Answer:
2 real solutions
Step-by-step explanation:
Since the degree of the polynomial is 2, then there are 2 solutions for the equation, but we don't know if they are both complex or both real.
Since the discriminant is 
, then there are 2 real solutions.
I would say A scale which measures by pounds
Michael took the return trip at a velocity 33.75 miles per hour.
<h3>How fast did Michael drive in his return trip?</h3>
Let suppose that Michael drove in <em>straight line</em> road and at <em>constant</em> velocity. Therefore, the speed of the vehicle (v), in miles per hour, can be defined as distance traveled by the vehicle (d), in miles, divided by travel time (t), in hours.
First trip
45 = s / 3 (1)
Second trip
v = s / 4 (2)
By (1) and (2):
45 · 3 = 4 · v
v = 33.75 mi / h
Michael took the return trip at a velocity 33.75 miles per hour.

We know that
Double number lines<span> are best used to visualize equivalent ratios and describe a ratio relationship between two quantities.
</span>
<span>start with the par 40% - 648 gal and let's calculate the other missing data
to find 10%-------> multiply 648 gal by (1/4)
</span>to find 20%-------> multiply 648 gal by (1/2)
to find 30%-------> multiply 648 gal by (3/4)
to find 50%-------> multiply 648 gal by (5/4)
to find 60%-------> multiply 648 gal by (6/4)
to find 70%-------> multiply 648 gal by (7/4)
to find 80%-------> multiply 648 gal by (8/4)
to find 90%-------> multiply 648 gal by (9/4)
to find 100%-------> multiply 648 gal by (10/4)<span>
</span>Here is what the numbers would look like on a number line. They are lined up.
10% 20% 30% 40% 50% 60% 70% 80% 90% 100%
162 324 486 648 810 972 1134 1296 1458 1620
the answer is
the maximum capacity is 1620 gallons of water.
