Jay has $8 l. he wants to buy a book for $ 7.50 the sales tax is 6% does he have enough money? explain your reasoning

Jay does have enough money. 6% of 7 dollars and 50 cents is 45 cents. when the whole cost is added together the total comes to be 7 dollars and 95 cents. That would leave Jay with 5 cents remaining

The book is $7.50, and the sales tax is 6%. We just multiply 7.50 times 0.06, which is 0.45. So the tax on the book would be 45 cents. Next, add 7.50 with 0.45. This gives us 7.95. The cost of the book after sales tax is $7.95. He brought $8 with him. So yes, he does have enough money to buy the book, and he would get 5 cents back as change

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

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.
