64/2=32-12=20 Barry has 20 butterflies left in his collection
Answer: A. EOA and DOS and also
B. SOE and DOA
Step-by-step explanation:
If you look at angle EOA without regarding line OB, you will notice that it is directly opposite to angle DOS.
The same applies for angle SOE and DOA so they are vertically opposite.
(60x2)+30 = 150 miles
30 = 1/2 of 60 which is half an inch
60 x2 because he travels 2 inches
Answer:

Step-by-step explanation:
defition of slope(m) of a line:

A=(-1,-5)=(Xa,Ya) then Xa= -1 and Ya= -5
B=(3,-3)=(Xb,Yb) then Xb=3 and Yb= -3

Answer:
B
Step-by-step explanation:
ABD (half of the rectangle) is a right-angled triangle.
so, Pythagoras applies.
c² = a² + b²
c is the Hypotenuse (the baseline opposite of the 90 degree angle) and in our case the line BD.
a and b are the 2 sides enclosing the 90 degree angle. in our case here the lines AD and AB.
so,
BD² = AD² + AB² = (6-1)² + (5-2)² = 5² + 3² = 25 + 9 = 34
BD = sqrt(34)
