How to tax things:
In this case, lets say the state tax is 7%.
Shen you buy something, lets say some shoes. For example lets say the price is 60.99
With the 7% tax, move the decimal point two times to the left: 7 -> .07
Multiply .07 by the total price
60.99 * .07 = 4.27
Then add this amount to the total price
60.99 + 4.27 = 65.26
This is how you tax

Answer:
x = 8
y = 4sqrt(3)
Step-by-step explanation:
Your knowledge of special triangles tells you the side ratios of a 30°-60°-90° right triangle are ...
1 : √3 : 2 = 4 : y : x
Multiplying the reduced ratios by 4 gives ...
4 : y : x = 4 : 4√3 : 8
That is, ...
x = 8
y = 4√3
Answer:
Step-by-step explanation:
the simple interest formula= principal* interest rate*time
simple interest : 100000*%2*2 years
simple interest= 4000 dollars
compound quarterly : A=principal(1+r/4)^t
since it is quarterly and have 4 quarters in a year, and 8 in two years.
compound quarterly: 100000(1+0.03/4)^8=106159.88
it is better to invest with compound interest because it add 6159 dollars in two years to the investment of 100000 dollars.
the difference between the interest: 6159.88-4000=2159.88
The last one is rational because it is a terminating decimal.
