Perry surveyed 60 students at her school and found that 0.45 of the students she surveyed said their favorite class is math. another 35% of the students she surveyed reported that their favorite class is science. how many more students in the survey prefer math over science?

step-by-step explanation:

no of data

divide by no of mode

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.
