James blish wrote a new star trek book. he receives 5% royalty based on total sales of the book. the book will sell for $10.00. based on previous book sales, it is estimated gross book sales will be $4,045,300. how many books are estimated to be sold?

  404,530

Step-by-step explanation:

  total revenue = (revenue per book)×(number of books)

Dividing by the coefficient of the variable, you get ...

  (number of books) = (total revenue)/(revenue per book)

  = $4,045,300/$10

  = 404,530

About 404,530 books are estimated to be sold.

answer:      

step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
