15
Step-by-step explanation:
Answer:
The angle of depression for the flight part is approximately 0.2604 degrees
Step-by-step explanation:
The given altitude at which the helicopter is flying = 50 meters
The horizontal distance of the helicopter from the helipad = 11 kilometers = 11,000 meters
The angle of depression = The angle of elevation = Arctan(Altitude/(Horizontal distance)
Therefore;
The angle of depression for the flight part = Arctan(50/(11,000)) ≈ 0.2604 degrees
Start by taking the information we know, and write equations to represent the realationships:
1) "1/8 lbs less flour to make bread than to make cookies"

2) "1/4 lb more flour to make cookies than to make brownies:

3) "she used 1/2 lb of flour ro make bread"

From here you can solve for

using back substitution.
Notice, 3 decimals, so, we can just use 3 zeros, thus
The lateral area is expressed as the product of the perimeter of the base and the height. While the surface area is the sum of all areas. The lateral area and the surface area of the box is calculated as follows:
LA = Ph
P = 2l + 2w = (2 x 17) + (2 x 5) = 44 cm
LA = 44 cm x 3.12 cm = 137.28 cm
SA = 2(lw + wh + lh)
SA = 2[(17x5) + (5x3.12) + (17x3.12)]
SA = 307.28 cm
Thus, the lateral area and the surface area are 137 cm and 307 cm, respectively.
