Answer:
62 square units
Step-by-step explanation:
Top or bottom is 5 x 3, surface area is 15
front or back is 3 x 2, area = 6
left or right is 5 x 2, area = 10
so total area is 2*(15 + 6 + 10) = 62 square units
Step-by-step explanation:
Against the wind, the wind works against the speed. With the wind, the wind aids the speed.
4(p - w) = 2416
4(p + w) = 2896
p - w = 604
p + w = 724
2p = 1328
p = 664 mph
664 + w = 724
w = 60 mph
sin θ = 3 / 7 = .429
sin^2 θ + cos^2 θ = 1 trig identity
9/49 + cos^2 θ = 1
cos^2 θ = 40 / 49 = .816 cos θ = .903
Check .429^2 + .903^2 = 1
cos .903 = 25.4 deg
In the second quadrant sin = +, cos = -, tan = -
So 25.4 deg in the second quadrant = 180 - 25.4 = 154.6 deg
Check:
sin 154.6 = .428
cos 154.6 = -.903
tan 154.6 = -.475
The answer is 0.008. Hope it helped! Stay safe
Answer:
5
Step-by-step explanation:
He can buy 5 boxes of light bulbs..
20 x 5= 100
He only has 120 to spend - the shipping = 110
He can't get another box of lightbulbs. Therefor he can only buy 5!
