Michael deposited $1000 in his bank
account at a simple interest rate of
8% for 4 years
interest:
total:

Interest =$320

Total=$1320

Step-by-step explanation:

principal p =$1000

rate r =8%

time t=4yrs

interest, i =p*r*t/100

=1000*8*4/100

=10*8*4=$320

total amount =p+i

=1000+320=$1320

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.

22.83 repeating

step-by-step explanation:
