An angle is the union of two rays that share a common endpoint. The rays are called the sides of the angle
Answer:
y = 3x + 8
Step-by-step explanation:
y = mx + b
m = slope
slope = change in y / change in x = (44 - 38) / (12 - 10) = 6/2 = 3
y = 3x + b
Now substitute any value from the table to find b. Let's use (10,38)
y = 3x + b
38 = 3(10) + b
38 = 30 + b
8 = b
so equation is y = 3x + 8
Original volume = 2.5 million liters.
After evaporation, the remaining volume is 2 million liters, therefore
Evaporated volume = 2.5 - 2 = 0.5 million liters.
Percent of water evaporated = 100*(0.5/2.5) = 20%
Answer: 20%
[7-(5-6(2)]+4+2
[7-(-1(2)]+4+2
[7- (-2)]+4+2 = [7+2]+4+2
9 + 4 + 2 = 15
