Find the value of x in the isosceles triangle shown below.<br> 13<br> V13<br> 2

UNO [17]

Answer:

Step-by-step explanation:

use Pythagorean theorem:

a² + b² = c²

where a = 2

b = x/2

c = √13

<u>plugin values into the formula:</u>

2² + (x/2)² = (√13)²

4² + <u>x² </u>= 13

16 + x² = 13 (4)

x² = 52 - 16

x = √36

x = 6

A water tank has 1,500 liters of water. It has a leak, losing 4 liters per minute. At the same time, a second tank has 300 liter

Darina [25.2K]

Let $t$ be the number of minutes.

The first tank starts with 1500 liters, and loses 4 liters per minute, so after $t$ minutes there will be

$1500-4t$

liters of water.

The second tank is filled at 6 liters per second, i.e.

$6\times 60=360$ liters per minute.

So, there will be

$300+360t$

liters of water in the second tank after $t$ minutes.

The two quantities will be equal when

$1500-4t=300+360t \iff 1200=364t \iff t=\dfrac{1200}{364}\approx 3.3$

so, approximately, after 3.3 minutes.
