It takes 9 minutes to fill an empty aquarium of a depth of 3/5 meters. What is the unit rate in minutes per meter?
GarryVolchara [31]

Answer:

<h2>The rate is 15 minutes per meter.</h2>

Step-by-step explanation:

It takes 9 minutes to fill a depth of \frac{3}{5} meters.

Filling  \frac{3}{5} meters take 9 minutes time.

Filling 3 meters of the aquarium takes 5\times9 = 45 minutes time (Multiplying by 5 both the numbers).

In order to<u> fill 1 meter of the aquarium it will take </u>\frac{9\times5}{3} = 15<u> minutes</u> (Dividing by 3 both the numerical values).

Plz help! ASAP! What is the expression shown below
astra-53 [7]

we are given

\frac{1}{2} (\frac{3}{2} x+6x+1)-3x

step-1: Simplify expression inside parenthesis

we will combine like terms

so, firstly we will take common denominator

\frac{1}{2} (\frac{3}{2} x+\frac{2*6}{1*2}x+1)-3x

\frac{1}{2} (\frac{3x+12x}{2} +1)-3x

\frac{1}{2} (\frac{15x}{2} +1)-3x

step-2: Distribute 1/2 inside

=\frac{1}{2} *\frac{15x}{2} +1*\frac{1}{2}-3x

=\frac{15x}{4} +\frac{1}{2} -3x

step-3: Combine like terms

=\frac{15x}{4}+3x +\frac{1}{2}

We can find common denominator

=\frac{15x}{4}-\frac{4*3x}{4*1} +\frac{1}{2}

=\frac{15x}{4}-\frac{12x}{4} +\frac{1}{2}

=\frac{15x-12x}{4} +\frac{1}{2}

=\frac{3x}{4} +\frac{1}{2}

we can also write it as in mixed form

=\frac{3}{4}x +\frac{1}{2}

so, we will get

\frac{1}{2} (\frac{3}{2} x+6x+1)-3x=\frac{3}{4}x +\frac{1}{2}

Dmitry_Shevchenko [17]
You can say 1 and 7/11 is 18/11 and 2 and 1/2 is 5/2 so : 
18/11 ÷ 5/2  so 18/11 * 2/5 = 36/55 = 0.654 :)))
i hope this is helpful
