Using an equation, we found that 75% of 104 is equal to 80% of 97.5. The number that made these percentages equal was found to be 97.5.
To find the unknown number, we can setup an equation using percentages and solve for the unknown. The problem states that 75% of 104 is the same as 80% of some number. So, we can write this as an equation: 0.75 * 104 = 0.80 * X. Solving this equation will give the value of X.
First, calculate the value of 75% of 104, which is 0.75 * 104 = 78. Now, replace this value into the equation: 78 = 0.80 * X. To solve for X, we divide 78 by 0.8, which gives us 97.5.
Therefore, 75 percent of 104 is the same as 80 percent of 97.5.

As per the given data, he value of c that makes a perfect square trinomial is c = 9.
A trinomial is a polynomial composed of three terms or monomials in elementary algebra.
To determine the value of c that makes a perfect square trinomial, we need to use the formula:
In this case, we want to find two numbers a and b such that:
Expanding the right-hand side, we get:
Comparing the two expressions, we see that:
The linear coefficient of x is 2a
The constant term is
Therefore, we need to find a number a such that 2a = 6 and a^2 = c. Solving for a, we get a = 3, and substituting into a^2 = c, we get c = 9.
Therefore, the value of c that makes a perfect square trinomial is c = 9.
