Answer:
D. p + q = 7
Step-by-step explanation:
The slope of AB is ...
mAB = (y2 -y1)/(x2 -x1) = (1 -4)/(6 -p) = -3/(6 -p)
The slope of BC is ...
mBC = (q -1)/(9 -6) = (q -1)/3
We want the product of these slopes to be -1:
mAB·mBC = -1 = (-3/(6 -p))·((q -1)/3)
-(q-1)/(6 -p) = -1 . . . . cancel factors of 3
q -1 = 6 -p . . . . . multiply by -(6 -p)
q + p = 7 . . . . . matches choice D
Answer: (pt 1) 454.5 gallons. (pt 2) $1,390.77
Step-by-step explanation:
PART ONE:
33 · x = 15,000 · 1
33x = 15,000
x = 
x = 454.5 (rounded)
PART TWO:
454.5 · 3.06 = 1,390.77
