Distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(2,5)...x1 = 2 and y1 = 5
(9,8)...x2 = 9 and y2 = 8
now we sub
d = sqrt ((9 - 2)^2 + (8 - 5)^2)
d = sqrt ((7^2) + (3^2))
d = sqrt (49 + 9)
d = sqrt 58 <===
Answer:
80 students are female
Step-by-step explanation:
21 are male meaning 19 are female
9 are female in French
12 are female in Spanish
total = 40
2x + 40 = 120
2x = 80
x = 40
females' = 80
total = 80
6 times 6 equals 36 while 15 times 2 equals 30 so samantha would make 6 more
