Which expression is equal to 5/(sqrt)11?

horrorfan [7]

Answer:

Option A is correct

the expression is equal to $\frac{5}{ \sqrt{11}}$ is $\frac{5\sqrt{11}} {11}$

Explanation:

Given expression is, $\frac{5}{ \sqrt{11}}$

Multiply and divide by the denominator by $\sqrt{11}$ in the given expression, we have,

$\frac{5}{\sqrt{11}} \times \frac{\sqrt{11}} { \sqrt{11}}$

$\frac{5 \cdot \sqrt{11}} {\sqrt{11} \cdot \sqrt{11}}$

use : $\sqrt{a}\cdot\sqrt{a}=(\sqrt{a} )^2 = a$

then;

$\frac{5\sqrt{11}} { (\sqrt{11})^2} =\frac{5\sqrt{11}} {11}$

Therefore, the expression is equal to $\frac{5}{ \sqrt{11}}$ is, $\frac{5\sqrt{11}} {11}$

A tank can be filled by one pump in 3.2 hours and by another pump in 80 minutes. A third pump can drain the tank in 2 hours and

Mademuasel [1]

Answer:

Rounding to the nearest minute, it would take 95 minutes, or 1 hour and 35 minutes.

Step-by-step explanation:

Let's convert each time to minutes:

3.2 hours = 192 minutes

80 minutes = 80 minutes

2 hr 20 min = 140 minutes

Next, let's find the least common multiple:

LCM(192, 80, 140) = 6720

So let's say the volume of the tank is 6720 units. The speed of each pump is therefore:

Pump 1 = 6720 units / 192 minutes = 35 units/minute

Pump 2 = 6720 units / 80 minutes = 84 units/minute

Pump 3 = -6720 units / 140 minutes = -48 units/minute

Their combined speed is:

35 + 84 − 48 = 71 units/minute

So the time to fill the tank is:

6720 units / (71 units/minute) = 94.65 minutes

Rounding to the nearest minute, it would take 95 minutes, or 1 hour and 35 minutes.
