Slope of (3, 300)(5, 180) in y=mx+b form​
vredina [299]

Answer: ok so if you look at the difference it is 120 in 2 hours so to find 1 hour you divide it by 2, or split it in half and that means 60 and it is Decreasing so c is the answer. As for what y= it is y=-60x+480

60 cubic feet and you start out with 480

Step-by-step explanation:

120/2=60

decreasing

c

And y=-60x+480

What is the depth of water in a tank with 300,000 gallons of water at 70F when the pressure gauge at the bottom of the tank read
chubhunter [2.5K]

Answer:

53.08 ft

Step-by-step explanation:

The pressure at the bottom of the tank, P = ρgh where ρ = density of water = 1000 kg/m³, g = acceleration due to gravity = 9.8 m/s² and h = depth of water in tank.

Since the pressure at the bottom of the tank, P = ρgh, making h subject of the formula, we have

h = P/ρg

Since P = 23 psig = 23 × 1 psig = 23 × 6894.76 Pa = 158579.48 Pa

Substituting the values of the other variables into h, we have

h = P/ρg

h = 158579.48 Pa/(1000 kg/m³ × 9.8 m/s²)

h = 158579.48 Pa/(9800 kg/m²s²)

h = 16.18 m

h = 16.18 × 1 m

h = 16.18 × 3.28 ft

h = 53.08 ft
