Question

Apply the Strategy Determine whether each problem requires an estimate or an exact answer. Then solve. Mathematical . PRACTICE Model Math Michelann cut two lengths of rope. One was 32 inches long. The other was 49 inches long. Will she have enough rope for a project that needs 76 inches of rope? Explain. Mathematical 2. PRACTICEUse Number Sense The number 7 septillion has 24 zeros after it. The number 7 octillion has 27 zeros after it. How many zeros is that altogether? What is the difference between the number of zeros in 7 septillion and 7 thousand? Mathematical 3. PRACTICEL Justify Conclusions Three buses can carry a total of 180 students. Is there enough room on the 3 buses for 95 boys and 92 girls? Explain. 4. Mrs. Carpenter received a bill for car repairs. About how much was the oil change if the other repairs were $102? Lesson 3 P

Explanation / Answer

1) 32 +49 = 81

since 81 > 76

she will have enough rope for the project

2) total number of zeros = 24 + 27 = 51

difference in the number of zeros in septillon and thousand = 24-3 = 21

3) 95 +92 = 187

180 < 187

hence there is not enough room
