Answer:
15c+3b=66 and 25c+5b=110
Step-by-step explanation:
A quadrant is the area that is divided into the x and y axes
The quadrants in which tan 
and cot are positive are I and III
<h3>How to determine the quadrants</h3>
The tangent of an angle is calculated as:
While the cotangent of the angle is calculated as:
The above equations mean that:
For the tangent and cotangent of an angle to be positive, then the sine and the cosine of the angle must have the same sign.
- In the first quadrant, the sine and the cosine angles are positive.
- In the third quadrant, the sine and the cosine angles are negative.
Hence, the quadrants in which tan and cot are positive are I and III

The price of the computer program is 50 dollars.Since, it is on sale, the current price is now 37.50 dollars.Base on the given choices or options, let's find out which is correct.But, first let's solve this to be able to identify which one is the correct answer:=> 37.50 dollars / 50 dollars = 0.75=> 0.75 * 100% = 75%=> 100% - 75% = 25%.<span>Thus, the discount percentage is 25% and the current price is 75%.</span>
well it is going to be 10,000,000 (000-0000 to 999-9999) minus any number before 100-0000 that would make 9,000,000 legal numbers.
