The proportion would be -
12 / 150 = x / 225.
That is, 12 per 150, x amount per 225
To solve this proportion, you can cross multiply (multiply the values diagonally) -
12 / 150 = x /225
150x = 12(225)
150x = 2700
x = 18
18 vials are required to treat 225 people.
Hope this helps! (:
The answer is the first one:
bc its not growing by a (-)1/2 and the 3rd one just doesnt make sense
The quadrilateral ABCD is an isosceles trapezoid, and the length of AC for the quadrilateral is 19 feet
<h3>How to determine the
length of AC?</h3>
The quadrilateral ABCD is an isosceles trapezoid
This means that:
- Opposite sides are equal
- The diagonals are also equal
From the above highlights, we have:
AC = 7ft + 12ft
Evaluate the sum
AC = 19 ft
Hence, the length of AC for the quadrilateral is 19 feet

Answer: The answer is either c or d i hope this helps
P.S I'd choose c
(20 + 22 + 17) - 7 - 12 - (9 - x) = 37;
59 - 19 - 9 + x = 37;
31 + x = 37;
x = C) 6
