Page 215 - A Circle is a plane bounded by a curved line, called the circumference, every point of which is equally distant from a point •within, called the centre ; thus: 703. The Diameter of a circle is any straight line, as CD, passing through its centre and terminating at both ends in the circumference.
Page 72 - CIRCULAR MEASURE. 428. A Circle is a plane figure bounded by a curved line, all points of which are equally distant from a point within called the centre. 429. A Circumference is the line that bounds a circle. 430. A Degree is one of the 360 equal parts into which the circumference of a circle is supposed to be divided.
Page 95 - of $29600 = $3700, the required number. From these solutions we obtain the following rule for finding a number when a decimal part of it is given : 503. RULE.—Move the decimal point as many places to the right as there are places in the given decimal, annexing ciphers if necessary, and divide the result by the number expressed
Page 80 - IV.—To divide by 1O, 1OO, 1OOO, etc. Move the decimal point in the dividend as many places to the left as there are ciphers in the divisor, prefixing ciphers when necessary. Perform the division in the following: 1. 8736^-100. 4. 23.97—1000. 7. .54—100. 2.
Page 80 - V.—To divide where there are ciphers at the right of the divisor. Move the decimal point in the dividend as many places to the left as there are ciphers at the right of the divisor, prefixing ciphers when necessary (14O), and divide the result by the significant figures in the divisor (142). Perform the
Page 26 - 212. A Multiple of a number is a number that is exactly divisible by the given number. Thus, 24 is divisible by 8 ; hence, 24 is a multiple of 8. 213. A Common Multiple of two or more numbers is a number that is exactly divisible by each of them. Thus, 36 is
Page 38 - We reduce, as shown in (1), both multiplicand and multiplier to improper fractions. 2. We multiply, as shown in (2), the numerators together for the numerator of the product, and the denominators together for the denominators of the product (275), then reduce the result to a mixed number.
Page 31 - 239. A fraction is reduced to Lower Terms when its numerator and denominator are expressed by smaller numbers. Thus, A = f 240. A fraction is expressed in its Lowest Terms when its numerator and denominator are prime to each other. Thus,
Page 217 - half the sum of the three sides subtract each side separately. Multiply the half sum and the three remainders together ; the square root of the product is the area. 1. Find the area of a triangle whose sides are 15, 20, 25 feet.
Page 75 - of the distance on the earth's surface from the equator to the pole, is the base of the system. 441. The Primary or Principal Units of the system are the Meter, the Are (air), the Stere (stair), the Liter (leeter), and the Gram. All other units are multiples and sub-multiples of these. 443. The names of
