19 1/2. I just solved a problem like that
Convert the percent into a decimal 25% divided by 100 and do the same for both then add 9$ and all of the other decimals you get

Area of a Circle: A = πr²
Step-by-step explanation:
*Note: A semicircle is <em>half</em> a full circle.
<u>Step 1: Define</u>
Radius <em>r</em> = 10 cm
<u>Step 2: Solve for </u><em><u>A</u></em>
- Rewrite Area of Circle Formula: A = 0.5πr²
- Substitute in <em>r</em> [Area of Semicircle Formula]: A = 0.5π(10 cm)²
- [Area] Evaluate exponents: A = 0.5π(100 cm²)
- [Area] Multiply: A = 50π cm²
We have been given a proof about how angles PCQ and ABC are complimentary. There we need to find the correct missing step.
If you look carefully at the proof in place of [Missing Step], then you will notice that we have to give reason about how angles OCP and ABC are equal.
Only choice which is talking about angles OCP and ABC is 4th choice.
Which shows that OCP and ABC are corresponding angles.
Hence 4th choice <u>"For parallel lines cut by a transversal, corresponding angles are congruent, so ∠OCP ≅ ∠ABC.</u>
Now I'm not completely sure of this answer but by my calculations the member can visit at least 36 times with $42.
