To fill:
6 hours  = 1 tank
1 hour = 1/6 tank

To drain:
It takes 4 times as long, therefore 4 x 6 = 24
24 hours = 1 tank
1hour = 1/24 tank

If both pipes are open 
1 hour = 1/6 - 1/24 = 1/8 tank
1/8 tank = 1 hour
8/8 tank = 1 x 8 hour
1full tank = 8 hours

1/n^2 and n^-2 are the same, and 16 and 1/16 definitely aren’t the same 4^-2 is just -4 * -4, and because negative * negative = positive, that adds up to being 16.

The answer is 1/16.

sattari [20]

Answer:

117

Step-by-step explanation:

Okay, the problem is asking that we find the hypotenuse of this triangle (AKA, the lake.)

a²+b²=c²

A= 75

B= 90

C is always the hypotenuse.

75²+90²= c²

5,625+8,100= 13,725

√13,725= 117.15374513859981591194584103639

To the nearest whole number: 117

To the nearest tenth: 117.2

Hope this helps!
