$7.25-$2.85= $4.40
$4.40/8= $0.55
Each orange costs $0.55
Answer:
2 mph
Step-by-step explanation:
time = distance / speed
Let c represent the rate of the current. Then the upstream rate of the boat relative to the shore is (5c -c) = 4c, and the <em>upstream time</em> is ...
... 12/(4c) = 3/c.
Likewise, the downstream rate is (5c +c) = 6c, and the <em>downstream time</em> is ...
... 12/(6c) = 2/c.
The <em>total time</em> is the sum of upstream and downstream times:
... 3/c +2/c = 2.5
... 5/c = 2.5 . . . . . . combine terms
... 5/2.5 = c = 2 . . . multiply by c/2.5
Answer:
3x x 2y/ 115=75
Step-by-step explanation:
First you have to find 3x of 2y whch is 500 and didvide it bye 115 which is 75
The correct answer is B: 4/45
reasoning:
how to get the answer is simple. first you have to find a common factor. the only common factor in this chart of 15 is 45. even from then you have an obvious answer and can eliminate all other possible answers. :)
If you add all the sides of whatever shape your dealing with, it will give you the perimeter. Just add up all the sides.
