If m ∝ 1/r3 and m = 1 when r = 2, find:
(a) m when r =4|
(b) r when m = 125Light travel at a speed v through rock of density d. v varies inversely as the square root of d
V = 3 when d =2.25. find v when d = 2.26

The larger of two number is 4 less than twice the smaller number. the sum is 41. find the numbers

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)
