Answer:
There are 16 cows and 24 chickens in the farm.
Step-by-step explanation:
A Cow has 4 legs
Chicken has 2 legs.
Lets take there 
chickens AND,
there are 
number of Cows.
Now we can write two equations for the number of heads and legs.
For the number of heads we can write,
<--------- 1st equation
For the number of legs we can write,
<------ 2nd equation
We can now solve the simultaneous equations to find and
Multiply 1st equation by 2 and deduct it from 2nd equation to remove
⇒
⇒
⇒
⇒
Therefore, there are 16 cows in the farm.
Now we can substitute the value to the 1st equation and find value.
Therefore, there are 24 chickens in the farm.
I am not sure but its might be .125
First we subtract the cost of the music CDs from her savings 1,128 - 72 = 1,056. Next Jasmine wants to know how many video games she can buy with the remainder money. 1,056 ÷ 43 = 24 (rounded). Your answer is A. 24.

Answer:
x is approximately 226.3 feet
y is approximately 308.6 feet
z is approximately 226.3 feet
Step-by-step explanation:
The given parameters of the walls are;
The angle of elevation from the top of the shorter wall to the top of the opposing wall, θ₁ = 20°
From the diagram, the angle of depression from the top of the shorter wall to the bottom of the opposing wall, θ₂ = 45°
The distance from the bottom of the shorter wall to the base of the opposing wall, l = 320 feet
x = The height of the shorter wall = l × sin(θ₂)
∴ x = 320 feet × sin(45°) = 320 feet × (√2)/2 = 160·√2 feet ≈ 226.3 feet
∴ x ≈ 226.3 feet
By observation, we have;
y = x + z × tan(θ₁)
Where;
z = l × cos(θ₂)
∴ y = 160·√2 + 320 × cos(45°) × tan(20°) ≈ 308.6
y ≈ 308.6 feet
z = l × cos(θ₂)
∴ z = 320 × cos(45°) = 160·√2 ≈ 226.3
z ≈ 226.3 feet.
