Answer:

The slope is 1/3

Step-by-step explanation:

Take 2 points on the line, lets use (0,50) and (30,60)

x1 y1 x2 y2

Use slope formula:

y2 - y1 / x2 - x1

60 - 50 / 30 - 0

10 / 30

which can be simplified to:

1/3

factorise completely (x plus 2) Square - (x - 4) Square and hence find then value of 1000 Square minus 992 Square

tekilochka [14]

Answer:

$x^2+3x+8$

$15936$

Step-by-step explanation:

$\left(x+2\right)^2-\left(x-4\right)$

$\left(x+2\right)\left(x+2\right)-\left(x-4\right)$

$x^2+2x+2x+4-(x-4)$

$x^2+4x+4-\left(x-4\right)$

$x^2+4x+4-x+4$

$x^2+3x+8$

$1000^2-992^2$

$1000000-984064$

$15936$

A cubical water tank can contain 1000/125 cubic meters of water. Find the length of a side of the water tank.

Annette [7]

Given:

Volume of cubical tank = $\dfrac{1000}{125}$ cubic meters.

To find:

The length of a side of the water tank.

Solution:

The volume of a cubical tank is:

$V=a^3$

Where, a is the side length.

It is given that the volume of cubical tank is $\dfrac{1000}{125}$ cubic meters. So,

$a^3=\dfrac{1000}{125}$

$a^3=\dfrac{(10)^3}{5^3}$

Taking cube root on both sides, we get

$a=\dfrac{10}{5}$

$a=2$

Therefore, the length of a side of the water tank is 2 meters.
