1. 60. This number is composite, because 60=2·2·3·5. Acoording to the rule given in task for this number you can have such possibilities:

  • 2 stacks with 30 towels at each;
  • 3 stacks with 20 towels at each;
  • 4 stacks with 15 towels at each;

  • 15 stacks with 4 towels at each;
  • 20 stacks with 3 towels at each;
  • 30 stacks with 2 towels at each.

2. 29 is prime number, because 29=1·29 (has only two trivial divisors). Then you cannot choose numbers of stacks and towels according to the given rule.

3. 37 is prime number, because 37=1·37 (has only two trivial divisors). Then you cannot choose numbers of stacks and towels according to the given rule.

4. 42=2·3·7 is composite number. Acoording to the rule given in task for this number you can have such possibilities:

  • 2 stacks with 21 towels at each;

c) 628 feet

Step-by-step explanation:

We are given the following in question:

Diameter of Ferris Wheel = 200 feet

a) Distance around Ferris wheel

The distance around Ferris wheel is given by the circumference of Ferris wheel.

b) Formula to calculate circumference

\text{Circumference} = \pi d

where d is the diameter of he wheel.

c) Distance traveled in one rotation

This will be given by the circumference of the Ferris wheel.

\text{Distance} = \pi d = 3.14\times 200 = 628\text{ feet}

Thus, the distance traveled in one rotation is 628 feet.
