A person pushes a 12. 5 kg lawn mower at constant speed with a force of 83. 0 n directed along the handle, which is at an angle of 45. 0∘ to the horizontal.

your answer is c! hope this : )

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

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
