Seite 69 - The radins of a circle is a straight line drawn from the centre to the circumference as LM—Fig. 63. The diameter of acirde is a straight line drawn through the centre, and terminated both ways at the circumference, as ALC. A chord is a straight line joining any two points of the circumference, as DE. The versed sine is a perpendicular joining the middle
Seite 19 - the square root of the numerator for a new numerator, and the square root of the denominator for a new denominator. If the fraction will not extract even, reduce it to a decimal and then extract the square root. To Extract the Cube Root
Seite 18 - Find a square number equal to or the next less than the left-hand period, and put the root of it in the quotient. Subtract this square from the left-hand period, and to the remainder bring down the next period for a dividend, and to the left hand of it write double the quotient for a divisor. Then consider what figure if annexed to the divisor and the
Seite 66 - To find the base of a right-angle triangle when the perpendicular and the hypothenuse are given—Fig. 60. Subtract the square of the perpendicular from the square of the hypothenuse, the square root of the difference is equal to the length of the base. Base=i/Hypotenuse 2 —Perpendicular 2 or B=v / C 2 —H
Seite 67 - 61. From half the sum of the three sides of the triangle, subtract each side severally. Multiply the half sum and the three remainders together and twice the square root of the result divided by the base of the triangle will be the height of the perpendicular.
Seite 60 - the base by the perpendicular height. Parallelogram : Area = DXH To find the area of a trapezoid—Fig. 45. Multiply half the sum of the two parallel sides by the perpendicular distance between the sides.
Seite 15 - above it. Example : From 97.378 take 46.4972 50.8808 Answer. Multiplication of Decimals. Multiply the factors together, as in whole numbers, then point off from the product as many decimal places as there are in both factors, supplying any deficiency by .annexing ciphers to the left hand.

Seite 123 - of water one degree is called the specific heat of the substance. The specific heat of bodies varies very considerably, as will be seen from the following table: Water=1.000. Wrought Iron=0.113 Lead=0.031 Cast Iron=0.130 Copper=0.100 Mercury=0.333
Seite 123 - Thus, convert 158 degrees Fahrenheit to degrees Centigrade. Then (158—32) | = 70 degrees Centigrade. Or, to convert degrees Centigrade into degrees Fahrenheit: Multiply by 9, divide by 5, and add 32. Thus, convert 70 degrees Centigrade into degrees Fahrenheit. Then (70X
