18 centimetres is a metric measure.
It is a RATIO not an exact amount. For every 18 units (whatever units of VOLUME you are using) of fuel, you add 1 unit of oil.
44.09 pounds. The actual conversion of 1 kilogram is equal to 2.204622622 pounds. For everyday use, rounding to 2.2 should be enough. One pound is 0.45359237 kilogram, or 0.45 kg for everyday use.
18 tonnes (metric tons, same as 1000 kilograms) are 39683 pounds.
There are 36 inches in a yard. Therefore, 18 inches is equal to 18/36 = 0.5 yards.
You don't need to use Avogadro's number, you need the mass of the molecule in atomic units. Mass / molecular mass = moles eg for water, 36 grams / 18 atomic units = 2 moles
18 fl oz=
force= 0.1, time= 18
1.8 or 1&4/5
18 x 28.5 x 54 is equal to 27,702 cubic units.
It is a RATIO not an exact amount. For every 18 units (whatever units of VOLUME you are using) of fuel, you add 1 unit of oil.
54 divided by 3 is equal to 18. 18+6 is equal to 24.
The two that have a circumference of 18 pie are a radius of 9 units and a diameter of 18 units.
Slope is equal to the change in y divided by the change in x (also known as "rise over run"). If a slope is 18 , then it "rises" 18 units, for every 1 unit of x.
One possible solution is: 18 = 44 x .4 + .4
As a product of its prime factors 2*3*3 = 18.
It is impossible to answer the question without knowing what you stride is. You do not specify the units used for 18. Centimetres? Decimetres? Inches?
Assuming that the fact that it is a rectangle means that it cannot be a square, then it can have any value in the interval (0, 20.25) square units. This depends on whether the rectangle is a long thin shape or a near-square.
