You are looking for the perimeter of the pool. The perimeter of rectangles can be measured by using the formula 2W + 2L = P (2 * width + 2 * length = perimeter). Using the formula, 2(40) + 2(20) = P, 80 + 40 = P, P = 120. The answer is C. 120 yards.
Answer:
A. x+ 1 < 17
Step-by-step explanation
Customers = x persons
Operator = 1 person
Total = x + 1 persons
Total persons must be less than 17.
The inequality is
x + 1 < 17
Answer:
proportional
Step-by-step explanation:
look at the line
2x + y = -4
y = -2x - 4
differentiate:
y' = -2
m=-2 perpendicular = -1/m = -1/-2 = 0.5, x=2 y=-8
y=mx+c
-8=0.5(2) + c
-8 = 1 + c
-9 = c
y = .5x - 9
OR you can use y-y_1 = m(x - x_1), where x_1 = 2, y_1 = -8, m = 0.5
y - -8 = 0.5(x - 2)
y + 8 = 0.5x - 1
y = 0.5x - 9
same answer either way
