<span>Out of the choices given, the biconditional that is not a good definition is "a ray is a bisector of an angle if an only it splits the angle into two angles. Hope this helps!</span>
Answer:
Step-by-step explanation:
The ratio 19/25 is the same as 76/100, or 0.76.
Multiplying this by 100%, we get 76%, the percentage of questions answered correctly.
Subtracting 76% from 100% results in 24%, which is the percentage of questions not answered correctly.

(a) Let 
denote the amount of sugar in the tank at time 
. The tank starts with only pure water, so 
.
(b) Sugar flows in at a rate of
(0.07 kg/L) * (7 L/min) = 0.49 kg/min = 49/100 kg/min
and flows out at a rate of
(<em>A(t)</em>/1080 kg/L) * (7 L/min) = 7<em>A(t)</em>/1080 kg/min
so that the net rate of change of is governed by the ODE,
or
Multiply both sides by the integrating factor 
to condense the left side into the derivative of a product:
Integrate both sides:
Solve for :
Given that 
, we find
so that the amount of sugar at any time is
(c) As 
, the exponential term converges to 0 and we're left with
or 75.6 kg of sugar.
