moving company:

Total cost = 150 + 5x

taxi service:

Total cost = 20x

For the moving company to be cheaper:

150 + 5x < 20x

150 < 20x - 5x

10 < x

x > 10

given expression to simplify,

$q^{-3}r^0s^{-1}\cdot\: q^3r^{-9}s^0$ $\begin{gathered} q^{-3}r^0s^{-1}\cdot\: q^3r^{-9}s^0 \\ q^{-3}\cdot q^3=1 \\ \: =r^0s^{-1}r^{-9}s^0 \\ =1\cdot\frac{1}{r^9}s^{-1}s^0 \\ =1\cdot\frac{1}{r^9}\cdot\frac{1}{s} \\ =\frac{1}{r^9}\cdot\frac{1}{s} \\ =\frac{1}{r^9s} \\ =r^{-9}s^{-1} \end{gathered}$

What is the selling cost of a jacket that the store buys for $60 if the markup is 12%?

Setler79 [48]

Answer:

$67.20

Step-by-step explanation:

We need to find out how much 1% costs so we can multiply that cost by 12 because it goes up 12%.

60/100=0.6

0.6*12=7.2

Now that we have the markup amount we add it to the actual price of $60 so

60+7.2=$60.20

An English teacher needs to pick 9 books to put on his reading list for the next school year, and he needs to plan the order in

Nikitich [7]

Answer: $4.37\times10^3$

Step-by-step explanation:

Given : Number of choices for novels = 4

Number of choices for plays = 6

Number of choices for poetry books = 5

Number of choices for nonfiction books = 5

Total books =4+6+5+5=20

If he wants to include all 4 novels, then the number of books left to select = 9-4=5

Remaining choices for books = 20-4=16

Number of combinations of n things taking r at a time : $\dfrac{n!}{r!(n-r)!}$

Then, the number of different reading schedules are possible :_

$^4C_4\times^{16}C_5\\\\=\dfrac{4!}{4!(4-4)!}\times\dfrac{16!}{5!(16-5)!}\\\\=(1)\times\dfrac{16\times15\times14\times13\times12\times11!}{120\times11!}\\\\=4368=4.368\times10^3\approx4.37\times10^3$

Hence, the required answer is $4.37\times10^3$ .
