Answer:
55135 lbs (rounded to the nearest pound)
Step-by-step explanation:
diameter of tank = 15 ft
Radius = 15/2 =7.5
volume of hemisphere = 2/3 ×π× 7.5³=883.5729
total weight of water = 62.4 × 883.57 = 55134.768
55134.768 rounded to the nearest pound is 55135 lb

Answer: <span>y - 37.5 = 2.5 ( x - 7)
Explanation:
1) The point-slope form is has this form:
y - y1 = m (x - x1)
Where m is the slope or rate of change and x1, y1 are the coordinates of the point.
2) you are told that the the rate of change of water (m) is 2.5
m = 2.5
3) The point is given by that after 7 min the rain barrel contains 37.5 gallons. This is:
x1 = 7
y1 = 37.5
</span>4) Replace those value in the point-slope model:
y - 37.5 = 2.5 ( x - 7)
That is the point-slope model or equation.
