Lest say that The book had been sold x copies in the period of June 1990-June 1995. And we know that the book had been sold 152*x/100 copies in the period of June 1995–June 2000. By June 2000 in total 3843 book had been sold. Therefore number of the copies that sold in the period of June 1990-June 1995 is:

$252*x/100=3843\\x=1525$

number of the copies that sold in the period of June 1995-June 2000 is:

$152*x/100=2318$

For the period June 2000–June 2005 2318*2=4636 book had been sold.

You are a dress maker and buy many of your fabrics overseas. You have been given a new design for a dress that each dress

pshichka [43]

Answer:

Total yards = 19.685 yards

Total cost = $442.9125

Step-by-step explanation:

Fabrics per dress = 1.5 meters

Number of dresses = 12

Total fabrics needed = 1.5 meters × 12

= 18 meters

Convert 18 meters of fabrics into yards

18 meters = 19.685 yards

Cost of fabric per yard = $22.50

Total cost of fabrics in yards = 19.685 yards × $22.50

= $442.9125

$\bf \cfrac{x^3+5x^2+3x-10}{x+4}\impliedby x+4=0\implies x=\stackrel{our~divisor}{-4}\\\\
-------------------------------\\\\
\begin{array}{r|rrrrrrr}
-4&&1&5&3&-10\\
&&&-4&-4&4\\
--&&--&--&--&--\\
&&1&1&-1&\boxed{-6}&\leftarrow remainder
\end{array}
\\\\\\
1x^2+1x^1-1+\frac{-6}{x+4}\implies x^2+x-1+\frac{-6}{x+4}$
