Rational numbers
Rational numbers can be expressed as fractions p/q where p and q are integers and q is not equal to 0. Rational numbers have several properties including:
1) Closure under addition, subtraction, multiplication, and division. For example, the sum or product of two rational numbers is also a rational number.
2) Commutativity and associativity for addition and multiplication. For example, a + b = b + a for rational numbers a and b.
3) The distributive property relating multiplication and addition/subtraction. For example, a(b + c) = ab + ac.
4) Zero is the additive identity and one is the multiplicative identity. For example

The document discusses evaluating expressions containing exponents and properties used to simplify expressions:
1. Exponents indicate the number of times a base is used as a factor. Expressions are evaluated by writing them as repeated multiplication or using a base and exponent.
2. The order of operations determines the order to perform calculations in an expression. Exponents, multiplication and division are performed before addition and subtraction.
3. Properties like the distributive property allow expressions to be simplified, such as distributing multiplication over addition or subtraction.

Okay, let's think through this step-by-step:
* For 1 guest, you need 2 bags of spaghetti
* For 2 guests, you need 5 bags of spaghetti
* For 3 guests, you need 8 bags of spaghetti
Let's call the number of guests n. Then we can write:
For n = 1 guest, bags of spaghetti = 2
For n = 2 guests, bags of spaghetti = 5
For n = 3 guests, bags of spaghetti = 8
Looking at the pattern, it seems the number of bags increases by 3 each time the number of guests increases by 1.
So the rule is:
Number of bags of spaghetti

The document provides instructions to sketch and calculate the volumes of different shapes, including a rectangular prism with dimensions of 3 mm by 5 mm by 15 mm, a cylinder with a diameter of 2.6 m and height of 3.5 m, a rectangular prism with dimensions of 6 inches by 6 inches by 9 inches, and a cylinder with a radius of 3 yards and height of 10 yards. It also gives problems to find the height of a rectangular prism with given length, width, and volume, and to find the radius and height of cylinders with given dimensions and volumes.
04.08.10 applications of volume and surface area
The document contains 4 applications that use surface area and volume concepts:
1) Finding the height of an aquarium tank given its dimensions and volume.
2) Comparing the surface area and volume of a can and box to determine which holds more juice.
3) Calculating the surface area of a gift to see if a sheet of wrapping paper is large enough.
4) Determining which pizza sauce jar is a better buy based on price and volume.
04.07.10 more volume
The document provides instructions for calculating the volumes of different shapes, including a rectangular prism and cylinder. It asks the reader to first predict which solids have the greatest and least volumes without calculations. It then has the reader measure dimensions of different solids to calculate their actual volumes and rank them. Finally, it gives two word problems to find heights using given lengths, widths, radii and volumes.
