Steve stayed after school for extra activities 55% of the 180 school days this year. How many days did Steve stay after school?

musickatia [10]

Answer:

11/20 or 99/180 days

Step-by-step explanation:

55/100 converted to ?/180

180/100=1.8

so you would do the same on the numerator which is 55*1.8=99

99/180= 33/60=11/20

Evaluate (6 + 2i) / (3 –i ). 5/4 + 6/4i 8/5 + 6/5i 20/8 + 12/8i 16/9 + 12/9i

Yuki888 [10]

We are given with a complex no. and need to simplify it , so let's start !!!

Let's assume that :

${:\implies \quad z=\sf \dfrac{6+2\iota}{3-\iota}}$

Now , Rationalizing the denominator or in other words multiplying and dividing ${z}$ by the conjugate of the denominator

${:\implies \quad z=\sf \dfrac{6+2\iota}{3-\iota}\times \dfrac{3+\iota}{3+\iota}}$

${:\implies \quad z=\sf \dfrac{(6+2\iota)(3+\iota)}{(3-\iota)(3+\iota)}}$

${:\implies \quad z=\sf \dfrac{6(3+\iota)+2\iota (3+\iota)}{(3)^{2}-(\iota)^{2}}\quad \qquad \{\because (a-b)(a+b)=a^{2}-b^{2}\}}$

${:\implies \quad z=\sf \dfrac{18+6\iota +6\iota +2(\iota)^{2}}{9-(-1)}\quad \qquad \{\because (\iota)^{2}=-1\}}$

${:\implies \quad z=\sf \dfrac{18+12\iota -2}{10}}$

${:\implies \quad z=\sf \dfrac{16+12\iota}{10}}$

${:\implies \quad z=\sf \dfrac{16}{10}+\dfrac{12\iota}{10}}$

${:\implies \quad {\bf \therefore}\quad \underline{\underline{z=\bf \dfrac{8}{5}+\dfrac{6}{5}\iota}}}$

Hence , Option B) (8/5) + (6/5)i is correct :D
