Answer:
13: 10
21: 20
29: 30
Step-by-step explanation:
The formula for determining the pressure, p, exerted on an object at a depth, h, below the surface of a liquid is p = s + dgh, where s is the atmospheric pressure, d is the density of the liquid, and gas the acceleration due to gravity.
p = s + dgh
dgh = p - s
h = (p - s)/dg
Which formula represents h in terms of p, s, d, and g? Formula B is correct.
7x-4=3x+ 8
-3x of both sides 4x-4=8
plus 4 to both sides 4x=12
12 divide by 4 = 3
hopeful that helps
Answer: m1 m2 and m5 all equal to 135 as well
While m3 m6 and m4 are 45
Why: since they are on a line the two angles together should equal 180. So 180- 135= 45
