Mercury poisoning is dangerous overload of mercury within the body. A major source of mercury within the body, A major source of
mercury poisoning is consuming fish that contain mercury. Certain fish are more prone to having higher levels of mercury than others. The pie chart shows the distribution of four breeds of fish at a hatchery. The hatchery has approximately 6,000 fish. A biologist from the Centers for Disease Control and Prevention randomly test 5% of each breed of fish for mercury content. Her findings are shown in the following table. Based on the biologist's findings, if a single salmon is randomly selected from those that were tested, what is the probability that this particular fish would have a dangerous mercury level?
A) 0.001
B) 0.004
C) 0.02
D) 0.08
A) 0.001
B) 0.004
C) 0.02
D) 0.08

Because this is a right angle triangle, we can use the Pythagorean theorem to find the missing leg.
The Pythagorean theorem is this:
The Pythagorean theorem tells us if you square both the legs then add them up together, you will get the length of the hypotenuse squared.
We know one leg is 24 and the hypotenuse is 26. Plug them into the equation.
24^2 + b^2 = 26^2
Solve for b.
24^2 + b^2 = 26^2
576 + b^2 = 26^2
576 + b^2 = 676
b^2 = 100
Take the square root of both sides.
b = 10
So, the other leg of the triangle is 10 units long.
