Answer:
Step-by-step explanation:
the passengers of hawaiian airlines in 2018 were 1.800.000, and for Northwest airlines 192.500.000 (delta)
We replace this number in the equation :
Hawaiian : 0,990 +0.683 x (number of passengers) =
0.990 + 0.683 x (1.800.000) =12294012
Northwest airlines: 0,990 +0.683 x (number of passengers) =
0.990 + 0.683 x (195.000.000) = 131477501
Answer:
A. I can't quite see the question, but I'm pretty sure it's A
Step-by-step explanation:
Sin(A) = 1/3
Sin^2(A) + Cos^2(A) = 1
(1/3)^2 + cos^2(A) = 1
1/9 + cos^2(A) = 1
cos^2(A) = 1 - 1/9
cos^2(A) = 8/9
cos(A) = √(8/9)
√8 = √(2 * 2 * 2) = 2√2
√9 = 3
cos(A) = 2√2/3
Answer:
x+x=2x
Step-by-step explanation:
I would estimate 643 - 189 by rounding 643 to the tens place and 189 to the hundreds place.
643 => 640
189 => 200
Now you can subtract 200 from 640.
640 - 200 = 440
