Answer: 200cm
Step-by-step explanation:
The center Planck is a square of length 8cm.
The 4 next planks are of 16 cm each
And the next 4 Planks are of 32 cm each.
8 + 4(8×2) + 4(8×4)
8 + 4(16) + 4(32)
8 + 64 + 128
200 cm
Length of the original plank is 200cm
If you miss 9 questions, the how many did you get right?
85 - 9 = 76
So now you got 76 out of 85 correct or 76/85...
Now if you just do the fractional division that is described by the fraction you will get the answer. The fraction bar literally means "divided by", so the fraction means...
76 divided by 85 which equals...
.8941
Now to convert to percentage we multiply by 100 (move the decimal 2 places to the right)
.8941 x 100 = 89.41% Round to nearest one percent...
89%

Answer:
Step-by-step explanation:
The real part is the term not containing i as a factor.
The imaginary part is defined differently, depending on who you read. It is either the coefficient of i (-19), or the term containing i (-19i).
Above, we have shown the results that are obtained from functions designed to give the real and imaginary parts of a complex number.
real part: 14
imaginary part: -19, or -19i
