HELP: The kilopascal is a unit of measure for atmospheric pressure. Suppose the atmospheric air pressure at sea level is about 98 kilopascals. For every​ 1000-m increase in​ altitude, the pressure decreases about 11.1​%. What is the approximate pressure at an altitude of 4000 ​m?

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
