a hose fills a hot tub at a rate of 3.59 gallons per minute. how many hours will it take to fill a 309 gallon hot tub​
iris [78.8K]

Answer:

about 1.43 hours.

Step-by-step explanation:

You can use your original equation to find how many minutes it takes to fill up the 309 gallon hot tub.

3.59x=309

x= how many minutes it takes to fill up a certain gallon.

Divide both sides by 3.59 to isolate x and you get x=86.0724234.

That is how many minutes it takes.

The question asks for how many hours, so that divide 86.0724234 by 60 since there are 60 minutes in an hour, and you get 1.43454039 or 1.43 hours.

There is also another way which is called dimensional analysis, but I don't know if you guys learned that yet.

Hope my answer helps!

Find the distance between (-7, -2) and (11,3). Write your answer to one decimal.<br> Your answer
scoray [572]

Answer:

<h3>The answer is 18.7 units</h3>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-7, -2) and (11,3).

The distance between them is

d =  \sqrt{( { - 7 - 11})^{2}  +  ({ - 2 - 3})^{2} }  \\  =  \sqrt{ ({ - 18})^{2}  + ( { - 5})^{2} }  \\  =  \sqrt{324 + 25}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \:  \\  =  \sqrt{349}  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 18.681541692... \:  \:  \:  \:  \:

We have the final answer as

<h3>18.7 units to the one decimal place</h3>

Hope this helps you
