Answer 1

a) Magazines

b) 30%

c) 5%

Step-by-step explanation:

Given the pie chart in the attached image.

a) The category that accounts for one-fifth of the publisher's total revenue is;

`(1)/(5)*360^(\circ)=72^(\circ)`

The category that amounts to approximately 72 degrees is Magazines.

b) The percentage of the total revenue comes from Nonfiction and Textbooks combined.

they both combine to approximately 100 degrees.

`\begin{gathered} (100)/(360)*100\approx28\text{\%} \\ to\text{ the nearest 10 \%;} \\ \approx30\text{\%} \end{gathered}`

c) Given that the revenue from poetry is approximately 10% of the total revenue. Nonfiction is approximately one-half of poetry on the graph.

Therefore, the percentage of the total revenue from Nonfiction is;

`(1)/(2)*10\text{\%}=5\text{\%}`
