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>

Answer:triangles 20 12 28 and15 9 21
Step-by-step explanation:
After Martha ate 1/4 of the pie there is 3/4 left.
Edwin ate 1/4 of 3/4.
so multiply 1/4 and 3/4 ---> 1/4*3/4=3/16
to find the leftover subtract 3/16 from 3/4
3/4-3/16
12/16-3/16=9/16
Christina ate 1/3 of 9/16
multiply 1/3 by 9/16
1/3*9/16=3/16
find the leftover by subtracting 3/16 from 9/16
9/16-3/16=6/16
divide by 2
3/8
