Let
x-->volume of white vinegar you need to add to the mixture (measured in cups)
<span>then
the amount of the pure vinegar in the mixture will be -----> (10*0.1 + x) cups
t</span>he volume of liquid will be ---------> 10 + x
the concentration equation is-------> [(10*0.1 + x)/(10+x)]=0.50<span>multiply both sides by (10+x) and then simplify
</span>(10*0.1 + x)=(10+x)*0.50-----------> 1+x=5+0.50x-------> 0.50x=4
x=8
the answer is
<span>you need to add 8 of a cup of the pure vinegar to the mixture</span>
The perimeter of the triangle is : 12.6.
This result is obtain by the use of triangle perimeter formula :
Where : a is the distance between the points A and B
b is the distance between the points B and C
c is the distance between the points C and A
A=2*π*r*h+2*π*r^2
r = 16/2 = 8
using 3.14 for π since you don't say what to use
2x3.14x8x10 = 502.4
2x3.14x8^2 = 401.92
401.92 + 502.4 = 904.32 cubic ft.
