Complete Question
A drawing of a basement uses the same scale as the example above which is 1 inch to 10 ft. The basement is 28ft wide and 35 ft long. how wide and long is the drawing? show your work
Answer:
2.8 inches wide and 3.5 inches long.
Step-by-step explanation:
Scale drawing
1 inch = 10 feet
= 1 inch/10 feet
For the Width of the basement
The basement = 28ft wide
= 1inch/ 10 feet = x inch/28ft
= Cross Multiply =
10 feet × x inch = 28feet × 1 inch
x inch = 28 feet × 1 inch/10 feet
x = 2.8 inches
The drawing = 2.8 inches wide
The length of the basement = ft long
1inch/ 10 feet = x inch/35ft
= Cross Multiply =
10 feet × x inch = 35feet × 1 inch
x inch = 35 feet × 1 inch/10 feet
x = 3.5inches
Therefore, the drawing is 2.8 inches wide and 3.5 inches long
25% of 150000 is 0.25 * 150000 = 37500
So, they now cost 150000 + 37500 = 187500 and that is the answer you are looking for
Answer:
9.8 cm
Step-by-step explanation:
Volume of a cylinder can be gotten with this formula
V=πr2h
h = height of the oil.
We were told that 3 litres of oil was removed, then, there is a falling in the level of oil by 10 cm, hence the height of the oil is now
h° =( h) - (0.1)
Then the new volume can be calculated as
V°= V - (3×10^-3)
But
volume= (π r2h°)
Then substitute we have
πr2h - 0.003 = π r2 (h-0.1)
If we open the bracket we have
0.003 = (πr2 ×0.1)
πr2=0.003/0.1
Then r=√ (0.03/0.1π)
=9.8 cm
Note that 1L = 10-3 m3
