Ok so we know that in ONE second, the dam releases 40000 gallons of water. In ONE minute, there are 60 seconds. Therefore...

1 second----------------40000 gallons
60 seconds--------------? ( this is what we're trying to find.

To get from 1 to 60, we multiplied by 60. Now we do it on the other side. 40000 times 60 is 2,400,000, so the rate in gallons per minute is 2,400,000 gallons per minute

Answer:

Water releases in 1 minute  = 2400000 gallons.

Step-by-step explanation:

Given  : One of the valves on the Hoover Dam releases 40000 gallons of water per second.

To find : what is the rate in gallons per minute.

Solution : We have given

Water releases in 1 second = 40000 gallons.

1 minute = 60 second.

Water releases in 60 second = 40000 * 60 gallons.

Water releases in 1 minute  = 2400000 gallons.

Therefore, Water releases in 1 minute  = 2400000 gallons.

Sami cuts out a rectangle that has a perimeter of 48 inches and a length of 13 inches.
ddd [48]

Answer:

Width is 11 inches

Step-by-step explanation:

I am not sure what the question is.  I think you might be looking for the width length.  The perimeter is the distance around a rectangle.  If the whole distance around is 48.  We have 2 lengths and 2 widths.  They tell us that the length is 13.  We have two lengths so the lengths add up to 26.  We can subtract that from 48 and that leaves us with 22 (48-26)  This is the total for the 2 widths.  Since the 2 widths are the same length we divide that number by 2 to get 11.

11 + 11+ 13 + 13 = 48

Number 6 part a &amp; b<br> Number 7<br> Please &amp; thank you
miv72 [106K]

Answer:

6- Part A: 750a+1200r=1000000

    Part B: 1065a+876r=1000000

Solution of the system: a\approx521.739\;\;\;\;b\approx507.246

Step-by-step explanation:

<u>Part A:</u>

In words, the equation is formed like this:

Total kg of Arabica + Total kg of Robusta = Total kg of coffee

Now, the total of each yield is calculated by the product of kg/hectare and number of hectares. Thus, the equation is:

750a+1200r=1000000

<u>Part B:</u>

In words:

Arabica's worth + Robusta's worth  = plantation worth

Each yield's worth is given by the product of the price per kg and the corresponding production. So, the equation is:

1.42(750a)+0.73(1200r)=1000000\\1065a+876r=1000000
