Andrea studied for a total of 6 3/4 hours during the three days before her math test if she studied for the same amount of time each day how much time did she spend studying each day

2.25 or 2 1/4 hours

Step-by-step explanation:

To answer this, we simply have to divide the number of hours spent studying by the number of days before the test. And since 6 3/4 is in fraction form, we will convert to decimal because it makes it easier to multiply that way:

6.75 ÷ 3 = 2.25

So, Andrea studied for 2.25 or 2 1/4 hours each day before her test

Hope this helps :)

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.

i will u if u answer my question in math
