Answer:
Step-by-step explanation:
12 = 60% of x = 0.6x
x= 12/0.6= 20
Paper had 20 shapes. He cut out 12 shapes; 8 shapes remain
Answer: d = 29 miles
Step-by-step explanation:
S11°W = 259° on a unit circle
N75°E = 15° on a unit circle
x separation after two hours
x = 2(8cos15 - 18cos259) = 21.179 miles
y separation after two hours
x = 2(8sin15 - 18sin259) = 19.7398 miles
total distance between them is
d = √(19.7398² + 21.179²) = 28.9518... ≈ 29 miles
Answer:
5/12, 3/8, 5/16
Step-by-step explanation:
Answer:
900
Step-by-step explanation:
set both options equal to each other so we know the intersection.
30000 + 20t = 21000 + 30t
now solve for t.
10t = 30000-21000
t = 90000/10
t = 900
