Using the product rule
xCos(y)dy/dx + sin(y) + ycos(x)+sin(x)dy/dx = 0
xcosydy/dx + sin(x)dy/dx = -sin(y) - ycos(x)
(xcos(y) + sin(x))dy/dx = -sin(y) - ycos(x)
dy/dx = [-sin(y) - ycos(x)]/ {xcos(y) + sin(x)}
<span>16 walls in 40 hours
3 walls in h hours
16/40 = 3/h
16h = 40(3)
16h = 120
h=120/16
h=7.5
answer: </span><span>3 walls in 7.5 hours</span>
Answer:
270°
Step-by-step explanation:
In a circle graph, the total angle would be 360°. You already know how much of the circle graph is apple juice, so you can find the angle of apple juice out of the entire circle graph.
Angle of apple juice section = × 360°
= 270°
