Answer:
y = -(1/7)x + 1
Step-by-step explanation:
![3x + 21y = 21 \\ 21y = 21 - 3x \\ y = \frac{21 - 3x}{21} \\ y = 1 - \frac{1}{7} x \\ y = - \frac{1}{7} x + 1](https://tex.z-dn.net/?f=3x%20%2B%2021y%20%3D%2021%20%5C%5C%2021y%20%3D%2021%20-%203x%20%5C%5C%20y%20%3D%20%20%5Cfrac%7B21%20-%203x%7D%7B21%7D%20%20%5C%5C%20y%20%3D%201%20-%20%20%5Cfrac%7B1%7D%7B7%7D%20x%20%5C%5C%20y%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B7%7D%20x%20%2B%201)
Volume = (PI * r^2 * h) / 3
r^2 = (3 * Volume) / (PI * h)
r = Square Root (3 * Volume) / (PI * h)
The answer to the problem is A
It's D: (0,0)
This is because when you put 0 in for x your y value will equal 0 and that is one of your answers, so it's the point (0,0)
Answer:
8 floors
Step-by-step explanation:
The number of employees is directly proportional to the number of floors that each building has.
The first building has 32 floors and it occupies 189 employees. Therefore:
189 α 32
=> 189 = k * 32 = 32k
where k = constant of proportionality
=> k = 189/32
The new building has 50 employees, therefore:
50 = kN
where N = number of floors
=> 50 = 189/32 * N
N = (50 * 32) / 189 ≅ 8 floors
The new building should have 8 floors
