A lunch menu has 3 beverage selections: water, juice and milk. The menu also offers 2 sandwich selections: turkey and peanut butter. How many different meals of one beverage and one sandwich are possible?

Explanation
There are 3 options for the beverage selection (water, juice, milk) and 2 options for the sandwich selection (turkey, peanut butter). To find the number of different meals, we multiply the number of options for each selection together: 3 options for the beverage selection multiplied by 2 options for the sandwich selection equals 6 different meals. Therefore, there are 6 different meals of one beverage and one sandwich possible.

Inez has a toy car collection. She has 55 red cars, 67 blue cars and 123 orange cars. How many cars does she have in all?

Explanation
The question asks for the total number of cars that Inez has in her collection. To find the answer, we add the number of red cars (55), blue cars (67), and orange cars (123) together. This gives us a total of 245 cars.

A gallon contains 128 ounces. Paul wants to divide 3 gallons of apple cider equally among 2 dozen friends at his party. How many ounces of apple cider will each friend receive?

Explanation
Since a gallon contains 128 ounces, 3 gallons would contain a total of 3 * 128 = 384 ounces of apple cider. If Paul wants to divide this equally among 2 dozen friends, he would need to divide 384 by 24 (as 2 dozen is equal to 24). Therefore, each friend would receive 16 ounces of apple cider.

Luis is tiling the rectangular floor of a room measuring 8 feet 6 inches by 12 feet. How many 6 inch by 6 inch tiles will Luis need to tile the floor without overlapping?
- A.
  
  408
- B.
  
  287
- C.
  
  204
- D.
  
  172
Correct Answer
A. 408

Explanation
To find the number of tiles needed, we need to calculate the area of the rectangular floor and then divide it by the area of each tile. The rectangular floor measures 8 feet 6 inches by 12 feet, which is equivalent to 102 inches by 144 inches. The area of the floor is therefore 102 inches * 144 inches = 14,688 square inches. Each tile measures 6 inches by 6 inches, which is equivalent to 36 square inches. Dividing the area of the floor by the area of each tile gives us 14,688 square inches / 36 square inches = 408 tiles needed to tile the floor without overlapping.

A student places Beaker X containing one liter of water on a burner. The student places Beaker Y containing one liter of water in the freezer. What is occurring in the samples?
- A.
  
  Beaker X: phase change Beaker Y: chemical change
- B.
  
  Beaker X: chemical reaction Beaker Y: physical change
- C.
  
  Beaker X: increasing kinetic energy Beaker Y: decreasing kinetic energy
- D.
  
  Beaker X: cold is moving out of the water Beaker Y: cold is moving into the water
Correct Answer
C. Beaker X: increasing kinetic energy Beaker Y: decreasing kinetic energy

Explanation
In Beaker X, the water is being heated on the burner, which causes an increase in kinetic energy of the water molecules. This is a physical change as the water is transitioning from a liquid to a gas state (phase change). In Beaker Y, the water is being cooled in the freezer, causing a decrease in kinetic energy of the water molecules. This is also a physical change as the water is transitioning from a liquid to a solid state (phase change).
