This is a vector problem. The distance of drift is in x (horizontal axis).
remember that Sin Ф=opposite/hypotenuse. x represents the opposite side form the angle, and 18 is the hypotenuse.
Sin 2.2°=x/18
18 sin 2.2°=x
.691 ≈x
The ship drifts off course .691 miles every hour. .691 x 5 = 5.69 miles after 5 hours.
I believe its $79. 2.00 times 21 is 42, 1.50 times 34 is 51 and 1.00 times 65 is 65. divide the sum of these three numbers and you get 79.
Answer:
(a) 0.16% = 0.0016
(b) 4 = 400%
Step-by-step explanation:
(a) Write 0.16% as a decimal.
0.16% = 0.16 ÷ 100 = 0.0016
(b) Write 4 as a percentage.
4 = 4 × 100% = 400%
(a) 0.16% = 0.0016
(b) 4 = 400%
