Will give maggie has 7 tiles with pictures of plants and 2 tiles with pictures of animals. maggie keeps all the tiles on a mat with the pictures hidden and mixes them up. she then turns one tile face up and finds the picture of a plant on it. she removes this tile from the mat and turns over another tile without looking. what is the probability that the second tile that maggie turns over has a plant on it?

75.0%

Step-by-step explanation:

7/9 tiles w/ plants

2/9 tiles w/ animals

Maggie takes a tile with a plant on it, and moves it away from the mat. Our new fractions are going to be...

6/8 tiles w/plants

2/8 tiles w/ animals

6 ÷ 8 = 0.75 x 100 = 75.0%

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
