Write 3000 milliliters in scientific notation?
3*103 mL but you could, just as easily write 3 L (that is the beauty of the SI system).
What is 1.2 l - 200 m?
1.2 l - 200 m = -198.8
The perimeter of a rectangular field is P feet The width of the field is 200 feet less than its length In terms of P what is the length of the field in Feet?
P = 2 x (L + W), so L + W = 100 ie P/2 = L + W W = L - 200 so P/2 = L + L - 200 = 2L - 200 therefore L = P/4 + 100
What two numbers add up to 200 and have a difference of 84?
(200 - 84)/2 = 58 and (200 + 84)/2 = 142 For futher explication, see below. Call the lesser and greater of the two required numbers l and g respectively. the, from the problem statement, l + g = 200 and g - l = 84. Rearrange the first of these equations to give g = 200 - l and substitute this expression into the second of the equations to result in g - (200 - g) = 84, or 2g - 200 = 84, or g 284/2 or 142. l is then (200 - 142) or 58.
What is the number of significant figures in 0.0004 L?
The number of significant figures in 0.0004 L is 1. In scientific notation, trailing zeros to the right of the decimal point are considered significant. Therefore, in this case, only the non-zero digit (4) is significant.
