Step-by-step explanation:
20 percent is the discount. Everything has 100%, so if you take away 20% of the 68$ you will get only the amount of the discount; however, we are looking for the price after the discount. Since 20% is the discount, then perhaps 80% is the cost after the discount is used; therefore, if you multiply .8 which is equal to 80% to 68, you will get the cost after the discount. The answer would be .8(68)=T
Answer:
$10.42
Step-by-step explanation:
Compound interest formula: A=p(1+r/n)^nt
9=p, r=0.05, n=1, and t=3
A=9(1+0.05)^3
A=9(1.05)^3
Plug this into calculator and you get $10.42
Answer:n+5=2n+12, n=-7
Step-by-step explanation:
Answer: If you take the square root of a number that is not a perfect square, it is going to be irrational. And then if you just take that irrational number and you multiply it, and you divide it by any other numbers, you're still going to get an irrational number. So square root of 8 is irrational. You divide that by 2, it is still irrational.
