Step-by-step explanation:
Small Box:
9 dollars for 12 pounds
Per pound cost is:
9/12 = $0.75 per pound
Large Box:
18 dollars for 30 pounds
Per pound cost is:
18/30 = $0.60 per pound
Better deal is large box.
To make the deals same, we can change the number of pounds in the large box. We can lessen it so it becomes the same ratio as dollars to pound.
Small box was
9 to 12
Large box is 18 dollars to WHAT?
18 is double of 9 so, "WHAT" should be double of 12, which is:
12 * 2 = 24
So, we can change large box "30" pounds to "24" pounds.
So, the ratio becomes (cost per pound):
18/24 = $0.75 per pound (same)

I don't see the photo. Can't help OOF
Step-by-step explanation:
3 and what?
if it is 3 and 5 than the answer would be 15
The legnth is irrelivant
we know that
Circumference=2 times pi time radius
c=40
40=2 times pi times radius
divide both sides by 2
20=pi times radius
divide both sides b pi
20/pi=radius
the radius is 20/pi cm or aproximately 6.366199048 cm
