At Brian’s Bookstore, 0.3 of the shelves hold mysteries, 25% of the shelves hold travel book and 7/20 of the shelves hold childr
elena-s [515]

Children books covers the most shelf space in the store

<em><u>Solution:</u></em>

From given,

Shelves that hold Mysteries = 0.3

Shelves hold travel book = 25 %

Shelves hold children’s books = \frac{7}{20}

To find: Type of book that covers the most shelf space in the store

You cannot compare values which are in different forms, so you need to convert.

Let us convert the given values into decimal form

Shelves hold travel book = 25 %

Percentage can be converted to decimal by dividing by 100

\rightarrow 25\% = \frac{25}{100} = 0.25

Shelves hold children’s books = \frac{7}{20}

\rightarrow \frac{7}{20} = 0.35

<em><u>Which type of book covers the most shelf space in the store?</u></em>

Now we have converted them into decimal form

Shelves that hold Mysteries = 0.3

Shelves hold travel book = 0.25

Shelves hold children’s books = 0.35

0.35>0.3>0.25

We can clearly see that, 0.35 is the highest decimal

Therefore, children books covers the most shelf space in the store

In the diagram, the measure of angle 2 is 126°, the measure of angle 4 is (7x)°, and the measure of angle 5 is (4x + 4)°. A tran
kramer

Answer:

The correct option is C

C) 76°

Step-by-step explanation:

The question is incomplete because the figure is not given. I have attached the figure of the same question below. Consult it for better understanding.

We can see in the figure that <2 and <4 are opposite angles, therefore these are equal.

<2 = <4

126 = 7x

x = 18

Similarly we can also see that <5 and <7 are also opposite angles, therefore they are equal too.

<7 = <5

<7 = 4x+4

Substitute x=18

<7 = 4(18) + 4

<7 = 76°
