11. The average height of 4 buildings is 20 meters. If 3 of the buildings are
each 16 meters tall, what is the
height, in meters, of the fourth
building?
A. 32
B. 28
C. 24
D. 22

32

Step-by-step explanation:

avg=20m

total height= 20*4 =80

three building height =16 *3=48

4th=80-48=32

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

y > 1/3x

y < = -x + 4

hope this : )
