In a certain desert environment there are a lot of small rodents. there are also happen to be a lot of snakes that feed on the rodents. the ratio of
rodents to rodent eating snakes is 13 to 3 . if there are 4,000 snakes in the area abouy how many rodents are there .

If there are 4,000 snakes in the area then there will be approximately 17334 rodents.

Step-by-step explanation:

To answer the question, we note that the ratio of rodents to rodent eating snakes is 13 to 3. That is

There are 13 rodents for every ≡ 3 snakes or  dividing both sides by 3 we have

13/3 rodents for every 1 snake.

Therefore, multiplying both sides by 4,000, we have

4,000 × 13/3 rodents for 4,000× 1 snake

17,333.3 rodents for every 4,000 snakes

4,000 snakes are present where there are ≈ 17334 rodents

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
