Let's write an inequality, such as follows: x < sqrt(50) < y. Square both sides of the equation. We get x^2 < 50 < y^2. Obviously, x is between 7 and 8. Also notice, that for integers a,b, (ab)^2/b^2, equals a^2. So let's try values, like 7.1. Using the previous fact, (7.1)^2, equals (71)^2/100. So, (7.1)^2, equals 50.41. Thus, our number is between 7 and 7.1. We find, with a bit of experimentation, that the square root of 50, is 7.07.
She bought 6 books in all because if you divide the whole number of all the books in all which is $32 divide that by 4 so..
32 ÷4=8
so thats just the 4 books then she buys 16 more dollars worth that which you then multiply 4 times 8 which give you 16 so you then add the 4 books to the other 2 books spent on the next day
ANSWER: 6 BOOKS IN ALL
Answer:
$69.17
Step-by-step explanation:
.065 x 64.95 ≈ $4.22
$69.17 + $4.22 = $69.17
