Answer: it should be -8
From given picture we see that there is an altidude drawn from vertex W to the side KS.
We usually find altitudes of the triangle so that they meet at some point. That common point is known as orthocenter.
Hence choice A. Orthocenter is the correct answer.
We know that
<span>A large pump can drain an 80,000 gallon pool------------> in 3 hours
X gallons---------------------------------------------------------> in 2 hour
X=2*80000/3----------> 53333.33 gallons in 2 hour
therefore
</span><span>the smaller pump in two hours drain an [80000-53333.33]=26666.67 gallons
</span><span>
if the </span>smaller pump drain 26666.67 gallons-----------------> in 2 hours
<span> 80000 gallons------------------------------------------------> X
X=80000*2/26666.67------> 6 hours
the answer is
</span><span>the smaller pump to drain the pool by itself would take 6 hours</span><span>
</span><span>

Actual distance = distance on map x the scale:
3 inches x 15 miles per inch = 45 actual miles.
We know that
if <span>y is inversely proportional to x
then
y=k/x
where k is the constant of variation
so
for x=0.5 y=12
find the value of k
12=k/0.5-----> k=12*.5----> k=6
y=6/x
the rule is the following
y=6/x
