The cost of a book is 90.5 and the tax is 4% what is the new cost

$94.12

work:

let's start by finding the tax.

step one: convert the percentage into a decimal by dividing it by 100.

4 / 100 = 0.04

next, multiply your total by the tax

$90.5 x 0.04 = 3.62.

next, add the tax to the original price to see your new total.

$90.5 + $3.62 = $94.12

so, your total with tax would be $94.12.

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.
