The answer to it would be C.
The answers are in the picture below.
You get the cost and multiply it by how many books she bought.
$5.63 and multiply it by 9.
or you can add up $5.63 nine times.
The answer is $50.67

- [Right Triangles Only] Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use PT to solve for the missing side length.
<u>Step 2: Identify Variables</u>
Leg <em>a</em> = 72
Leg <em>b</em> = 65
Hypotenuse <em>c</em> = <em>x</em>
<em />
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitute [PT]: 72² + 65² = x²
- Exponents: 5184 + 4225 = x²
- Add: 9409 = x²
- Isolate <em>x</em>: 97 = x
- Rewrite: x = 97
Answer:
3/12 = divide 3 to get the lowest number possible (In this case 1, so 3 divided by 3) and then divide the bigger number by same amount you've divided the smaller number (12 divided by 3 is 4, because 4 x 3 = 12). So our answer is 1/4. I'm too lazy to go in depth, but basically, 3 (4 times) is 12, so 3 takes up 1/4th of 12.
