H = 3000 - 40m (starts at 3000...decreasing at 40 ft per minute
h = 1200 + 50m (starts at 1200...rises 50 ft per minute
Answer: (1,-1)
Step-by-step explanation:
- You can multiply the first equation by -1
- Add the equations.
- Solve for x, as following:

- Substitute the value of x into any of the original equations and then you must solve for y:

Therefore, the solution is: (1,-1)

Answer:
shaded/square = (50π cm²)/(400 cm²) = π/8
Step-by-step explanation:
The quarter circle has area ...
A = (1/4)(πr²) = π/4(20 cm)² = 100π cm²
The half-circle has area ...
A = (1/2)(πr²) = π/2(10 cm)² = 50π cm²
Then the area of the shaded portion is ...
shaded = 100π cm² -50π cm² = 50π cm²
__
The area of the square is ...
A = s² = (20 cm)² = 400 cm²
Then the ratio of interest is ...
shaded/square = (50π cm²)/(400 cm²) = π/8
Just scan it, there’s an answer for it already I’m pretty sure
