We know that
<span>when a circle is divided into four equal parts, we will get 4 right angles
</span>so
360°/4=90° each part
see the attached figure to better understand the problem
Answer: 19 mins
Step-by-step explanation:

The answer is 0.008a^3 because you would do 0.2 to the power of 3
15% of 20 gal = 0.15 * 20 gal = 3 gal, so the solution contains 3 gal of salt.
If we add <em>x</em> gal of water to the solution, we end up with (20 + <em>x</em>) gal of solution. We want the new mixture to have a concentration of 10%, or
10% of (20 + <em>x</em>) gal = 0.1 * (20 + <em>x</em>) gal = 2 + 0.1<em>x</em> gal
of salt.
The amount of salt in the tank hasn't changed. Solve for <em>x </em>:
2 + 0.1<em>x</em> = 3
0.1<em>x</em> = 1
<em>x</em> = 10 gal
