Aphone can update 6 apps every 4 minutes. at this rate, how many apps can the phone update in 10 minutes? show your work.

15 apps.

Step-by-step explanation:

Divide 6 by 4, and you get how much apps that phone can do in a single minute. Then multiply that number by 10 and you get 15 apps in 10 minutes.

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.
