<u>Answer:</u>
There are 243 ducks in the preserve.
<u>Explanation:</u>
Given:
In a wildlife preserve, 45 ducks are captured, tagged, and released.
Later, 200 ducks are examined, and two of them are tagged.
To Find:
To estimate how many ducks are in the preserve =?
Solution:
Now, we know that, out of 200 2 ducks are tagged, which means remaining 198 ducks are untagged.
Now, total ducks count = ducks with tags + ducks with out tag
Total ducks count = 45 + 198
Total ducks count = 243
Hence, there are 243 ducks in total.
Answer:
Yes it is true.
Step-by-step explanation:
If you go on and solve for x, you get 3. I got this by subtracting the 4 from both sides, then getting 15x=45. Then I divided both sides by 15 and got x=3. If you plug that in, you get 4+45=49. This proves to be true.
There are 5280 feet in a mile.
5280/33 = 160
Each post is spaced 160 feet.
m < DAB + m < ADC = 180 (because ABCD is a parallelogram)
so m < ADC = 180 -112 = 68 degrees
Therefore m < ADB = 68 - 27 = 41 degrees (answer)
Answer:
O 30, 36, 42
Step-by-step explanation:
6 = 1 × 6, 12 = 2 × 6, 18 = 3 × 6, 24 = 4 × 6, ? = 5 × 6 = <u>30</u>, ? = 6 × 6 = <u>36</u>, ? = 7 × 6 = <u>42</u>
