Answer:
Step-by-step explanation:
Set this up as a proportion with the ratios being
If there is a 2:5 ratio of vinegar to oil, that ratio looks like this:
and if we are looking for how much oil, x, is needed for 20 ml of vinegar, then that ratio completes the proportion:

Answer:
133 ft
Step-by-step explanation:
Given in the question,
length of the rectangle = 31 ft
width of the rectangle= 20 ft
diameter of semicircle = 20 ft
radius of semicircle = 20/2 ft = 10 ft
Formula to use:
<h3>perimeter of rectangle + perimeter of semicircle</h3>
perimeter of rectangle = 2(l+w)
perimeter of semicircle = 1/2(2πr)
Plug values in the formula above
2(31 + 20) + 3.14(10)
133.4 ft
≈ 133 ft
