Answer:
Sanchez bought 20 books.
Step-by-step explanation:
Represent the total number of books purchased by t. Then:
0.75n = 15. Thus, n = 20.
Sanchez bought 20 books.
What does the variables represent?
The sum of any two rational numbers is a rational number. 0.166, 2/3, and 2 are all rational numbers, so adding them to 1/3 will produce another rational number.
That leaves 2π, an irrational number. The sum of a rational number and an irrational number is always irrational, so 2π will produce an irrational number when added to 1/3.
To find the area, you must use this equation:
A=πr^(<span>2)
</span>π=3.14 r=3<span>
Here are the steps:
1) </span>π(3^2<span>)</span>2) A=28.27
Answer:
A. $154.00
Step-by-Step Explanation:
Okay so, the first step is to get 12% and move the decimal to the left twice like this:
.12
Then, multiply 175 by .12 like this:
175 * .12 = 21
Lastly, subtract 21 from 175 like this:
175 - 21 = $154
