TRUE HOPE THIS HELPS BC I DONT REALLY UNDERSTAND BUT I CAN SAY THAY AT LEAST TRIED
Answer:
one gallon of paints can cover about 2 walls.
(1/6) / (1/4) = x / 1....1/6 acre to 1/4 hr = x acres to 1 hr
cross multiply because this is a proportion
(1/4)(x) = (1/6)(1)
1/4x = 1/6
x = 1/6 * 4/1
x = 4/6 which reduces to 2/3....so she can mow 2/3 of an acre in 1 hr <=
Z° + 43° = 180°-------(linear angles)
z° = 180 - 43°
z = 137°
Hope this helps.
