Hope this helps. (i'm doing the same test lol)
Answer:
<h3>3 : 2 : 4</h3>
<h2>CALCULATIONS</h2>
<h3>Let;</h3>
<h3>Kofi's age = 9</h3>
<h3>kwaku's age = 2/3 *9 = 6 </h3>
<h3>Yaw's age = 2(6) = 12</h3>
<h3>ratio of ages = 9 : 6 : 12</h3>
<h3>Simplest form = 3 : 2 : 4</h3>
Answer:
19 gallons
Step-by-step explanation:
Let x gallons be the amount of water which should be added to 6 gallons of pure acid in order to obtain the 24% acid solution.
Amount of water = x gallons
Amount of pure acid = 6 gallons
Amount of acid solution = x + 6 gallons
Amount of acid in acid solution = 24%
So, there are 
gallons of acid in acid solution.
Hence,
Solve this equation. Multiply it by 100:
Answer:
B
Step-by-step explanation:
For cartesian to polar transformation,
x = rcosA , y = rsinA.
Put in the values in the given equation. And (cosA)^2 - (sinA)^2 = cos(2A)
The decimal equivalent of 1/18 is 0.05555
