Answer:
160
Step-by-step explanation:
If out of 30 7th graders, 12 own a dog then when you have 400 of them, 160 will have a dog as well.
The way I did this was by 400/30: which was 13.3 repeating. I then mutliplied this number by 12, to find the final answer of 160.

8 units to the left and 5 units up.
Just pick any point on the blue triangle and count how many you move to get to that same point on the red triangle.
Answer:
The height of the seat at point B above the ground is approximately 218.5 feet
Step-by-step explanation:
The given parameters are;
The radius of the Ferris wheel, r = 125 feet
The angle between each seat, θ = 36°
The height of the Ferris wheel above the ground = 20 feet
Therefore, we have;
The height of the midline, D = The height of the Ferris wheel above the ground + The radius of the Ferris wheel
∴ The height of the midline = 20 feet + 125 feet = 145 feet
The height of the seat at point B above the ground, h = r × sin(θ) + D
By substitution, we have;
h = 125 × sin(36°) + 145 ≈ 218.5 (The answer is rounded to the nearest tenth)
The height of the seat at point B above the ground, h ≈ 218.5 feet.
