Answer:

$46.42

Step-by-step explanation:

a=price after discount (without sales tax)

a/55=20/100

100a=55·20

100a/100=1,100/100  (the 1,100 is from the 55·20)

You get 11 and then you have to subtract 11 from 55.

55-11=44, so a=44

Then you multiply 44·0.055         (you get 0.055 because you have to make 5.5% a decimal.  You get 2.42.

You add 2.42 and 44 and you get $46.42

The secret number has a 7 in the ones place. The tens number is an odd number
Lana71 [14]
This really is left up to you as long as you have an odd number in the tens place and a 7 in the ones place. How big (or small) the number is is up to you. As long as it is at least 17, it's pretty much up to you.

Mrs. Elizondo runs around a 400-meter track at a constant speed of 250 meter per minute. How many minutes does it take Mrs. Eliz
anastassius [24]

Answer: See explanation

Step-by-step explanation:

From the information, we are told that Mrs. Elizondo runs around a 400-meter track. If she runs 4 laps, the total meters will be:

= 400 × 4

= 1600 meters

Since she uses a constant speed of 250 meter per minute. The number if minutes taken to complete the 4 laps will be gotten by dividing 1600 by 250. This will be:

= 1600 / 250

= 6.4 minutes

= 6 minutes + (0.4 × 60 seconds).

= 6 minutes 24 seconds

A bookshelf contains 5 different mathematics textbooks, 4 different engineering textbooks, and 2 different history textbooks. Ho
Sidana [21]

Answer:

11!

Step-by-step explanation:

Since there are no restrictions, the books can be arranged in any order.

there are 11 books in total.

5+4+2 = 11.

hence, the short answer is: 11 !

11! = 11\times10\times9\times8\times7\times6\times5\times4\times3\times2\times1

an explanation for this is:

if we have 11 spaces in the shelf to put the books in

_ _ _ _ _ _ _ _ _ _ _

how many available spaces do I have to put the 1st book in? 11

hence i'll write 11 for the first place.

11 _ _ _ _ _ _ _ _ _ _

now, how many available spaces do I have to put the 2nd book in? since one book is already placed, i have 10 remaining spaces. hence i'll put 10 in the 2nd place.

11 10 _ _ _ _ _ _ _ _ _

i'll continue this until i have no books left. I'll do the last one here.

how many spaces will i have if i have placed all book in the shelf but one?

11 10 9 8 7 6 5 4 3 2 _

ofcourse, I will have only one space left! hence, i'll write

11 10 9 8 7 6 5 4 3 2 1

finally, once i'm done with this. I'll multiply all the numbers to get my answer for all the possible arrangements to place the books in the shelf.

a shorter way to write all these multiplications is : 11!
