Answer:
8.89 gallons per hour
Step-by-step explanation:
In order to find the rate of change, you need to find the slope of the graph.
To find the slope, you use equation (y2 - y1 ) / (x2 - x1)
The given coordinates are:
(0 hours, 0 gallons)
(4.5 hours, 40 gallons)
Next, plug in the x and y values into the slope equation:
y2 = 40 gallons
y1 = 0 gallons
x2 = 4.5 hours
x1 = 0 hours
Slope = (40 - 0) / (4.5 - 0) = 40 gallons / 4.5 hours = 8.888889 gallons per hour
round to 8.89
200 weeks . Use the equation 100+20x=y and 50+30x=y on Desmond to show where the line intersect and it is 200
MobyMax, because it really tries to make you understand it. If you don’t get enough points, you have to start over again until you get it right.
Answer:
4.6
Step-by-step explanation:
Use sine rule to find the number that belongs to the box.
Thus:
a = ?? (the number in the green box)
b = 5
A = 38°
B = 42°
Plug in the values
Multiply both sides by sin(38)
(nearest tenth)
