Answer:
The bookstore receive 9 boxes.
Step-by-step explanation:
How many ounces are in a pound? 16! SO 16 times 4 = 64. So Nancy needs 64 ounces in all. So 28 plus 10 = 38 that's still not enough, so lets add some more 38 plus 10 = 48 still not enough, add some more 48 plus 10 plus 10 = 68. So lets add up how many bags we need. So in all with her 28 that she already has, we need 4 bags.
Step-by-step explanation:
7.50= (1 + x/100 ) × 5.50
7.50/ 5.50 = 1+x/100
x/100 = 0.36
x= 36.36%
ANSWER:
6_34/99
STEP:
So yes. When a decimal is repeating, you can take the repeating number (most likely a decimal) and put 99 under it. Since 99 cannot be solved, you put 99. So, 34/99. Though we are not finished. There is still the whole 6 number left. So, you do 6_34/99.
Proof:
10x=6.6...
-x=-0.6...
9x=6
x=6/9=1/3.
