In a certain bookstore, 30 percent of the books that have been discounted are called bargain books and are priced below $4. If t
svet-max [94.6K]

Answer: the percent of the books in the store that are discounted is 60%

Step-by-step explanation:

Let x represent the total number of books in the bookstore. If the bargain books make up 18 percent of the total number of books in the store, it means that the total number of bargain books in the bookstore is

18/100× x = 0.18x

Let y represent the number of books that have been discounted. 30 percent of the books that have been discounted are called bargain books. This means that

30/100 × y = × 0.18x

0.3y = 0.18x

y = 0.18x/0.3 = 0.6x

The percentage of the number of books that have been discounted would be

0.6x/x × 100/= 0.6×100 = 60%

(Teaser) An angle that measures 6° is drawn on a piece of paper. You are looking at the angle through a×6 magnifying glass, whic
cluponka [151]

Answer:

No change in angle it will remain 6 degrees only.

Step-by-step explanation:

measurement of angle on paper = 6 degrees

power of magnifying glass = a*6

it means that the glass enlarges any thing seen through it by 6 times.

so if you are watching 1 cm object, it will be 1*6 times larger (i.e 6 cm) when seen through the magnifying glass.

It is to be noted that glass changes the size of the object, it does not change the shape of object. Th object will remain similar to the older one.

________________________________________________

Now given that

measurement of angle on paper = 6 degrees

This is a tricky question, here change of size of object is not being asked .

Since angle determines the shape of object , so angle will remain similar to as that on paper only size will get enlarged.

Hence, the measure of angle will remain same i.e 6 six degrees only. It will not change.

only thing will be that the shape of angle will appear larger but there will be no impact on angle.
