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.

You would get the annual salaries by dividing each total salary by the number of years it took to earn it. For example, to get the physician's annual salary, you would divide 5,610,000 by 30 to get an answer of $187,000.

Please find &lt;TQU in the question above ​
Mumz [18]

Answer:

<TQU = 72°

Step-by-step explanation:

<WQT = 60°

=> <WQT = <UYX <u><em>(corresponding angles)</em></u>

=> <UYX = <YUV <u><em>(alternate angles)</em></u>

=> <YUV = <UQR <u><em>(corresponding angles)</em></u>

So, <UQR = 60°

Now,

<PQT+<TQU+<UQR = 180° <u><em>(angles on a straight line add up to 180°)</em></u>

48° + <TQU + 60° = 180°

<TQU + 108 = 180

Subtracting 108 from both sides

<TQU = 180-108

<TQU = 72°

What do I do for this​
Pavlova-9 [17]

Answer:

The answer is C

Step-by-step explanation:

OK, so you know the equation y = mx + b?

To find the slope, divide rise/run

Since the line is going down, that means the slope is negative.

See which y has x = 0

In this case it’s -1

so it has to be C
