Explanation
Sam's score on the test was 90% because he got 18 out of 20 questions right. To calculate the percentage score, we divide the number of correct answers (18) by the total number of questions (20) and then multiply by 100. This gives us a score of 90%.

Explanation
One kilometer is equal to 1000 meters. This is a well-known conversion factor in the metric system.

Explanation
To calculate the speed needed to reach the airport by 12:45pm, we need to determine the time available for travel. If we leave at noon and need to reach the airport in 45 minutes, we have 45 minutes to cover a distance of 30 miles. To convert the time to hours, we divide 45 minutes by 60, which gives us 0.75 hours. To calculate the speed, we divide the distance (30 miles) by the time (0.75 hours), which equals 40 mph. Therefore, driving at a speed of 40 mph is required to reach the airport by 12:45pm.

Explanation
The area of a rectangle is calculated by multiplying the length and width of the rectangle. In this case, the length is 5 and the width is 3. So, the area of the rectangle would be 5 * 3 = 15.

Explanation
The word "difference" in math refers to the result obtained when two numbers are subtracted from each other. It represents the numerical distance between two quantities or values. Therefore, the correct answer is subtraction because it is the operation used to find the difference between two numbers.

Explanation
The word "quotient" in math refers to the result of a division operation. It represents the number of times one quantity is divisible by another. For example, in the division problem 10 ÷ 2 = 5, the quotient is 5. Therefore, the correct answer is Division.

Explanation
There are 24 hours in a day, and a week consists of 7 days. To calculate the total number of hours in a 7-day week, we multiply 24 by 7, which equals 168 hours. Therefore, the correct answer is 168 hours.

Explanation
Sam made $100 per week and received a 10% raise. To calculate the raise amount, we multiply $100 by 10% (which is 0.10), resulting in $10. Adding this raise amount to Sam's original salary, we get $100 + $10 = $110. Therefore, Sam will make $110 after the raise.

Explanation
The product of 2 and 8 is 16.

Explanation
The quotient of 49 divided by 7 is 7 because when you divide 49 by 7, you get 7 as the result.

Explanation
A straight line is the shortest distance between two points and it forms a 180-degree angle. This is because a full circle is 360 degrees, and a straight line cuts the circle in half, resulting in an angle measure of 180 degrees.

Explanation
If one pizza costs $4, then the cost of 12 pizzas can be calculated by multiplying the cost of one pizza by the number of pizzas. Therefore, 12 pizzas will cost 12 * $4 = $48.
