Let Keeton receive x votes.
Billy received 3 times more = 3*x = 3x
If all the 20 students voted, the total votes would be equal to x.
3x + x = 20
4x = 20
x = 20/4
x = 5
Since Billy received 3x = 3*5 = 15
Option C.
First you turn the % in to decimal .20
then you multiply .20 by 340=68.00
then you subtract 340.00-68.00=272.00
the final answer is 272.00 pages

(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.
Answer:
true!
Step-by-step explanation:
plug in 1.1
3 + 51(1.1) = 59.1
3 + 56.1 = 59.1
59.1=59.1
