area \:  = \pi {r}^{2} \\  circumference  = 2\pi \: r
where r = radius
\pi {r}^{2}  = 28.26 \:  {yd}^{2}  \\  {r}^{2}  = 28.26 \div \pi \\  {r}^{2}  = 8.99 = 9 \\  \sqrt{ {r}^{2} }  = r  =  \sqrt{9}  = 3
circumference = C
c = 2\pi \: r = 2(3) \times \pi \\  = 18.85 \: yd = 18.9 \: yd

gregori [183]

165\15= number of tubs

165 divided by 15 equals the amount of the tubs that he sold.

(I assume the two different name things, isaac&dominic, is a mistake since there isnt any information for Dominic)

Rock-music sales represented 24.8% of the total music sales in 2000. By 2007, rock-music sales represented 32.4% of the total mu
baherus [9]

Answer:

Unit Rate of Change = 1.27%

Step-by-step explanation:

In 2000, t=1 and Total Music sales = 24.8%

In 2007, t=7 and Total Music sales = 32.4%

The Slope  m=\dfrac{32.4-24.8}{7-1} =\dfrac{7.6}{6}=1.27\%

The Unit Rate of Change is 1.27% and it means that the Total Music Sales Increased by approximately 1.27% every year.

Nora had already read 30% of the book before her teacher assigned it to the class. She is choosing between two options to finish
guapka [62]

Answer:

Let p represent the # of pages in the book.  Then, Nora has already read 0.30p pages and has 0.70p pages left to read.

If she reads 25% pages/night, that means reading 0.25(0.70)p pages per night, or 17.5 pages/night.  If 28% p/n, that means 0.28(0.70)p pages/night, or 19.6p pages/night.

How many nights will it take Nora to finish the book if she reads 25% of 7/10 of the book per night?  Without any calculations, we can answer this by "4 nights, since she reads 1/4 of the unread portion of the book per night."

If she reads 28% of 7/10 of the book per night, that will require fewer nights:

First night:  28%

Second night:  28%  

Third night:  28%

 Total:  3(28%) = 84%

This leaves 16% to read on the final night.

This is one interpretation of what I think is a poorly worded question.

The author of this question might have meant reading 25% of the remaining unread pages per night, which leads to a different answer.
