Answer:
Step-by-step explanation:
We have the following information:
Fredburguer , milkshake
and an order of fries
costs
:
(1)
One Fredburguer is equal to a milkshake plus orders of fries:
(2)
Three milshakes is equal to a Fredburguer plus an order of fries:
(3)
And we are asked: If we have a Fredburguer, a milkshake and two orders of fries, how much do we have to pay?
(4)
Well with the first three equations we have a system of equations to solve. Let's begin by isolating from (3):
(5)
Making (2)=(5):
(6)
Isolating :
(7)
Substituting (7) in (2):
(8)
Isolating :
(9)
Substituting (7) and (9) in (1):
(10)
Isolating :
(11) This is the cost of a Milkshake
Substituting (11) in (7):
(12)
(13) This is the cost of an order of frieds
Substituting (11) in (9):
(14)
(15) This is the cost of a Fredburguer
Substituting (11), (13) and (15) in (4):
(16)
Finally:
This is the cost of a Fredburguer, a milkshake and two orders of fries
The angle for shooting laser gun should be 89.98°.
The vertical height where a tiny but horrible alien is standing is given as 443443443 meters. The horizontal distance of a men in black agent from building is given in the question as 181818 meters. So, let us assume the angle formed to be theta (θ).
Writing the formula for tan theta, that relates the given height and distance
Now, tan θ = vertical height ÷ horizontal distance
Keep the values in above mentioned equation of theta to find the angle.
tan θ =
Performing division to find the tan theta and subsequently calculate the angle
tan θ = 2438.94
θ = tan⁻¹ 2438.94
Calculating tan inverse to find the value of theta
θ = 89.98°
Therefore, the angle for shooting laser gun by a men in black agent should be 89.98°.
