How deep is a well that takes eight cranks on the six- inch diameter windlass to raise the bucket?

Nookie1986 [14]

In order to answer this, you would need to find the circumference of the windlass. This would represent the distance of one rotation. When you know the distance of one rotation, you would then multiply it by eight for all eight Kranks. This is knowing each crank is a complete turn. Here is the formula C= pi times the diameter. So, 3.14 x 7 is 18.84 inches for 1 crank. 18.84 inches times 8 equals 150.72 inches. This is an approximation because pi is an approximation.

I am thinking of a number. My number is between 20 and 30 My number and 12 have only one common factor. What number could I be t

zhannawk [14.2K]

Answer:

21, 22 and 26

Step-by-step explanation:

To answer this question first we need to know which are the factors of 12:

$12= 2^2(3)$

So, now, we need 3 numbers that are <u>between 20 and 30 and that only have one common factor with 12</u>, in other words, they need to have just a 2 or a 3 in their factorization.

Let's take number 21:

$21= (7)(3)$ , we can see that 21 only has a 3 and a prime so therefore it has only one common factor with 12

Now, let's take the number 22,

$22=11 (2)$ , thus since 22 has a 2 and a prime, it has only one common factor with 12.

Now, let's take the number 26

$26= 13 (2)$ , thus, since 26 has a 2 and a prime, it has only one common factor with 12.

Thus, the three possible answers are 21, 22 and 26
