Answer:
hb ≈ 7.06cm
Step-by-step explanation:
Using the formulas:
A=hbb
2
A=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving for <em>hb</em>
hb=﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4
2b=﹣154+2·(15·17)2+2·(15·8)2﹣174+2·(17·8)2﹣84
2·17
≈7.05882cm

Answer:
22
Step-by-step explanation:
Let X be the time for only a small drain, the work completed would be unity.
The small drain has been open for a total of 11 hours, one hour next to the large one, and 10 hours alone.
We have that large drainage can accomplish this in 2 hours.
We have the following system:
1/2 + 11 / x = 1
solving, we have:
11 / x = 1 - 1/2
11 / x = 1/2
x = 11 * 2
x = 22
I mean it would take a total of 22 hours for the small drain alone
