Joan Barrett has $10,000 in a savings account which pays 6.5% annual interest. She is thinking about buying ten $1,000 bonds which pay 8% annual interest. How much
more annual interest will the bonds eam than the savings account?

Bonds will earn $150 more than the savings account

Step-by-step explanation:

at 6.5%  for  $10,000 savings

The interest is  0.065* 10,000= $650  interest annually

For the bonds,

0.08 * 10,000 = $800

Bonds will earn $800 - $650 = $150 more than the savings account

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.
