Given: A prism with a Nonagon as base.
To find: When a cross section be a Decagon.
Nonagon is a polygon with 9 sides
Decagon is a polygon with 10 sides.
1). when a cross section is taken parallel to the base, the cross section will be Nonagon .i.e., it will be a 9 sided polygon.
2).when a cross section is taken perpendicular to the base, the cross section will be a rectangle.
3). when a slant cross section is taken .i.e., one with any angle other than 90° or 180° to the base. It will be a 10-sided polygon.

Answer:
9/320 gallons of water or 0.028125 gallons of water
Step-by-step explanation:
We are told in the question:
13 1/3 cup of salt = 1 cup of water.
6 cups of salt =
Cross Multiply
= 6 × 1/ 13 1/3
= 6 / 13 1/3
= 6 ÷ 40/3
= 6 × 3/40
= 18/40 cup of water.
= 9/20 cup of water.
16 cups of water = 1 gallon
9/20 cup of water =
= 9/20 × 1/16
= 9/20/ 16
= 9/20 ÷ 16
= 9/20 × 1/16
= 9/320 gallons of water or 0.028125 gallons of water
Therefore, 9/320 gallons of water or 0.028125 gallons of water is needed for 6 cups of salt
=
Final answer:
To make 6 cups of salt, 6/16 gallons of water are needed.
Explanation:
To determine how many gallons of water are needed for 6 cups of salt, we can use the proportion given in the recipe: 13 1 3 cups of salt for every cup of water. We can set up the proportion as 13 1 3 : 1 = 6 : x, where x represents the number of gallons of water needed. To solve for x, we can cross multiply and divide: (13 1 3)(x) = (6)(1), which simplifies to x = 6 * 1 / 13 1 3 = 6 / 13 1 3. To convert this fraction to a mixed number, we can use division: 6 ÷ 13 = 0 with a remainder of 6. Therefore, there are 0 whole gallons of water and 6 cups, or 6/16 gallons, of water needed.

Final answer:
Cindy's argument is incorrect. 1/3 is a rational number because it can be expressed as the ratio of two integers. The fact that the decimal representation of 1/3 does not terminate does not make it irrational.
Explanation:
Cindy's argument is incorrect. A fraction is considered irrational if it cannot be expressed as the ratio of two integers. In the case of 1/3, it can be expressed as the division of the integer 1 by the integer 3, so it is a rational number. The fact that the decimal representation of 1/3 (0.333...) does not terminate does not make it irrational. Irrational numbers are decimal numbers that do not repeat or terminate, such as π (pi) and √2 (the square root of 2).
