Find the value of: 26. 13.401 × 6.754. 27. 3.97348.2083. 28. .066665 ÷ .9432. 472. Value, composition and weight of U. S. coins. 473. The names and values of the English coins are as follows: The gold coins are the sovereign (= £1), half sovereign (= 10 s.), guinea (= 21 s.), and half-guinea (= 10 s. 6 d.) The silver coins are the crown (= 5 s.), the half-crown (= 2 s. 6 d.), the florin (= 2 s.), the shilling, and the six-penny, four-penny, and three-penny pieces. The penny, half-penny, and farthing are the copper coins. A knot, used for measuring distances at sea, is equivalent to a nautical mile. The weight of a bushel of certain articles is as follows: NOTE.-In Louisiana the weight of a bushel of oats, barley and The old French linear and land measure is still partly used in Louisiana, and in other French settlements of the United States. 1024 sq. toises = 1 sq. arpent. The French foot equals 12.79 English inches. The arpent is the old French name for acre, and is equal to about of an English acre. DIFFERENCE BETWEEN DATES. 475. There are four methods of finding the time between two dates. To illustrate them let it be required to find the time from June 25, 1886, to Nov. 3, 1889. Explanation. I first find the number of whole years, aud then the number of days, giving 3 yr. 131 da. EXERCISE CXII Find by each method the time: 1. From Jan. 29, 1882, to Aug. 15, 1884. 2. From June 18, 1863, to March 1, 1868. NOTES.-1. Bankers and other accountants generally use "Time Tables," which give the exact number of days between any two dates less than a year apart, and "Interest Tables" which give the interest of $1 at different rates for years, months, and days. These tables are designed for use in business, and not for pupils in the schools. 2. It is well to observe that the method of expressing time is not in accordance with the ordinary principles of Arithmetical Notation. In general, where no sign is written, plus is understood. Thus, 375 means 300 + 70 + 5; 4 gal. 3 qt. 1 pt. means 4 gal. + 3 qt. + 1 pt. But 1889 yr. 6 mo. 5 da. 7 hr. 13 min. does not mean 1889 yr. + 6 mo. + etc. It means 7 hr. + 13 min. of the 5th da. of the 6th mo. of the 1889th yr., or 1888 yr. + 5 mo. + 4 da. + 7 hr.+ 13 min. 477. The following table shows the legal and allowable rates of interest in the several States: NOTE. When the per cent of interest is not mentioned in the note or contract, the first column gives the per cent that may be collected by law. If stipulated in the note, a per cent of interest as high as that in the second column may be collected. 478. To compute interest by cancellation. Find the interest of $142 for 2 yr. 3 mo. 18 da., at 8%. Operation. 142 9.2 27.6 12 3 Explanation.—I draw a vertical line; on the left I place the principal, time expressed in months and decimal of a month and the rate; on the right I place 12, and proceeding according to the rule of cancellation, obtain $26.528. For exercises, let the student solve the examples on page 26.528. |
