The formula of the area of the equilateral triangle:
The formula of the area of the rectangle:
The formula of the volume of the triangular prism:
12%=(3+10%*x)/(20+x)
x=30
add 30 pounds of the second alloy
Absolute value functions are v-shaped. I hthink the turning point you're referring to is the vertex. This is where the inside of the absolute value is zero.
f(x) = |x+2|
0 = x+2
-2 = x
vertex (-2,0)
I think the ratio is for for every 4 packs it cost 10 dollars so in all it would cost 30 dollars
