Answer:
The dolphin statue is 86% copper, while the bird statue is 83% copper, making the dolphin sculpture more coppery.
Step-by-step explanation:
Since an artist combines copper and other metals to make bronze, and a bronze sculpture of a dolphin contains 43 g of copper for every 7 g of other metals, while a bronze sculpture of a bird contains 83 g of copper for every 17 g of other metals, to determine which sculpture is more coppery the following calculation must be performed:
Dolphin:
43 + 7 = 50
50 = 100
43 = X
43 x 100/50 = X
86 = X
Bird:
83 + 17 = 100
100 = 100
83 = X
83 x 100/100 = X
83 = X
Therefore, the dolphin statue is 86% copper, while the bird statue is 83% copper, making the dolphin sculpture more coppery.

The solutions for the quadratic equation 9x² - 6x + 5 = 0 are A. 2 complex roots
To determine the the type of roots the quadratic equation 9x² - 6x + 5 = 0, we use the quadratic formula to find the roots.
So, for a quadratic equation ax + bx + c = 0, the roots are
With a = 9, b = -6 and c = 5, the roots of our equation are
Since the roots of the equation are (1 + 2i)/3 and (1 - 2i)/3, there are 2 complex roots.
So, the solutions for the quadratic equation 9x² - 6x + 5 = 0 are A. 2 complex roots
