5 % 8,000 decreases to 400 by 5 %
Answer: 160
Step-by-step explanation: She gave her sister one fifth of the collection; one fifth written as a percent is 20% (I did one and divided it by five). To turn 20% to a decimal I didved by 100 to get 0.20. I multiplied 200 and 0.20 and got 40. 40 is the amount of shells given to her sister, so you would subtract 40 from 200 to find how many shells were left. 200-40=160.
The power of the given radicand 7 sqrt(3)^4 is 2. The "power" means the exponent that the radicand is raised to. Although the number is raised to the power of 4, the square root still has to be considered, because taking the square root of a number is equal to raising it to the power of 1/2. Therefore, the power is 4/2, or 2.
If you pay $400 down, plus $80 for the next 12 months, that means you're paying (80*12)+400 which is equal to $1360. You're saving $100 by paying the entire total up front.
