Answer:
32cm³
Step-by-step explanation:
the volume of a cone is
V
=
π
r
2
h

in this case, we can relate
h
and
r
as we know that the slope =
h
r
=

=

we can make the volume a formula in a single variable
V
=

(

=

differentiating wrt time, it follows that

Answer:
She should add 30 ounces of the 12% vinegar she should add to 40 ounces of the 5% vinegar to obtain the needed vinegar with an 8% acidity level.
Step-by-step explanation:
Let X be ounces of the 12% vinegar she should add to 40 ounces of the 5% vinegar to obtain the needed vinegar with an 8% acidity level.
We have the equation
when 8% acidity level is reached.
Solving the equation we have
X*0.12+2=0.08(X+40)=0.08X+3.2
That is 0.12X-0.08X=3.2-2=1.2
Finally 0.04X=1.2 and
X=30
C- 37 because it is adding 2 more to what it added everytime so it would be 26+11
