Answer:
8 cm
Step-by-step explanation:
Two circles of radii 5 cm and 4 cm intersect at two points D and E.
The distance between their centers (points A and C) is 3 cm.
Consider triangle ACD. In this triangle,
AC = 3 cm (distance between centers)
AD = 5 cm (radius of larger circle)
CD = 4 cm (radius of smaller circle)
So, this is right triangle and therefore, AC is the height of isosceles triangle ADE (triangle ADE is isosceles, because AE = AD).
The height of the isosceles triangle drawn to the base is its median, so CD = CE = 4 cm, hence
DE = 4 + 4 = 8 cm
Answer:
75
Step-by-step explanation:
Let x represent the number of bullfrogs in the population.
We have been given that in a study of the population density of bullfrogs, 25 are captured and marked in the first sampling. Five days later, 30 frogs are captured, 10 of which have marks.
We will use proportion to solve our given problem as:
Therefore, the estimated number of bullfrogs in the population would be 75.
