Seite 2 - Rule. — Multiply the whole number by the denominator of the fraction, add the numerator to the product and place the denominator under the result.
Seite 46 - A Right Angle is that which is made by one line perpendicular to another. Or when the angles on each side are equal to one another, they are right angles.
Seite 50 - The circumference of every circle is supposed to be divided into 360 equal parts, called degrees ; and each degree into 60 equal parts, called minutes ; and each minute into 60 equal parts, called seconds ; and these into thirds, &c.
Seite 285 - The areas of circles are to each other as the squares of their diameters.
Seite 58 - If a straight line be divided into any two parts, the square of the whole line is equal to the squares of the two parts, together with twice the rectangle contained by the parts.
Seite 72 - To make a Square Equal to the Difference of two Given Squares. LET AB and AC, taken in the same straight line, be equal to the sides of the two given squares. — From the centre A, with the distance AB, describe a circle ; and make CD perpendicular to AB...
Seite xx - Multiply the numerators together for a new numerator, and the denominators together for a new denominator.
Seite xix - Hence the usual rule to reduce fractions to a common denominator : Multiply each numerator by all the denominators except its own for new numerators, and all the denominators together for the common denominator.
Seite 293 - The velocity in feet per minute should be ninetyeight times the square root of the length of the stroko in feet. The area of the steam passages will be as 4800 is to the velocity in feet per minute, so is the area of the cylinder to the area of the steam passage.
