percent form.

For example, if you had 2 people who liked fishing out of 8 total then 2/8 = 0.25 = 25% of the people like fishing.

Answer:it's C) 29×100/18+29

Step-by-step explanation:

For the percentage, we need the total number of boys who completed the survey which is 18+29. Again, the number of boys who chose fishing is 29. So, we should divide 29 by (18+29) & multiply 100c with it in order to get the percentage .

Step-by-step explanation:

We know (by definition) that: 1⁢oz = 0.0625⁢lb

We can set up a proportion to solve for the number of pounds.

1⁢oz124⁢oz =   0.0625⁢lbx⁢lb

Now, we cross multiply to solve for our unknown x:
