Answer:
there are 6.45 or 6.5 square cm in one square inch
Step-by-step explanation:
Answer: It should be easy by showing the hint cause the thing is not fully explained.
Step-by-step explanation:

<span><span>V<span>Fluid</span></span>=<span><span>V<span>Antifreeze</span></span><span>%Antifreeze</span></span></span>

I want to find the amount of antifreeze in a 15 quart solution with 30% antifreeze
<span><span>V<span>Antifreeze</span></span>=15∗0.30</span> =18/4 quarts of antifreeze
Similarly, I want to find the amount of antifreeze in a 15 quart solution with 35% antifreeze first.
<span><span>V<span>Antifreeze</span></span>=15∗0.35</span> = 21/4 quarts of antifreeze
<span>the difference between 21/4 and 18/4 is 3/4 quarts, which is the amount of pure antifreeze I've added in.
</span><span>
SO the V_fluid I replaced with 3/4 quarts of antifreeze is (3/4)/ 0.35</span>
The measure of the exterior angle is equal to the sum of the remote interior angles. Overall the sum of all the angles of a triangle is 180 degrees.
As given in the question,
Two remote interior angles measure =
Hence, the exterior angle will be 99°
Option B is correct- The exterior angle measures 99˚.
