Answer:
the plane's current height above the ocean is 3.42 miles
Step-by-step explanation:
Given that the diagonal distance between the plane and the aircraft carrier is 10 miles.
What we need to find is the vertical distance between the plane and the aircraft carrier which is the plane's current height above the ocean. This can be gotten using sine rule.
For sine rule, you need a side and its opposite angle. For this question the triangle formed is a right angle triangle with diagonal distance, vertical distance and horizontal distance.
let a = diagonal distance = 10 miles
let the opposite angle to the diagonal distance be A = 90° (right angle)
let the vertical distance = b
let the opposite angle to the vertical distance be B = 20°
Sine rule states that
∴
⇒ b = 3.42 miles
Therefore the plane's current height above the ocean is 3.42 miles
We calculate the commission and adding it to the price of the stock to get total cost.
No Price Total Commission Total cost
100 $26.25 0.06 x $2,625 = $157.50 2625 + 157.50 =2782.5
100 $19.32 0.06 x $1,932 = $115.92 1932 + 115.92 =2047.92
40 $9.77 0.06 x $390.80 = $23.45 390.80 + 23.45= 414.25
200 $5.39 0.06 x $1,078 = $64.68 1,078 + 64.68 = 1142.68
100 $33.44 0.06 x $3,344 = $200.64 3,344 + 200.64 = 3544.64
Remember you said the scale shows you 10% heavier.
So that's an increase of 10%
So value = 10% + 100% = 110%
So scale would show 110% of 82
110% of 82
= (110/100) * 82
= 1.1 * 82
= 90.2
OR
We can simply find 10% of 82 and add it to the original 82.
10% of 82
(10/100) * 82
0.1 * 82 = 8.2
8.2 + 82 = 90.2 Same answer as before.
So scale shows 90.2 kg.
