A bicycle wheel makes five rotations. The bicycle travels 41.87 ft. Find the diameter of the wheel in inches. Use 3.14 for pi. The diameter of the wheel is about nothing in.

Answers

Answer:

The diameter is 32.04 Inches

Step-by-step explanation:

If the Bicycle makes 5 rotations and it equals 41.87 ft

Then 1 rotation around the circumference is

41.87/5 = 8.374 ft

Circumference = \pi d

8.374 = 3.14*d

Divide both sides by 3.14

d = 8.374/3.14

d = 2.67 ft

To convert feet to inches, we multiply by 12

d = 2.67*12 inches

d = 32.04 Inches

A potter use 3/5 of a pound of clay to make a bowl.How many bowls the potter make from 10 pounds.

Answers

We are writing proportion:
(3)/(5) of a pound of clay -1 bowl
10 pound of clay - x bowl
We are looking for x which is amount of bowl
After cross multiplication:
(3)/(5)x=10
x=(50)/(3)=16,66 ,so from 10 pounds we will make 16 bowls.
10 divided by 3/5 = 10 x 5/3 = 50/3 = 16 and 2/3 bowls.

That's the mathematical answer.  In the real-world pottery shop, he can
make 16 complete bowls, and have 2/5 pound of clay left over.

Suppose you want to factor the expression x2 + 2xn+n?. Given that n>0, what are the factors? Explain.Select the correct answer below and, if necessary, fill in the answer box to complete your choice.

O

D. The value of n can be any prime integer resulting in the distinct factors

(Use a comma to separate answers as needed.)

O E. The expression cannot be factored for the given values of n.

Answers

Answer:

A. The value of n can be any positive integer resulting in the same factor

Step-by-step explanation:

Given

x^2 + 2xn + n^2 --- the right expression

n > 0

Required

Possible values of n

x^2 + 2xn + n^2

Expand

x^2 + 2xn + n^2 = x^2 + xn+xn + n^2

Factorize

x^2 + 2xn + n^2 = x(x + n)+n(x + n)

Factor out x + n

x^2 + 2xn + n^2 = (x + n)(x + n)

From the expression above, we can see that the result has the same factor. This means that options (b), (d) and (e) are not possible

x^2 + 2xn + n^2 = (x + n)^2

The above also shows that n can take any positive value.

Hence: (a) is correct
