18/35 = ~51%
You would get an F.
Answer:
1.62m^2
Step-by-step explanation:
From the problem statement, the scale of the drawing is
1cm:45cm (meaning that 1cm on the drawing represent 45cm in reality ofr actual)
first,let us convert 20cm to the actual drawing
20cm in actual will give 20*45=900cm
to meters =900/100= 0.9m
Secondly let us convert 40cm to the actual drawing
20cm in actual will give 40*45=1800cm
to meters =1800/1000= 1.8m
Now we can calculate the actual area in meters we have
area= 0.9*1.8
area= 1.62m^2
My choice to reflect this would be over the y axis. That would be (-1,3) for the bottom left hand corner on the original image.
Area = length x width = 3/4Length*3/5Width=9/20LW. The total area covered by the entire floor is the full length x width which is just LW. Therefore 9/20 of the floor has been covered
3x-21=12
add 21 to both sides to get 3x alone.
3x=33
divide both sides by 3
and you get:
x=11
