Let the age of Vera be 'x' years
So the age of Linda is '2x' years
Now Tanya is 4 less than 4 times Linda
So age of Tanya = 4(2x) -4 = 8x -4 years
So total age of Vera , Linda & Tanya
= x + 2x + 8x - 4
= 11x - 4
But it is 2 less than 9 times Vera's age
11x - 4 = 9x + 2
11x - 9x = 4+2
2x = 6
x = 3
So Vera's age = 3 years
Linda's age = 2(3) = 6 years
Tanya's age = 8x - 4 = 8(3) - 4 = 24-4=20 years
Tanya is 20 years old.
Answer:
6 pints of white paint she used to paint her bedroom walls.
Step-by-step explanation:
Joy uses 9.5 pints of blue paint + white paint.
Joy used 3.5 pints of blue paint.
So, white paint used = total paint - blue paint used
Plug in the known values into the equation.
White paint used = 9.5-3.5 =6 pints
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
