Answer: , Less
<u>Step-by-step-explanation:</u>
This year:
Last year: =
Compare this year's with last years by converting the fractions to decimals:
This year: = 0.288
Last year: = 0.300
This year (0.288) is less than last year (0.300)
The answer should be
12ft^3
12cm^3
12yd^3
12in^3
Note what i actually represents.
i is the very basis of a whole new level of counting. When finding discriminants, we often say that a quadratic has no
real roots if the discriminant is 0. Needless to say, there are roots, they are just imaginary.
, in real terms, is non-existent. That is, there are no numbers in the real number system that when multiplied by itself produces a result of -1. This is what i unit represents.
Let's tackle this problem in smaller steps.
Let's first expand our brackets.
(i - 7i)² = (-6i)² = 36i²
Now, let's distribute the xi.
xi(i - 7i)² = xi(36i²) = 36xi³ =
= -36xi
Price in the sale=£31-10% of £31
price in the sale=£31-(10/100)*£31=£31-(10*£31)/100=£31-£3.1=£27.9
The price in the sale is £27.9
