You by a t shirt at the fair that costs the owner $12,but your markup is 30%. Tax is 7%. How much money do you owe
Ulleksa [173]

Answer:

The final price of money of t shirt that I own = $ 16.69

Step-by-step explanation:

Given in question as ,

The t shirt cost to the owner = $12

The markup percentage = 30%

So, now the cost price of t shirt = 30% of 12 + 12

                                                    = 3.6 + 12 = $15.6

Tax which is added now            = 7%

So, new cost of t shirt = 7% of 15.6 + 15.6

                                     = 1.092 + 15.6  =$ 16.69

Hence , the final price of money of t shirt that I own = $ 16.69   Answer

A student factors a^6 - 64 to (a^2 - 4)(a^4 + 4a^2 + 16). Which statement about (a^2 − 4)(a^4 + 4a^2 + 16) is correct?
Lorico [155]
So that equation was definitely correct...

When you expand the equation in the bracket you'll find out that you'll get a^6 + 4a^4 + !6a^2 - 4a^4 - 16a^2 -64. then your final result will be a^6 - 64

This??? What is wrong with it?
ELEN [110]

Answer:

15.8 sq. in. of paper will be required.

Step-by-step explanation:

The problem is that a drinking cup does not have a cover, so only the lateral surface area counts.

I.e. We need only the first term.

A = pi r l = pi * 1.5 * sqrt(3^2+1.5^2)

= 15.81 sq. in.
