Answer:
10/72 or 0.14
Step-by-step explanation:
There are 72 marbles in total and 10 of them are green. So, it is 10/72 or 1.388 rounded to the nearest hundredth is 0.14.
Since the plane descends 1,300 feet per minute it would descend 19,500 feet after 15 minutes (1,300 x 15 = 19,500) Subtract this from the plane's initial altitude 32,000 and the new altitude will be 12,500. (32,000-19,500=12,500)
It's the1st: 4 cm/10 cm because:
4/10 = 2/5 . and because they have the SAME UNIT (cm)
24.5x.18=4.41
$4.41 is how much you save with the discount. You subtract this amount from the regular price.
24.5-4.41=20.09
The sale price of the item should be $20.09
