Its simple what you do is you subtract not divide because if you where dividing you would be putting something into groups equally and not Addison because your not trying to find how much in all so it would be Subtraction another way is to see if there is how many more or How much more so if you see that then you know that its Subtraction! Hope this helps!:)
Answer:
5,720,000 Sq Feet.
Step-by-step explanation:
They are asking the Area of a Trapezoid
Equation =( base + base / 2) x height
Lets first set it up. We know that A-B is 200 feet. & D-C is 260. They are both the bases.
So if you multiply them (200 x 260) You will get 52000.
Now we divide that by 2. (52000 / 2 = 26000)
Now it says the straight line is 220. I think this refers to the height.
Now we multiply 26000 x 220. Which is 5720000.
Its a pretty big number, but that is the answer! :)
Hope this helps!
First, plug in -3 for the y value.
-3=2x²-10x
Then, add 3 to both sides.
0=2x²-10x+3
Use the quadratic equation to solve
(-b+-√b²-4ac)/2a
You get 4.68 or 0.32
You still have to check your answer to see if there is an excluded value.
Both values check.
Answer:
D. 38%
Step-by-step explanation:
3/8 as a percentage is 37.5% and that is rounded to 38%! :) 37% is close but it is not rounded making it not the best estimate, therefore it is not correct.
