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 fill 1 meter of the aquarium it will take $\frac{9\times5}{3} = 15$ minutes (Dividing by 3 both the numerical values).

What is the distance between (2, -1) and (-1, -5) on the coordinate plane? 7 units 6 units 5 units 4 units

morpeh [17]

You can use the distance formula:
 $\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Plug in the given coordinates:
 $\sqrt{(-5-2)^2 + (-1+1)^2}$

$\sqrt{(7)^2 + (0)^2}$

$\sqrt{49+0}$

$\sqrt{49}=7$

Final answer : 7units
