Answer:
22 feet in centimeters is 670.56
22 inch in centimeters is 55.88
Step-by-step explanation:
The hardware store sells copper pipes for $24 per 5 feet right? so, 5 feet is equal to 60 inches and since you need 6 inches, you divide 60 by 10 to get 6 and also divide 24 by ten and you get 2.4, so the answer is $2.4 for 6 inches of pipe.
Hope this helps!
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
