Help pls!!!!!!!!!!!!!!!!
Anastaziya [24]

ANSWER.


The correct answer is Option A


EXPLANATION.


The real number

\sqrt{35}=5.916079783


to 9 decimal places.


You can see that the decimals are not repeating, neither will they terminate.



Therefore the real number \sqrt{35} is irrational because, the decimal does not terminate or repeat


Also note that,


\sqrt{35}=\sqrt{5} \times \sqrt{7} .


That is,

\sqrt{35} is a product of two irrational numbers, which still gives an irrational number.

Two friends Ana and Juan are buying books by joining the History Book
Travka [436]

Answer:

Ana  spent $17  per book on average.

Juan  spent $14.78  per book on average.

y = $15 + 17x--------- equation 1

y= $10 + 14.78 x------------- equation 2

Step-by-step explanation:

Ana has to pay a yearly fee of $15 to join.

She spends a total of $525 for 30 books.

The amount spent on books = Total amount - yearly fee

                                                 = $525- $15= $510

Price per book on the average = $510/30= $ 17

Ana  spent $17  per book on average.

Juan has to pay a yearly fee of $10 to join.

He spends a total of $350 for 23 books.

The amount spent on books = Total amount - yearly fee

                                                 = $350- $10= $340

Price per book on the average = $340/23= $ 14.78≅ $15

Juan  spent $14.78  per book on average.

The function can be established if y gives the total cost and x gives the number of books

y = $15 + 17x--------- equation 1

y= $10 + 14.78 x------------- equation 2

Juan has a better deal because the yearly fee is less also the price per book is less.
