Unit Imaginary Number The "unit" Imaginary Number (the equivalent of 1 for Real Numbers) is √(−1) (the square root of minus one). In mathematics we use i (for imaginary) but in electronics they use j (because "i" already means current, and the next letter after i is j).
-1= i
If Both carpenters working together hours or 2.1 hours will take to build one shed.
Step-by-step explanation:
The given is,
First carpenter estimates that it will take him 3 hours to build a shed
Other carpenter estimates it will take him 7 hours to build a shed
Step:1
Formula to find 1 hour work of carpenters (Ref. Dr. R.S. Aggarwal book)
One hour's work =
Where, n - Number of working hours
From the given,
First carpenters one hour work =
Other carpenters one hour work =
If both are working together,
One hour work of both carpenters =
=
One hour work of both carpenters
First carpenter and second carpenter will complete to build the shed in
= hours = hours
Result:
If Both carpenters working together hours or 2.1 hours will take to build one shed.
A cube has equal sides if they are 2÷ 1/2 each then L×W×H would be (2÷ 1/2)^3. To divide fractions we multiply the reciprocal.
2÷ 1/2 = 2/1 × 2/1 = 4
4×4 = 16×4= 64
answer is V = 64 inches cubed.
