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

Hannah has 8 over 9 of a pound of birdseed. She put 2 over 3 of a pound of birdseed into her bird feeders. How much birdseed doe

Reptile [31]

8/9 - 2/3 = 8/9 - 6/9 = 2/9 of a pound left

She had 8/9 of a pound of birdseed to begin with. She used 2/3 of a pound of birdseed into her feeders. You have to get a common denominator, would be 9 and when you subtract what she used from what she had you get 2/9 of a pound of birdseed left.
