Me ! i'm dying and failing math just awnser this

1.
in another project, researchers caught and tagged 85 sea lions in a bay. later they caught and released 50 sea lions. of those, 9 had tags. estimate the sea lion population in the bay.

about 194 sea lions

about 153 sea lions

about 529 sea lions

about 472 sea lions

2.

the table shows the results of a biologist who captures and tags lake trout, and then sets them free. what is the trout population in the lake?

about 90

about 340

about 130

about 250

3.
a park ranger tags 100 animals. use a proportion to estimate the total population for the sample.

83 out of 125 animals are tagged

95 animals

67 animals

142 animals

151 animals

4.

use the table. estimate the total deer population for year 8.

about 1,815 deer

about 2,467 deer

about 1,934 deer

about 2,081 deer

5.
the total number of ducks in a zoo is known to be 4,109. of these 4,109 ducks, 960 have been marked. if you catch 1,100 of these ducks, how many would you expect to be marked?

Complete the worksheet. use 3.14 for π and round all decimals to the nearest hundredth.find the volume of the composite three-dimensional figure above. important terms are written in bold.1. the pyramid has a square base that is inscribed in the circular base of the cone. draw an image of the composite shape of the base. 2. if the side length of the square base is 8 units long, what is the diameter of the circular base of the cone from the picture in number 1? 3. now that the diameter has been calculated, what is the circular area of the cone? ignore the square base of the pyramid.? 4. what is the formula for volume of a cone? 5.to calculate the volume of the cone, the height is still needed. if the cone has a lateral surface with a length of 13 units, what is the height of the cone? 6.now find the volume of the cone. do not include the empty space for the pyramid. 7.. the side length of the square base of the pyramid is 8 units long. what is the base area of the pyramid? 8.what is the formula for the volume of a pyramid9. since the cone and the pyramid share the same vertex, what is the volume of the pyramid10.using the volume of the cone and the pyramid, find the volume of the composite shape. remember, the pyramid is empty. 11,. referring to the picture in number 1, what is the area of the composite base knowing that the square is empty? 12what is the formula to find the lateral surface area of a cone? (13find the lateral surface area of the cone14what is the lateral surface area shape of the pyramid? what is the formula for its area? 15to find the lateral surface area of the pyramid the length is still needed. calculate the lateral surface length of the pyramid. 16 now that the lateral surface length is known, what is the lateral surface area of the pyramid17. using the lateral surface areas of the cone and pyramid, along with the area of the composite base, what is the total surface area?
