Which expression best defines a rational number?

A. has a decimal form that can be rounded
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.

Step-by-step explanation:

The % itself stands for a ratio of 100, so 70% would be 70/100

Answer:

70/100

Step-by-step explanation:

This is because if you break down a percantage, it is just a fraction or decimal. The numerator is 70 because 70/100 = 0.7

0.7 is just the decimal form of the percent "70%"

There are 5,280 feet in 1 mile. If Riley ran 26,400 feet, how many miles did she run? [Type your answer as a number.]

________ miles

Answers

Answer:

Step-by-step explanation:

5,280=1mile

26,400=26,400/5,280

5miles.

Answer:
Riley ran 5 miles

Step-by-Step:
If in 1 mile there is 5,280 feet and Riley ran 26,400ft we can divide 5,280 and 26,400 to find how many miles she ran. 5,280 / 26,400 = 5. Riley ran 5 miles

The rate to rent a truck for a day is a one-time fee of $35 and $0.20 per mile.

Write an expression to model this situation.
How far could you travel if you drove 40 miles?

Answers

Answer: y= $0.20x + $35 or y= $0.20 * 40 + $35 (Depending on what you mean)

Step-by-step explanation:

The equation for these types of problems is y = mx + b.

M would be $0.20, because that is the value that can repeat, based on x. For example, if this was 2 dollars per mile (m) for 3 miles, (x) than y, the total amount for mx would amount to 6 dollars.

Now, 35$ Is a one time fee (b), so you can add that separately to $0.20x.

If you plug everything in, you would get y= $0.20x + $35.

I am not very sure about what you mean by “ How far you could you travel if you drove 40 miles”, but if you mean how much would you pay to drive 40 miles, I can help there.

Now that we know x would be the amount of miles, we can plug that into the equation.

You would get y= $0.20 * 40 + $35.

Sorry, I’m not that good at explaining, but I hoped this helped!

y= .20x + 35

It would cost $43 to travel 40 miles

Answer:

  a) T(t) = -13 +0.5t

  b) D(t) = -4 -0.25t

  c) 12 seconds

  d) 7 feet

Step-by-step explanation:

a) The turtle starts at -13 feet and increases its elevation relative to the water's surface by 0.5 ft/second. After t seconds, the turtle will be 0.5t feet closer to the surface, so its depth will be ...

 T(t) = -13 +0.5t

__

b) The diver starts at -4 feet and decreases their elevation relative to the water's surface by 0.35 ft/second. After t seconds, the diver will be 0.25t lower than the initial position, so their depth will be ...

  D(t) = -4 -0.25t

__

c) The diver and turtle will be at the same depth when ...

  T(t) = D(t)

  -13 +0.50t = -4 -0.25t

  0.75t = 9 . . . . . . . . . . . . add 13+0.25t

  t = 12 . . . . . . . . . . . . . . . divide by 0.75

The diver and turtle will be at the same depth after 12 seconds.

__

d) That depth will be ...

  T(12) = -13 +0.5(12) = -13 +6 = -7

The diver and turtle meet at a depth of 7 feet.

Answers

Answer:

x=9

Step-by-step explanation:

x + x - 4 + x - 4 = 19

3x - 8 = 19

3x = 19 + 8

3x = 27

x = 9

Answer: x=9

Step-by-step explanation:

There are three sides 2 that are x-4 and 1 that is x. The equation would be

x+2(x-4)= 19 so you would simplify to get

X+2x-8=19 then 3x=27 then divide by three to get x=9
