Cut out 18%
100=all,
all-cut out=remaining
100-18=82
4hrs 20mins=240+20mins=260mins
82% of 260 is 0.82*20=213.2=3 hours and 33.2 minutes
he can runi s 3 hours and 33.2 minutes
Your answer would be 5x over 3

For example
Here given phrase is
twice the sum of a number cubed and nine
let number be r
We can write it as
Now evaluating it for r=3
Now we can simplify it as

Step-by-step explanation:
measure all the sides then multiply you will get the answer
The first thing to do is find the rectangular warehouse area.
We have then:
A = (12) * (18) = 216
A = 216 m ^ 2
We now look for the area of each acoustic tile square:
A '= (1) ^ 2 = 1
A '= 1 m ^ 2
We look for acoustic tile squares number:
N = (A) / (A ')
N = (216) / (1)
N = 216
Finally we look for the total weight:
W = (1/4) * (216)
W = 54 Kg
Answer:
The total weight of the tile required to cover the ceiling is:
W = 54 Kg
