Answer:
Step-by-step explanation:
Distance of (-3,4) to origin = √((-3)^2+4^2) = 5
sinθ = 4/5
cosθ = -3/5
tanθ = 4/(-3) = -4/3
cscθ = 1/sinθ = 5/4
secθ = 1/cosθ = -5/3
cotθ = 1/tanθ = -3/4
Answer:
<em>About 900 cans not stamped in 3 hours</em>
Step-by-step explanation:
<u>Proportions</u>
Sally found that 150 cans were not stamped in the 1/2 hour trial run.
Following the same proportion in time, we can say:
150 cans not stamped in 1/2 hour. Multiplying by 2:
300 cans not stamped in 1 hour. Multiplying by 3:
900 cans not stamped in 3 hours
About 900 cans not stamped in 3 hours
Answer:
