Answer:
It will be 8 meters long.
<span>let:
X = the distance of the bottom of the ladder from the wall at any time
dX/dt = rate of travel of the bottom of the ladder = 1.1 ft/sec
A = the angle of the ladder with the ground at anytime
dA/dt = rate of change of the angle in radians per second
X = 10 cos A
dX/dt= -10 sin A dA/dt = 1.1
dA/dt = -1.1/(10 sinA)
When X = 6; cosA = 6/10; sinA = 8/10
Therefore:
dA/dt = -1.1/(10 x 0.8) = -0.1375 radiant per second. </span>
R:b=5:6 and we are adding an equal amount of white as there is red and blue so:
r:b:w=5:6:11
This means that there is a multiple of 5+6+11=22 parts of the whole...
55L/22p=2.5L/p that means that each part is equal to 2.5L.
Since there are 5 red parts, Jake will need 5(2.5)=12.5L
So Jake will need 12.5 liters of red paint.
X = 37/22
