Big bertha tips the scales at 950 newtons. what is her mass?

Mass, m = 96.94 Kg

Explanation:

Given,

The weight of Big Bertha, W = 950 N

The acceleration due to gravity, g = 9.8 m/s²

The force acting on a body of mass is given by the relation,

                         F = W = m x g    newton

∴                       m = W/g

Substituting the given values in the above equation,

                         m = 950 N / 9.8 m/s²

                             = 96.94 Kg

Hence, the mass of Big Bertha is, m = 96.94 Kg

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
