A long distance call costs $0.22 for for the first minute and $0.15 for each additional minute. How long did Carlos talk if his billets $3.52? Write the equation and solve it for m

add .22 and .15 and get .37 then subtract that from 3.52 and get 3.15 that is already two minutes the continue subtracting 15 and you would have 20 minutes and no change so 22 is the answer

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.
