Σελίδα 38 - MOMENTUM, from moveo, to move ; the product of the numbers which represent the quantity of matter and the Velocity of a body, is called its momentum or quantity of motion. MUCILAGINOUS ; resembling mucilage or gum. MULTIPLE, from multiplico, to render manifold ; a quantity is said to be a multiple of another when it contains that other quantity a certain number of times without a remainder. N.
Σελίδα 103 - Prob. 7. Two persons draw prizes in a lottery, the difference of which is 120 dollars, and the greater is to the less, as the less to 10. What are the prizes 1 Prob.
Σελίδα 58 - Thus, in the case of 53361 (whose square root is a number consisting of three figures) ; since the square of the figure standing in the hundred's place cannot be found either in the last period...
Σελίδα 123 - If four quantities are proportional, the quotient of the first divided by the second, is equal to the quotient of the third divided by the fourth. (Alg. 364.) Thus, if a : b : : c : d, then |=|, and"=^.
Σελίδα 129 - If four magnitudes are proportional, the sum of the first and second is to their difference as the sum of the third and fourth is to their difference.
Σελίδα 58 - For the square of tens can give no figure in the first right hand period ; the square of hundreds can give no figure in the first two periods on the right ; and the square of the highest figure in the root can give no figure except in the first period on the left.
Σελίδα 1 - Notation. 1. Quantities whose values are known or determined, are generally expressed by the first letters of the Alphabet, a, b, c, d, &c. ; and unknown or undetermined quantities are commonly represented by the last letters of the Alphabet, x, y, z, &c.
Σελίδα 90 - The sum of those digits is 5 ; and if 9 be added to the number itself, the digits will be inverted.
Σελίδα 128 - IF magnitudes, taken separately, be proportionals, they shall also be proportionals when taken jointly, that is, if the first be to the second, as the third to the fourth, the first and second together shall be to the second, as the third and fourth together to the fourth...
