Ella intends to paint the floor area with hardwearing floor paint.
plan of storeroom - scale 1: 50
ella has a tin of floor paint that will cover up to 18 m².
ella thinks this will be enough paint to give the floor 2 coats of paint.
is she correct?

So he has to paint 255 m from the 280 m of paint he has

First divide 255/280 to give you a decimal

You should get .9107

Since this is in decimal form (out of 1) you want to get percentage which is out of 100 you multiply by 100

So .9107 times 100

This gives you the percentage which is

91.07%

Now it says round to 1 decimal so it would be

91.1%

Step-by-step explanation:

Latex floor paint is great for interior concrete floors but it is not suitable for high tire-traffic areas. Use a durable, oil-based epoxy paint that has been formulated to withstand the abuse of automobile traffic when painting garage floors.

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!
