Answer:

<em>$120</em>

Step-by-step explanation:

40% of the earnings is spent on rent.

The earnings is an unknown, so we call it x.

The rent is $800, so 40% of x equals $800.

40% * x = 800

0.4x = 800

x = 800/0.4

x = 2000

She earns $2000 per month.

After paying rent, the remaining amount is

$2000 - $800 = $1200

She spends 10% of the remaining amount on entertainment.

10% of $1200 = 10% * $1200 = 0.1 * $1200 = $120

Is it possible to find an edge length that would be perfect for a cube with a volume of 30 cubic units . Please explain
siniylev [52]
Volume of cube = (Side)^3
=>  30    = (Side)^3

So, Side  = \sqrt[3]{30}

Side = 3.107232......... and goes on.

Cube root of 30 is not a natural number or a terminating decimal number.
It is a non-terminating decimal number. So, physically it is not possible to find an edge length that will give volume 30 cubic units

Can you help please?? ​
romanna [79]

Step-by-step explanation:

this relation is not a function cuz each x pair (domian) has only one image in y pair (codomain) so we will have all the ×-axis pairs meeting with y-axis in only one point as they have one image as this is the rule of having a function so what in front of us the positive part of x-axis has two images in y-axis

u can knew it by another way draw a vertical line and if it meets in two point or more than one then the relation is not a function s o if we draw a vertical line in the right part of the graph it will meats in two points then not a function

the domain is all the pairs of this relation taken in x-axis which are [0,infinity[ and range is the y-axis images if the fomain in x-axis which are ]-infinity, infinity[
