CARPETING

ORAL EXERCISE

1. How many strips of 3 yd. carpet are needed for a room 18 ft. wide, not allowing for matching the pattern?

2. A carpet has an 18-in. pattern? Will there be any loss in matching if the strips are 15 ft. long? 14 ft. long?

WRITTEN EXERCISE

1. How many yards of carpet, 9-in. pattern, are needed for a room 11 ft. 3 in. wide and 12 ft. long, the carpet being 27 in. wide? Draw a plan showing how the strips lie.

2. How many yards of carpet, 1-yd. pattern, are needed for a room 13 ft. 6 in. wide and 16 ft. long, the carpet being 27 in. wide? How much is wasted on each strip (except the first, with which the others must match)? Draw a plan.

Show that no allowance is ever necessary for the first strip.

Find how many yards of carpet are needed for the following, allowing for matching each strip (except the first), as indicated:

3. 18 ft. by 20 ft., 27-in. carpet, allowing 9 in.

4. 16 ft. by 18 ft., 27-in. carpet, allowing

yd.

5. 14 ft. by 15 ft., 36-in. carpet, allowing yd.

Find the cost for carpeting these rooms with 27-in. carpet, allowing 4 inches on each strip (except the first), @ $1.20 a yard:

6. 18 ft. by 15 ft.

8. 14 ft. 3 in. by 18 ft.

7. 18 ft. by 17 ft. 6 in. 9. 13 ft. by 16 ft. 3 in.

326. Papering. The standard width for estimating wall paper is 18 in., although it varies greatly. A single roll is considered to contain 8 yd. of paper. In estimating, paper hangers usually count 3 rolls to 100 sq. ft. Fractional parts of rolls cannot be bought.

ORAL EXERCISE

1. What will the border for a room 16 ft. by 20 ft. cost, at 25 ct. a yard?

2. Estimate the cost of the paper for a ceiling 15 ft. by 20 ft., at 40 ct. a roll.

3. A room has nearly 500 sq. ft. of wall to be papered. Estimate the cost of the paper at 50 ct. a roll.

4. A plain wall 14 ft. long and 9 ft. high above the baseboard is to be papered. How many rolls should you allow?

WRITTEN EXERCISE

1. The walls of a room are 8 ft. 6 in. above the baseboard, and the total length of the four walls, allowing for openings, is 72 ft. Allowing 6 in. on each strip for matching, what will the paper cost at 40 ct. a roll?

2. How many rolls of plain paper will it take to cover the four sides of a room 12 ft. high, 25 ft. long, and 20 ft. wide, the paper being 24 in. wide, allowing 1 rolls for windows and doors? At 35 ct. a roll, what will it cost?

3. The walls of a room are to be papered with plain. paper worth 30 ct. a roll. They are 9 ft. high above the baseboard, and the total length of the four walls, allowing for windows and doors, is 60 ft. At the usual estimate, what will the paper cost?

LAYING OUT A GARDEN AND GROUNDS

WRITTEN EXERCISE

1. The house described on page 236 was built on a lot 100 ft. wide and 200 ft. deep. The owner took a piece 40 ft. by 80 ft. for vegetables, and one 60 ft. by 80 ft. for fruit. How many square feet

in each?

2. He planted a row of grapevines around the garden and four corners, 10 ft. apart. How many did he plant?

3. Across the fruit garden he set out 3 rows, 60 ft. long, of dwarf pears, 1 row of dwarf cherries, and 1 row of dwarf plums, putting the trees 10 ft. apart and 10 ft. from his neighbor's line. How many trees did he set out?

4. He set out a 60-ft. row of blackberry bushes, 3 ft. apart and 3 ft. from the fence; also 2 such rows of blackcaps and 2

of red raspberries. How many bushes did he set out? 5. He planted a bed of asparagus 4 ft. wide and 36 ft. long; 2 beds of parsnips and 2 of beets, each 1 ft. wide and 36 ft. long; 2 beds of tomatoes, and 2 of squash, each 3 ft. wide and 36 ft. long. What area did he give to each?

6. He planted shrubs about the lawn. These, with the walks, occupied 2200 sq. ft. How many square feet were

GENERAL BUSINESS APPLICATIONS

327. Our mining interests. We have frequently studied the greatest source of our national wealth, our farms.

Another source

we have seen to be our forests. Still another important one is our mines. The first (raw) product of our mines was, at the beginning of the century, worth about $800,000,000 a year, the metals produced were worth about $500,000,000, and the petroleum products alone were worth over $70,000,000. We think of our gold

output as valuable, but our copper is more so, our iron is three times as valuable, and our coal is worth. four times as much.

The most valuable product of our mines is coal, from which coke and gas are made, and which furnishes the chief power for our

WRITTEN EXERCISE

1. A short ton of bituminous (soft) coal contains 76.05% of carbon and 2.32% of ash. How many pounds are there of each?

2. If 2000 lb. of anthracite (hard) coal contain 1828 lb. of carbon, how much will 100 lb. contain? What is the per cent of carbon?

3. We mined 268 million tons of coal in a certain year when Great Britain mined 252 million tons. Our output

was what per cent greater than theirs?

4. If we manufacture $75,700,000 worth of gas a year, the coal and other material used costing 27% of this amount, how much does the material cost?

5. If Maryland produces 5.1 million tons of soft coal, worth at the mines $5,000,000, what is the value of Pennsylvania's output of 81.6 million tons, at the same average price per ton?

6. If we produce 226 million tons of bituminous coal, worth $1.05 a ton at the mines, and 30% as much anthracite, worth 60% more per ton, what is the total value of our annual coal product?

7. A Wilkesbarre (Pennsylvania) coal shaft is 1042 ft. deep, and the opening is 12 ft. by 51 ft. Supposing it to be rectangular, it represents the excavating of how many loads of earth, 1 cu. yd. to a load?

8. Near the bituminous mines are coke ovens where the coal is converted into coke by driving off the gas and moisture. We use 30 million tons of coal a year to make 19 million tons of coke. What is the loss per cent?

9. Of the 19 million

tons of coke produced, Pennsyl
