Answer

500

Step-by-step explanation:

If the biologist tags 25 birds and lets them go, and then catches 100 and 5 of them have the tags, that would mean 20 of them are still out in the wild.

The way to solve this is if you put it into a proportion.

5/100 = 25/x

5x = (100)(25)

5x = 2500

5x/5 = 2500/5

x = 500

5/100=25/500

The sum of three and four tenths and a number is six and six tenths.

Solnce55 [7]

Hopefully I drew what you described.

The 6.6 represents the total of N + 3.4
We subtract the part we know from the whole /sum/total we know to get the other part.
So 6.6 - 3.4 = N
3.2 = N

A rectangle has an area of x^3 + 5x^2 + 5x – 2 square meters and a width of x + 2 meters. Find its length.

musickatia [10]

Answer: x^2 + 3x - 1.

Step-by-step explanation: We need to divide x^3 + 5x^2 +5x-2 by x+2. This is dividing polynomials. Divide each number by x and multiply the quotient by 2 and subtract the answer.

How to put the following in order largest to smallest 0.20.7569%

MakcuM [25]

0.2, 0.75, 60%, 1/2, 1, 1 1/4

60% is the same as 60/100 or 0.6
1 1/4 is the same as 5/4 or 1.25
1/2 is the same as 0.5
Now our list is

0.2, 0.75, 0.6, 0.5, 1.25 and 1

So from largest to smallest your answer would be...

1.25 , 1 , 0.75 , 0.6 , 0.5 , 0.2
