Answer:
<h2>P = 6.25n</h2>Step-by-step explanation:
The problem says that each set costs $6.25, and <em>n </em>refers to sets of pencils.
So, we know that "per" refers to multiplication, because if each set of pencil costs $6.25, then a <em>n </em>quantity of pencils will be the sum of $6.25 <em>n </em>times, which is the definition of multiplication. So, the equation that correctly determined the price is:
The price is $6.25 per set of pencils, that is what this equation says.
Therefore, the right answer is the second one.
Answer:
5/4
Step-by-step explanation:
To do this you must know that by definition secant is:
Furthermore:
Based on this information we know that 3 = opposite and 5 = hypotenuse. Assuming this is a right triangle we can determine the adjacent side by Pythagorean Theorem.
Where c is the hypotenuse, a is adjacent and b is opposite. Therefore,
And so the adjacent side of this triangle is 4. Going back to the definition of secant we can now know that:
