Answer:


Step-by-step explanation:

2 * L + 2 * W = 68  

2*L = 2* 9x = 9x + 9x  

2*W = 2*8x = 8x + 8x  

Since the perimeter is 68  

9x + 9x + 8x + 8x = 68

The Canadian side of Niagara Falls has a flow rate of 600,000 gallons per second. How many gallons of water flow over the falls
Nady [450]

36,000,000 gallons

<h3>Further explanation</h3>

<u>Given:</u>

The Canadian side of Niagara Falls has a flow rate of 600,000 gallons per second.

<u>Question:</u>

How many gallons of water flow over the falls in 1 minute?

<u>The Process:</u>

We will solve the problem of finding many gallons of water flow over the falls in one minute. This is related to unit conversions.

Let us look carefully.

  • Every second flows 600,000 gallons of water.
  • In one minute, or 60 seconds, water flows as much as:

\boxed{ \ = \frac{600,000 \ gallons}{1 \ second} \times 60 \ seconds \ }

  • The second unit is crossed out.
  • The total zero from the multiplication above is six, while the yield of 6 times 6 is 36, so the final result is 36,000,000.

\boxed{ \ 600,000 \ gallons \times 60 = 36,000,000 \ gallons \ }

Thus, the amount of water flowing in a waterfall is \boxed{\boxed{ \ 36,000,000 \ gallons \ }}
