Answer: 5%
Step-by-step explanation:
Firstly, Convert metre to centimetre
100cm = 1m
Therefore,
4.5m = 450cm
If 450cm is X% of 90cm
That becomes :
450= X% × 90
450= 90X%
X% = 450/90
X% = 5%
It would be 9720 because 18 times 45 would be 810 then times that by 12 would equal 9720.
1) Convert 4% to decimal = .04
2) Multiply the purchase by that decimal
.04(56.70) = $2.27
C
Answer:
17.60
Step-by-step explanation:
Look at the room carefully, the length of the room is 11 feet
And the height = 10 feet
The area of the 4 walls of the room = 4( 11×10) = 440 sq ft
Area covered by each roll = 25 sq ft
= 440/25 = 17.60 rolls
Therefore we require 17.60 rolls to cover a rectangular room on all four sides.
