Distance between two points, d, is given by

where: (x1, y1) = (2, 2) and (x2, y2) = (5, 5)
Answer: 1080 degrees
Step-by-step explanation:
Answer:
t:

meaning any number can substitute t and it would be the same answer.
Answer:
first top left graph? 12×4 is 48 so that puts it about right
Answer:
52 quarters, 42 dimes
Step-by-step explanation:
Let's call the number of quarters q, and the number of dimes d.
q+d=94
0.25q+0.1d=17.20
Subtract q from both sides of the first equation to isolate d:
d=94-q
0.25q+0.1(94-q)=17.20
0.25q+9.4-0.1q=17.20
0.15q=7.8
q=52
d=94-q=42
Hope this helps!
