First, I'd like to say that this question is flawed because the diameter of the spool changes as you pull the line out. Some would argue it's negligible I suppose.

At any rate, assuming there's a magic spool where the diameter doesn't change, let's find the cicumference so we can find the length of one wrap around the spool.

circumference = 2*pi*r = 2 * pi * 4cm = about 25.133 cm

Now if it turns 16 times we'll have 16 times the circumference.

16 * (25.133 cm)

= 402.128 cm

kotegsom [21]
The answer to your question is A. rational numbers.

Rational numbers are closed under any set of operations.

Integers are not closed under division because 1/2 is not an integer.

The set {-1, 0, 1} is also not closed under division because -1/5 does not fall in that set.

Whole numbers are not closed under division because 5/3 will produce a number that is not a whole integer.

Your answer is A. rational numbers.

A discount book store sells hardcover books for $8 each and paperbacks for $4 each.The number of hardcover books, h, sold one da
vaieri [72.5K]

Jean-Paul's error is that he should have written the second equation as h = 4 p + 2.

<h3 />

<h3>How to solve an equation?</h3>

The hardcover book is $8 each and paperbacks for $4 each.

The number of hardcover books, h, sold one day was 2 more than four times the number of paperback books, p, sold that same day.

Therefore,

h = 4p + 2

Hence,

8h + 4p = 160

Therefore, the right equation are as follows:

h = 4p + 2

8h + 4p = 160

Hence, Jean-Paul should have written the second equation as h = 4 p + 2.

Maureen walked 3 miles how many feet did she walk
Ostrovityanka [42]

Answer:

15,840 feet.

Step-by-step explanation:

We have been given that Maureen walked 3 miles. We are asked to convert the distance walked by Maureen in feet.

Since we know that 1 mile equals 5,280 feet, so to convert our given distance we will multiply 3 by 5,280.

\text{Number of feet Maureen walked}=\text{3 miles}\times \frac{5,280\text{ feet}}{\text{Mile}}

\text{Number of feet Maureen walked}=3\times 5,280\text{ feet}

\text{Number of feet Maureen walked}=15,840\text{ feet}

Therefore, Maureen walked 15,840 feet.

What is the mean of the data set? {32, 33, 34, 34, 36, 38, 38, 38, 40, 42}
Sphinxa [80]
Add all the numbers:

32 + 33  34 + 34 + 36 + 38 + 38 + 38 + 40 + 42 = 365

There are 10 numbers.

Divide:
Total by how many numbers there are

Total = 365
Numbers = 10

365 / 10 = 36.5

The mean is 36.5

Hope this helped☺☺
