Explanation: As Mark tossed six balls while playing a number game and that three balls landed in one section, and three balls landed in one section, and three balls landed in another section. Since his score is greater than one hundred thousand, which means that three of the balls landed in the section of 100,000 this will make the score 300,000. If the other three balls, landed in the section of 10,000 this will make the score of three balls to be 30,000. Therefore Mark’s score will be 300,000+30,000= 330,000.

Question 16.
b. How can you use what you know about place value to find what Mark’s score could be?

Answer: To find Mark’s score we will see where the ball will be landed. If the ball is landed in the 100,000 section then the score will be 100,000 and if the ball is landed in the 10,000 section then the score will be 10,000.

Question 16.
Rachael rounded 16,473 to the nearest hundred. Then she rounded her answer to the nearest thousand. What is the final number?

Answer: 17,000.

Explanation: When we round a number to the nearest we check the tens place digit, if the digit is less than 5 then the number is rounded to the previous hundred while if it is 5 or more than 5 then the number is rounded to the next hundred. As tens place digit is 7, so
16,473= 16,500. And when we need to round the number to the nearest thousand and will check the hundred place digit which is 5. So when 16,500 is rounded off to the nearest thousand the value will be 17,000.

How will I use the information?

Answer: We can draw a diagram or use a bar model to help me find how many feet the ballons traveled during the second trip.

Explanation: As hot air balloon traveled a distance of 5,110 feet in the first trip and 850 more in the second trip, so the second trip is 5,110+850= 5,960 feet. So, the balloon traveled 5,960 feet during the second trip.

Question 4.
How far did it travel during the second trip? And
______ feet

Answer: The ballon traveled 5,960 feet during the second trip.

Explanation: As hot air balloon traveled a distance of 5,110 feet in the first trip and 850 more in the second trip, so the second trip is 5,110+850= 5,960 feet. So, the balloon traveled 5,960 feet during the second trip.

Question 5.
Is your answer reasonable? Explain how you know.

Answer: Yes, the answer is reasonable.

Explanation: As 5,960 feet is reasonable because 5,000+1,000= 6,000 and 5,960 is close to 6,000. Since addition and subtraction are inverse operations, we can subtract 850 from the sum to see if we get 5,110.
