Answer:
Step-by-step explanation:
i² = -1

Formula being mx+b= 15x+150
Slope would be 15 & y-intercept being 150 since that is where you started.
The answer should be 22.5
Square root of 100 = 10 cm. Next, 10*2 = 20^2 = 400 ft. Next, convert cm into ft, which would make 100 into about 3.3 ft. The ratio would then be about 3/400. Does that help?
