A Plan for Problem Solving

1.How many more miles of trails are

there than miles of shoreline in Crater

Lake National Park?

2.How many miles is it from Klamath

Falls to Crater Lake National Park?

3.SPORTSJasmine swims 12 laps every

afternoon, Monday through Friday.

How many laps does she swim in one

week?

4.SPORTSSamantha can run one mile in

8 minutes. At this rate, how long will it

take for her to run 5 miles?

5.SPORTSOn a certain day, 525 people

signed up to play softball. If 15 players are assigned to each team, how many teams can be formed?

6.PATTERNSComplete the pattern: 5, 7,

10, 14, ___, ___, ___

7.SHOPPINGJosita received $50 as a gift.

She plans to buy two cassette tapes

that cost $9 each and a headphone set that costs $25. How much money will she have left?

8.BUS SCHEDULEA bus stops at the

corner of Elm Street and Oak Street every half hour between 9 A.M. and

3 P.M. and every 15 minutes between

Prime Factors

Chapter 12Course 1

Copyright © Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc. 1-2 ANIMALSFor Exercises 1-3, use the table that shows the height and weight of caribou.

1.Which animal heights and weights are

prime numbers?

2.Write the weight of caribou cows in

kilograms as a prime factorization.

3.ANIMALSCaribou calves weigh about

13 pounds at birth. Tell whether this

weight is a prime or a composite number.

4.SPEEDA wildlife biologist once found a

caribou traveling at 37 miles per hour.

Tell whether this speed is a prime or

composite number. Explain.

5.GEOMETRYTo find the area of a floor,

you can multiply its length times its width. The measure of the area of a floor is 49. Find the most likely length and width of the room.

6.GEOMETRYTo find the volume of a box,

you can multiply its height, width, and length. The measure of the volume of a box is 70. Find its possible dimensions.
