Asign above a sweater says “take an additional 50% off.” the price tag shows a price that is 40% of the regular price. what percent of the regular price is the discounted price (the price after both discounts)?

Say it was 100$. 40% off would make it 60$. Another 50% off would make it 30$. The sweaters price and the end was a total of 70% off as it starts at 100$ and goes down to 30$

Quartile are numbers used to divide a set of data into four equal parts or quarter

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
