Find the distance between those points
diameter/2=radius
distance betwen (x1,y1) and (x2,y2) is

given
(3,7) and (7,3)




D=4√2
diameter/2=(4√2)/2=2√2
radius is 2√2
If half a gallon of milk is 3 dollars then you should be able to buy one gallon for 6 dollars. Therefore 5 dollars can buy 5/6 gallons of milk.
I believe the answer is B but I’m nah for sure
X + 4 = 12
This is because the question gives you everything you require for this sentence to be formed. 12 is the final answer. 4 is added on and

is basically the number that is to be found.
I believe for this question you would subtract how much he spent from how much he sold it for.
This would be 155.00 - (35.00+39.17+36.43).
155.00 - 110.60 = $44.40
Hope this helps!
